Description
The D16A4…D16A14 is a series of controlled-avalanche rectifier diodes made in Romania by IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) with a repetitive peak reverse voltage VRRM of 400…1400 V and a maximum average forward current IFAVM of 16 A, in a DO-4 package [1].
The table prints the series as „D16A4(R)… …14(R)”, with the repetitive peak reverse voltage VRRM, the avalanche voltage VRA (explained in a note to the table) and the non-repetitive peak reverse power PRSM given as ranges for the whole series; each code also exists with R, printed „(R)” after the code [1] (in the coding table of section 27.1.2, R takes the place of N and means reverse polarity [2]).
The table of section 27.5 has no drawings; the drawing of the DO-4 package in the Gallery is the one printed in the rectifier diode table of section 27.1.2 [1].
Coded as (IPRS Băneasa code for medium- and high-power silicon rectifier diodes, NTR 19036-80) [2]:
| Part | Meaning |
|---|---|
| D | function: diode |
| 16 | average forward current IFAV, in A |
| A | type: controlled avalanche (N = normal, R = reverse polarity, F = fast) |
| 4 … 14 | repetitive peak reverse voltage VRRM: here in hundreds of volts (4 = 400 V), while the coding table writes it in volts |
The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the D16A4, D16A6, D16A8, D16A10, D16A12 and D16A14 among the „Controlled avalanche rectifiers” of its „Rectifiers” section [3]. The codes new on this page and the catalog values it did not have (IFAVM temperature, IFRM, VF, IF of VF, VF0, rF, IR) are under Variants [3]. In this table VF and IR are maximum values (at the IF and TJ given), VF0 is a typical value and i²t is printed in kA²s; VRA (min–max) is the avalanche voltage and PRSM the non-repetitive peak reverse power, and IR is given at the maximum TJ; the codes marked „(R)” are also made with reverse polarity [3]. For all the codes of this table the catalog gives IFSM 250 A; i²t 315 A²s (elsewhere on this page: IFSM 180 A; i²t 160 A²s) [3].
Conditions (as printed in the table): IFAVM at T = 125 °C; IFSM at T = 150 °C; I²t at T = 175 °C.
