STTH2003CR Equivalent & Substitute Parts

Part Overview

The STTH2003CR is a general-purpose diode array manufactured by STMicroelectronics, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 300 V and average rectified current of 10 A per diode. The device is packaged in a TO-262-3 Long Leads (I2PAK) through-hole configuration and is classified as a fast recovery rectifier with a reverse recovery time of 35 nanoseconds. This component is currently in active production status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility.

• Current - Average Rectified (Io) (per Diode): 10 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 10 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 20 µA @ 300 V
• Package / Case: TO-262-3 Long Leads, I2PAK, TO-262AA
• Mounting Type: Through Hole
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

The VS-20CTH03-1-M3 manufactured by Vishay General Semiconductor - Diodes Division meets all critical electrical and mechanical parameters required for direct substitution with the STTH2003CR.

Parameter Comparison

Engineering Selection Recommendations

The VS-20CTH03-1-M3 is a direct parametric equivalent to the STTH2003CR. Both components are active production parts with identical electrical specifications, package configurations, and regulatory compliance certifications. The VS-20CTH03-1-M3 is manufactured by Vishay General Semiconductor - Diodes Division under the FRED Pt® series designation and maintains full compatibility with applications designed for the STTH2003CR.

Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN and HTSUS codes. The operating temperature range of the VS-20CTH03-1-M3 extends to −65°C, providing a broader temperature specification than the STTH2003CR maximum junction temperature of 175°C. This extended range does not restrict substitution in applications requiring the STTH2003CR specification.

Selection between these components should be based on availability, supply chain requirements, and procurement considerations rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the VS-20CTH03-1-M3 be used as a direct replacement for the STTH2003CR in existing circuit designs?

A: Yes. The VS-20CTH03-1-M3 meets all electrical and mechanical specifications of the STTH2003CR, including voltage rating, current rating, forward voltage drop, reverse recovery time, reverse leakage current, and package configuration. No circuit modifications are required.

Q: Are the package dimensions and pin configurations identical between these parts?

A: Yes. Both the STTH2003CR and VS-20CTH03-1-M3 use the TO-262-3 Long Leads (I2PAK, TO-262AA) through-hole package with identical pin configurations and mechanical dimensions.

Q: What is the significance of the FRED Pt® series designation for the VS-20CTH03-1-M3?

A: FRED Pt® is a Vishay product series designation for fast recovery epitaxial diodes. This designation indicates the technology platform used by Vishay but does not affect electrical equivalence with the STTH2003CR, which uses standard fast recovery rectifier technology with identical performance parameters.

Q: Do both parts have the same reverse recovery time specification?

A: Yes. Both the STTH2003CR and VS-20CTH03-1-M3 have a reverse recovery time (trr) of 35 nanoseconds, meeting the fast recovery classification of ≤ 500 ns for currents greater than 200 mA.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: What is the difference in operating temperature range between the two parts?

A: The STTH2003CR specifies a maximum junction temperature of 175°C. The VS-20CTH03-1-M3 specifies an operating temperature range of −65°C to 175°C. This extended lower temperature specification in the VS-20CTH03-1-M3 does not restrict its use in applications designed for the STTH2003CR.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Yes. Both parts are classified as fast recovery rectifiers with identical reverse recovery time specifications (35 ns) and forward voltage characteristics (1.25 V @ 10 A), making them suitable for the same high-frequency switching applications.

Q: Is there any difference in reverse leakage current between these parts?

A: No. Both the STTH2003CR and VS-20CTH03-1-M3 specify a reverse leakage current of 20 µA at 300 V reverse voltage.
