Engineering Selection Recommendations

Primary Recommendation: MBR20150SCT-G1

The MBR20150SCT-G1 manufactured by Diodes Incorporated is the direct equivalent to the obsolete MBR20150CT-LJ. This part maintains identical electrical specifications, automotive grade qualification (AEC-Q101), and ROHS3 compliance. The MBR20150SCT-G1 is active in production with established supply availability.

Secondary Recommendations: Cross-Manufacturer Equivalents

The following parts provide full electrical and mechanical compatibility:

DSA20C150PB (IXYS): Maintains 150 V, 10 A ratings with fast recovery characteristics. Forward voltage is 880 mV, slightly lower than the original specification. Reverse leakage is elevated at 300 µA but remains within acceptable operating parameters for Schottky diode arrays.
DSSK20-015A (IXYS): Provides the lowest forward voltage at 790 mV, beneficial for efficiency-critical applications. Reverse leakage is higher at 500 µA. Fast recovery speed is maintained.
MBR20150CT (Diotec Semiconductor): Offers the lowest reverse leakage at 5 µA and extended upper temperature rating to 175°C. Forward voltage is 850 mV. This part is suitable for applications requiring minimal leakage current.
MBR10150CT (Taiwan Semiconductor Corporation): Active production part with 10 A rating and fast recovery characteristics. Forward voltage is 980 mV. Maximum junction temperature is 150°C.
MBR10150CTHC0G (Taiwan Semiconductor Corporation): Automotive-qualified equivalent with AEC-Q101 certification. Forward voltage matches the original at 900 mV. Maximum junction temperature is 150°C.

Conditional Recommendation: DST20150C

The DST20150C (Littelfuse Inc.) maintains 150 V, 10 A ratings and fast recovery speed. Forward voltage is elevated at 1.2 V, which may impact thermal performance in high-current applications. Maximum junction temperature is limited to 150°C. This part is suitable for applications where forward voltage elevation is acceptable.

Conditional Recommendation: DSA10C150PB

The DSA10C150PB (IXYS) is rated for 5 A per diode, half the current rating of the original part. This part is suitable only for applications where the actual operating current does not exceed 5 A per diode.

All recommended parts are ROHS3 compliant and maintain through-hole TO-220-3 mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use DSA10C150PB as a direct replacement for MBR20150CT-LJ?

A: DSA10C150PB is rated for 5 A per diode, while the MBR20150CT-LJ is rated for 10 A per diode. This part is suitable only if your application operates at 5 A or below per diode. For applications requiring the full 10 A rating, use parts rated for 10 A or greater.

Q: What is the difference between MBR20150SCT-G1 and MBR20150CT-LJ?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. The primary difference is product status: MBR20150CT-LJ is obsolete, while MBR20150SCT-G1 is active in production. The MBR20150SCT-G1 is the direct replacement.

Q: Are all substitute parts automotive-qualified?

A: The MBR20150CT-LJ carries AEC-Q101 automotive qualification. Among the substitutes, MBR20150SCT-G1 and MBR10150CTHC0G also carry AEC-Q101 qualification. Other substitutes are not explicitly qualified to AEC-Q101 but are suitable for general industrial applications. Verify automotive qualification requirements for your specific application.

Q: How do forward voltage differences affect my circuit?

A: Forward voltage (Vf) variations between parts affect voltage drop across the diode. The MBR20150CT-LJ specifies 900 mV at 10 A. Substitutes range from 790 mV (DSSK20-015A) to 1200 mV (DST20150C). Lower Vf reduces power dissipation; higher Vf increases it. Verify that your circuit design accommodates the Vf of the selected substitute part.

Q: What does reverse leakage current mean?

A: Reverse leakage current is the small current that flows through the diode when reverse-biased. The MBR20150CT-LJ specifies 50 µA at 150 V. Higher leakage (such as 500 µA in DSSK20-015A) increases standby power consumption but does not affect forward conduction performance. Lower leakage (such as 5 µA in MBR20150CT) reduces standby power.

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

A: All substitute parts listed are packaged in TO-220-3 through-hole format, maintaining mechanical compatibility with the original MBR20150CT-LJ. Verify specific packaging details (tube, tray, or bulk) with your supplier for procurement purposes.

Q: Can I use MBR20150CT from Diotec Semiconductor instead of the Diodes Incorporated part?

A: Yes. The MBR20150CT from Diotec Semiconductor maintains the required 150 V, 10 A ratings and TO-220-3 package. It offers superior reverse leakage performance (5 µA) and extended temperature rating to 175°C. This part is suitable for direct replacement in applications where these characteristics are beneficial.

Q: What is the operating temperature range I should consider?

A: The MBR20150CT-LJ operates from −55°C to 175°C junction temperature. Most substitute parts operate to 150°C maximum. If your application requires operation above 150°C, use MBR20150SCT-G1 (−55 to 175°C) or MBR20150CT from Diotec (−50 to 175°C).

Q: Are all parts RoHS3 compliant?

A: All substitute parts listed are ROHS3 compliant, matching the environmental compliance of the original MBR20150CT-LJ.
