Equivalent & Substitute Parts for S5D-M3/9AT

Part Overview

The S5D-M3/9AT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 200 V DC reverse voltage with a 5 A average rectified current rating and is packaged in the DO-214AB (SMC) form factor. The device is classified as Active product status and is ROHS3 compliant. Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or manufacturing discontinuation while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S5D-M3/9AT is determined by strict equivalence across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 200 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
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain identical electrical performance characteristics and mechanical compatibility with the main part number. Variations in reverse recovery time (trr) and junction capacitance do not disqualify a part from substitution when all primary electrical ratings and package specifications remain unchanged.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Vishay Manufacturer):

S5D-E3/57T and S5D-E3/9AT are direct parametric equivalents manufactured by Vishay General Semiconductor - Diodes Division with Active product status. Both parts maintain identical electrical specifications and are available in Tape & Reel packaging. S5D-E3/57T provides the highest inventory availability at 15,300 pieces. S5D-E3/9AT offers 3,200 pieces in stock. Both parts are ROHS3 compliant and carry identical compliance certifications (REACH Unaffected, EAR99 ECCN classification).

Secondary Substitute (Discontinued Status):

S5D V7G, manufactured by Taiwan Semiconductor Corporation, is a parametric equivalent with identical voltage, current, and temperature ratings. However, this part is listed as Discontinued at DiGi Electronics and should be selected only when primary substitutes are unavailable. The S5D V7G exhibits a faster reverse recovery time (1.5 µs versus 2.5 µs) and higher junction capacitance (60 pF versus 40 pF), which may affect circuit performance in time-sensitive or high-frequency applications. This part is available in Cut Tape packaging rather than Tape & Reel format. Current inventory is limited to 1,137 pieces.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical Moisture Sensitivity Level (MSL 1 - Unlimited). No additional qualification or testing is required from a regulatory standpoint when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can S5D-E3/57T be used as a direct replacement for S5D-M3/9AT?

A: Yes. S5D-E3/57T is a parametric equivalent with identical electrical specifications across all critical parameters: 200 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage at 5 A, and DO-214AB surface mount packaging. Both parts are manufactured by Vishay and carry Active product status with ROHS3 compliance.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or smaller production runs. The S5D-M3/9AT, S5D-E3/57T, and S5D-E3/9AT are supplied in Tape & Reel format. The S5D V7G is supplied in Cut Tape format.

Q: Why does S5D V7G have different reverse recovery time and capacitance specifications?

A: S5D V7G is manufactured by Taiwan Semiconductor Corporation using different process technology than the Vishay parts. The faster reverse recovery time (1.5 µs) and higher capacitance (60 pF) reflect these manufacturing differences. Despite these variations, the part maintains identical voltage, current, and temperature ratings, making it a parametric equivalent for applications where these secondary characteristics do not impact circuit performance.

Q: Is S5D V7G recommended for new designs?

A: S5D V7G is listed as Discontinued at DiGi Electronics and should not be selected for new designs. Use S5D-E3/57T or S5D-E3/9AT as primary choices for new applications. S5D V7G is suitable only for replacement or repair of existing assemblies where this specific part number is already in use.

Q: Are there any temperature or compliance restrictions when substituting these parts?

A: No. All substitute parts operate across the identical temperature range (-55°C to 150°C junction temperature) and carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and EAR99 ECCN classification. Substitution does not require additional environmental or regulatory qualification.

Q: Which substitute part offers the best inventory availability?

A: S5D-E3/57T provides the highest inventory availability with 15,300 pieces in stock, compared to 3,200 pieces for S5D-E3/9AT and 1,137 pieces for S5D V7G. For applications requiring immediate delivery or large production quantities, S5D-E3/57T is the preferred substitute.
