SMBJ60CA Description

The SMBJ60CA  was created to safeguard sensitive electronic equipment against voltage transients such as those caused by lightning and other transient voltage events.

The SMBJ series is designed to safeguard sensitive equipment from electrostatic discharges and electrical overstress according to  IEC  61000-4-2 and  MIL-STD 883 , method 3015, and IEC 61000-4-4 and 5. Surges of less than 600 W (10/1000 s) are more commonly encountered with this device. Planar technology allows it to be used in high-end equipment and SMPS where low leakage current and high junction temperature are required for long-term reliability and stability.

The SMBJ series comes in SMB packaging.

  • Power Rating

    The "Power Rating" of an electronic component refers to the maximum amount of power that the component can handle or dissipate without being damaged. It is typically measured in watts and is an important specification to consider when designing or selecting components for a circuit. Exceeding the power rating of a component can lead to overheating, malfunction, or even permanent damage.

  • Voltage - Breakdown (Min)

    Voltage - Breakdown (Min) is a parameter used to specify the minimum voltage level at which an electronic component, such as a diode or capacitor, will break down and allow current to flow through it uncontrollably. This breakdown voltage is a critical characteristic that determines the maximum voltage the component can withstand before failing. It is important to ensure that the applied voltage does not exceed this minimum breakdown voltage to prevent damage to the component and maintain proper functionality. Manufacturers provide this specification to help engineers and designers select components that are suitable for their intended applications and operating conditions.

  • Power - Peak Pulse

    Power - Peak Pulse refers to the maximum transient power level that an electronic component, such as a diode or a transzorber, can safely dissipate during a short-duration pulse. This parameter is critical in determining the component's ability to withstand voltage spikes or surges without failure. It is typically expressed in watts and is measured over a specific duration, usually in microseconds or nanoseconds, to reflect the component's performance under peak conditions. Understanding this parameter helps designers select appropriate components for applications where transient conditions are expected.

    The parameter "Current - Peak Pulse (10/1000μs)" in electronic components refers to the maximum current that a device can handle during a transient overvoltage event with a specific waveform, typically a 10/1000μs pulse. This parameter is important for surge protection devices such as transient voltage suppressors (TVS) and varistors, as it indicates the device's ability to divert excess current away from sensitive components and protect them from damage. A higher peak pulse current rating signifies better surge protection capability, making the component more suitable for applications exposed to high-voltage transients or lightning strikes. Designers should carefully consider this parameter when selecting surge protection components to ensure reliable operation and protection of their electronic circuits.

    Voltage - Clamping (Max) @ Ipp refers to the maximum voltage that a component, such as a transient voltage suppressor or diode, can clamp when subjected to a specific peak current (Ipp). It indicates the upper limit of voltage that the component will allow to pass through, effectively protecting sensitive circuits from overvoltage conditions. This parameter is crucial for ensuring that devices are safeguarded against voltage spikes without being damaged. Designers use this specification to select appropriate components for overvoltage protection in their applications.

    96.8V
  • Voltage - Reverse Standoff (Typ)

    Voltage - Reverse Standoff (Typ) refers to the maximum reverse voltage that a semiconductor device, such as a diode or a transient voltage suppressor, can withstand without entering into breakdown. It is typically specified as a nominal value and indicates the voltage level at which the device transitions from its non-conducting state to a conducting state when reverse-biased. Exceeding this voltage can lead to permanent damage or failure of the component. This parameter is crucial for ensuring the safe operating limits of electronic circuits, particularly in protecting sensitive components from voltage spikes.

    Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.

Frequently Asked Questions

How does a transient voltage suppressor diode work?

Transient Voltage Suppressor Diode is a clamping device, so whenever the induced voltage exceeds the avalanche breakdown voltage, it absorbs the excess energy of the overvoltage event, and then it automatically resets after overvoltage condition.

Where should a TVS diode be placed?

Place TVs diode near the edge of the PCB. To enable the excessive surge current to be channeled to the chassis ground before damaging the transceiver, the placement of the TVS diode is also important. It is a good practice to place TVS diodes as close to the edge of the board as possible.

Does TVS diode have polarity?

The -C and -CA diodes are bidirectional, there is no polarity marker. On unidirectional diodes, the color band usually denotes the cathode.

How do you specify a TVS diode?

1. Select a diode with a standoff voltage that is higher than the normal operating voltage. Ensure that the TVS diode maximum clamping voltage is less than the abs max rating of all the devices on the line to be protected. It is important to consider operation during both the transient event (a higher conduction current will result in a higher clamping voltage, for example) and during normal operation when a transient event is not present.
2. Verify that the specified peak current exceeds the expected peak current. Ensure that the diode is specified to handle the required power during a transient event. Diodes that are too small, or are not designed for a given current, may fail and cause the circuit to be destroyed during a surge or EFT event.
3. Calculate the maximum clamping voltage (VCL) of the selected diode. TVS diode datasheets typically list the VCL for a given IPP in the part selection table. For other peak pulse currents, however, this VCL may not be valid. To accommodate other IPP values, the TVS diode manufacturer gives a formula in the datasheet to calculate the VCL. Use this formula to calculate the VCL for a given IPP.
4. Confirm that the calculated VCL is less than the specified abs max rating for the pin.
