ES2FA R3G Equivalent & Substitute Parts

Part Overview

The ES2FA R3G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 300 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production continuity. The part exhibits fast recovery characteristics with a reverse recovery time of 35 nanoseconds, suitable for applications requiring efficient switching performance at moderate current levels.

Substitute Part Grouping Explanation

Substitution of the ES2FA R3G is determined by electrical and mechanical compatibility across the following critical parameters:

Parametric Equivalents maintain identical electrical specifications: 300 V reverse voltage rating, 2 A average rectified current, 1.3 V forward voltage drop at 2 A, 35 ns reverse recovery time, and DO-214AC package configuration. These parts satisfy direct replacement requirements without circuit redesign.

Similar Parts share the same reverse voltage rating (300 V) and package family but differ in current rating or recovery characteristics. The UFS130JE3/TR13 operates at 1 A instead of 2 A and uses a DO-214BA package variant, requiring evaluation of circuit current demands and board layout compatibility.

Substitution eligibility is restricted to parts meeting all of the following criteria:

Voltage - DC Reverse (Vr) (Max): 300 V minimum
Current - Average Rectified (Io): 2 A minimum
Package / Case: DO-214AC (SMA) or compatible surface mount configuration
RoHS3 Compliance
Operating Temperature Range: -55°C to 150°C minimum

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

The ES2FA and ES2FAH are parametric equivalents of the ES2FA R3G, maintaining identical electrical performance specifications and DO-214AC package configuration. Both parts are currently in active production status with substantial inventory availability (15,974 and 15,982 units respectively). Selection between these two options depends on application requirements:

ES2FA is suitable for general industrial and consumer applications requiring standard rectifier performance.
ES2FAH incorporates automotive-grade qualification (AEC-Q101) and is designated for automotive applications where enhanced reliability and traceability standards are mandated.

Both parts satisfy RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) requirements.

For Current-Limited Applications (Similar Part):

The UFS130JE3/TR13 manufactured by Microchip Technology operates at 1 A average rectified current, half the rating of the ES2FA R3G. This part is applicable only in circuits where the maximum current demand does not exceed 1 A. The UFS130JE3/TR13 uses a DO-214BA package, which differs from the DO-214AC configuration and requires board layout verification for footprint compatibility. The extended operating temperature range (-55°C to 175°C) provides thermal margin beyond the ES2FA R3G specification. Reverse recovery time is 50 nanoseconds, representing a 43% increase compared to the 35 ns specification of the main part.

Frequently Asked Questions (FAQ)

Q: Can the ES2FA directly replace the ES2FA R3G without circuit modification?

A: Yes. The ES2FA is a parametric equivalent with identical electrical specifications (300 V, 2 A, 1.3 V forward voltage, 35 ns recovery time) and the same DO-214AC package. No circuit redesign is required.

Q: What is the difference between ES2FA and ES2FAH?

A: Both parts are electrically identical. The ES2FAH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. Selection depends on whether the application requires automotive compliance certification.

Q: Can the UFS130JE3/TR13 be used as a direct substitute?

A: The UFS130JE3/TR13 is not a direct substitute. It is rated for 1 A instead of 2 A and uses a DO-214BA package instead of DO-214AC. It is suitable only for applications where circuit current does not exceed 1 A and where the different package footprint is accommodated in the board design.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The ES2FA, ES2FAH, and UFS130JE3/TR13 are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

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

A: DO-214AC (SMA) and DO-214BA are distinct surface mount diode package configurations with different physical dimensions and PCB footprints. Board layout verification is required before substituting parts with different package designations.

Q: Which substitute part has the best availability?

A: The ES2FAH has the highest inventory level at 15,982 units in stock, followed by ES2FA at 15,974 units. Both parts are in active production status.

Q: Does the ES2FAH automotive qualification affect performance in non-automotive applications?

A: No. The ES2FAH maintains identical electrical specifications to the ES2FA. Automotive qualification represents enhanced manufacturing and quality control standards and does not alter electrical performance characteristics.
