Engineering Selection Recommendations

ES2C-E3/52T (Vishay General Semiconductor - Diodes Division)

This part is a parametric equivalent to the ES2C-M3/5BT with identical electrical specifications and packaging. Both devices share the same manufacturer, base product number (ES2C), and are rated for 150 V, 2 A operation in DO-214AA (SMB) packages. The ES2C-E3/52T offers significantly higher inventory availability (30,400 pcs vs. 921 pcs) and maintains identical compliance certifications including RoHS3 and MSL 1 (Unlimited). This substitute is suitable for direct replacement in all applications where the ES2C-M3/5BT is specified.

ES2C-13-F (Diodes Incorporated)

This manufacturer-recommended substitute meets all critical electrical parameters with 150 V reverse voltage and 2 A average rectified current in the same DO-214AA (SMB) package. The ES2C-13-F exhibits improved performance characteristics including faster reverse recovery time (25 ns vs. 30 ns) and lower reverse leakage current (5 µA vs. 10 µA). Forward voltage is marginally higher at 920 mV compared to 900 mV, which remains within acceptable engineering tolerance for general-purpose rectifier applications. RoHS3 compliance and MSL 1 (Unlimited) rating are maintained. This substitute is suitable for applications where improved switching performance is beneficial.

ES2C (Diotec Semiconductor)

This parametric equivalent provides 150 V, 2 A operation in DO-214AA (SMB) packaging with superior reverse recovery time performance (20 ns). The device maintains identical forward voltage (900 mV) and reduced reverse leakage current (5 µA). Operating temperature range extends to -50°C minimum (vs. -55°C), which covers standard industrial applications. RoHS3 compliance is confirmed. Inventory availability is highest among all substitutes (43,700 pcs). This substitute is suitable for applications prioritizing fast switching performance and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ES2C-E3/52T be used as a direct replacement for ES2C-M3/5BT?

A: Yes. The ES2C-E3/52T is a parametric equivalent with identical voltage rating (150 V), current rating (2 A), forward voltage (900 mV @ 2 A), reverse recovery time (30 ns), reverse leakage current (10 µA @ 150 V), and package (DO-214AA, SMB). Both devices are manufactured by Vishay General Semiconductor and share the same base product number. No circuit modifications are required.

Q: What are the differences between ES2C-13-F and the original ES2C-M3/5BT?

A: The ES2C-13-F is manufactured by Diodes Incorporated rather than Vishay. Electrical differences include forward voltage of 920 mV (vs. 900 mV), faster reverse recovery time of 25 ns (vs. 30 ns), lower reverse leakage current of 5 µA (vs. 10 µA), and higher capacitance of 25 pF (vs. 18 pF). All devices maintain 150 V reverse voltage, 2 A current rating, and DO-214AA (SMB) packaging. These differences represent improved performance characteristics suitable for high-frequency switching applications.

Q: Is the Diotec ES2C suitable for all applications requiring ES2C-M3/5BT?

A: The Diotec ES2C meets all critical electrical parameters: 150 V reverse voltage, 2 A average rectified current, fast recovery speed classification, and DO-214AA (SMB) packaging. The minimum operating temperature is -50°C (vs. -55°C for the original), which is acceptable for standard industrial and commercial temperature ranges. The superior reverse recovery time (20 ns) makes this substitute particularly suitable for high-frequency rectification circuits. Substitution is appropriate for applications within the -50°C to 150°C operating range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ES2C-E3/52T, ES2C-13-F, and ES2C from Diotec) are RoHS3 compliant. The original ES2C-M3/5BT is also RoHS3 compliant. This compliance status is maintained across all substitutes.

Q: What is the significance of MSL (Moisture Sensitivity Level) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. The ES2C-M3/5BT, ES2C-E3/52T, and ES2C-13-F all carry MSL 1 (Unlimited) ratings. The Diotec ES2C lists MSL as Not Applicable, indicating no moisture sensitivity restrictions. All parts are suitable for standard PCB assembly processes without special moisture precautions.

Q: Can reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and switching losses in rectifier circuits. The ES2C-M3/5BT has trr of 30 ns, while ES2C-13-F has 25 ns and Diotec ES2C has 20 ns. Faster recovery times reduce switching losses and enable higher-frequency operation. For applications operating at frequencies below 100 kHz, these differences are generally not significant. For high-frequency switching applications above 100 kHz, the faster recovery time of ES2C-13-F or Diotec ES2C may provide performance benefits.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are packaged in DO-214AA (SMB) surface mount format, identical to the ES2C-M3/5BT. This ensures mechanical compatibility with existing PCB layouts and assembly processes. No modifications to board design or pick-and-place programming are required when substituting between these parts.
