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.
