1. [Amps] HELP: obsolete power zener for a TL-922 (score: 1): Author: ke5c at hot.rr.com (ke5c); Date: Mon Jan 27 19:31:57 2003; Does anyone know of a source for power zeners? I lost the bias zener in an old Kenwood TL-922. It's 7.2 volts at unknow watts, but it carries both grid and plate current which could total near an amp; /archives//html/Amps/2003-01/msg00256.html (7,772 bytes)

A 3A epi rectifier should have about a 150A top 300A surge rating, and so does a 7.5V 50W zener. (Actually a good 50W stud zener is proba; /archives//html/Amps/2003-01/msg00275.html (10,321 bytes)

Failure of this capacitor is usually hastened by 160m RF leaking into the power supply compartment past the too-tiny HV bypass cap of 2000pF.

You normally won't find the surge rating for a zener on a data sheet, since a single-die zener isn't normally tested under surge conditions, it's ch; /archives//html/Amps/2003-01/msg00294.html (8,767 bytes)

However the zeners used by amp mfgs reportedly have a high failure rate and none of them have adjustable Vz. A string of fwd biased Si diodes does the job for this application. - R.
