T40HFL, T70HFL, T85HFL Series

Fast Recovery Diodes

(T-Modules), 40 A/70 A/85 A

Vishay Semiconductors

Note

(1) Tested on LEM 300 A diodemeter tester

Note

(1) A mounting compound is recommended and the torque should be rechecked after a period of about 3 hours to allow for the spread of

the compound

Note

• The table above shows the increment of thermal resistance RthJC when devices operate at different conduction angles than DC
