1. [Amps] Zener Diode needed (score: 1): Author: "Howard Miller" <n2mm@fcc.net>; Date: Sun, 19 Oct 2003 17:52:34 -0400; Hi all.... I am in need of a 12v/50amp Zener diode...I think in a TO-3 case. Anyone have one in their junk box or know where I can get one quickly? 73, Howard, N2MM __________________________________; /archives//html/Amps/2003-10/msg00179.html (6,403 bytes)

If not, I don't think it would be possible to get one in a TO-3 case, as the heat to be removed would be too much. -- "The day Microsoft makes something that doesn; /archives//html/Amps/2003-10/msg00185.html (7,080 bytes)

Re: [Amps] Zener Diode needed (score: 1): Author: rlm <r@somis.org>; Date: Tue, 21 Oct 2003 04:07:48 -0700; ** A string of fwd-biased cheapo 3a rectifiers will survive a 200a surge - such as a HV flashover. A 50w zener will not. Also, zeners do not provide adjustable V and diode strings semi-do. On Monday,; /archives//html/Amps/2003-10/msg00202.html (8,289 bytes)

Re: [Amps] Zener Diode needed (score: 1): Author: "Pat Barthelow" <aa6eg@hotmail.com>; Date: Tue, 21 Oct 2003 19:57:47 -0700; It may be easier to find a 11.5 volt normal size zener and use a power transistor to get the current... I think the Handbook has the circuit, to make a high current Zener from a 1 watter... Pat AA6EG; /archives//html/Amps/2003-10/msg00204.html (8,453 bytes)
6. Re: [Amps] Zener Diode needed (score: 1): Author: peter.chadwick@Zarlink.Com; Date: Tue, 21 Oct 2003 14:15:20 +0100; By choosing the right voltage zeners, an almost zero temperature coefficient can be obtained, which cannot be done with diodes. 73 Peter G3RZP _______________________________________________ Amps mai; /archives//html/Amps/2003-10/msg00206.html (7,352 bytes)

Ny guess is that some anomaly caused the zener to short and if this problem is not addressed, the replacement will e; /archives//html/Amps/2003-10/msg00214.html (9,197 bytes)
8. [Amps] Zener Diode Needed (score: 1): Author: "Bob Maser" <bmaser@tampabay.rr.com>; Date: Sun, 7 Sep 2008 16:34:58 -0400; I need a 5W 56V zener for my Tetrode board. It is a 1N5370B. Anyone have one that they are not using? Also, I believe that zeners can be placed in series to achieve higher voltage. Are there caveats; /archives//html/Amps/2008-09/msg00036.html (6,984 bytes)
9. Re: [Amps] Zener Diode Needed (score: 1): Author: Robert Groh <rgroh@swbell.net>; Date: Sun, 7 Sep 2008 13:42:15 -0700 (PDT); Regarding the 2nd point - yes, you can easily put zeners in series. But the wattages do not need to be the same necessarily - since they are in series, the same current will flow in each one and the; /archives//html/Amps/2008-09/msg00037.html (7,764 bytes)
