R.A.E Thyristors

(1/3) > >>

Hello,
I recently purchased 6 RAE YC450PM thyristors. I plan on using them to discharge a very large capacitor bank into a load. Has anyone ever heard of RAE thyristors? The data sheet states they can withstand pulses up to 28,500 amps. Although the RAE scrs are roughly 1/2 the size of a similar spec'd AEG scr so I have a hard time believing the data sheet. I am going to test them and I'll post the results. I have attached the data sheet to the post. As you can see by the picture I have a few scrs  ;D.

MagicSmoker:
Phase-control thyristors won't be happy in a capacitor discharge application unless there is significant inductance present to limit the dI/dt.

Yep, I have simulated the circuit to make sure my di/dt was much lower than the data sheets. I plan on using a 10uH inductor to limit di/dt to roughly 40amps/uSec.

David Hess:
There are improved thyristor structures which support higher peak currents so it does not surprise me that they could be half the size.  But make sure to apply sufficiency gate drive because low gate drive compromises turn on capability.

floobydust:
Would pulse gate-drive would be bad compared to using DC, in this application? You can hit the gate harder without exceeding gate power dissipation, but between gate pulses the SCR is on its own.
