Understanding the configuration is essential for design, troubleshooting, and optimizing electronic devices.
Single - Case Connection
Case Connection refers to the method by which an electronic component's case or housing is connected to the electrical circuit. This connection is important for grounding purposes, mechanical stability, and heat dissipation. The case connection can vary depending on the type of component and its intended application. It is crucial to ensure a secure and reliable case connection to maintain the overall performance and safety of the electronic device.
MAIN TERMINAL 2 - Trigger Device Type
Trigger Device Type is a parameter in electronic components that refers to the type of device or mechanism used to initiate a specific action or function within the component. This parameter specifies the specific trigger device, such as a sensor, switch, or signal input, that is required to activate or control the operation of the component. Understanding the trigger device type is crucial for proper integration and operation of the electronic component within a larger system or circuit. By specifying the appropriate trigger device type, engineers and designers can ensure that the component functions correctly and responds to the intended input signals or conditions.
4 QUADRANT LOGIC LEVEL TRIAC - Voltage - Gate Trigger (Vgt) (Max)
Voltage - Gate Trigger (Vgt) (Max) refers to the maximum voltage level required to trigger the gate of a semiconductor device, such as a thyristor or triac, into the conductive state. When the gate receives this voltage, it initiates the device's conduction, allowing current to flow between its anode and cathode. Exceeding this voltage can lead to unwanted behavior or damage to the component, making it a critical parameter in designing circuits that utilize these devices. Understanding Vgt is essential for ensuring proper operation and reliability in electronic applications.
1.5V - Current - Non Rep. Surge 50, 60Hz (Itsm)
The parameter "Current - Non Rep. Surge 50, 60Hz (Itsm)" in electronic components refers to the maximum non-repetitive surge current that a component can withstand without damage during a single surge event at frequencies of 50Hz or 60Hz. This parameter is important for assessing the robustness and reliability of the component in handling sudden spikes or surges in current that may occur in the electrical system. It helps in determining the level of protection needed for the component to ensure its longevity and proper functioning in various operating conditions. Manufacturers provide this specification to guide engineers and designers in selecting the appropriate components for their applications based on the expected surge current levels.

Current - Gate Trigger (Igt) (Max) refers to the maximum gate trigger current required to activate a semiconductor device, such as a thyristor or triac. It is the minimum current that must flow into the gate terminal to ensure that the device turns on and conducts current between its anode and cathode. Exceeding this value can lead to unnecessary power consumption, while insufficient current may prevent the device from turning on effectively. This parameter is crucial for circuit design, as it influences the selection of gate driving circuits.
5mA - Current - Hold (Ih) (Max)
The parameter "Current - Hold (Ih) (Max)" in electronic components refers to the maximum current required to maintain the component in a latched or on-state after it has been triggered. This parameter is commonly associated with relays, switches, and other devices that have a latching function. It is important because it determines the minimum current that must be supplied to keep the component in its activated state, ensuring reliable operation. Exceeding the maximum Ih value can lead to the component failing to hold its state, potentially causing malfunctions or disruptions in the circuit.
10mA - Current - On State (It (RMS)) (Max)
The parameter "Current - On State (It (RMS)) (Max)" refers to the maximum root mean square (RMS) current that an electronic component, typically a semiconductor device like a thyristor or a transistor, can handle while in the on state without sustaining damage. This value is crucial for ensuring that the component operates safely under load conditions. Exceeding this maximum rating can result in overheating, degradation, or failure of the component over time. It is an important specification for designers to consider when selecting components for a circuit to ensure reliable performance.
4A - Repetitive Peak Off-state Voltage
The Repetitive Peak Off-state Voltage (Vdrm) is a key parameter in electronic components, particularly in devices like thyristors and triacs. It refers to the maximum voltage that can be applied across the component when it is in the off-state without triggering it to turn on. This parameter is crucial for ensuring the proper functioning and reliability of the component in various circuit applications. It helps determine the voltage level at which the component can safely operate without experiencing unintended conduction. Designers need to consider the Vdrm rating to prevent damage to the component and maintain the overall performance of the circuit.
600V - Triac Type
Triac Type refers to the classification of triacs based on their electrical characteristics and applications. Triacs are semiconductor devices that can control current flow in both directions and are commonly used in AC power control. Different types of triacs may have variations in parameters such as voltage rating, current rating, triggering method, and switching speed, making them suitable for specific applications like light dimmers, motor speed controls, and heating regulation. Understanding the triac type is crucial for selecting the appropriate component for a given circuit design.
