300HF-L

      The 300HF-L series(Vishay High Power Products) possess the chracterastics of very low Vf, RoHS compliant, high surge capability, Stud cathode and stud anode version, popular series for rough service, diffused glass passivated die, and which are designed and qualified for industrial level. The series are usually used as Power supplies, Welders, Motor controls, General industrial current rectification, Battery charges.
      In the aspects of major parameters for 300HF-L series are got, If(av)=300A/120°C(Tc), IFSM(50Hz/60Hz)=5700 A/ 5900 A, I2t(50Hz/60Hz)=160 kA2s/148 kA2s, VRRM(Range)= 400/600 V, TJ =40 to 180 °C. For 300HF, VRRM, MAXIMUM REPETITIVE PEAK REVERSE VOLTAGE(VOLTAGE CODE=40/60)=400V/600V, VRSM, MAXIMUM NON-REPETITIVE PEAK REVERSE VOLTAGE=500V/700V, (IRRM MAXIMUM AT TJ = 180 °C) =10mA. IF(AV)(Maximum average forward current at case temperature, @ 180° conduction, half sine wave)=300A/120°C, I2t(Maximum I2t for fusing, @ t = 0.1 to 10 ms, no voltage reapplied)=1600kA2s, VF(TO)(Maximum value of threshold voltage, @ TJ = 180 °C)=0.70V, rf1(Maximum value of forward slope resistance)=0.40 m, VFM(Maximum forward voltage drop)=1.14V, TJ, TStg(Maximum junction operating and storage temperature range)= 40 to 180 °C, RthJC(Maximum thermal resistance, junction to case, @ DC operation)= 0.17K/W, RthCS(Maximum thermal resistance, case to heatsink, @ Mounting surface, smooth, flat and greased)=0.08 K/W, Maximum allowed mounting torque+ 0 TO 20 %(Not lubricated threads/ubricated threads)=37/28N ` m, Approximate weight=250g, Case style(@ See dimensions - link at the end of datasheet)=DO-205AB (DO-9).
