DIODE MODULE
DWF(R)70BB30/40
Power Diode Module
DWF(W)70BB
is designed for three phase half wave rectification,
which has three diodes connected in a three phase bridge configuration. The mounting
base of the module is electrically isolated from semiconductor elements for simple
heatsink construction. Output DC current is 70Amp
（Tc＝106℃）
Repetitive peak
reverse voltage is up to 400V.
