Equivalent & Substitute Parts for S5A-M3/57T

Part Overview

The S5A-M3/57T is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 50 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as an Active product with standard recovery characteristics and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. The S5A-M3/57T has limited current inventory (1029 Pcs), making alternative sources valuable for production continuity and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S5A-M3/57T are qualified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 5 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

All identified substitute parts maintain these electrical ratings and mechanical specifications. Secondary parameters such as reverse recovery time and capacitance may vary within acceptable ranges for general-purpose rectifier applications without affecting functional compatibility in standard circuit implementations.

Engineering Selection Recommendations

S5A-E3/57T (Vishay General Semiconductor - Diodes Division)

The S5A-E3/57T is the primary substitute for the S5A-M3/57T. Both parts are manufactured by Vishay and maintain identical electrical specifications across all critical parameters. The S5A-E3/57T carries Active product status with significantly higher inventory availability (30100 Pcs), providing superior supply chain reliability. Both parts are ROHS3 compliant and carry identical compliance certifications (REACH Unaffected, EAR99, HTSUS 8541.10.0080). This substitute is suitable for direct replacement in all applications where the S5A-M3/57T is specified.

S5A V7G (Taiwan Semiconductor Corporation)

The S5A V7G is a parametric equivalent manufactured by Taiwan Semiconductor Corporation. This part maintains all critical electrical ratings (50 V, 5 A, 1.15 V forward voltage) and identical package specifications (DO-214AB, SMC). The S5A V7G exhibits a faster reverse recovery time (1.5 µs versus 2.5 µs) and higher capacitance (60 pF versus 40 pF), which may provide performance benefits in specific circuit topologies. However, this part carries a Discontinued at DiGi Electronics status, limiting long-term availability. The S5A V7G is ROHS3 compliant with equivalent regulatory certifications. Selection of this substitute should account for its discontinued status and reduced inventory (2533 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the S5A-E3/57T be used as a direct replacement for the S5A-M3/57T?

A: Yes. The S5A-E3/57T is electrically and mechanically equivalent to the S5A-M3/57T across all critical parameters, including voltage rating, current rating, forward voltage, package type, and operating temperature range. Both parts are manufactured by Vishay and carry identical compliance certifications.

Q: What is the difference between the S5A-M3/57T and S5A V7G?

A: The S5A V7G differs in reverse recovery time (1.5 µs versus 2.5 µs) and capacitance (60 pF versus 40 pF). All other electrical specifications and the package type (DO-214AB, SMC) are identical. The S5A V7G is manufactured by Taiwan Semiconductor Corporation and carries a Discontinued status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The S5A-M3/57T, S5A-E3/57T, and S5A V7G are all ROHS3 compliant. All three parts carry REACH Unaffected status and identical ECCN and HTSUS classifications.

Q: Does the faster reverse recovery time of the S5A V7G affect circuit compatibility?

A: The S5A V7G reverse recovery time of 1.5 µs is faster than the 2.5 µs specification of the S5A-M3/57T. In general-purpose rectifier applications, this difference does not affect functional compatibility. Circuit-specific performance may vary depending on switching frequency and load characteristics.

Q: What is the moisture sensitivity level for these diodes?

A: All three parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in surface mount assembly?

A: Yes. All three parts use identical surface mount packaging (DO-214AB, SMC) and are suitable for standard pick-and-place assembly processes without modification to board design or assembly procedures.

Q: Which substitute part should be selected for new designs?

A: The S5A-E3/57T is recommended for new designs due to its Active product status, high inventory availability, and identical specifications to the S5A-M3/57T. The S5A V7G should be avoided for new designs due to its Discontinued status.
