• Reverse leakage current: 200 µA at 45V
• Recovery speed classification: Fast Recovery ≤ 500ns

Mechanical & Package Equivalence Criteria:

• Mounting type: Through Hole
• Package designation: TO-220-2 Full Pack (ITO-220AC supplier package)

Compliance & Grade Equivalence Criteria:

• Technology: Schottky diode
• Automotive grade qualification
• AEC-Q101 certification
• Operating temperature range: -55°C to 150°C
• RoHS3 compliance

Substitute parts must match all electrical parameters, maintain identical package and mounting specifications, and retain automotive-grade certification to ensure direct circuit compatibility without design modification.
