MAINTENANCE TYPE OSB 9415 SERIES OSM 9415 SERIES OSS 9415 SERIES ~ N AMER PHILIPS/DISCRETE eSE D MM@ 6653931 0022905 2 mm HIGH-VOLTAGE RECTIFIER STACKS 723-07 Ranges of high-voltage rectifier assemblies, incorporating controlled avalanche diodes mounted on fire-proof triangular formers. They are supplied with M6 studs, The OSB9415 series is intended for application in two-phase half-wave rectifier circuits. The OSM9415 series is intended for application in single-phase or three-phase bridges or in voltage doubler circuits. The OSS9415 series is intended for all kinds of high-voltage rectification. The OSB9415 series and OSM9415 series are supplied with a centre tap (8B32UNC)., The maximum crest working voltages of the 0$89415 and OSM9415 series cover the range from 3 kV to 27 kV, and of the OSS9415 series the range from 4.5 kV to 54 kV, in 1.5 kV steps, Configuration: Fig. 1 OSB9415....A4 Fig. 2 OSM9415....A4 Fig. 3 OSS9415....A 7D centre-tap +Yawu> | Vewe centre-tap 0761 Monn mew. - + - -- ~ ape + 0760 + . , Yaw __ vomSS ean mascatlhls sata OSB 9415 SERIES OSM 9415 SERIES OSS 9415 SERIES N AMER PHILIPS/DISCRETE eSE D ES 6653931 0022906 4 om All information applies to frequencies up to 400 Hz RATINGS T-23 -07 Limiting values in accordance with the Absolute Maximum System (IEC 134) OSB9415 -4] -6]...]|-34] -36A Voltages OSM9415 4 -6 ~34 | 36A Crest working reverse voltage VRWM max. 31 46 ]...125.5 27)OkKV OSS9415 -3] -4]...{-35 | -36A Crest working reverse voltage VRwnM max, 4.5 6]. ..152.5 54 kV mr Currents Average forward current (averaged over any 20 ms period) in free air up to Tamb = 35 OC lE(AV) max. 10 A in oil up to Toi = 35 OC lF(AV) max. 30 A Repetitive peak forward current lFRM max. 450 A Non-repetitive peak forward current t= 10 ms; half sine-wave; Tj = 175 C prior to surge lEsm max. 800 A Reverse power dissipation OSB9415 4 6|}...4,-34] -36A Repetitive peak revetse power dissipation OSM9415 4 -6j...{/-34] -36A t= 10 us (square-wave; f = 50 Hz) Tj = 175 o PRRM max. 9/ 13.5 ]...]76.5 81 kW Non-repetitive peak reverse power dissipation t= 10 us (square-wave) Tj = 25 C prior to surge PRsSM max. 55 82)...] 467 | 495 kW Tj = 175 C prior to surge PrRsw max. 8.5 3[...] 72 77 kW Oss94i5 3 4!)...]-35 | -36A Repetitive peak reverse power dissipation t= 10 us (square-wave; f = 50 Hz) Tp = 175 oC PRRM max. 13.5 187...) 7157 | 162 kW Non-repetitive peak reverse power dissipation t= 10 us (square-wave) Tj = 25 C prior to surge PRSM max. 80] 105]...] 919 | 945 kW Tj = 175 C prior to surge PRsm max. 13 171,..1 1491 153 kW Temperatures Storage temperature Tstg 55 to +150 o Junction temperature Tj max. 175 oC 706 July 1989SR EE TTA OSB 9415 SERIES High-voltage rectifier stacks : a 3 o7 OSM 9415 SERIES OSS 9415 SERIES N AMER PHILIPS/DISCRETE CSE D EM 6653931 00ee10? & Em _ CHARACTERISTICS (See note 1) i OSB9415 4 6 |. ..J] 34 ] -36A Forward voltage OSM9415 4 6 |...) -34 | -36A Ip = 150 A; Tj =25C Ve < 3.6 54 |. ..}| 306) 324 Vv Reverse avalanche breakdown voltage* > 33 | 4.95 28 | 29.7 kV IR =5 mA; Tj = 25 C V(BR)R < ag|72|...14081432 kv OSS9415 -~3 4 {...] -35 | -36A Forward voltage Ip = 150 A; Tj = 25 C VE < 5.4 724... 63 |} 648 V Reverse avalanche breakdown voitage* = Tes > 4. 6]... : . k InnsmaiT;=75C Vain 2495 | 88 |---| 8 | aaa by Reverse current VM = VRWMmax?
