Equivalent & Substitute Parts for S3D-M3/9AT

Part Overview

The S3D-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 3 A average rectified current rating and is housed in a DO-214AB (SMC) package. The device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to packaging format availability, inventory constraints, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the S3D-M3/9AT is determined by electrical parameter equivalence and mechanical compatibility. The critical parameters that define substitutability are:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2.5 A
• Reverse Recovery Time (trr): 2.5 µs
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

The S3D-M3/9AT is supplied in Tape & Reel (TR) packaging format. The identified substitute part S3D-E3/57T is supplied in Cut Tape (CT) packaging format. Both parts share identical electrical specifications and the same DO-214AB (SMC) package, making them functionally equivalent. The packaging difference reflects alternative distribution and handling methods suitable for different manufacturing environments and procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

The S3D-E3/57T is a direct electrical and mechanical equivalent to the S3D-M3/9AT. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, carry Active product status, and meet ROHS3 compliance requirements. The parts are identical in all electrical parameters, thermal operating range, and package form factor (DO-214AB SMC).

The only distinction between these parts is the packaging format: S3D-M3/9AT is supplied in Tape & Reel (TR) format, while S3D-E3/57T is supplied in Cut Tape (CT) format. This difference does not affect electrical performance or circuit functionality. Selection between these parts should be based on manufacturing process requirements, automated assembly equipment compatibility, and supply chain availability.

Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status, indicating no additional handling or storage constraints beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can S3D-E3/57T be used as a direct replacement for S3D-M3/9AT in circuit applications?

A: Yes. The S3D-E3/57T is electrically and mechanically equivalent to the S3D-M3/9AT. All electrical parameters, including reverse voltage, forward current, forward voltage drop, reverse recovery time, and leakage current are identical. Both parts use the same DO-214AB (SMC) package and surface mount configuration.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for high-volume automated assembly lines. Cut Tape (CT) packaging supplies components on tape segments of fixed length, typically used for lower-volume production or manual assembly processes. The electrical and mechanical properties of the component itself remain unchanged.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both S3D-M3/9AT and S3D-E3/57T operate across the same junction temperature range of -55°C to 150°C. Both maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control requirements during storage or handling.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH Unaffected. They carry identical regulatory and environmental compliance certifications.

Q: Which part should be selected for new designs?

A: Selection should be based on manufacturing process requirements and supply chain considerations. If the production line uses automated tape-fed assembly equipment, Tape & Reel (TR) format may be preferred. If manual assembly or lower-volume production is used, Cut Tape (CT) format may be more suitable. Electrical performance is identical between both options.
