Substitute Part Grouping Explanation

Substitute parts for the STB30150C are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires exact matching of the following parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Voltage - Forward (Vf) (Max) @ If: 1.36 V @ 15 A
• Current - Reverse Leakage @ Vr: 200 µA @ 150 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C ~ 150°C
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as direct parametric equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison
