VS-HFA70EA120 www.vishay.com Vishay Semiconductors HEXFRED® Ultrafast Soft Recovery Diode, 70 A FEATURES • Fast recovery time characteristic • Electrically isolated base plate • Antiparallel diodes • Large creepage distance between terminal • Simplified mechanical designs, rapid assembly • Designed and qualified for industrial level SOT-227 • UL approved file E78996 • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 DESCRIPTION / APPLICATIONS PRODUCT SUMMARY VR 1200 V VF (typical) 2.2 V trr (typical) 48 ns IF(DC) at TC, per module 70 A at 121 °C Package SOT-227 This SOT-227 modules with HEXFRED® rectifier are in antiparallel configuration. The antiparallel configuration is used for simple series rectifier and high voltage application. The semiconductor in the SOT-227 package is isolated from the copper base plate, allowing for common heatsinks and compact assemblies to be built. These modules are intended for general applications such as HV power supplies, electronic welders, motor control and inverters.
