HS5A V6G Equivalent & Substitute Parts

Part Overview

The HS5A V6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The HS5A V6G features fast recovery characteristics with a reverse recovery time of 50 nanoseconds, making it suitable for applications requiring rapid switching performance. The device operates across a junction temperature range of -55°C to 150°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS5A V6G is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Voltage - DC Reverse (Vr) Maximum: 50 V
• Current - Average Rectified (Io): 5 A
• Package / Case: DO-214AB, SMC
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Speed Classification: Fast Recovery characteristics (≤ 500ns)
• Reverse Recovery Time (trr): 50 ns
• Reverse Leakage Current: 10 µA @ 50 V
• Capacitance: 80 pF @ 4V, 1MHz

The HS5A V6G (discontinued) has a direct equivalent in the HS5A manufactured by Taiwan Semiconductor Corporation, which maintains identical electrical specifications and packaging while remaining in active product status. The S3AHE3_A/H from Vishay General Semiconductor represents a similar but not fully equivalent substitute, as it operates at reduced current capacity (3 A versus 5 A) and exhibits different speed characteristics (standard recovery versus fast recovery).

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred):

The HS5A manufactured by Taiwan Semiconductor Corporation is the direct equivalent to the discontinued HS5A V6G. This part maintains identical electrical specifications, package configuration, and compliance certifications. The HS5A is currently in active product status with 931 pieces available in inventory. Selection of this part eliminates any performance or compatibility concerns and requires no circuit redesign.

Alternative Substitute (Limited Application):

The S3AHE3_A/H from Vishay General Semiconductor may be considered only in applications where the reduced current capacity (3 A versus 5 A) and slower recovery characteristics (2.5 µs versus 50 ns) are acceptable. This part carries automotive-grade qualification (AEC-Q101) and may be preferred in automotive applications requiring such certification. However, this substitution introduces functional differences and is not recommended for designs requiring the full 5 A current rating or fast recovery performance of the original HS5A V6G.

Both substitute options maintain identical reverse voltage ratings (50 V), package form factor (DO-214AB, SMC), operating temperature range (-55°C to 150°C), and regulatory compliance (ROHS3, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can the HS5A directly replace the discontinued HS5A V6G?

A: Yes. The HS5A is the direct equivalent, maintaining identical voltage rating (50 V), current capacity (5 A), speed characteristics (fast recovery, 50 ns reverse recovery time), package type (DO-214AB, SMC), and compliance status (ROHS3). No circuit modifications are required.

Q: What is the difference between the HS5A and S3AHE3_A/H?

A: The primary differences are current capacity and recovery speed. The HS5A supports 5 A average rectified current with 50 ns reverse recovery time (fast recovery). The S3AHE3_A/H supports only 3 A with 2.5 µs reverse recovery time (standard recovery). Both maintain the same 50 V reverse voltage rating and DO-214AB package. The S3AHE3_A/H includes automotive qualification (AEC-Q101).

Q: Can I use the S3AHE3_A/H in a design originally specified for HS5A V6G?

A: Only if the application circuit can tolerate reduced current capacity (3 A maximum versus 5 A) and slower switching response (2.5 µs versus 50 ns). Applications requiring the full 5 A rating or fast recovery performance must use the HS5A equivalent.

Q: Are there packaging differences between these parts?

A: No. All three parts (HS5A V6G, HS5A, and S3AHE3_A/H) use the DO-214AB (SMC) surface mount package. The HS5A is available in Tape & Reel (TR) packaging, while the original HS5A V6G packaging format is not specified in available data.

Q: Do these parts have the same compliance certifications?

A: Yes, all three parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). The S3AHE3_A/H additionally carries automotive-grade qualification (AEC-Q101), which is not applicable to the Taiwan Semiconductor Corporation parts.

Q: What is the reverse leakage current specification?

A: All three parts specify 10 µA maximum reverse leakage current at 50 V reverse bias, indicating equivalent leakage performance across the product range.
