Substitute Part Grouping Explanation

Substitute parts for the SD640CS_S2_00001 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match identically:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 6 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 3 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 40 V
• Operating Temperature - Junction: -55°C ~ 150°C
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
