10DZ6V8…10DZ180

The 10DZ6V8…10DZ180 is a series of 10 W Zener diodes made in Romania by IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) with nominal Zener voltages of 6.8–180 V and a power dissipation of 10 W, in a DO-4 (F9-M) package [1]. Its codes are in the Variants table; the package drawing is in the Gallery.

The codes are printed „10 DZ 6V8”, „10 DZ 8”, „10 DZ 10” and „10 DZ 12(P)” … „10 DZ 180(P)”; the package drawing notes that the codes with P are in a TO-220 package („cu P în cod - TO 220”) [1]. The „10 DZ 8” has a nominal Zener voltage of 8.2 V in the table [1]. The table gives the Zener voltage VZT (minimum, nominal, maximum), the test current IZT, the differential resistance rZM, the temperature coefficient αVZ and the maximum Zener current IZM [1].

The package drawing also marks the terminals for codes with R: the stud is marked „C / A” and the lead „A (cod fără R) / C (cod cu R)”, i.e. the stud is the cathode for the codes without R and the anode for the codes with R, although the table lists no codes with R [1].

Coded as (IPRS Băneasa code for Zener diodes of 1 W and more, NTR 19036-80) [2]:

Part	Meaning
10	dissipated power PR in W (the coding table lists 1, 4, 10 and 20 W)
DZ	function: Zener diode
6V8 … 180	nominal stabilization voltage VZT in V (standardized values)

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the 10DZ6V8…10DZ180 (18 codes) among the „10 W @ TC = 25 °C voltage regulator diodes” of its „Zener” section [3]; and the 10DZ12P…10DZ180P (15 codes) among the „10 W @ TC = 25 °C voltage regulator diodes” of its „Zener” section [4]. The catalog values this page did not have (TJM) are under Variants [3][4]. 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 = 10 W at TC = 25 °C, TJM 150 °C, DO-4 case [3]. The table of the „P” codes (p. 5-17) has the same columns, with Ptot = 10 W at TC = 25 °C, TJM 125 °C and a TO-220 case [4]. For the 10DZ12P the catalog gives temperature coefficient 6.5 ×10⁻⁴/°C; IZM 730 mA (elsewhere on this page: temperature coefficient 5.7 ×10⁻⁴/°C; IZM 770 mA) [4]. For the 10DZ15P the catalog gives temperature coefficient 7 ×10⁻⁴/°C; IZM 590 mA (elsewhere on this page: temperature coefficient 6.3 ×10⁻⁴/°C; IZM 625 mA) [4]. For the 10DZ18P the catalog gives temperature coefficient 7.5 ×10⁻⁴/°C; IZM 490 mA (elsewhere on this page: temperature coefficient 6.8 ×10⁻⁴/°C; IZM 500 mA) [4]. For the 10DZ22P the catalog gives temperature coefficient 8 ×10⁻⁴/°C; IZM 410 mA (elsewhere on this page: temperature coefficient 7.3 ×10⁻⁴/°C; IZM 415 mA) [4]. For the 10DZ27P the catalog gives temperature coefficient 8.5 ×10⁻⁴/°C; IZM 330 mA (elsewhere on this page: temperature coefficient 7.7 ×10⁻⁴/°C; IZM 335 mA) [4]. For the 10DZ33P the catalog gives temperature coefficient 8.5 ×10⁻⁴/°C; IZM 300 mA (elsewhere on this page: temperature coefficient 8 ×10⁻⁴/°C; IZM 275 mA) [4]. For the 10DZ39P the catalog gives temperature coefficient 9 ×10⁻⁴/°C (elsewhere on this page: 8.5 ×10⁻⁴/°C) [4]. For the 10DZ47P the catalog gives temperature coefficient 9 ×10⁻⁴/°C; IZM 190 mA (elsewhere on this page: temperature coefficient 8.5 ×10⁻⁴/°C; IZM 195 mA) [4]. For the 10DZ56P the catalog gives temperature coefficient 9 ×10⁻⁴/°C (elsewhere on this page: 8.8 ×10⁻⁴/°C) [4]. For the 10DZ68P the catalog gives IZM 140 mA (elsewhere on this page: 135 mA) [4]. For the 10DZ82P the catalog gives temperature coefficient 9 ×10⁻⁴/°C (elsewhere on this page: 9.2 ×10⁻⁴/°C) [4]. For the 10DZ100P the catalog gives temperature coefficient 9 ×10⁻⁴/°C (elsewhere on this page: 9.3 ×10⁻⁴/°C) [4]. For the 10DZ120P the catalog gives temperature coefficient 9.5 ×10⁻⁴/°C; IZM 70 mA (elsewhere on this page: temperature coefficient 9.4 ×10⁻⁴/°C; IZM 77 mA) [4]. For the 10DZ150P the catalog gives temperature coefficient 9.5 ×10⁻⁴/°C; IZM 60 mA (elsewhere on this page: temperature coefficient 9.6 ×10⁻⁴/°C; IZM 62 mA) [4]. For the 10DZ180P the catalog gives temperature coefficient 9.5 ×10⁻⁴/°C (elsewhere on this page: 9.6 ×10⁻⁴/°C) [4].
