SS310H Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS310H is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100V DC reverse voltage and 3A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for fast recovery applications requiring switching speeds of 500ns or less at currents exceeding 200mA. The SS310H holds automotive-grade qualification under AEC-Q101 and maintains full RoHS3 compliance. Equivalent substitute parts are identified when manufacturers discontinue production, inventory becomes unavailable, or supply chain optimization requires alternative sourcing from qualified manufacturers offering identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the SS310H are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires exact matching of the following parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 100 V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C ~ 150°C
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Only components meeting all these criteria are classified as direct parametric equivalents. Substitution is valid when the alternative part maintains identical form factor, thermal performance, and regulatory compliance.
