Re: #qmx PCB Rev 2 recommended modification #qmx


 

Hi folks,
now that I got my filter sweeps fine after replacing Q508, I want to do the Diode mod.

However, I have no 1N4148 lying around.

What I got at hand that comes closest is a BAW76, specs (and the 1N4148 specs in brackets):
  • Size: DO-35 (same)

  • URRM: 75 V (100V)

  • UF: 1 V (same)

  • IF(AV): 0,15 A (same)

  • IFSM: 2 A (1A)

  • IR: 0,1 ?A (5?A)

  • Temp: -65 ... +175 ¡ãC (same)

What worries me the most are the much lower IR and lower URRM.

Any comments on that? - Will that work or fry the diode and possibly more?

Thanks a lot and Vy73
Stefan.
