Description
The 50DZ10…50DZ180 is a series of 50 W Zener diodes made in Romania by IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) with nominal Zener voltages of 10–180 V, in a DO-5 package [1]. Its codes are in the Variants table; the package drawing is in the Gallery.
The book gives only a list, printed „50 DZ 10/12/15/18/22/27/33/39/47/56/68/82/100/120/150/180) — în capsulă DO-5”, without values [1]. The drawing in the Gallery is the same DO-5 (F-10M) drawing as in the table of the 20 W Zener diodes [1].
Coded as (IPRS Băneasa code for Zener diodes of 1 W and more, NTR 19036-80) [2]:
| Part | Meaning |
|---|---|
| 50 | dissipated power PR in W (the coding table lists 1, 4, 10 and 20 W) |
| DZ | function: Zener diode |
| 10 … 180 | nominal stabilization voltage VZT in V (standardized values) |
The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the 50DZ10…50DZ180 (16 codes) among the „50 W @ TC = 25 °C voltage regulator diodes” of its „Zener” section [3]. The catalog values this page did not have (VZ min., VZ max., IZT, rZT, temperature coefficient, IZM, TJM) are under Variants [3]. In this table VZ (min–max) and rZT (max) are given at IZT, and the temperature coefficient in units of 0.0001 1/°C; Ptot = 50 W at TC = 25 °C, TJM 150 °C, DO-5 case [3].
