MIL-STD-704A Transient Absorbers

[ambertec]

Does anyone know of a transient absorbing diode tailored, as it were, to MIL-STD-704A service a'la the 1N5555, but with a higher power capability than the 1N5555? (A lot!! more power capability actually.)

Thank you.

and type Diodes: Transient Suppressor
which will return 17 Companies to inquire about or obtain your diode.

That would be a Transzorb. Two types bi-directional and uni-directional... as per the 1N5555 its a 30Vdc working and 33Vdc minBkDn and 47.5Vdc max Vclamp device. So you will want most likely a uni-directional unit.... Diodes, Inc., General Instrument, and several others (like Panasonic) now make Transzorbs. The 15KP30A is rated for 15KW peak (10 x more power, is that enough???), 30Vdc working, 33.3V minBkDn and 50.7 max Vclamp.

IF you are working on Airborne equip specs then the 704-15K36 and the 704-15K36T are designed to protect the 28Vdc bus to mil spec's Mil-Std-704... use the non-T unit for short spikes and the T unit for "long surges or spikes" in excess of 1 milli-sec. Specs are 31.5Vdc working, 36V minBkDwn, and 51V max Vclamp...

Hope this helps... later

And if you need even more Peak Power then the devices can be placed in parallel, but 2 devices are only rated at 1.4 of the total of 2 devices. At this level you need real short and massive bus bars or real short chassis path connections to keep the peak voltage down. Hope you have a good analog engineer or two on staff...

I'm one... but busy at the moment... LOL.
