50PF80 Datasheet

Std. Recovery Diode in a DO-5 Package


Features, Applications

High surge current capability Designed for a wide range of applications Stud cathode and stud anode version Leaded version available/ wire version available Low thermal resistance UL approval pending

Typical Applications
Battery charges Converters Power supplies Machine tool controls Welding
Voltage Type number Code VRRM, maximum repetitive peak reverse voltage V
VRSM, maximum nonrepetitive peak reverse voltage V

I F(AV) Max. average forward current @ Case temperature Max. peak, one-cycle forward, non-repetitive surge current

V No voltage reapplied 100% VRRM reapplied No voltage reapplied 100% VRRM reapplied Sinusoidal half wave, Initial 150�C 180� conduction, half sine wave

Maximum I2t for fusing Low level value of threshold voltage Low level value of forward slope resistance Max. forward voltage drop

10ms, no voltage reapplied (16.7% x IF(AV) IF(AV)), = TJ max. (16.7% x IF(AV) IF(AV)), = TJ max. Ipk= = 400�s rectangular wave

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 K/W Nm lbf in Nm lbf in g (oz) See Outline Table Tighting on Hexagon (2) Mounting surface, smooth, flat and greased Tighting on nut (1)

(1) As general recommendation we suggest to tight on Hexagon and not on nut (2) Torque must be appliable only to Hexagon and not to plastic structure

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