S5D M6G Equivalent & Substitute Parts

Part Overview

The S5D M6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 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 production and repair applications. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts offer functional alternatives with minor parameter variations within acceptable operating ranges.

Substitute Part Grouping Explanation

Substitution of the S5D M6G is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 200 V to ensure equivalent circuit protection and reliability.

Current Rating: All substitute parts must support a minimum average rectified current of 5 A to handle the same load conditions.

Package Type: All substitute parts must use the DO-214AB (SMC) surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts.

Recovery Characteristics: Standard recovery diodes with reverse recovery time greater than 500 ns are functionally equivalent for general-purpose rectification applications.

Temperature Range: Operating temperature range must encompass the application requirements; the S5D M6G operates from -55°C to 150°C.

Compliance: All substitute parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels (MSL 1).

Substitute parts are grouped into two categories:

Direct Equivalents (5 A, 200 V, DO-214AB): Parts meeting all electrical and mechanical specifications with identical current and voltage ratings.

Similar Parts (3 A, 200 V, DO-214AB): Parts with reduced current rating (3 A instead of 5 A) suitable only for applications with lower current requirements.

Engineering Selection Recommendations

Primary Equivalent Selection:

S5DH is the recommended direct equivalent for S5D M6G replacement. This part is manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (200 V, 5 A, 1.15 V forward voltage, 1.5 µs recovery time) and is currently in active production status. S5DH is available in Tape & Reel packaging with 3913 units in stock, providing supply continuity for production applications.

Secondary Equivalent Options:

S5DC-13-F (Diodes Incorporated) and CGRC503-G (Comchip Technology) are functionally equivalent alternatives, both rated 200 V, 5 A in DO-214AB packages with active product status. S5DC-13-F offers extended operating temperature range (-65°C to 150°C) and is available in high volume (7971 units). CGRC503-G provides automotive-grade qualification (AEC-Q101) for applications requiring automotive compliance.

Alternative with Minor Parameter Variation:

S5DL-TP (Micro Commercial Co) maintains 200 V, 5 A specifications but exhibits slightly elevated forward voltage (1.2 V @ 5 A versus 1.15 V) and higher capacitance (100 pF versus 60 pF). This part carries "Not For New Designs" status and should be used only for legacy system maintenance where supply constraints exist.

Reduced Current Alternatives (3 A Rating):

Parts including ER3D-TP, ES3D-13-F, MURS320-13-F, and MURS320-E3/57T are rated for 3 A average rectified current and are suitable only for applications with maximum current requirements not exceeding 3 A. These parts feature fast recovery characteristics (25-35 ns) compared to the standard recovery profile of the S5D M6G.

Package Compatibility Note:

ES3DB-13-F uses DO-214AA (SMB) package instead of DO-214AB (SMC) and requires PCB layout modification. This part is not recommended for direct substitution without board redesign.

Frequently Asked Questions (FAQ)

Q: Can S5DH directly replace S5D M6G without circuit modification?

A: Yes. S5DH is a direct equivalent with identical voltage rating (200 V), current rating (5 A), forward voltage (1.15 V @ 5 A), and recovery time (1.5 µs). Both parts use DO-214AB surface mount packages. No circuit modification is required.

Q: What is the difference between S5DH and S5D V7G?

A: Both parts are electrically identical (200 V, 5 A, 1.15 V forward voltage, 1.5 µs recovery time) and use the same DO-214AB package. The primary difference is packaging format: S5DH is supplied in Tape & Reel, while S5D V7G is supplied in Cut Tape. S5D V7G is discontinued at DiGi Electronics. S5DH is the preferred active alternative.

Q: Can I use a 3 A rated diode (such as ES3D-13-F) in place of the 5 A S5D M6G?

A: Only if your circuit's maximum current requirement does not exceed 3 A. The 3 A parts are not suitable for applications requiring the full 5 A capacity of the original S5D M6G. Using an undersized component in a 5 A application will result in excessive junction temperature and premature failure.

Q: What is the significance of "Standard Recovery" versus "Fast Recovery" in these diodes?

A: The S5D M6G uses standard recovery technology with reverse recovery time of 1.5 µs. Fast recovery diodes (such as ES3D-13-F with 25 ns trr) switch faster but are not required for general-purpose rectification. Standard recovery diodes are appropriate for 50/60 Hz power supply applications and lower frequency circuits.

Q: Is S5DL-TP a suitable replacement for S5D M6G?

A: S5DL-TP maintains the same 200 V, 5 A ratings and DO-214AB package but exhibits higher forward voltage (1.2 V versus 1.15 V) and higher capacitance (100 pF versus 60 pF). This part carries "Not For New Designs" status. Use S5DH or S5DC-13-F as preferred alternatives.

Q: What does "AEC-Q101" qualification on CGRC503-G indicate?

A: AEC-Q101 is an automotive electronics qualification standard. CGRC503-G meets automotive reliability and testing requirements, making it suitable for automotive applications. This qualification is not present on other equivalent parts listed.

Q: Can I substitute ES3DB-13-F (SMB package) for S5D M6G (SMC package)?

A: No. ES3DB-13-F uses DO-214AA (SMB) package while S5D M6G uses DO-214AB (SMC) package. These packages have different physical dimensions and PCB footprints. Substitution requires PCB redesign and is not recommended for direct replacement.

Q: Why is S5D V7G listed as discontinued if it is electrically identical to S5D M6G?

A: Both S5D M6G and S5D V7G are discontinued at DiGi Electronics, indicating end-of-life status at this distributor. S5DH, manufactured by the same company (Taiwan Semiconductor Corporation), is the active production equivalent and is the recommended replacement source.

Q: What packaging options are available for equivalent 5 A, 200 V diodes?

A: S5DH is available in Tape & Reel (TR) format. S5DC-13-F is available in Cut Tape (CT) and Digi-Reel® formats. CGRC503-G is available in Tape & Reel format. Selection depends on production volume requirements and assembly equipment compatibility.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for current manufacturing standards.
