Core Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount

Substitution Categories:

Parametric Equivalents (Vishay General Semiconductor): Parts ES3D-E3/57T, ES3D-M3/57T, ES3DHE3_A/H, and ES3DHE3_A/I match all core electrical specifications and package requirements. These differ only in packaging format (Cut Tape vs. Tape & Reel) or automotive qualification level. ES3DHE3_A/H and ES3DHE3_A/I carry AEC-Q101 automotive qualification.

Direct Manufacturer Equivalents (Cross-Manufacturer): STTH3R02S (STMicroelectronics), ER3D-TP (Micro Commercial Co), ES3D (Diotec Semiconductor), MURS320-13-F (Diodes Incorporated), and S3D-TP (Micro Commercial Co) meet the 200 V / 3 A electrical specifications and DO-214AB package requirement. Minor variations exist in forward voltage, reverse recovery time, reverse leakage current, and operating temperature range, but all remain within fast recovery classification.

Non-Recommended Substitutes: SMLJ60S2-TP is excluded from primary substitution due to 6 A current rating, which exceeds the 3 A specification of the main part. S3D-TP carries "Not For New Designs" product status.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

ES3D-E3/57T, ES3D-M3/57T, ES3DHE3_A/H, and ES3DHE3_A/I are direct parametric equivalents manufactured by Vishay General Semiconductor. These parts maintain identical electrical specifications and are suitable for direct substitution. Selection between these variants depends on packaging format requirements: Cut Tape & Digi-Reel® for ES3D-E3/57T, or Tape & Reel for ES3D-M3/57T, ES3DHE3_A/H, and ES3DHE3_A/I. For automotive applications requiring AEC-Q101 qualification, ES3DHE3_A/H or ES3DHE3_A/I are specified.

Cross-Manufacturer Alternatives (Active Products):

STTH3R02S (STMicroelectronics), ER3D-TP (Micro Commercial Co), ES3D (Diotec Semiconductor), and MURS320-13-F (Diodes Incorporated) are active products meeting the 200 V / 3 A specification and DO-214AB package requirement. These parts exhibit minor variations in forward voltage drop (875 mV to 1000 mV @ 3 A) and reverse recovery time (20 ns to 35 ns), all within fast recovery classification. Selection is based on supply availability, packaging format preference, and thermal performance requirements within the specified operating temperature range.

Parts Not Recommended for New Designs:

S3D-TP carries "Not For New Designs" product status and exhibits higher forward voltage (1200 mV @ 3 A) and standard recovery characteristics, making it unsuitable for new applications.

Out-of-Specification Alternatives:

SMLJ60S2-TP is rated for 6 A average rectified current and does not meet the 3 A specification of the main part. This part is excluded from substitution consideration.

Frequently Asked Questions (FAQ)

Q: Can ES3D-E3/57T be used as a direct replacement for ES3D-E3/9AT?

A: Yes. ES3D-E3/57T is a parametric equivalent manufactured by Vishay General Semiconductor with identical electrical specifications (200 V, 3 A, 30 ns reverse recovery time, 900 mV forward voltage @ 3 A) and the same DO-214AB package. The difference is packaging format: ES3D-E3/57T is supplied in Cut Tape & Digi-Reel® format, while ES3D-E3/9AT uses the same format. Both are active products suitable for new designs.

Q: What is the difference between ES3D-M3/57T and ES3D-E3/57T?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is packaging format: ES3D-M3/57T is supplied in Tape & Reel (TR) format, while ES3D-E3/57T is supplied in Cut Tape & Digi-Reel® format. Selection depends on manufacturing process and component handling requirements.

Q: Are ES3DHE3_A/H and ES3DHE3_A/I suitable for automotive applications?

A: Yes. Both ES3DHE3_A/H and ES3DHE3_A/I carry AEC-Q101 automotive qualification and are classified as automotive-grade components. They maintain identical electrical specifications to the main part and are suitable for automotive circuit applications requiring qualified components.

Q: How does STTH3R02S compare to ES3D-E3/9AT?

A: STTH3R02S (STMicroelectronics) meets the 200 V / 3 A specification and DO-214AB package requirement. Minor differences include forward voltage of 1000 mV @ 3 A (versus 900 mV for the main part) and lower reverse leakage current of 3 µA @ 200 V (versus 10 µA). Both devices feature 30 ns reverse recovery time and fast recovery classification. STTH3R02S is an active product suitable for substitution.

Q: Why is S3D-TP not recommended for new designs?

A: S3D-TP carries "Not For New Designs" product status. Additionally, it exhibits higher forward voltage (1200 mV @ 3 A) and standard recovery characteristics (>500 ns), which differ from the fast recovery specification of the main part. New designs should utilize active products such as ES3D-E3/57T, STTH3R02S, or MURS320-13-F.

Q: Can SMLJ60S2-TP be used as a substitute?

A: No. SMLJ60S2-TP is rated for 6 A average rectified current, which exceeds the 3 A specification of the ES3D-E3/9AT. This part does not meet the electrical requirements for substitution and should not be used as a replacement.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Voltage - DC Reverse (Vr) (Max) of 200 V, (2) Current - Average Rectified (Io) of 3 A, (3) Fast Recovery speed classification (≤ 500ns, > 200mA), (4) DO-214AB (SMC) package, and (5) Surface Mount mounting type. All substitute parts listed meet these core requirements.

Q: What is the difference between Cut Tape & Digi-Reel® and Tape & Reel packaging?

A: Cut Tape & Digi-Reel® format supplies components on cut tape with optional reel packaging for automated handling. Tape & Reel (TR) format supplies components on continuous reel tape optimized for high-volume automated assembly. Selection depends on manufacturing equipment and production volume requirements.

Q: Does forward voltage variation affect circuit performance?

A: Forward voltage variations (875 mV to 1200 mV @ 3 A) among substitute parts may affect power dissipation and thermal performance in the application circuit. For applications with tight thermal budgets or high-frequency switching, forward voltage specifications should be reviewed against circuit requirements. All listed substitutes maintain fast recovery characteristics suitable for rectification applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance status, meeting environmental and hazardous substance restrictions. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage and assembly.
