Substitute Part Grouping Explanation

Substitute parts for the SD175SA30A.T2 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 remain identical:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 30 A
• Voltage - Forward (Vf) (Max) @ If: 490 mV @ 30 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 4 mA @ 30 V
• Capacitance @ Vr, F: 2200 pF @ 5V, 1MHz
• Mounting Type: Surface Mount
• Package / Case: Die
• Operating Temperature - Junction: -55°C ~ 150°C
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

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