ES2AHE3_A/I Equivalent & Substitute Parts

Part Overview

The ES2AHE3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 50 V DC reverse voltage with a 2 A average rectified current rating and features fast recovery characteristics with a 20 ns reverse recovery time. The device is housed in a DO-214AA (SMB) package and is qualified to AEC-Q101 automotive standards. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring 50 V, 2 A general-purpose rectification in surface mount configurations.

• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 2 A
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Speed Classification: Fast Recovery
• Reverse Recovery Time (trr): ≤ 30 ns
• Current - Reverse Leakage @ Vr: ≤ 10 µA @ 50 V
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all primary parameters and operating within secondary parameter tolerances are classified as parametric equivalents suitable for direct substitution in applications designed for the ES2AHE3_A/I.

Engineering Selection Recommendations

ES2A-E3/52T (Vishay General Semiconductor - Diodes Division)

The ES2A-E3/52T is a parametric equivalent manufactured by the same supplier as the primary part. It matches all critical electrical parameters including 50 V reverse voltage, 2 A average rectified current, and 900 mV forward voltage drop at 2 A. The reverse recovery time of 30 ns is within acceptable tolerance for fast recovery applications. Both parts share identical package specifications (DO-214AA, SMB), operating temperature range (-55°C to 150°C), and compliance certifications (ROHS3, MSL 1). This substitute is suitable for direct replacement in existing designs without circuit modification.

ES2A (YAGEO)

The ES2A from YAGEO meets the primary electrical specifications of 50 V reverse voltage and 2 A average rectified current in the DO-214AA package. The forward voltage specification of 0.95 V is equivalent to the 900 mV maximum at 2 A. This part maintains ROHS3 compliance and MSL 1 rating. However, detailed specifications for reverse recovery time and leakage current are not provided in the available data. This substitute is suitable for applications where detailed transient response characteristics are not critical design parameters.

Frequently Asked Questions (FAQ)

Q: Can ES2A-E3/52T be used as a direct replacement for ES2AHE3_A/I?

A: Yes. The ES2A-E3/52T is a parametric equivalent with matching voltage ratings (50 V), current ratings (2 A), forward voltage characteristics (900 mV @ 2 A), package type (DO-214AA, SMB), and operating temperature range (-55°C to 150°C). The 30 ns reverse recovery time is within acceptable tolerance for fast recovery rectifier applications. No circuit modifications are required.

Q: What is the difference in reverse recovery time between ES2AHE3_A/I and ES2A-E3/52T?

A: The ES2AHE3_A/I has a reverse recovery time of 20 ns, while the ES2A-E3/52T has 30 ns. Both are classified as fast recovery diodes. The 10 ns difference is within typical design margins for general-purpose rectification applications and does not affect functional compatibility in standard switching circuits.

Q: Is the YAGEO ES2A suitable for automotive applications?

A: The YAGEO ES2A meets the electrical requirements for 50 V, 2 A rectification and maintains ROHS3 compliance and MSL 1 rating. However, the provided data does not include AEC-Q101 automotive qualification information. Applications requiring automotive-grade certification should verify qualification status with the supplier before selection.

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

A: Yes. All three parts (ES2AHE3_A/I, ES2A-E3/52T, and ES2A) are supplied in DO-214AA (SMB) surface mount packages with Tape & Reel (TR) packaging. They are compatible with identical PCB footprints and automated assembly processes.

Q: What is the moisture sensitivity level for these diodes?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements. These parts do not require special moisture-barrier packaging or baking procedures prior to assembly.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: The ES2AHE3_A/I and ES2A-E3/52T are both specified as fast recovery diodes with reverse recovery times of 20 ns and 30 ns respectively, making them suitable for high-frequency switching. The YAGEO ES2A does not provide reverse recovery time specifications in the available data. For applications with critical switching frequency requirements, the Vishay parts are the preferred selection.
