Current - Average Rectified (Io): 3 A
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Operating Temperature Range: Compatible with -55°C to 150°C minimum

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 875 mV to 1.3 V @ 3 A
Speed Classification: Fast Recovery ≤ 500ns or Standard Recovery > 500ns
Reverse Recovery Time (trr): 25 ns to 150 ns

Engineering Selection Recommendations

Direct Parametric Equivalent (Recommended Primary Substitute):

RS3DH from Taiwan Semiconductor Corporation is the direct parametric equivalent to RS3D M6G. Both parts share identical electrical specifications (200 V, 3 A, 1.3 V forward voltage, 150 ns reverse recovery time) and package configuration (DO-214AB, SMC). RS3DH is currently in active product status with automotive-grade qualification (AEC-Q101) and is available in Tape & Reel packaging. This part provides the highest level of compatibility for direct replacement.

Active Substitutes with Equivalent Electrical Performance:

CFRC303-G (Comchip Technology), ER3D-TP (Micro Commercial Co), ES3D-13-F (Diodes Incorporated), MURS320-13-F (Diodes Incorporated), MURS320-E3/57T (Vishay), and MURS320-E3/9AT (Vishay) all meet the primary equivalence criteria of 200 V, 3 A, DO-214AB package, and surface mount configuration. These parts are in active product status and RoHS3 compliant. Variations exist in forward voltage (0.875 V to 1.3 V), reverse recovery time (25 ns to 150 ns), and reverse leakage current (5 µA to 10 µA). Selection among these substitutes depends on specific circuit requirements for forward voltage drop and switching speed.

Extended Temperature Range Options:

ER3D-TP, MURS320-13-F, MURS320-E3/57T, and MURS320-E3/9AT offer extended operating temperature ranges (-50°C to 175°C or -65°C to 175°C) compared to the original RS3D M6G specification (-55°C to 150°C). These parts are suitable for applications requiring operation at elevated temperatures.

Not Recommended for New Designs:

S3D-TP (Micro Commercial Co) is marked as "Not For New Designs" and exhibits standard recovery characteristics (> 500ns) rather than fast recovery. This part should not be selected for new circuit implementations.

Package Variant:

ES3DB-13-F is electrically equivalent to ES3D-13-F but uses a DO-214AA (SMB) package instead of DO-214AB (SMC). This part is suitable only if the circuit board layout accommodates SMB package dimensions.

Higher Current Rating:

CGRC503-G (Comchip Technology) is rated for 5 A average rectified current and is not a direct substitute for the 3 A RS3D M6G. This part is suitable only for applications requiring higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can RS3DH be used as a direct replacement for RS3D M6G?

A: Yes. RS3DH is the direct parametric equivalent with identical voltage rating (200 V), current rating (3 A), forward voltage (1.3 V @ 3 A), reverse recovery time (150 ns), and package configuration (DO-214AB, SMC). RS3DH is currently in active production status, making it the recommended primary substitute.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes have reverse recovery time ≤ 500 ns and are designed for high-frequency switching applications. Standard recovery diodes have reverse recovery time > 500 ns and are suitable for lower-frequency rectification. The RS3D M6G specifies fast recovery characteristics. Substitutes with standard recovery (such as S3D-TP) may exhibit different switching behavior in high-frequency circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this document are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original RS3D M6G specifications.

Q: Can ES3DB-13-F be used if the circuit board is designed for DO-214AB (SMC) package?

A: No. ES3DB-13-F uses a DO-214AA (SMB) package, which has different physical dimensions and pin spacing than DO-214AB (SMC). Circuit board layout modifications would be required. Use ES3D-13-F instead, which maintains the DO-214AB (SMC) package configuration.

Q: What is the significance of reverse leakage current differences between substitute parts?

A: Reverse leakage current (Ir) ranges from 5 µA to 10 µA across the substitute parts. Lower leakage current (5 µA) provides better performance in high-impedance circuits and reduces power dissipation. Higher leakage current (10 µA) is acceptable for most general-purpose rectification applications. Selection depends on circuit sensitivity to leakage current.

Q: Which substitute offers the lowest forward voltage drop?

A: ES3D-13-F and MURS320-13-F offer the lowest forward voltage at 0.9 V and 0.875 V respectively (compared to 1.3 V for RS3D M6G). Lower forward voltage reduces power dissipation and heat generation, making these parts suitable for high-current or efficiency-critical applications.

Q: Are automotive-qualified versions available?

A: Yes. RS3DH carries AEC-Q101 automotive qualification. This part is suitable for automotive and industrial applications requiring formal qualification documentation.

Q: What is the difference between cut tape and tape & reel packaging?

A: Cut Tape (CT) packaging is supplied in individual strips suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging is supplied on continuous reels for automated pick-and-place assembly equipment. Both packaging formats contain identical components; selection depends on assembly process requirements.

Q: Can parts with extended temperature ranges (-65°C to 175°C) be used in applications rated for -55°C to 150°C?

A: Yes. Extended temperature range parts (MURS320 series, ER3D-TP) are backward compatible with applications specified for narrower temperature ranges. The extended range provides additional design margin and flexibility for future applications.

Q: Is CGRC503-G a suitable substitute for higher-current applications?

A: CGRC503-G is rated for 5 A average rectified current compared to 3 A for RS3D M6G. This part is suitable only for applications requiring the higher current capacity. It is not a substitute for 3 A circuits, as it represents a different product category.
