Finding 100A TVS diode?
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: http://diotec.com/tl_files/diotec/fi...heets/bzw065v8 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? Thanks, Dave |

Fagor's slightly larger 5kp version, 8.7 x 9 mm, is rated for 500A surge. There are larger ones available. -- Thanks, - Win |

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