ES2C-E3/52T (Parametric Equivalent)

This part is a direct parametric equivalent manufactured by Vishay General Semiconductor - Diodes Division. All electrical specifications, package configuration, and compliance certifications are identical to the ES2C-E3/5BT. The primary distinction is packaging format (Tape & Reel variant). This substitute is suitable for direct replacement in all applications. Product status is Active with ROHS3 compliance and unlimited moisture sensitivity rating.

STPS3150U (Direct Manufacturer Alternative)

The STPS3150U is manufactured by STMicroelectronics and utilizes Schottky technology rather than standard rectifier technology. This part meets the mandatory voltage (150 V) and package (DO-214AA, SMB) requirements. The current rating is higher at 3 A, providing additional design margin. Forward voltage is lower at 820 mV @ 3 A, resulting in reduced power dissipation. Operating temperature maximum extends to 175°C. This substitute is suitable for applications where lower forward voltage drop and higher current capacity are beneficial. Product status is Active with ROHS3 compliance.

Frequently Asked Questions (FAQ)

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

A: Yes. The ES2C-E3/52T is a parametric equivalent with identical electrical specifications, voltage rating, current rating, package type, and operating temperature range. The only difference is the packaging format (Tape & Reel variant). Direct substitution is appropriate for all applications.

Q: What is the primary difference between the STPS3150U and the ES2C-E3/5BT?

A: The STPS3150U uses Schottky technology while the ES2C-E3/5BT uses standard rectifier technology. The STPS3150U has a higher current rating (3 A vs. 2 A) and lower forward voltage (820 mV @ 3 A vs. 900 mV @ 2 A). Both meet the 150 V voltage requirement and use the same DO-214AA package. The Schottky technology results in lower power dissipation but may have different reverse leakage characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the main part ES2C-E3/5BT.

Q: What does "Last Time Buy" status mean for the MURS115T3G?

A: Last Time Buy status indicates that the manufacturer has discontinued active production of this part. Existing inventory is available but will not be replenished. This part should be considered for applications where long-term availability is not critical or where inventory can be secured before depletion.

Q: Can I use a substitute part with a higher current rating?

A: Yes. The STPS3150U has a 3 A current rating compared to the 2 A rating of the ES2C-E3/5BT. A higher current rating provides additional design margin and does not create compatibility issues. The part will operate safely at or below its rated current.

Q: What is the significance of reverse recovery time differences among the substitute parts?

A: Reverse recovery time (trr) affects switching speed and switching losses in high-frequency applications. The ES2C-E3/5BT has a 30 ns trr. Substitute parts range from 20 ns (ES2C) to 35 ns (MURS115T3G). Faster recovery times (lower trr values) reduce switching losses and are beneficial in high-frequency circuits. All listed parts meet the fast recovery classification requirement.

Q: Are all substitute parts available in the same DO-214AA package?

A: Yes. All substitute parts use the DO-214AA (SMB) package configuration, ensuring mechanical and thermal compatibility with the original design. Surface mount mounting type is consistent across all parts.

Q: What is the difference between forward voltage specifications at different current levels?

A: Forward voltage varies with current. The ES2C-E3/5BT specifies 900 mV @ 2 A, while the MURS115T3G specifies 875 mV @ 1 A. These measurements are taken at different operating currents. When comparing parts, forward voltage should be evaluated at the actual operating current of the application to ensure accurate power dissipation calculations.

Q: Can I substitute the ES2C-E3/5BT with the ES2C from Diotec?

A: Yes. The ES2C from Diotec is a parametric equivalent with matching voltage and current ratings. The operating temperature range is -50°C to 150°C, with the lower limit being 5°C higher than the main part. If your application operates within this temperature range, substitution is appropriate. The reverse recovery time is faster at 20 ns, which is beneficial for switching performance.

Q: What packaging options are available for these substitute parts?

A: The substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® packaging formats. All parts maintain the same DO-214AA (SMB) component package. Packaging format selection depends on assembly process requirements and volume considerations.
