Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD175SA30A.T1 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:

• 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

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The SD175SA30B.T meets all specified electrical and mechanical requirements and is therefore a valid substitute for the SD175SA30A.T1.
