T70HF40 Datasheet | International Rectifier

Features Electrically isolated base plate Types up to 1200 V RRM 3500 V RMS isolating voltage Simplified mechanical designs, rapid assembly High surge capability Large creepage distances UL E78996 approved T-Modules 40 A 70 A 85 A 110 A Description These series of T-modules use standard recovery power rectifier diodes. The semiconductors are electrically isolated from the metal base, allowing mon heatsink and pact assembly to be built. Applications include power supplies, battery charges, welders, motor controls and general industrial current rectification.
