Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS35 V6G is determined by strict electrical and mechanical parameter matching within the Schottky diode rectifier category. The critical parameters governing substitution are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Technology: Schottky (fast recovery characteristics)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Package / Case: DO-214AB (SMC) surface mount configuration
• Mounting Type: Surface Mount

Environmental & Compliance Parameters:

• Operating Temperature - Junction: -55°C to 150°C minimum range
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting or exceeding these parameters across all categories are classified as direct substitutes. The SS35 (active product from Taiwan Semiconductor Corporation) and HSM350J/TR13 (Microchip Technology) satisfy all electrical and mechanical requirements and are identified as equivalent alternatives.

Engineering Selection Recommendations

Primary Substitute: SS35 (Taiwan Semiconductor Corporation)

The SS35 is the direct equivalent to the SS35 V6G, manufactured by the same supplier with identical electrical specifications and package configuration. This part is currently in active production status with 10,140 units in stock. Both parts maintain RoHS3 compliance and identical operating temperature ranges. The SS35 is the preferred substitute for direct replacement in applications where the original SS35 V6G is no longer available.

Secondary Substitute: HSM350J/TR13 (Microchip Technology)

The HSM350J/TR13 meets all critical electrical and mechanical parameters with equivalent 50 V reverse voltage, 3 A rectified current, and DO-214AB package configuration. This part offers superior reverse leakage characteristics (100 µA versus 500 µA) and an extended operating temperature range (-55°C to 175°C). However, this part is RoHS non-compliant, which may restrict its use in applications subject to RoHS3 regulatory requirements. The HSM350J/TR13 is supplied in Tape & Reel packaging format with 813 units currently in stock.

Selection between these substitutes depends on regulatory compliance requirements and thermal operating envelope specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the SS35 directly replace the SS35 V6G without circuit modification?

A: Yes. The SS35 is electrically and mechanically identical to the SS35 V6G. Both parts share the same 50 V reverse voltage rating, 3 A rectified current capacity, Schottky technology, fast recovery speed characteristics, and DO-214AB surface mount package. Direct substitution is supported without circuit redesign.

Q: What is the primary difference between the SS35 and HSM350J/TR13?

A: The HSM350J/TR13 exhibits lower reverse leakage current (100 µA versus 500 µA at 50 V) and a higher maximum junction temperature rating (175°C versus 150°C). The HSM350J/TR13 is supplied in Tape & Reel packaging, whereas the SS35 V6G specification does not specify packaging format. The HSM350J/TR13 is RoHS non-compliant, while the SS35 maintains RoHS3 compliance.

Q: Are there packaging differences between substitute options?

A: Both the SS35 and HSM350J/TR13 utilize the DO-214AB (SMC) surface mount package, ensuring mechanical and footprint compatibility. The HSM350J/TR13 is supplied in Tape & Reel (TR) format for automated assembly, while the SS35 packaging format is not specified in the provided data. Both parts are suitable for surface mount assembly processes.

Q: Which substitute should be selected for RoHS-regulated applications?

A: The SS35 is the appropriate selection for applications subject to RoHS3 compliance requirements. The SS35 maintains RoHS3 compliant status, whereas the HSM350J/TR13 is RoHS non-compliant and is unsuitable for regulated environments.

Q: Does the HSM350J/TR13 lower forward voltage affect circuit performance?

A: The HSM350J/TR13 exhibits a lower maximum forward voltage (620 mV at 3 A) compared to the SS35 (750 mV at 3 A). In rectification applications, lower forward voltage reduces power dissipation and heat generation. Circuit performance impact depends on the specific application topology and thermal design. Both parts operate within the Schottky diode fast recovery classification and are functionally compatible.

Q: What is the inventory status of available substitutes?

A: The SS35 has 10,140 units in stock and is in active production. The HSM350J/TR13 has 813 units in stock and is in active production. The original SS35 V6G is discontinued at DiGi Electronics with 1,000 units reported in stock.
