Engineering Selection Recommendations

STPS40H100CW is the direct equivalent substitute for the MBR20100PTHC0G. Both parts share identical current ratings of 20 A per diode, 100 V reverse voltage, and TO-247-3 through-hole packaging. The STPS40H100CW demonstrates superior forward voltage characteristics (730 mV vs. 950 mV at 20 A) and lower reverse leakage current (10 µA vs. 100 µA at 100 V). Both parts are ROHS3 compliant, MSL 1, and maintain fast recovery Schottky technology specifications. The STPS40H100CW is manufactured by STMicroelectronics with 2921 pieces currently in stock.

STPS61H100CW is a higher-current substitute rated for 30 A per diode. This part is suitable for applications where the MBR20100PTHC0G current capacity is insufficient or where design margin is required. The STPS61H100CW maintains all core electrical and mechanical compatibility parameters with improved thermal performance characteristics. STMicroelectronics manufactures this part with 9230 pieces in stock.

STPS30H100CW is a lower-current substitute rated for 15 A per diode. This part is suitable only for applications where the circuit design permits reduced current capacity. The STPS30H100CW demonstrates the lowest forward voltage (800 mV at 15 A) and reverse leakage current (5 µA at 100 V) among all listed substitutes. This part is manufactured by STMicroelectronics with 22238 pieces in stock.

All substitute parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity classification. Selection between substitutes depends on application current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can the STPS40H100CW directly replace the MBR20100PTHC0G without circuit modification?

A: Yes. The STPS40H100CW is a direct equivalent with identical current rating (20 A), reverse voltage (100 V), diode configuration (1 Pair Common Cathode), and TO-247-3 through-hole packaging. No circuit modification is required.

Q: What is the difference between the STPS30H100CW and STPS40H100CW?

A: The STPS30H100CW is rated for 15 A per diode, while the STPS40H100CW is rated for 20 A per diode. The STPS30H100CW exhibits lower forward voltage (800 mV vs. 730 mV at rated current) and lower reverse leakage current (5 µA vs. 10 µA). Selection depends on application current requirements.

Q: Is the STPS61H100CW suitable for all applications using the MBR20100PTHC0G?

A: The STPS61H100CW is suitable for applications where the MBR20100PTHC0G is used. The higher current rating (30 A vs. 20 A) provides additional design margin and thermal performance. No circuit modification is required for substitution.

Q: Are all substitute parts qualified to the same automotive standards as the MBR20100PTHC0G?

A: The MBR20100PTHC0G carries AEC-Q101 automotive qualification. The substitute parts (STPS30H100CW, STPS40H100CW, STPS61H100CW) are manufactured by STMicroelectronics and are ROHS3 compliant with MSL 1 classification. Automotive qualification status for substitute parts must be verified against specific application requirements.

Q: What is the impact of forward voltage differences between substitute parts?

A: Forward voltage differences affect power dissipation and thermal performance. The STPS40H100CW (730 mV @ 20 A) dissipates less power than the MBR20100PTHC0G (950 mV @ 20 A) at identical current levels. The STPS61H100CW (790 mV @ 30 A) exhibits intermediate forward voltage characteristics. Lower forward voltage reduces thermal load in high-current applications.

Q: Can the MBR20100PTHC0G be substituted with lower-current parts in existing designs?

A: Substitution with lower-current parts (STPS30H100CW at 15 A) is only permissible if the application circuit design permits reduced current capacity. The circuit must be analyzed to confirm that peak and average current demands do not exceed the substitute part rating.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are packaged in TO-247-3 through-hole configuration, identical to the MBR20100PTHC0G. Mechanical mounting and thermal interface requirements are equivalent across all listed parts.

Q: What is the reverse leakage current significance in substitute selection?

A: Reverse leakage current affects circuit performance in high-impedance applications and thermal stability. The MBR20100PTHC0G exhibits 100 µA @ 100 V leakage. Substitute parts demonstrate lower leakage: STPS40H100CW (10 µA), STPS61H100CW (16 µA), and STPS30H100CW (5 µA). Lower leakage improves circuit efficiency and reduces standby power consumption.
