Vishay High Power Products
Power Rectifier Diodes (T-Modules),
40 A/70 A/85 A/110 A
FEATURES
• Electrically isolated base plate
40 to 110 A
• Types up to 1200 V
• 3500 V
isolating voltage
RMS
• Simplified mechanical designs, rapid assembly
• High surge capability
• Large creepage distances
• UL E78996 approved
• RoHS compliant
• Designed and qualified for industrial level
DESCRIPTION
These series of T-modules use standard recovery power
rectifier diodes. The semiconductors are electrically isolated
from the metal base, allowing common heatsink and
compact assembly to be built.
Applications include power supplies, battery charges,
welders, motor controls and general industrial current
rectification.
