electrically isolated from elements for simple heatsink construction. Wide voltage rating
up to 1,600V is available for various input voltage.
Isolated mounting base
Two elements in a packing for simple
single and three phase bridge
connections
Highly reliable glass passivated chips
High surge current capability
Applications
Various rectifiers, Bettery chargers, DC motor drives
Maximum Ratings
Tj25 unless otherwise specified
