Collector-Emitter leakage... LOL
What he's got is a shorted transistor. That's got nothing to do with leakage. Professor www.telstar-electronics.com Bill Eitner wrote: The transistor that heats up immediately is bad (excessive C-E leakage). The DVM test procedure is to use the diode check function. Imagine a transistor as two diodes back-to-back with the base being the common element. Test from base to emitter, and from base to collector. You should only get a reading in one direction on each test (when the base is above either of the other elements), and it should be around 600 mV. |
