Exceeding this maximum cutoff current can lead to malfunction or damage of the component. It is typically specified in the component's datasheet and is crucial for proper circuit design and operation.
100nA ICBO - Vce Saturation (Max) @ Ib, Ic
The parameter "Vce Saturation (Max) @ Ib, Ic" in electronic components refers to the maximum voltage drop across the collector-emitter junction when the transistor is in saturation mode. This parameter is specified at a certain base current (Ib) and collector current (Ic) levels. It indicates the minimum voltage required to keep the transistor fully conducting in saturation mode, ensuring that the transistor operates efficiently and does not enter the cutoff region. Designers use this parameter to ensure proper transistor operation and to prevent overheating or damage to the component.

Voltage - Collector Emitter Breakdown (Max) is a parameter that specifies the maximum voltage that can be applied between the collector and emitter terminals of a transistor or other semiconductor device before it breaks down and allows excessive current to flow. This parameter is crucial for ensuring the safe and reliable operation of the component within its specified limits. Exceeding the maximum breakdown voltage can lead to permanent damage or failure of the device. Designers and engineers must carefully consider this parameter when selecting components for their circuits to prevent potential issues and ensure proper functionality.
300V - Transition Frequency
Transition Frequency in electronic components refers to the frequency at which a device can transition from one state to another, typically defining the upper limit of its operating frequency. It is a critical parameter in determining the speed and performance of active components like transistors and integrated circuits. This frequency is influenced by factors such as capacitance, resistance, and the inherent characteristics of the materials used in the component's construction. Understanding transition frequency is essential for optimizing circuit designs and ensuring reliable signal processing in various applications.
50MHz - Frequency - Transition
The parameter "Frequency - Transition" in electronic components refers to the maximum frequency at which a signal transition can occur within the component. It is a crucial specification for digital circuits as it determines the speed at which data can be processed and transmitted. A higher frequency transition allows for faster operation and better performance of the electronic component. It is typically measured in hertz (Hz) or megahertz (MHz) and is specified by the manufacturer to ensure proper functioning of the component within a given frequency range.
