UFS570J/TR13 Equivalent & Substitute Parts

Part Overview

The UFS570J/TR13 is a general-purpose rectifier diode manufactured by Microchip Technology, rated for 700 V DC reverse voltage and 5 A average rectified current in a surface-mount DO-214AB package. This component is classified as Active product status and is designed for fast recovery applications with a reverse recovery time of 60 ns. The part is RoHS non-compliant and operates across a junction temperature range of -55°C to 175°C.

Substitute parts are identified based on equivalent electrical performance within the allowed parameter ranges for general-purpose rectifier diodes. Alternatives are selected when the main part is unavailable, when supply constraints exist, or when design requirements permit operation at reduced voltage or current ratings while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitute parts for the UFS570J/TR13 are grouped based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

Package compatibility: DO-214AB / SMC surface-mount package
Voltage rating: Minimum 600 V DC reverse voltage (lower than 700 V main part)
Current rating: 2 A to 6 A average rectified current (includes 5 A rated parts)
Speed classification: Fast Recovery or Standard Recovery
Reverse recovery time: 35 ns to 85 ns
Mounting type: Surface Mount
Temperature range: Minimum -55°C to 150°C junction temperature

Substitution Logic: Parts with 600 V ratings are acceptable substitutes for the 700 V main part when the application circuit operates below 600 V. Parts with current ratings from 2 A to 6 A accommodate designs where the 5 A specification can be met by higher-rated alternatives or where reduced current capacity is acceptable. Fast Recovery and Standard Recovery classifications both satisfy general-purpose rectification requirements. All substitute parts maintain the DO-214AB package footprint and surface-mount compatibility.

Engineering Selection Recommendations

For RoHS Compliance Requirements: All substitute parts listed (MURS360T3G, S5JL-TP, SMLJ60S6-TP, STTH2R06S, STTH3L06S, STTH3R06S) carry ROHS3 Compliant status. The main part UFS570J/TR13 is RoHS non-compliant. Selection of substitute parts is necessary when RoHS compliance is mandated by design specifications or regulatory requirements.

For Voltage Derating Applications: Substitute parts rated at 600 V are suitable for circuits operating below 600 V DC reverse voltage. The 100 V reduction from the main part's 700 V rating must be verified against the application's maximum reverse voltage exposure.

For Current Rating Compatibility:

S5JL-TP and SMLJ60S6-TP maintain or exceed the 5 A current specification of the main part
MURS360T3G, STTH2R06S, STTH3L06S, and STTH3R06S are rated below 5 A and are suitable only for applications requiring reduced current capacity

For Temperature Range Considerations: STTH2R06S operates to -40°C minimum (versus -55°C for the main part). S5JL-TP and SMLJ60S6-TP operate to 150°C maximum (versus 175°C for the main part). Temperature range limitations must be evaluated against application requirements.

For Fast Recovery Applications: MURS360T3G, STTH2R06S, STTH3L06S, and STTH3R06S maintain Fast Recovery classification. S5JL-TP and SMLJ60S6-TP are Standard Recovery devices and introduce longer reverse recovery times.

Frequently Asked Questions (FAQ)

Q: Can MURS360T3G replace UFS570J/TR13 in all applications?

A: MURS360T3G is a 600 V, 3 A Fast Recovery diode. It is suitable only for applications where the circuit operates below 600 V reverse voltage and requires no more than 3 A average rectified current. The 100 V voltage derating and 2 A current reduction must be verified against circuit requirements.

Q: What is the difference between S5JL-TP and SMLJ60S6-TP?

A: Both parts are 600 V rated and manufactured by Micro Commercial Co in DO-214AB packages. S5JL-TP is rated for 5 A with 1.2 V forward voltage at 5 A. SMLJ60S6-TP is rated for 6 A with 1.0 V forward voltage at 6 A and lower reverse leakage current (5 µA versus 10 µA). Both are Standard Recovery devices with operating temperature range to 150°C maximum.

Q: Why do some substitute parts have different reverse recovery times?

A: Reverse recovery time (trr) varies by manufacturer design and speed classification. Fast Recovery devices (STTH series, MURS360T3G) have trr values between 35 ns and 75 ns. Standard Recovery devices (S5JL-TP, SMLJ60S6-TP) do not specify trr but are classified as >500ns. Selection depends on whether the application requires fast switching performance.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-214AB surface-mount package (also designated SMC). Package footprint and land pattern compatibility are maintained across all listed alternatives.

Q: Can I use STTH2R06S as a direct replacement for UFS570J/TR13?

A: STTH2R06S is a 600 V, 2 A Fast Recovery diode. It is not a direct replacement due to the 2 A current rating, which is 60% below the main part's 5 A specification. Use is limited to applications where 2 A maximum current is acceptable.

Q: What is the impact of using a 600 V rated diode in a 700 V circuit?

A: A 600 V rated diode must not be used in circuits where reverse voltage can exceed 600 V. Exceeding the voltage rating causes device failure and potential circuit damage. Verify maximum reverse voltage in the application before selecting a 600 V substitute.

Q: Which substitute part has the lowest forward voltage drop?

A: SMLJ60S6-TP has the lowest forward voltage drop at 1.0 V @ 6 A. This characteristic reduces power dissipation in high-current applications. However, this part is Standard Recovery rated, which may not be suitable for fast-switching circuits.

Q: Do all substitute parts have the same temperature operating range as UFS570J/TR13?

A: No. UFS570J/TR13 operates from -55°C to 175°C. STTH2R06S operates from -40°C to 175°C (higher minimum). S5JL-TP and SMLJ60S6-TP operate from -55°C to 150°C (lower maximum). Temperature range compatibility must be verified for each application.
