Description

The D500N is a series of silicon rectifier diodes made in Romania by IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) with a repetitive peak reverse voltage VRRM of 1400–3000 V and a maximum average forward current of 500 A [1]. Its codes are in the Variants table; the package drawing is in the Gallery.

The table prints the block as „D500 N 1400 T … 3000 T”, with the voltage classes 1400, 1600, 1800, 2000, 2200, 2400, 2600, 2800 and 3000 V; the codes in the Variants table are formed by the coding table of the same section (NTR 19036-80) [1][2].

Coded as (IPRS Băneasa code for medium- and high-power silicon rectifier diodes, NTR 19036-80) [2]:

Part Meaning
D function: diode
500 average forward current IFAV, in A (at the specified ambient temperature)
N type / polarity: N = normal (R = reverse polarity, anode on the base; F = fast; A = controlled avalanche)
1400 repetitive peak reverse voltage VRRM, in V
T package: T = disc (A = wire–wire, B = stud with braided lead, E = flat base with braided lead, T = disc)

Measurement conditions (as printed in the table): IFRMSM at Tamb = 25 °C; IFAVM at Tamb = (100) °C; VF at IF = 2000 A; IR at Tamb = 150 °C; IFSM for 10 ms. Temperatures in brackets are printed in brackets in the table.
