ES2HA R3G Equivalent & Substitute Parts

Part Overview

The ES2HA R3G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 500 V DC reverse voltage and 2 A average rectified current in a DO-214AC (SMA) surface mount package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with acceptable parameter variations within the application envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES2HA R3G is determined by the following critical parameters: reverse voltage rating (500 V minimum), average rectified current capacity (2 A minimum for direct equivalents), forward voltage drop at rated current, reverse recovery time, and surface mount package compatibility. Parts are grouped into two categories:

Parametric Equivalents maintain all electrical specifications and package form factor, differing only in packaging format (Cut Tape versus Tape & Reel) or manufacturer source. These parts are direct functional replacements with no circuit redesign required.

Similar Substitutes provide the same reverse voltage rating and fast recovery speed classification but may differ in current rating, forward voltage characteristics, or package variant. These parts are suitable for applications where the specified current rating exceeds actual circuit requirements or where package footprint compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

ES2HA (Tape & Reel Format) is the primary replacement for ES2HA R3G. This part is manufactured by the same supplier (Taiwan Semiconductor Corporation) and maintains identical electrical specifications and package form factor. The only difference is packaging format: the original part is supplied in Cut Tape format, while the equivalent is supplied in Tape & Reel format. This part carries Active product status and is ROHS3 compliant.

AES2HF-HF is a parametric equivalent manufactured by Comchip Technology. It provides identical electrical performance (500 V, 2 A, 1.7 V forward drop, 35 ns recovery time) in the same DO-214AC (SMA) package. This part includes AEC-Q101 automotive qualification and exhibits lower reverse leakage current (5 µA versus 10 µA). This part carries Active product status and is ROHS3 compliant.

UFS150JE3/TR13 is a similar substitute manufactured by Microchip Technology. This part maintains the 500 V reverse voltage rating and fast recovery speed classification but is rated for 1 A average rectified current (versus 2 A for the main part). The forward voltage drop is lower (1.1 V @ 1 A), and reverse recovery time is slightly longer (50 ns versus 35 ns). The package is DO-214BA rather than DO-214AC, requiring PCB footprint verification. This part carries Active product status, is ROHS3 compliant, and supports extended operating temperature range (-55 to 175 °C). This part is suitable only for applications where the actual circuit current requirement does not exceed 1 A.

Frequently Asked Questions (FAQ)

Q: Can ES2HA (Tape & Reel) be used as a direct replacement for ES2HA R3G (Cut Tape)?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications (500 V, 2 A, 1.7 V forward drop, 35 ns recovery time) and package form factor (DO-214AC, SMA). The difference is packaging format only. Tape & Reel format is standard for high-volume production and assembly automation.

Q: What are the key differences between AES2HF-HF and ES2HA R3G?

A: Electrical specifications are identical: 500 V reverse voltage, 2 A current rating, 1.7 V forward drop, and 35 ns recovery time. AES2HF-HF is manufactured by Comchip Technology (versus Taiwan Semiconductor Corporation for the original part) and includes AEC-Q101 automotive qualification. Reverse leakage current is lower (5 µA versus 10 µA). Both use the same DO-214AC (SMA) package.

Q: Can UFS150JE3/TR13 replace ES2HA R3G in all applications?

A: UFS150JE3/TR13 is suitable only for applications where the actual circuit current requirement does not exceed 1 A. This part is rated for 1 A average rectified current, while ES2HA R3G is rated for 2 A. The reverse voltage rating (500 V) and speed classification (fast recovery) are identical. The package is DO-214BA instead of DO-214AC, requiring PCB footprint verification before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ES2HA, AES2HF-HF, and UFS150JE3/TR13 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the difference between DO-214AC and DO-214BA packages?

A: Both are surface mount diode packages with different physical dimensions and footprints. DO-214AC (SMA) is used by ES2HA R3G, ES2HA, and AES2HF-HF. DO-214BA is used by UFS150JE3/TR13. PCB layout and footprint must be verified before substituting between these package types.

Q: Which substitute part has the lowest reverse leakage current?

A: AES2HF-HF exhibits reverse leakage current of 5 µA @ 500 V, compared to 10 µA @ 500 V for ES2HA R3G and ES2HA. This lower leakage may provide performance benefits in high-impedance or precision analog circuits.

Q: Does UFS150JE3/TR13 support higher operating temperatures than ES2HA R3G?

A: Yes. UFS150JE3/TR13 supports operating junction temperature range of -55 to 175 °C, compared to -55 to 150 °C for ES2HA R3G. This extended temperature range may be beneficial for applications in elevated ambient conditions.
