Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Maximum DC Reverse Voltage (Vr): ≥ 45 V
Average Rectified Current per Diode (Io): ≥ 80A
Forward Voltage Drop (Vf) at rated If
Reverse Leakage Current at Vr
Speed: Fast Recovery =< 500ns, > 200mA (Io)
Operating Temperature Range: -55°C ~ 150°C
Mounting Type: Chassis Mount
Package / Case: TO-249AB
Moisture Sensitivity Level: 1 (Unlimited)

Only components meeting these parameters are considered valid substitutes.
