Collector-emitter breakdown voltage test method (supplement)
The purpose of this test is to determine whether the breakdown voltage of the transistor is greater than the specified minimum limit under specified conditions. A2 Test circuit
The test circuit is shown in Figure A1.
Voltage source
A3 Steps
Collector-emitter breakdown voltage test circuit The current limiting resistor R should be large enough to prevent excessive current from flowing through the transistor and the ammeter. Under the condition of emitter-base open circuit, increase the voltage until the specified test current is reached. If the voltage applied at the specified test current is greater than the minimum limit of V(BR>CEO, the transistor is qualified. Additional notes:
