Features

High surge current capability Designed for a wide range of applications Stud cathode and stud anode version Leaded version available Types to 1600V VRRM

Battery charges Converters Power supplies Machine tool controls
Type number Voltage Code VRRM, maximum repetitive peak reverse voltage V
VRSM, maximum nonrepetitive peak reverse voltage V
(1) Avalanche version only available from VRRM to 1600V.

IF(AV) Max. average forward current @ Case temperature IF(RMS) Max. RMS forward current PR IFSM Maximum non-repetitive peak reverse power Max. peak, one-cycle forward, non-repetitive surge current I 2t Maximum I2t for fusing I2 t Maximum I2 t for fusing x I F(AV)), = TJ max. (16.7% x IF(AV) IF(AV)), = TJ max. x I F(AV)), = TJ max. = 10ms sinusoidal wave

�C A KW 25�C 10�s square pulse, T J max. see note s No voltage reapplied 100% VRRM reapplied No voltage reapplied 100% VRRM reapplied Sinusoidal half wave, Initial = TJ max. 180� conduction, half sine wave

V F(TO)1 Low level value of threshold voltage V F(TO)2 High level value of threshold voltage r
High level value of forward slope resistance
(2) Available only for Avalanche version, all other parameters the same as 70HF.

TJ Tstg RthJC RthCS T Max. junction operating temperature range Max. storage temperature range Max. thermal resistance, junction to case Max. thermal resistance, case to heatsink Max. allowed mounting torque �10%

DC operation Mounting surface, smooth, flat and greased Not lubricated threads

(The following table shows the increment of thermal resistence RthJC when devices operate at different conduction angles than DC)

72 = Isolated lead with silicone sleeve (Red = Reverse polarity) (Blue = Normal polarity) 3 = Standard diode = Avalanche diode

None = Stud Normal Polarity (Cathode to Stud) R = Stud Reverse Polarity (Anode to Stud)

Voltage code: Code 10 = VRRM (See Voltage Ratings table) None = Stud base M = Stud base 1 - (Not available for Avalanche diodes)
