Description
The D25F05…D25F10 is a series of high-power fast silicon diodes made in Romania by IPRS Băneasa, listed in the Agenda radioelectronistului (2nd edition, 1989) among the fast silicon switching diodes, with a repetitive peak reverse voltage VRRM of 50…1000 V and a maximum average forward current IFAVM of 25 A [1]. The package drawing is in the Gallery.
The table prints the series as „D25 F05 (R)… …10(R)”, with VRRM 50…1000 V given for the whole series; each code also exists with R [1]. It gives a reverse recovery time trr of 600 ns, IFAVM 25 A at 100 °C, IFSM 275 A at 150 °C, I²t 380 A²s at 150 °C and a junction-to-case thermal resistance of 1.1 °C/W [1]. The column header gives IFAVM in mA (at 25 °C); for this row the value only makes sense in amperes, with its temperature in brackets [1].
Coded as (IPRS Băneasa code for medium- and high-power silicon rectifier diodes, NTR 19036-80) [2]:
| Part | Meaning |
|---|---|
| D | function: diode |
| 25 | average forward current IFAV, in A |
| F | type: fast (N = normal, R = reverse polarity, A = controlled avalanche) |
| 05 … 10 | repetitive peak reverse voltage VRRM: here in hundreds of volts (05 = 50 V), while the coding table writes it in volts |
In the coding table R takes the place of N and means reverse polarity (anode on the base); here it is printed after the code, „(R)” [1][2].
The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the D25F05…D25F10 (9 codes) among the „Fast recovery rectifiers ( IFAVM < 100 A )” 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, TJM) are under Variants [3]. In this table VF and IR are maximum values (at the IF and TJ given), VF0 is a typical value, trr is a maximum (in µs) 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 IFSM 350 A; i²t 610 A²s (elsewhere on this page: IFSM 275 A; i²t 380 A²s) [3].
