Preliminary Data
Features
Glass passivated silicon chips
Low thermal impedance through
use of direct copper bonded
aluminum substrate (DCB) base
plate
Blocking voltage up to 1800 V
Suitable for PCB mounting and
wave soldering
For applications with high
vibrations we recommend to
fasten the bridge to the pcb with
4 selftapping screws
UL recognition applied for
Typical Applications
Three phase rectifiers for power
supplies
Input rectifiers for variable
frequency drives
Rectifiers for DC motor field
supplies
Battery charger rectifiers
