Substitute Part Grouping Explanation

Substitution of the ESH2D-M3/52T is determined by strict equivalence across the following critical parameters:

Reverse Voltage Rating: 200 V DC maximum
Average Rectified Current: 2 A
Forward Voltage Drop: 930 mV maximum at 2 A
Package Type: DO-214AA (SMB) surface mount
Reverse Recovery Time: Fast recovery classification (≤ 500 ns)
Reverse Leakage Current: 2 µA at 200 V
Operating Temperature Range: -55°C to 175°C junction temperature

Engineering Selection Recommendations

All three substitute parts (ESH2D-E3/52T, ESH2D-E3/5BT, and ESH2DHE3_A/H) are functionally equivalent to the ESH2D-M3/52T for standard rectification applications. Selection among these options is based on the following criteria:

ESH2D-E3/52T and ESH2D-E3/5BT: These parts maintain identical electrical specifications to the main part, including the 35 nanosecond reverse recovery time. Both are ROHS3 compliant with MSL 1 rating and are suitable for general-purpose rectification in consumer and industrial applications.

ESH2DHE3_A/H: This part is qualified to AEC-Q101 automotive standards and carries an Automotive grade designation. The reverse recovery time is improved to 25 nanoseconds, providing faster switching characteristics. This part is appropriate for automotive applications requiring enhanced reliability and qualification documentation.

All parts maintain identical voltage, current, and thermal operating ranges. Selection should be based on application requirements (automotive versus standard), supply chain availability, and qualification documentation needs.

Frequently Asked Questions (FAQ)

Q: Can ESH2D-E3/52T be used as a direct replacement for ESH2D-M3/52T?

A: Yes. The ESH2D-E3/52T is a parametric equivalent with identical voltage (200 V), current (2 A), forward voltage drop (930 mV @ 2 A), reverse recovery time (35 ns), and package specifications (DO-214AA SMB). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ESH2D-E3/5BT and ESH2D-E3/52T?

A: Both parts are parametrically identical across all critical electrical specifications: 200 V reverse voltage, 2 A average rectified current, 930 mV forward voltage drop, 35 ns reverse recovery time, and DO-214AA SMB packaging. The difference lies in packaging configuration (tape and reel variant designation), not electrical performance.

Q: Is ESH2DHE3_A/H suitable for non-automotive applications?

A: Yes. The ESH2DHE3_A/H meets all electrical requirements of the ESH2D-M3/52T and exceeds them with a faster 25 nanosecond reverse recovery time. The automotive qualification and AEC-Q101 certification do not restrict use in standard applications; they indicate additional quality and reliability assurance.

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

A: Yes. All substitute parts are supplied in DO-214AA (SMB) surface mount packaging with Tape & Reel (TR) configuration, ensuring compatibility with standard pick-and-place assembly equipment and PCB layouts designed for the ESH2D-M3/52T.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: What is the significance of the reverse recovery time difference in ESH2DHE3_A/H?

A: The ESH2DHE3_A/H features a 25 nanosecond reverse recovery time compared to 35 nanoseconds in the main part and other substitutes. Both values fall within the fast recovery classification (≤ 500 ns). The faster recovery time in ESH2DHE3_A/H provides improved switching performance and reduced switching losses in high-frequency applications, while maintaining full compatibility with circuits designed for the standard 35 ns specification.

Q: Are all parts ROHS3 compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions for electronic components.
