SSL34 V7G Schottky Diode Equivalent & Substitute Parts

Part Overview

The SSL34 V7G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 40 V DC reverse voltage and 3 A average rectified current in a DO-214AB surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing production and repair applications. Substitute parts must maintain identical electrical ratings and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSL34 V7G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 3 A
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 40 V

Mechanical Equivalence Requirements:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance Equivalence Requirements:

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

Parts meeting all three categories are classified as direct substitutes. The SSL34 (Tape & Reel packaging variant) and SS34-E3/9AT (Vishay equivalent) satisfy these criteria and are suitable for direct replacement in applications requiring the SSL34 V7G.

Parameter Comparison

Engineering Selection Recommendations

SSL34 (Taiwan Semiconductor Corporation): This part is the direct equivalent to SSL34 V7G, differing only in packaging format (Tape & Reel versus the original packaging specification). The SSL34 maintains identical electrical and mechanical specifications with active product status and ROHS3 compliance. This substitute is preferred for applications requiring the same manufacturer source.

SS34-E3/9AT (Vishay General Semiconductor - Diodes Division): This part provides cross-manufacturer equivalence with identical electrical ratings, package type, and compliance certifications. The SS34-E3/9AT is manufactured by Vishay and carries active product status. Selection of this substitute is appropriate when Taiwan Semiconductor Corporation sourcing is unavailable or when multi-source qualification is required.

Both substitutes are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with standard surface mount assembly processes and long-term storage without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can SSL34 V7G be replaced with SSL34 in production? A: Yes. The SSL34 is electrically and mechanically identical to SSL34 V7G. The difference is packaging format (Tape & Reel). Both parts meet the same electrical specifications: 40 V, 3 A, Schottky technology, DO-214AB package, and ROHS3 compliance.

Q: What is the difference between SSL34 and SS34-E3/9AT? A: Both parts are functionally equivalent with identical electrical ratings (40 V, 3 A, Schottky, Fast Recovery ≤ 500ns). The primary difference is manufacturer: SSL34 is from Taiwan Semiconductor Corporation, while SS34-E3/9AT is from Vishay General Semiconductor - Diodes Division. Both are ROHS3 compliant and use the DO-214AB package.

Q: Are these substitutes suitable for high-temperature applications? A: Yes. All three parts (SSL34 V7G, SSL34, and SS34-E3/9AT) operate across the same junction temperature range of -55°C to 125°C, making them suitable for equivalent thermal environments.

Q: Does packaging format affect electrical performance? A: No. The SSL34 V7G and SSL34 differ only in packaging format (bulk versus Tape & Reel). Electrical performance, package type (DO-214AB), and mounting method (Surface Mount) remain identical.

Q: Are these parts suitable for automated assembly? A: Yes. All substitute parts are surface mount components in DO-214AB package with MSL 1 (Unlimited) rating, compatible with standard pick-and-place and reflow soldering processes without moisture bake-out requirements.

Q: What compliance certifications apply to these substitutes? A: All parts are ROHS3 compliant and REACH unaffected. Both SSL34 and SS34-E3/9AT carry identical compliance status to the original SSL34 V7G.
