Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS39 V6G is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 3 A
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 90 V

Mechanical & Environmental Specifications:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance & Certification:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as direct equivalents. The SS39 base part number from Taiwan Semiconductor Corporation satisfies all substitution criteria and is available in active product status with higher inventory levels than the discontinued SS39 V6G variant.

Parameter Comparison

Engineering Selection Recommendations

The SS39 (base part number) from Taiwan Semiconductor Corporation is a direct functional equivalent to the SS39 V6G. Both parts share identical electrical ratings, package specifications, and environmental operating ranges. The substitute part offers the additional advantage of active product status with confirmed inventory availability of 1210 pieces, compared to the discontinued status of the SS39 V6G variant.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), ensuring compatibility with standard surface mount assembly processes and long-term storage requirements. The substitute part is suitable for direct replacement in applications currently specified for the SS39 V6G without circuit redesign or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can the SS39 substitute directly for the SS39 V6G in existing designs?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications (90 V reverse voltage, 3 A average rectified current), switching characteristics (fast recovery ≤ 500ns), and package configuration (DO-214AB, SMC). No circuit modifications are required.

Q: Are there any differences in forward voltage characteristics between these parts?

A: The substitute part (SS39) specifies a maximum forward voltage of 850 mV at 3 A. The main part (SS39 V6G) does not provide forward voltage data in the available documentation. Both parts meet the same reverse voltage and current ratings, and both employ Schottky technology with identical reverse leakage specifications.

Q: What is the significance of the DO-214AB package designation?

A: DO-214AB is a surface mount package standard for small signal and rectifier diodes. Both the main part and substitute use this identical package, ensuring mechanical and electrical compatibility with existing PCB layouts, solder pad geometries, and automated assembly equipment.

Q: Why is the SS39 V6G listed as discontinued?

A: The SS39 V6G variant is discontinued at DiGi Electronics. The base SS39 part number remains in active production status with higher inventory levels, providing continuity of supply for applications requiring these electrical specifications.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the SS39 V6G and SS39 are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (unlimited moisture sensitivity), indicating no special moisture control requirements during storage or assembly.

Q: What is the operating temperature range for these diodes?

A: Both parts operate across a junction temperature range of -55°C to 150°C, suitable for industrial and commercial applications with standard thermal management.
