ES3B-M3/9AT Equivalent & Substitute Parts

Part Overview

The ES3B-M3/9AT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 100 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 a fast recovery diode with a 30 ns reverse recovery time, suitable for standard rectification applications requiring moderate switching speeds.

The ES3B-M3/9AT is an active product with full RoHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AB package family. Substitutes are necessary when the original part number is unavailable or when alternative packaging formats (Cut Tape versus Tape & Reel) are required for procurement or assembly operations.

Engineering Selection Recommendations

All four parts listed—ES3B-M3/9AT, ES3B-E3/57T, ES3B-E3/9AT, and ES3B-13-F—are active products with full regulatory compliance. Selection between these parts is determined by packaging and procurement requirements rather than electrical performance.

Vishay General Semiconductor - Diodes Division Parts (ES3B-M3/9AT, ES3B-E3/57T, ES3B-E3/9AT): These parts are electrically identical with matching reverse recovery time specifications of 30 ns. Selection between them depends on packaging format: Tape & Reel (TR) for automated assembly operations or Cut Tape (CT) for manual assembly and lower-volume applications.

Diodes Incorporated Part (ES3B-13-F): This part provides equivalent electrical performance with a faster reverse recovery time of 25 ns, which represents improved switching characteristics. The part is supplied in Tape & Reel format and is suitable for direct substitution in applications where faster recovery is beneficial or neutral.

All parts maintain identical forward voltage drop, reverse leakage current, and junction capacitance. All parts are RoHS3 compliant, REACH unaffected, and rated for the same operating temperature range of -55°C to 150°C with MSL 1 (Unlimited) moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Can ES3B-E3/57T be used as a direct replacement for ES3B-M3/9AT?

A: Yes. The ES3B-E3/57T is electrically identical to the ES3B-M3/9AT. The only difference is packaging format: ES3B-E3/57T is supplied in Cut Tape (CT) while ES3B-M3/9AT is supplied in Tape & Reel (TR). Both are surface mount diodes in DO-214AB packages with identical electrical specifications. Selection depends on assembly process requirements.

Q: What is the difference between ES3B-E3/9AT and ES3B-M3/9AT?

A: Both parts are supplied in Tape & Reel format and share identical electrical specifications. The difference lies in the base product designation (ES3B-E3 versus ES3B-M3), but all critical parameters—voltage rating, current rating, forward voltage, reverse recovery time, and operating temperature—are matched.

Q: Is ES3B-13-F from Diodes Incorporated compatible with the Vishay parts?

A: Yes. The ES3B-13-F is electrically compatible with all Vishay equivalents. It maintains the same 100 V reverse voltage rating, 3 A current rating, and 900 mV forward voltage drop. The reverse recovery time is 25 ns, which is faster than the 30 ns specification of the Vishay parts. This faster recovery is acceptable and does not create compatibility issues. All parts use the DO-214AB (SMC) package and are surface mount compatible.

Q: Are all these parts RoHS3 compliant?

A: Yes. All four parts—ES3B-M3/9AT, ES3B-E3/57T, ES3B-E3/9AT, and ES3B-13-F—are RoHS3 compliant and REACH unaffected. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Tape & Reel (TR) packaging is used for high-volume automated assembly operations where components are fed directly into pick-and-place machines. Cut Tape (CT) packaging is used for lower-volume applications, manual assembly, or when smaller quantities are required. The electrical performance of the component is identical regardless of packaging format.

Q: Can I substitute ES3B-13-F for ES3B-M3/9AT in a production assembly?

A: Yes. The ES3B-13-F is a direct electrical substitute. The faster reverse recovery time (25 ns versus 30 ns) represents improved performance and does not create compatibility issues. Both parts are active products with full compliance certifications and identical thermal operating ranges.

Q: What parameters must match for these parts to be considered equivalent?

A: The critical matching parameters are: 100 V DC reverse voltage rating, 3 A average rectified current, 900 mV maximum forward voltage drop at 3 A, DO-214AB (SMC) package, surface mount mounting type, and -55°C to 150°C operating temperature range. All substitute parts meet these specifications.
