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 specd over 1/2
cycle of 60 Hz sine:

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

Surely the original isnt all that unique a part...? Anyone know of a
direct replacement?

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.
