Same zener clamping as above. But we avoid it anyway. Unfortunately mik had problem driving this device with UGS=5V. It did not even activate his fuelpump relay (is the Motorola datasheet bad?). It worked from 10V. (what about 6V? HC259 is spec-ed to 6V). Do we misread the datasheet? Datasheet says it should definitely conduct at UGS=5V.

With the IGBT, it is connected to the IGBT's metallic "case" (backside). The FET (FQPF20N06L we use) has a nice electrical insulator coating that reduces the risk of shorting to the alubos case even without an insulator-sheet. '''The insulator-sheet between the IGBT and alubos case is a must for the IGBT''' (old-style mica or TO220 footprint sticker insulator can also be used instead of the big sheet, of course). || || name || connected to case || risk of short to case || insulator-sheet recommended || || '''FET''' || Drain || not on our nice black insulated FET || low || doesn't hurt|| || '''IGBT'''||Collector||'''yes''' || '''high'''|| '''absolutely a must''' || Testing: with the board powered off, measure with DVM (diode mode or resistor measurement) that * the output pin is not connected to alubos case (if it's connected, you have a problem). * the output is not connected to gnd If either seems to be connected, there is a problem. Check that the insulator-sheet is applied correctly.
