Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 3 A maximum
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AB, SMC (surface mount)
• Operating Temperature - Junction: -55°C to 150°C minimum range
• Technology: Schottky
• RoHS Status: ROHS3 Compliant

Substitution Categories:

Direct Manufacturer Equivalent: SS320 (Taiwan Semiconductor Corporation) — Identical electrical specifications and package, active product status with full inventory availability.

Parametric Equivalent: SS320C-HF (Comchip Technology) — Meets all primary electrical and mechanical parameters with identical voltage, current, and package specifications. Reverse leakage current and capacitance values differ but remain within acceptable operating ranges for this device category.

Parameter Comparison

Engineering Selection Recommendations

SS320 (Direct Manufacturer Equivalent): This part is the primary substitute for the discontinued SS320 V7G. Manufactured by Taiwan Semiconductor Corporation, it provides identical electrical specifications and package configuration. The part maintains active product status with substantial inventory availability (300,200 pieces), ensuring supply chain continuity. ROHS3 compliance and MSL 1 rating confirm environmental and handling compatibility with the original part.

SS320C-HF (Parametric Equivalent): This Comchip Technology part qualifies as a secondary substitute, meeting all critical electrical parameters including voltage rating, current capacity, forward voltage, and switching speed. The reverse leakage current specification of 300 µA at 200 V exceeds the original 100 µA specification but remains within acceptable limits for Schottky diode applications. Capacitance specification (350 pF @ 4V, 1MHz) is provided for this part. ROHS3 compliance and MSL 1 rating confirm regulatory and handling compatibility. Active product status with 1,116 pieces in inventory supports production requirements.

Both substitute parts are surface mount devices in DO-214AB packaging, compatible with existing PCB layouts and assembly processes. Selection between direct and parametric equivalents depends on supply availability, lead time requirements, and application-specific leakage current tolerance.

Frequently Asked Questions (FAQ)

Q: Can SS320 directly replace SS320 V7G in production?

A: Yes. The SS320 is manufactured by the same supplier (Taiwan Semiconductor Corporation) with identical electrical specifications and package configuration. It is the direct equivalent for the discontinued SS320 V7G.

Q: What are the differences between SS320 and SS320C-HF?

A: Both parts meet the core electrical requirements (200 V, 3 A, 950 mV forward voltage, fast recovery switching). The SS320C-HF has a higher reverse leakage current specification (300 µA versus 100 µA at 200 V) and includes a capacitance specification (350 pF @ 4V, 1MHz). Both are ROHS3 compliant with MSL 1 rating.

Q: Are the substitute parts compatible with existing PCB designs?

A: Yes. Both SS320 and SS320C-HF use the DO-214AB (SMC) surface mount package, identical to the original SS320 V7G. No PCB layout modifications are required.

Q: What is the operating temperature range for substitute parts?

A: Both substitute parts operate across the junction temperature range of -55°C to 150°C, matching the original part specification.

Q: Do the substitute parts meet environmental compliance requirements?

A: Yes. Both SS320 and SS320C-HF are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming compliance with environmental and handling standards.

Q: Which substitute part should be selected for new designs?

A: The SS320 is recommended as the primary choice due to identical specifications and manufacturer continuity. The SS320C-HF serves as an alternative when supply constraints require a secondary source.

Q: Is the higher reverse leakage current of SS320C-HF acceptable?

A: The SS320C-HF reverse leakage current of 300 µA at 200 V is within acceptable limits for Schottky diode applications. Application-specific leakage current tolerance must be evaluated during circuit design validation.
