ES3F M6G Equivalent & Substitute Parts

Part Overview

The ES3F M6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 300 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts satisfy the same functional requirements within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the ES3F M6G is determined by equivalence in the following critical parameters: DC reverse voltage rating (300 V), average rectified current capacity (3 A), forward voltage drop characteristics, reverse recovery time, reverse leakage current, and surface mount package type (DO-214AB/SMC). All identified substitute parts maintain these core electrical specifications and mechanical compatibility.

The ES3F M6G substitutes into two distinct groupings:

Parametric Equivalent (ES3FH): Identical electrical specifications across all measured parameters, including forward voltage (1.3 V @ 3 A) and reverse recovery time (35 ns). Differs only in packaging format (Tape & Reel versus unspecified packaging for the main part) and product status (Active versus Discontinued).

Similar Substitutes (ES3FHE3_A/H, ES3FHE3_A/I): Manufactured by Vishay General Semiconductor - Diodes Division. These parts maintain identical reverse voltage (300 V), current rating (3 A), reverse leakage (10 µA @ 300 V), and package type (DO-214AB/SMC). Forward voltage is reduced to 1.1 V @ 3 A, and reverse recovery time is extended to 50 ns. Both parts carry automotive-grade qualification (AEC-Q101) and are supplied in Tape & Reel packaging.

Engineering Selection Recommendations

Primary Selection: ES3FH

The ES3FH is the direct parametric equivalent to the ES3F M6G, maintaining identical electrical performance across all specified parameters. This part is currently in active production status with substantial inventory availability (3,935 pieces). The ES3FH is suitable for direct replacement in applications where the original ES3F M6G specifications are required. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity classification.

Alternative Selection: ES3FHE3_A/H or ES3FHE3_A/I

The Vishay ES3FHE3_A/H and ES3FHE3_A/I parts are functionally compatible substitutes with the following considerations: forward voltage is reduced by 0.2 V (1.1 V versus 1.3 V @ 3 A), resulting in lower power dissipation in the diode. Reverse recovery time is extended by 15 ns (50 ns versus 35 ns), which may affect switching performance in high-frequency applications. Both parts carry automotive-grade qualification (AEC-Q101) and are actively produced. These substitutes are appropriate for applications where the reduced forward voltage drop provides design benefits and the extended recovery time does not compromise circuit performance.

All substitute parts maintain identical reverse voltage rating, current capacity, reverse leakage characteristics, and package compatibility with the original ES3F M6G specification.

Frequently Asked Questions (FAQ)

Q: Can the ES3FH be used as a direct replacement for the ES3F M6G?

A: Yes. The ES3FH maintains identical electrical specifications for voltage rating (300 V), current capacity (3 A), forward voltage (1.3 V @ 3 A), reverse recovery time (35 ns), and reverse leakage current (10 µA @ 300 V). Both parts use the DO-214AB (SMC) surface mount package and operate across the same temperature range (-55 to 150 °C). The primary difference is product status: ES3FH is active production while ES3F M6G is discontinued.

Q: What are the differences between the Vishay ES3FHE3_A/H and ES3FHE3_A/I parts?

A: The ES3FHE3_A/H and ES3FHE3_A/I are electrically identical. Both are manufactured by Vishay General Semiconductor - Diodes Division and carry AEC-Q101 automotive qualification. The designations _A/H and _A/I represent different manufacturing or packaging variants. Both parts are suitable for substitution where automotive-grade qualification is required.

Q: How does the reduced forward voltage of the Vishay substitutes affect circuit design?

A: The Vishay ES3FHE3_A/H and ES3FHE3_A/I parts exhibit forward voltage of 1.1 V @ 3 A compared to 1.3 V @ 3 A for the ES3F M6G. This 0.2 V reduction decreases power dissipation in the diode and may improve overall circuit efficiency. However, circuits designed with voltage drop compensation or regulation based on the original 1.3 V specification should be evaluated to confirm compatibility.

Q: Does the extended reverse recovery time of the Vishay parts affect performance?

A: The Vishay substitutes have reverse recovery time of 50 ns compared to 35 ns for the ES3F M6G. This 15 ns difference may impact switching performance in high-frequency rectification circuits or applications with rapid voltage transitions. Applications operating at frequencies below 100 kHz typically experience negligible performance impact. High-frequency switching applications should be evaluated to confirm the extended recovery time does not introduce unacceptable switching losses or EMI.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ES3F M6G, ES3FH, ES3FHE3_A/H, and ES3FHE3_A/I are all ROHS3 compliant. All parts carry unlimited moisture sensitivity classification (MSL 1).

Q: What is the packaging difference between the main part and substitutes?

A: All parts use identical DO-214AB (SMC) surface mount package and are mechanically compatible. The ES3FH and Vishay substitutes are supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production and automated assembly. The original ES3F M6G packaging format is not specified in the available data.

Q: Can the Vishay parts be used in automotive applications?

A: Yes. The ES3FHE3_A/H and ES3FHE3_A/I carry automotive-grade qualification (AEC-Q101), making them suitable for automotive applications. The ES3FH is standard grade and should be evaluated for automotive use based on specific application requirements.
