Re: Failed IRF510 in BJ

I forgot to address the last question.

Ought not be a one-time protection.
The IRF510 is rated 100V Drain-Source breakdown, and the gate leakage is specified at a up to +/- 20V Gate to Source. So "normal" reverse polarity (due to a short circuit between the headphones - hi) shouldn't damage it.

 Does reverse voltage cause the IRF510 to short out but still pass voltage when the voltage polarity is corrected? It is a ONE TIME protection? Important to know for all of us who might use this form of protection in the future.
