ES1D-M3/5AT Equivalent & Substitute Parts

Part Overview

The ES1D-M3/5AT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 200 V DC reverse voltage with 1 A average rectified current in a DO-214AC (SMA) package. The part is classified as Active and complies with ROHS3 standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative part numbers may be required due to inventory availability, packaging format preferences, or application-specific qualification requirements such as automotive grade certifications.

Engineering Selection Recommendations

Vishay ES1D Series (Standard Grade): The ES1D-E3/5AT, ES1D-E3/61T, and ES1D-M3/61T are direct parametric equivalents to the ES1D-M3/5AT. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and tape configuration. Selection among these variants depends on assembly equipment compatibility and procurement format requirements. All maintain identical electrical specifications and Active product status.

Vishay ES1DHE3_A/H and ES1DHE3_A/I (Automotive Grade): These parts are qualified to AEC-Q101 automotive standards and are suitable for applications requiring automotive-grade components. Electrical parameters are identical to the standard ES1D-M3/5AT. Use these variants when automotive qualification is a design requirement.

Vishay U1D Series: The U1D-E3/5AT, U1D-E3/61T, and U1D-M3/5AT represent an alternative base product line with equivalent electrical performance. Reverse recovery time is 24 ns (versus 25 ns), which remains within fast recovery classification. These parts are Active and suitable for new designs. The U1D series may be selected based on inventory availability or supply chain strategy.

onsemi EGF1D: This part carries a "Not For New Designs" status and exhibits degraded electrical characteristics (Vf = 1000 mV, trr = 50 ns, Ir = 10 µA). Use only in legacy system maintenance or when no other alternatives are available.

Micro Commercial Co ES1D-LTP: This part is Active and maintains core electrical equivalence. Forward voltage is 950 mV (within acceptable tolerance) and reverse recovery time is 35 ns (still within fast recovery classification). This option is suitable for new designs and provides an alternative supply source.

Frequently Asked Questions (FAQ)

Q: Can I substitute ES1D-M3/5AT with ES1D-E3/5AT?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications. The difference is packaging format: ES1D-M3/5AT is supplied in Tape & Reel (TR), while ES1D-E3/5AT is supplied in Cut Tape (CT) & Digi-Reel®. Verify your assembly equipment accepts the packaging format before substitution.

Q: What is the difference between ES1D and U1D base product lines?

A: Both lines meet the 200 V, 1 A specification with fast recovery characteristics. The U1D series has a reverse recovery time of 24 ns compared to 25 ns for ES1D. This difference is negligible for most applications. Selection is based on inventory availability and supply chain considerations.

Q: Are automotive-grade variants (ES1DHE3_A/H, ES1DHE3_A/I) drop-in replacements?

A: Yes, for applications requiring AEC-Q101 qualification. Electrical parameters are identical to the standard ES1D-M3/5AT. Use these variants only when automotive qualification is specified in the design requirements.

Q: Can I use EGF1D from onsemi as a substitute?

A: EGF1D is not recommended for new designs due to its "Not For New Designs" status. Additionally, it exhibits higher forward voltage (1000 mV vs. 920 mV) and longer reverse recovery time (50 ns vs. 25 ns). Use only for legacy system maintenance when no other alternatives are available.

Q: What does the packaging designation (M3/5AT vs. E3/61T) mean?

A: The middle designation indicates tape format and reel configuration. M3 and E3 refer to different tape specifications. The suffix (5AT, 61T) indicates reel size and tape pitch. Consult your assembly equipment specifications to determine compatibility. Both formats contain identical components.

Q: Is Micro Commercial Co ES1D-LTP suitable for new designs?

A: Yes. ES1D-LTP is Active and maintains electrical equivalence with acceptable parameter variations (Vf = 950 mV, trr = 35 ns). This part provides an alternative supply source and is suitable for new designs.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: Voltage - DC Reverse (Vr) = 200 V, Current - Average Rectified (Io) = 1 A, Package = DO-214AC (SMA), Mounting Type = Surface Mount, and Speed Classification = Fast Recovery. Forward voltage, reverse recovery time, and leakage current must remain within acceptable tolerances. All substitute parts must be ROHS3 compliant with MSL 1.

Q: Can I mix packaging formats in the same assembly?

A: Yes, provided your assembly equipment supports both Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats. Verify feeder compatibility and tape specifications with your contract manufacturer before mixing formats in production.
