Engineering Selection Recommendations

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

This part is a parametric equivalent to the ES2C-M3/52T with identical electrical specifications and packaging. Both devices are manufactured by Vishay and share the same base product number (ES2C). The ES2C-E3/52T maintains all critical parameters including 150 V reverse voltage, 2 A average rectified current, 900 mV forward voltage, and 30 ns reverse recovery time. Both are RoHS3 compliant with Active product status. This substitute is suitable for direct replacement in applications where Vishay sourcing is preferred or where higher inventory availability (30,400 pcs) is advantageous.

ES2C (Diotec Semiconductor)

This part meets all primary electrical and mechanical substitution criteria with 150 V reverse voltage, 2 A average rectified current, 900 mV forward voltage, and fast recovery speed classification. The Diotec ES2C demonstrates improved performance characteristics with 20 ns reverse recovery time (versus 30 ns) and 5 µA reverse leakage current (versus 10 µA). The device is RoHS3 compliant and Active product status. The operating temperature range is -50 to 150 °C, which is narrower at the lower bound compared to the -55 to 150 °C range of the Vishay variants. This substitute is suitable for applications where alternative manufacturer sourcing is acceptable and where the improved reverse recovery time and leakage characteristics provide system benefits. Inventory availability is 43,700 pcs.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications: 150 V reverse voltage, 2 A average rectified current, 900 mV forward voltage at 2 A, 30 ns reverse recovery time, and 10 µA reverse leakage current. Both are packaged in DO-214AA (SMB) surface mount form factor and are RoHS3 compliant with Active product status. The parts are electrically and mechanically interchangeable.

Q: What are the differences between the Vishay ES2C-M3/52T and the Diotec ES2C?

A: Both parts meet the primary electrical specifications of 150 V reverse voltage and 2 A average rectified current. The Diotec ES2C offers improved secondary performance with 20 ns reverse recovery time (compared to 30 ns) and 5 µA reverse leakage current (compared to 10 µA). The Diotec part has a narrower operating temperature range of -50 to 150 °C versus -55 to 150 °C for the Vishay variants. Both are packaged in DO-214AA (SMB) and are RoHS3 compliant.

Q: Are all three parts suitable for the same PCB layout and footprint?

A: Yes. All three parts use the DO-214AA (SMB) package with surface mount mounting type. The mechanical footprint and land pattern are identical, allowing direct substitution without PCB redesign.

Q: What is the significance of the reverse recovery time difference between the Vishay and Diotec parts?

A: Reverse recovery time (trr) is the time required for a diode to switch from forward conduction to reverse blocking. The Diotec ES2C has a 20 ns trr compared to 30 ns for the Vishay variants. This 10 ns difference may provide benefits in high-frequency switching applications or circuits sensitive to reverse recovery charge. For standard rectification applications, both specifications are within the fast recovery classification (≤ 500 ns).

Q: Does the lower reverse leakage current of the Diotec ES2C affect circuit performance?

A: The Diotec ES2C has 5 µA reverse leakage current compared to 10 µA for the Vishay parts, both measured at 150 V. Lower reverse leakage current reduces standby power dissipation and may improve performance in precision analog circuits or high-impedance applications. For standard rectification applications, both leakage specifications are acceptable.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are RoHS3 compliant and have Active product status. The Vishay parts include REACH Unaffected status and ECCN EAR99 classification. The Diotec ES2C indicates REACH info available upon request. All parts are suitable for commercial and industrial applications requiring RoHS compliance.

Q: What is the minimum operating temperature difference between the parts?

A: The Vishay ES2C-M3/52T and ES2C-E3/52T operate from -55 °C to 150 °C, while the Diotec ES2C operates from -50 °C to 150 °C. The Diotec part has a 5 °C higher minimum operating temperature. For applications requiring operation below -50 °C, the Vishay variants are required.
