Description
The RA032…RA420 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 30–400 V and a maximum average forward current of 20 A [1]. Its codes are in the Variants table; the package drawing is in the Gallery.
The package drawing is not named in the 2nd edition; the 1st edition of the Agenda (1983) calls the same package of the RA diodes „P auto” [1][2].
Each code also exists with R at the end (printed „(R)”); on the package drawing the stud is the cathode for the codes without R and the anode for the codes with R [1].
The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the RA120 and RA220 among the „Standard rectifiers ( IFAVM < 100 A )” of its „Rectifiers” section [3]. The catalog values this page did not have (IFAVM temperature, IF of VF, VF0, rF, TJM) are under Variants [3]. In this table VF and IR are maximum values (at the IF and TJ given), VF0 is a maximum and i²t is printed in kA²s; the codes marked „(R)” are also made with reverse polarity [3]. For all the codes of this table the catalog gives IFRM 70 A; package DO-21 (elsewhere on this page: IFRM 180 A; package P auto) [3].
Measurement conditions (as printed in the table): IFRMSM at Tamb = 90 °C; IFAVM at Tamb = 90 °C; VF at IF = 60 A; IR at Tamb = 150 °C; IFSM for 10 ms.
