FEATURES
¨ Plastic package has Underwriters Laboratory
Flammability Classification 94V-0
¨ High temperature stability due to unique oxide
passivation
¨ Patented Passivated Anisotropic Rectifier
(PAR) construction
¨ Integrally molded heatsink provides
a very low thermal resistance for
maximum heat dissipation
¨ Low leakage current at TJ=175¡C
¨ Low forward voltage drop
¨ Ideally suited for alternator rectification and load dump
protection
¨ High temperature soldering guaranteed:
260¡C for 10 seconds at terminals
