Substitute Part Grouping Explanation

Substitution of the ES3A V6G is determined by strict equivalence across the following critical parameters:

Voltage Rating: 50 V DC reverse voltage (Vr) maximum
Current Rating: 3 A average rectified current (Io)
Speed Classification: Fast recovery diode with reverse recovery time ≤ 500 ns for currents > 200 mA
Package: DO-214AB (SMC) surface mount configuration
Temperature Range: -55°C to 150°C junction operating temperature
Compliance: ROHS3 compliance and MSL 1 rating

Substitute parts must match all electrical ratings and the physical package specification to ensure direct board-level compatibility without circuit redesign or layout modification.

Engineering Selection Recommendations

Direct Substitute - ES3A (Taiwan Semiconductor Corporation)

The ES3A is the active production equivalent of the discontinued ES3A V6G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications across all critical parameters: 50 V reverse voltage, 3 A average rectified current, 35 ns reverse recovery time, and DO-214AB package configuration. The ES3A maintains ROHS3 compliance and MSL 1 rating. With 17,100 units in stock, this part provides immediate availability for direct substitution without circuit modification.

Alternative Substitute - ES3AHE3_A/I (Vishay General Semiconductor - Diodes Division)

The ES3AHE3_A/I is a cross-manufacturer equivalent rated for identical voltage and current specifications with the same DO-214AB package. This part features a 30 ns reverse recovery time (5 ns faster than the main part), lower forward voltage drop (900 mV versus 950 mV at 3 A), and carries AEC-Q101 automotive qualification. The ES3AHE3_A/I is supplied in Tape & Reel packaging and is suitable for applications requiring automotive-grade components. This part is active in production with 1,106 units available.

Both substitute parts satisfy all electrical and mechanical requirements for direct board-level replacement of the ES3A V6G.

Frequently Asked Questions (FAQ)

Q: Can the ES3A directly replace the ES3A V6G without circuit modification?

A: Yes. The ES3A is manufactured by the same supplier (Taiwan Semiconductor Corporation) and shares identical electrical ratings: 50 V reverse voltage, 3 A average rectified current, 35 ns reverse recovery time, and DO-214AB surface mount package. No circuit redesign is required.

Q: What is the difference between the ES3A and ES3AHE3_A/I substitutes?

A: Both parts meet the core electrical requirements (50 V, 3 A, DO-214AB package). The ES3AHE3_A/I is manufactured by Vishay and offers improved performance characteristics: 30 ns reverse recovery time (versus 35 ns) and 900 mV forward voltage drop (versus 950 mV at 3 A). The ES3AHE3_A/I carries AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both the ES3A and ES3AHE3_A/I are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original ES3A V6G.

Q: Does the packaging format affect substitution?

A: The ES3A is supplied in standard packaging, while the ES3AHE3_A/I is supplied in Tape & Reel (TR) format. Both use the identical DO-214AB (SMC) component package for surface mount assembly. Tape & Reel packaging is standard for automated pick-and-place assembly and does not affect electrical or mechanical compatibility.

Q: Which substitute should be selected for automotive applications?

A: The ES3AHE3_A/I carries AEC-Q101 automotive qualification and is the appropriate selection for automotive-grade applications. The ES3A is suitable for general industrial and consumer applications.

Q: What is the inventory status of each substitute?

A: The ES3A has 17,100 units in stock (active production status). The ES3AHE3_A/I has 1,106 units in stock (active production status). Both parts are available for immediate procurement.
