ES2CHE3_A/I Equivalent & Substitute Parts

Part Overview

The ES2CHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 150 V DC reverse voltage with a 2 A average rectified current rating and is packaged in the DO-214AA (SMB) form factor. The device is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters that define this diode's functional role in circuit applications. Alternative sources and packaging variants may be required due to inventory availability, supply chain considerations, or specific manufacturing process requirements.

Substitute Part Grouping Explanation

Substitution of the ES2CHE3_A/I is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 900 mV @ 2 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount

Compliance & Environmental Criteria:

RoHS Status: ROHS3 Compliant
Operating Temperature Range: -55°C to 150°C (or equivalent)

Parts ES2C-E3/52T and ES2C meet these substitution criteria. Both maintain the 150 V reverse voltage rating, 2 A average rectified current, 900 mV forward voltage drop, fast recovery speed classification, and DO-214AA SMB surface mount package. Both are ROHS3 compliant and operate within the specified temperature range.

Engineering Selection Recommendations

ES2C-E3/52T (Vishay General Semiconductor - Diodes Division): This substitute maintains full electrical and mechanical equivalence to the ES2CHE3_A/I. Both are manufactured by Vishay and share identical voltage, current, and forward voltage specifications. The reverse recovery time is 30 ns compared to 20 ns in the main part, and reverse leakage is specified at 150 V rather than 50 V. Both devices are ROHS3 compliant and rated for -55°C to 150°C operation. This part is suitable for direct substitution in applications where Vishay sourcing is preferred or required.

ES2C (Diotec Semiconductor): This substitute provides equivalent electrical performance with identical voltage, current, and forward voltage ratings. The reverse recovery time matches the main part at 20 ns, and reverse leakage is lower at 5 µA @ 150 V. The operating temperature range is -50°C to 150°C, which covers the primary operating window but does not extend to the full -55°C lower limit of the main part. This part is suitable for substitution in applications where the lower temperature limit of -50°C is acceptable and where Diotec sourcing is available.

Both substitute parts maintain the DO-214AA SMB surface mount package and are ROHS3 compliant, ensuring compatibility with existing PCB designs and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can ES2C-E3/52T be used as a direct replacement for ES2CHE3_A/I?

A: Yes. Both parts share identical voltage (150 V), current (2 A), and forward voltage (900 mV @ 2 A) specifications. Both are packaged in DO-214AA SMB and are ROHS3 compliant. The reverse recovery time differs by 10 ns (30 ns vs. 20 ns), which does not affect functional equivalence in general-purpose rectification applications.

Q: What is the difference between ES2C from Diotec and ES2C-E3/52T from Vishay?

A: Both parts meet the core electrical requirements of 150 V reverse voltage and 2 A average rectified current. The Diotec ES2C has a lower reverse leakage current (5 µA vs. 10 µA) and identical reverse recovery time (20 ns). The Diotec part has a minimum operating temperature of -50°C rather than -55°C. Both are packaged in DO-214AA SMB and are ROHS3 compliant.

Q: Are all three parts (ES2CHE3_A/I, ES2C-E3/52T, and ES2C) pin-compatible?

A: Yes. All three parts use the DO-214AA (SMB) package with identical pin configuration and footprint. They are mechanically and electrically interchangeable at the PCB level.

Q: Does the difference in reverse recovery time (20 ns vs. 30 ns) affect circuit performance?

A: Reverse recovery time affects switching speed and switching losses in high-frequency applications. The ES2CHE3_A/I and Diotec ES2C both specify 20 ns, while the Vishay ES2C-E3/52T specifies 30 ns. For general-purpose rectification at standard frequencies, this difference is not functionally significant. For high-frequency switching applications, the 20 ns specification is preferred.

Q: Can I use these parts in automotive applications?

A: The ES2CHE3_A/I carries AEC-Q101 automotive qualification. The substitute parts ES2C-E3/52T and ES2C are listed as Active products with ROHS3 compliance but do not explicitly reference AEC-Q101 qualification in the provided specifications. Automotive application requirements should be confirmed with the respective manufacturers.

Q: What is the minimum operating temperature for each part?

A: ES2CHE3_A/I and ES2C-E3/52T both operate from -55°C to 150°C. The Diotec ES2C operates from -50°C to 150°C. Applications requiring operation below -50°C must use either the main part or the Vishay substitute.
