ES3D Equivalent & Substitute Parts

Part Overview

The ES3D is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This part is classified as Active and complies with RoHS3 standards. The ES3D serves as a standard fast recovery diode suitable for general rectification applications requiring moderate voltage and current ratings.

Substitute parts are necessary when the primary ES3D becomes unavailable due to supply constraints, inventory limitations, or when alternative manufacturers' components are preferred for cost optimization, supply chain diversification, or specific application requirements such as automotive qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the ES3D is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) Maximum: 200 V
Current - Average Rectified (Io): 3 A
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) or Standard Recovery >500ns, > 200mA (Io)
Operating Temperature Range: Must encompass or match the application requirement
Reverse Recovery Time (trr): Acceptable range 20 ns to 35 ns for fast recovery variants
Current - Reverse Leakage @ Vr: 1 µA to 10 µA @ 200 V

Substitute parts are grouped into two categories:

Category A - Direct Fast Recovery Equivalents: Parts with identical voltage, current, package, and fast recovery speed characteristics (trr ≤ 35 ns). These include ACEFC304-HF, ER3D-TP, ER3D_R1_00001, ES3DHE3_A/H, ES3DHE3_A/I, MURS320-E3/57T, and MURS320-E3/9AT.

Category B - Standard Recovery Alternatives: Parts with identical voltage, current, and package but standard recovery speed (>500 ns). These include CMR3-02 TR13 PBFREE and S3D-13-F. These parts are suitable for applications where fast recovery is not a critical requirement.

Engineering Selection Recommendations

For Active Product Status Applications:

All substitute parts listed maintain Active product status except S3D-TP, which is designated as Not For New Designs. For new design implementations, select from the Active status parts only.

For Fast Recovery Requirements:

When the application requires fast recovery characteristics (trr ≤ 35 ns), select from Category A equivalents: ACEFC304-HF, ER3D-TP, ER3D_R1_00001, ES3DHE3_A/H, ES3DHE3_A/I, MURS320-E3/57T, or MURS320-E3/9AT. All maintain the fast recovery speed classification of the original ES3D.

For Automotive Applications:

When automotive-grade qualification is required, select ACEFC304-HF, ES3DHE3_A/H, or ES3DHE3_A/I. These parts carry AEC-Q101 qualification and Automotive grade designation.

For Extended Temperature Range:

When operating temperature range must extend beyond -55°C to 150°C, select from parts rated -65°C to 175°C: CMR3-02 TR13 PBFREE, MURS320-E3/57T, or MURS320-E3/9AT.

For Standard Recovery Applications:

When fast recovery is not required and cost optimization is prioritized, CMR3-02 TR13 PBFREE or S3D-13-F provide standard recovery alternatives with identical voltage and current ratings. Note that S3D-TP is not recommended for new designs.

For Reverse Leakage Minimization:

When lowest reverse leakage current is critical, ER3D_R1_00001 provides 1 µA @ 200 V, compared to 5-10 µA in other alternatives.

Compliance Verification:

All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the original ES3D specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute ES3D with any 200 V, 3 A diode in DO-214AB package?

A: No. Substitution requires matching voltage (200 V), current (3 A), and package (DO-214AB, SMC) specifications. Additionally, the speed classification (fast recovery vs. standard recovery) must be compatible with the application circuit requirements. Forward voltage drop (Vf) and reverse recovery time (trr) may affect circuit performance and must be evaluated for the specific application.

Q: What is the difference between fast recovery and standard recovery diodes in this list?

A: Fast recovery diodes (trr ≤ 500 ns, typically 20-35 ns) are suitable for high-frequency switching applications and reduce switching losses. Standard recovery diodes (trr >500 ns) are adequate for lower-frequency rectification and general-purpose applications. The ES3D is a fast recovery device; substitutes must maintain this characteristic unless the application permits standard recovery operation.

Q: Are automotive-grade parts (ACEFC304-HF, ES3DHE3_A/H, ES3DHE3_A/I) interchangeable with non-automotive parts?

A: Automotive-grade parts with AEC-Q101 qualification meet stricter reliability and quality standards. They are functionally interchangeable with non-automotive equivalents in non-automotive applications. However, automotive applications require automotive-grade components; non-automotive parts are not suitable for automotive use.

Q: What does "Not For New Designs" mean for S3D-TP?

A: This designation indicates the part is in mature or end-of-life status and should not be selected for new product designs. Existing designs using S3D-TP may continue operation, but new designs should select from Active status alternatives such as ER3D-TP, MURS320-E3/9AT, or other Active-status parts.

Q: How do I determine if a substitute part will work in my circuit?

A: Verify that the substitute part meets or exceeds the following minimum requirements: (1) Voltage - DC Reverse rating ≥ application peak reverse voltage; (2) Current - Average Rectified rating ≥ application average forward current; (3) Speed classification matches application frequency requirements; (4) Operating temperature range encompasses the application environment; (5) Package and mounting type are compatible with PCB design. Forward voltage drop (Vf) differences may require circuit analysis if voltage regulation is critical.

Q: Can I use MURS320-E3/57T (Cut Tape packaging) instead of ES3D (Cut Tape packaging)?

A: Yes. Both parts are supplied in Cut Tape (CT) packaging and are electrically equivalent. MURS320-E3/57T provides identical 200 V, 3 A ratings with fast recovery characteristics (trr 35 ns) and extended temperature range (-65°C to 175°C). Verify that the extended temperature range does not introduce thermal stress in the application.

Q: What is the significance of reverse leakage current (Ir) differences between substitutes?

A: Reverse leakage current affects circuit performance in high-impedance applications and influences power dissipation. The ES3D specifies 10 µA @ 200 V. Substitutes range from 1 µA (ER3D_R1_00001) to 10 µA. Lower leakage is beneficial in precision rectification circuits; higher leakage is acceptable in general-purpose applications. Verify leakage specifications against application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the original ES3D. This ensures environmental and regulatory compatibility across all alternatives.
