Frequently Asked Questions (FAQ)

Q: Can ES2C M4G be directly replaced with ES2CH?

A: Yes. ES2CH meets all mandatory electrical and mechanical parameters. Both are 150 V, 2 A, DO-214AA surface mount diodes with identical forward voltage and recovery characteristics. ES2CH is active and automotive-qualified.

Q: What is the difference between parametric equivalents and similar parts?

A: Parametric equivalents (ES2C, ES2C R5G, ES2CH, ER2C_R1_00001) match all mandatory specifications with identical or superior performance. Similar parts (ES2C-13-F, ES2CHE3_A/H, ES2CHE3_A/I, ESH2C-E3/52T, ESH2C-E3/5BT) meet mandatory parameters but may have variations in secondary characteristics such as recovery time, leakage current, or temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of ES2C M4G.

Q: Can I use ESH2C-E3/52T in place of ES2C M4G?

A: Yes. ESH2C-E3/52T meets all mandatory parameters (150 V, 2 A, DO-214AA, surface mount). It offers superior reverse leakage (2 µA vs. 10 µA) and extended temperature range (-55°C ~ 175°C vs. -55°C ~ 150°C). Design verification is recommended for temperature-dependent applications.

Q: What packaging options are available for substitutes?

A: Most substitutes are available in standard surface mount DO-214AA (SMB) package. Specific packaging variants include Cut Tape (CT) for ES2C R5G and Tape & Reel (TR) for ES2C-13-F, ES2CHE3_A/H, ES2CHE3_A/I, ESH2C-E3/52T, ESH2C-E3/5BT, and ER2C_R1_00001.

Q: Which substitute offers the best forward voltage performance?

A: ES2C (Diotec Semiconductor) and ES2CHE3_A/H and ES2CHE3_A/I (Vishay) offer the lowest forward voltage at 900 mV @ 2 A, compared to 950 mV for ES2C M4G. This results in lower power dissipation in high-current applications.

Q: Are automotive-qualified alternatives available?

A: Yes. ES2CH, ES2CHE3_A/H, and ES2CHE3_A/I are automotive-grade with AEC-Q101 qualification, suitable for automotive and industrial applications requiring enhanced reliability standards.

Q: What is the reverse recovery time significance?

A: Reverse recovery time (trr) affects switching speed and efficiency. Faster recovery (20 ns in ES2C and ES2CHE3 variants vs. 35 ns in ES2C M4G) reduces switching losses and improves efficiency in high-frequency applications.
