Current rating: 3 A average rectified current
Forward voltage drop: 1.7 V @ 3 A
Reverse recovery time: 35 ns
Reverse leakage current: 10 µA @ 500 V
Capacitance: 30 pF @ 4 V, 1 MHz
Package: DO-214AB (SMC) surface mount
Temperature range: -55°C to 150°C
Technology: Standard fast recovery diode
Compliance: ROHS3 compliant, REACH unaffected

Both substitute parts are manufactured by Taiwan Semiconductor Corporation and share the base product number ES3H, confirming their design lineage and functional equivalence to the original ES3H R6G.

Engineering Selection Recommendations

Both ES3HM6G and ES3HR7G are direct parametric equivalents to the discontinued ES3H R6G and are suitable for replacement in applications requiring a 500 V, 3 A fast recovery rectifier diode in DO-214AB surface mount packaging.

ES3HM6G carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. This part is appropriate for designs requiring automotive-level reliability and traceability.

ES3HR7G is classified as a standard industrial-grade component without automotive qualification. This part is appropriate for general industrial and consumer applications.

Both substitute parts maintain active product status, ensuring continued availability and supply chain stability. Both comply with ROHS3 and REACH requirements, matching the environmental compliance profile of the original ES3H R6G. Selection between the two substitutes depends on application requirements: automotive-qualified ES3HM6G for automotive designs, or standard ES3HR7G for non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ES3HM6G and ES3HR7G be used interchangeably with ES3H R6G?

A: Yes. Both substitute parts are parametric equivalents with identical electrical ratings (500 V, 3 A), forward voltage (1.7 V @ 3 A), reverse recovery time (35 ns), and package (DO-214AB). They are direct replacements from an electrical and mechanical standpoint.

Q: What is the difference between ES3HM6G and ES3HR7G?

A: ES3HM6G carries automotive-grade qualification (AEC-Q101) and is intended for automotive applications. ES3HR7G is a standard industrial-grade component. Both share identical electrical specifications and packaging. Selection depends on application classification.
