ES3A-M3/57T Equivalent & Substitute Parts

Part Overview

The ES3A-M3/57T is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 50 V DC reverse voltage with a 3 A average rectified current rating and is packaged in the DO-214AB (SMC) form factor. The device is classified as Active product status and complies with RoHS3 and REACH regulations.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category. Alternatives become necessary when the primary part number reaches inventory constraints or when specific packaging formats are required for manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES3A-M3/57T is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 3 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA @ 50 V
• Capacitance @ Vr, F: 45 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance with the main part number. Variations in packaging format (Tape & Reel versus Cut Tape) and manufacturer do not affect functional interchangeability when electrical and mechanical specifications are equivalent.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with RoHS3 and REACH regulations. Selection between ES3A-M3/57T and its equivalents is determined by availability and packaging requirements rather than electrical performance.

ES3A-E3/57T (Vishay General Semiconductor - Diodes Division): Identical electrical specifications and Tape & Reel packaging. Current inventory of 5250 units provides extended availability.

ES3A-E3/9AT (Vishay General Semiconductor - Diodes Division): Identical electrical specifications and Tape & Reel packaging. Current inventory of 2177 units.

ES3A-13-F (Diodes Incorporated): Identical electrical specifications with reverse recovery time of 25 ns (improved from 30 ns). Supplied in Cut Tape and Digi-Reel® packaging formats. Current inventory of 10300 units provides maximum availability. Manufacturer change from Vishay to Diodes Incorporated does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ES3A-13-F be used as a direct replacement for ES3A-M3/57T?

A: Yes. The ES3A-13-F maintains all critical electrical parameters including 50 V reverse voltage, 3 A average rectified current, 900 mV forward voltage at 3 A, and identical package specifications (DO-214AB, SMC). The 25 ns reverse recovery time in ES3A-13-F is superior to the 30 ns specification of ES3A-M3/57T, ensuring compatibility in all applications. Both parts are RoHS3 compliant with MSL 1 rating.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape and Digi-Reel® packaging supplies components on cut tape segments or alternative reel formats, suitable for lower-volume or mixed-component assembly processes. Electrical and mechanical specifications remain identical across packaging formats.

Q: Are there electrical performance differences between Vishay and Diodes Incorporated versions?

A: No. Both manufacturers' versions of the ES3A series maintain identical electrical specifications for voltage rating, current capacity, forward voltage, and reverse leakage. The ES3A-13-F from Diodes Incorporated features a 25 ns reverse recovery time compared to 30 ns in Vishay versions, representing an improvement in switching performance.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use the identical DO-214AB (SMC) package footprint and mounting type (Surface Mount). PCB designs require no modification for component substitution.

Q: What compliance certifications apply to all substitute parts?

A: All parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Operating temperature range is -55°C to 150°C junction temperature across all variants.
