HS3A V6G Equivalent & Substitute Parts

Part Overview

The HS3A V6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 3 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 requirements and production needs. Alternative parts must satisfy the electrical and mechanical specifications required for the application while maintaining compatibility with existing PCB layouts and thermal management strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS3A V6G is determined by strict equivalence or functional compatibility across the following critical parameters:

Direct Equivalent Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Package / Case: DO-214AB, SMC (mechanical and thermal compatibility)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Functional Substitute Criteria:

• Current - Average Rectified (Io): Equal to or greater than 3 A
• Speed Classification: Fast Recovery or Standard Recovery
• Reverse Recovery Time (trr): Specified value (not a limiting factor for substitution)
• Current - Reverse Leakage @ Vr: 10 µA @ 50 V or lower
• Capacitance @ Vr, F: Specified value (not a limiting factor for substitution)

The HS3A (direct equivalent from Taiwan Semiconductor Corporation) maintains identical electrical and mechanical specifications. The S5A-E3/9AT (Vishay General Semiconductor) qualifies as a functional substitute with higher current rating (5 A vs. 3 A) and identical voltage rating, though with different speed classification and recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

HS3A (Direct Equivalent): The HS3A from Taiwan Semiconductor Corporation is the direct equivalent to the HS3A V6G. This part maintains identical electrical specifications, package configuration, and compliance certifications. The HS3A is currently in active product status with 759 pieces available in inventory. Selection of this part eliminates any performance variation and is suitable for direct replacement in existing designs without circuit modification.

S5A-E3/9AT (Functional Substitute): The S5A-E3/9AT from Vishay General Semiconductor qualifies as a functional substitute when higher current capacity is acceptable or required. This part provides 5 A average rectified current versus the 3 A specification of the main part, maintaining the 50 V voltage rating and DO-214AB package compatibility. The S5A-E3/9AT operates within the same temperature range and meets identical compliance requirements (ROHS3, MSL 1). The primary electrical difference is the speed classification: the S5A-E3/9AT is classified as Standard Recovery (>500ns) with a reverse recovery time of 2.5 µs, compared to the Fast Recovery (≤500ns, 50 ns trr) characteristic of the HS3A V6G. This difference affects switching performance in high-frequency applications. The S5A-E3/9AT is currently in active product status with 1129 pieces available in inventory.

Selection Basis:

• Direct replacement requirement: Select HS3A
• Higher current capacity acceptable: Select S5A-E3/9AT
• Compliance and regulatory requirements: All options meet ROHS3 and MSL 1 specifications
• Inventory availability: Both substitute options are in active production with adequate stock

Frequently Asked Questions (FAQ)

Q: Can the HS3A be used as a direct replacement for the HS3A V6G?

A: Yes. The HS3A is the direct equivalent part with identical electrical specifications (50 V, 3 A), package configuration (DO-214AB, SMC), and compliance certifications. No circuit modification is required.

Q: What is the primary difference between the HS3A and the S5A-E3/9AT?

A: The HS3A is rated for 3 A average rectified current with Fast Recovery characteristics (50 ns reverse recovery time). The S5A-E3/9AT is rated for 5 A average rectified current with Standard Recovery characteristics (2.5 µs reverse recovery time). Both maintain the 50 V voltage rating and DO-214AB package.

Q: Can the S5A-E3/9AT replace the HS3A V6G in all applications?

A: The S5A-E3/9AT provides higher current capacity and is mechanically compatible via the DO-214AB package. However, the difference in speed classification (Standard Recovery vs. Fast Recovery) affects switching performance. Applications requiring fast switching or operating at high frequencies may experience different performance characteristics. Applications with current requirements at or below 3 A do not require the higher current rating of the S5A-E3/9AT.

Q: Are all substitute parts RoHS compliant?

A: Yes. The HS3A and S5A-E3/9AT are both ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the HS3A V6G.

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

A: All parts (HS3A V6G, HS3A, and S5A-E3/9AT) operate across a junction temperature range of -55°C to 150°C.

Q: Does the DO-214AB package ensure PCB layout compatibility?

A: Yes. All parts use the DO-214AB (SMC) surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts designed for the HS3A V6G. No footprint modification is required.

Q: What is the reverse leakage current specification?

A: All parts specify 10 µA @ 50 V reverse leakage current, indicating identical leakage performance across the main part and substitutes.

Q: How do the capacitance values differ between parts?

A: The HS3A V6G and HS3A specify 80 pF @ 4V, 1MHz. The S5A-E3/9AT specifies 40 pF @ 4V, 1MHz. Lower capacitance in the S5A-E3/9AT may provide advantages in high-frequency applications by reducing parasitic effects.
