PRODUCT SUMMARY
IF(AV) VR IRM
2 x 7.5 A 35 V/45 V 15 mA at 125 °C
FEATURES • 150 °C TJ operation • Center tap TO-220 package • Low forward voltage drop • High frequency operation • High purity, high temperature epoxy
encapsulation for enhanced mechanical strength and moisture resistance • Guard ring for enhanced ruggedness and long term reliability • Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C • Halogen-free according to IEC 61249-2-21 definition • Compliant to RoHS directive 2002/95/EC • AEC-Q101 qualified
DESCRIPTION The VS-MBR(B)15... center tap Schottky rectifier has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
