Finding 100A TVS diode?

Started by Spare Change February 6, 2017
BZW6-26, 26v TVS unidirectional diode, through-hole, obsolete, n/a.

The original datasheet says that the 600W peak pulse power is measured over 
10/1000 uS waveform, but the 100A forward surge current is spec’d over 1/2 
cycle of 60 Hz sine:

All replacements I see, the surge current is nowhere near 100A or is spec’d 
at 10/1000 uS waveform.

Surely the original isn’t all that unique a part...? Anyone know of a 
direct replacement?

Thanks,
Dave

Fagor (my TVS favorite) uses the same spec. So does ST. Try the -28 version for distributor inventory. Fagor's slightly larger 5kp version, 8.7 x 9 mm, is rated for 500A surge. There are larger ones available. -- Thanks, - Win

It's not shown as obsolete by Diotec. They claim distributor stock of several thousand in PL, DE and SK.

P6KE-30A from ST is a direct replacement, with exactly the same specifications. Klaus
