Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) (per Diode): 160 A
• Voltage - Forward (Vf) (Max) @ If: 1.17 V @ 160 A
• Current - Reverse Leakage @ Vr: 1.5 mA @ 80 V
• Technology: Schottky

Mechanical Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-249AA
• Mounting Type: Chassis Mount

Environmental & Compliance Parameters:

• Operating Temperature - Junction: -55°C ~ 175°C
• RoHS Status: ROHS3 Compliant

A substitute part must match all electrical specifications, maintain identical diode configuration and pinout, utilize the same package type, and satisfy equivalent environmental and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations
