How to test IGBT?

Hi all,

I need info on how to test IGBT. Can it be tested without being removed from PCB?

limited tests

In board testing is limited to checking for shorts (with the board powe off) Most of the failures are this mode. Use a multimeter.

You can test with the board power on by checking for DC voltages and waveforms. This will reveal opens.

using a multimeter to test IGBT. Is the method same like we test normal NPN transistor.
 

Re: How to test IGBT?

In circuit testing is only for short circuit test (in some cases even not possible). For proper testing and surety has to be removed from PCB.
