Original poster: "Gerry Reynolds" <gerryreynolds@xxxxxxxxxxxxx> Hi Terry,Im wondering if peak current is important too. Sorta akin to second breakdown with bipolar transistors. The signature for second breakdown with a CBE transistor is a short between C and E, yet the BC and BE diodes are still there. Peak power can cause localized heating that causes this C to E short.
