HS3A M6G Equivalent & Substitute Parts

Part Overview

The HS3A M6G 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 DO-214AB (SMC) surface mount package. This device is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The HS3A M6G operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 50 ns. RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) support deployment in industrial and commercial applications.

Substitute Part Grouping Explanation

Substitute parts for the HS3A M6G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share identical electrical specifications and package form factor (DO-214AB SMC). These parts are direct functional replacements with no derating or circuit modification required:

Voltage - DC Reverse (Vr) (Max): 50 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 1 V @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 50 ns
Package / Case: DO-214AB, SMC

Similar Parts maintain the same voltage and current ratings but exhibit variations in secondary parameters such as forward voltage, reverse recovery time, or capacitance. These parts are functionally compatible within the same electrical class but require circuit-level verification for timing-sensitive applications.

Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents)

The HS3A manufactured by Taiwan Semiconductor Corporation in Tape & Reel (TR) packaging is the direct parametric equivalent to HS3A M6G. This part maintains identical electrical specifications and package form factor while offering active product status, ensuring long-term availability and supply chain continuity.

CURC301-G manufactured by Comchip Technology is a parametric equivalent offering identical voltage, current, forward voltage, and recovery time specifications. This part is actively produced and available in Tape & Reel packaging, providing a reliable alternative source for the HS3A M6G electrical function.

Secondary Substitutes (Similar Parts with Active Status)

ES3A-13-F manufactured by Diodes Incorporated provides equivalent voltage and current ratings with improved forward voltage characteristics (0.9 V vs. 1 V) and faster reverse recovery time (25 ns vs. 50 ns). This part is actively produced and available in Cut Tape and Digi-Reel packaging. The lower forward voltage reduces power dissipation in rectification circuits.

RS3A-13-F and RS3A-E3/57T manufactured by Vishay General Semiconductor maintain equivalent voltage and current ratings with extended reverse recovery time (150 ns vs. 50 ns). These parts are actively produced and suitable for applications where slower recovery characteristics are acceptable or beneficial for EMI reduction.

Packaging Considerations

HS3A M6G is supplied in unspecified packaging. The parametric equivalent HS3A is available in Tape & Reel (TR) packaging. HS3A R7G is available in Cut Tape (CT) packaging. HS3A V7G packaging is unspecified. Selection of packaging format depends on assembly process requirements and volume considerations.

ES3AB-13-F is available in DO-214AA (SMB) package, which differs from the DO-214AB (SMC) package of the main part. SMB package substitution requires PCB layout modification and is not recommended as a direct replacement without design review.

Compliance and Regulatory Status

All recommended substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity level, ensuring compatibility with existing procurement and manufacturing specifications.

Frequently Asked Questions (FAQ)

Q: Can HS3A M6G be directly replaced with HS3A in Tape & Reel packaging?

A: Yes. The HS3A in Tape & Reel packaging is a parametric equivalent with identical electrical specifications (50 V, 3 A, 1 V forward voltage, 50 ns recovery time) and the same DO-214AB SMC package form factor. The primary difference is packaging format and active product status.

Q: What is the difference between HS3A M6G and CURC301-G?

A: Both parts share identical electrical specifications: 50 V reverse voltage, 3 A current rating, 1 V forward voltage at 3 A, and 50 ns reverse recovery time. CURC301-G is manufactured by Comchip Technology and maintains active product status, whereas HS3A M6G is discontinued. Both use DO-214AB SMC packaging.

Q: Why does ES3A-13-F show lower forward voltage (0.9 V) compared to HS3A M6G (1 V)?

A: Forward voltage variation is a normal characteristic difference between manufacturers and device families. ES3A-13-F exhibits lower forward voltage, which reduces power dissipation during rectification. This is a beneficial characteristic for thermal management but requires verification that the circuit design does not depend on specific forward voltage thresholds.

Q: Can ES3AB-13-F replace HS3A M6G?

A: ES3AB-13-F shares identical electrical ratings (50 V, 3 A) and fast recovery characteristics but uses DO-214AA (SMB) package instead of DO-214AB (SMC) package. SMB and SMC packages have different footprints and land patterns. Direct substitution requires PCB redesign and is not recommended without design review.

Q: What is the significance of reverse recovery time (trr) differences between substitute parts?

A: Reverse recovery time affects switching speed and EMI characteristics. HS3A M6G has 50 ns recovery time. ES3A-13-F has 25 ns (faster), while RS3A-13-F has 150 ns (slower). Faster recovery reduces switching losses and EMI but may increase switching noise. Slower recovery reduces EMI but increases switching losses. Selection depends on circuit topology and EMI requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts listed in this document maintain RoHS3 compliance and REACH unaffected status, ensuring compatibility with environmental and regulatory requirements.

Q: Why is CGRC501-G listed as a similar part rather than a direct substitute?

A: CGRC501-G is rated for 5 A current versus 3 A for HS3A M6G. While the 50 V voltage rating is identical, the higher current rating and different recovery speed classification (standard recovery >500ns vs. fast recovery ≤500ns) place it in a different functional category. CGRC501-G is suitable for applications requiring higher current capacity but not as a direct replacement for 3 A circuits.

Q: What packaging options are available for HS3A equivalents?

A: HS3A parametric equivalents are available in Tape & Reel (TR) and Cut Tape (CT) packaging formats. Selection depends on assembly process requirements. Tape & Reel is standard for high-volume automated assembly. Cut Tape is suitable for lower volumes or manual assembly processes.
