Engineering Selection Recommendations

Primary Substitutes (Electrical and Mechanical Equivalence):

The following parts maintain full electrical equivalence with the UFS320J/TR13 across all critical parameters and are suitable for direct substitution in applications where the primary part is unavailable:

ES3D-E3/57T (Vishay): Identical reverse recovery time (30 ns), matching forward voltage (900 mV), and equivalent reverse leakage (10 µA). ROHS3 compliant. Operating temperature range -55°C to 150°C accommodates most industrial applications.
ES3DHE3_A/H and ES3DHE3_A/I (Vishay): Both feature AEC-Q101 automotive qualification with identical electrical specifications to ES3D-E3/57T. Suitable for applications requiring automotive-grade components.
MURS320-13-F (Diodes Incorporated): Superior forward voltage performance (875 mV vs. 950 mV), faster reverse recovery (25 ns), and extended temperature range (-65°C to 175°C). ROHS3 compliant. Recommended for high-efficiency applications.
ER3D-TP (Micro Commercial Co): Maintains 950 mV forward voltage matching the primary part, with slightly extended reverse recovery time (35 ns). ROHS3 compliant. Suitable for direct replacement.

Secondary Substitutes (Minor Parameter Variations):

ES3D-13-F (Diodes Incorporated): Forward voltage reduced to 900 mV with 25 ns reverse recovery. Operating temperature maximum limited to 150°C. ROHS3 compliant.
ES3D (Diotec Semiconductor): Superior reverse recovery performance (20 ns) and reduced forward voltage (900 mV). Operating temperature maximum limited to 150°C. ROHS3 compliant.
ESH3D-E3/57T (Vishay): Extended reverse recovery time (40 ns) with reduced reverse leakage (5 µA). Full temperature range (-55°C to 175°C) matching primary part. ROHS3 compliant.

Not Recommended for Direct Substitution:

S3D-13-F (Diodes Incorporated): Classified as standard recovery (>500 ns) rather than fast recovery. Forward voltage significantly elevated (1150 mV). Incompatible with fast recovery circuit requirements.

All recommended substitute parts are ROHS3 compliant, addressing environmental and regulatory requirements not met by the primary UFS320J/TR13 device.

Frequently Asked Questions (FAQ)

Q: Can I substitute the UFS320J/TR13 with any 200 V, 3 A diode in DO-214AB packaging?

A: No. The UFS320J/TR13 is specifically classified as a fast recovery diode with reverse recovery time ≤ 500 ns. Substitutes must maintain this speed classification. Standard recovery diodes (trr > 500 ns) are not electrically equivalent and will not function correctly in circuits designed for fast recovery characteristics.

Q: What is the significance of the 30 ns reverse recovery time specification?

A: Reverse recovery time determines how quickly the diode transitions from conducting to blocking state. The 30 ns specification is critical for high-frequency switching applications, power factor correction circuits, and switch-mode power supplies. Substitute parts with trr values between 20 ns and 40 ns remain within the fast recovery classification and are acceptable. Parts with significantly longer recovery times will cause circuit malfunction.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. The primary UFS320J/TR13 is RoHS non-compliant. If your application requires RoHS compliance, any of the listed substitutes will satisfy this requirement.

Q: Does forward voltage variation affect circuit performance?

A: Forward voltage variations between 875 mV and 950 mV are within acceptable design margins for most rectifier applications. However, in precision analog circuits or applications with tight voltage regulation requirements, forward voltage differences may require circuit re-evaluation. MURS320-13-F offers the lowest forward voltage (875 mV), while ER3D-TP matches the primary part at 950 mV.

Q: Can I use ES3DHE3_A/H or ES3DHE3_A/I in non-automotive applications?

A: Yes. These parts carry AEC-Q101 automotive qualification, which represents a higher reliability standard than standard industrial-grade components. They are fully suitable for non-automotive applications and offer enhanced reliability margins.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Both packaging formats contain identical components in DO-214AB (SMC) packages. Tape & Reel (TR) packaging is supplied on continuous reels for automated assembly equipment. Cut Tape (CT) is supplied in smaller quantities on tape segments. The electrical and mechanical specifications are identical; packaging format selection depends on assembly equipment compatibility and order quantity requirements.

Q: Is the operating temperature range critical for substitution?

A: The operating temperature range must encompass your application's maximum and minimum junction temperature requirements. The primary UFS320J/TR13 operates from -55°C to 175°C. Substitute parts with narrower ranges (such as -50°C to 150°C) are acceptable only if your application operates within those limits. MURS320-13-F and ESH3D-E3/57T offer extended ranges matching or exceeding the primary part.

Q: Why does S3D-13-F appear in the substitute list but is marked as not recommended?

A: S3D-13-F is listed because it shares the same voltage rating, current capacity, and package type. However, it is classified as standard recovery (>500 ns) rather than fast recovery. This fundamental difference in speed classification makes it electrically incompatible with circuits designed for the UFS320J/TR13's fast recovery characteristics. It is included for reference only to clarify why it is not suitable.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, provided all selected parts meet the same electrical specifications for your application. Mixing parts with different reverse recovery times (within the 20–40 ns range) or forward voltages (within the 875–950 mV range) is acceptable in most applications. However, for critical circuits, consistency across all diodes is recommended to ensure uniform circuit behavior.
