Create a checklist on how to test a PNP transistor?
5 answers
To test a PNP transistor, follow this checklist: Bias the transistor to non-linearity using a harmonic-free alternating signal and compare the base and collector currents at higher harmonics to determine the beta value. Establish continuity test circuits to detect short circuits between the base and emitter or emitter and collector, and measure the collector current at a specific base to collector bias with the emitter open. Use an amplifier tuned to the second harmonic of the oscillator frequency and a detector to analyze the collector to base load voltages for beta measurement. Test for base to emitter short circuits by disconnecting the base from the oscillator and connecting it to a resistor while applying negative bias to the emitter. Measure the collector current I CB0 by breaking the emitter circuit and connecting the meter directly to the base.What is TCAD?
