MBR25150CT Equivalent & Substitute Parts

Part Overview

The MBR25150CT is a Schottky diode array with 1 pair common cathode configuration rated for 150 V DC reverse voltage and 25 A average rectified current per diode. This component is packaged in TO-220-3 through-hole format and is classified as discontinued at DiGi Electronics. The part is RoHS3 compliant and operates across a junction temperature range of -55°C to 150°C.

Due to the discontinued status of the MBR25150CT, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing. Substitute parts are selected based on matching or exceeding electrical specifications while maintaining mechanical compatibility with the TO-220-3 package.

Frequently Asked Questions (FAQ)

Q: Can the MBR25150CTHC0G be used as a direct replacement for the MBR25150CT?

A: Yes. The MBR25150CTHC0G is a direct parametric equivalent with identical electrical specifications (150 V reverse voltage, 25 A average rectified current, 1.02 V forward voltage at 25 A) and mechanical compatibility (TO-220-3 package). The primary difference is that MBR25150CTHC0G is currently active in production and carries automotive-grade qualification.

Q: What is the difference between standard-grade and automotive-grade parts?

A: Automotive-grade parts carry AEC-Q101 qualification, indicating compliance with automotive industry reliability and quality standards. These parts undergo additional testing and screening. Automotive-grade parts such as MBR25150CTHC0G and V40M150C-M3/4W are suitable for both automotive and general industrial applications.

Q: Can I use a lower current-rated part as a substitute?

A: Lower current-rated parts (5 A, 10 A, 15 A, 20 A) can be used only if your application does not require the full 25 A capacity. The 150 V reverse voltage rating is maintained across all substitute options. Verify that your circuit's maximum current demand does not exceed the substitute part's rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MBR25150CT specifications.

Q: What is the significance of the TO-220-3 package designation?

A: The TO-220-3 package is a through-hole component with three leads, designed for direct mounting on printed circuit boards. All substitute parts maintain this package format, ensuring mechanical and thermal compatibility with existing PCB layouts and heat sink mounting arrangements.

Q: How do forward voltage specifications affect part selection?

A: Forward voltage (Vf) varies with current rating. The original MBR25150CT specifies 1.02 V at 25 A. Lower current-rated substitutes exhibit different forward voltages at their respective current ratings. For example, V40M150C-M3/4W specifies 1.43 V at 20 A. Forward voltage affects power dissipation and thermal performance; verify that your circuit design accommodates the substitute part's forward voltage characteristics.

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

A: The original MBR25150CT operates from -55°C to 150°C junction temperature. Some automotive-grade substitutes such as V40M150C-M3/4W and V20150C-M3/4W extend the upper operating limit to 175°C and lower limit to -40°C. Extended temperature range parts provide enhanced performance in extreme thermal environments.

Q: Are there any differences in reverse leakage current between substitute parts?

A: Yes. Reverse leakage current (Ir) varies with current rating. The original part specifies 100 µA at 150 V. Lower current-rated parts exhibit lower leakage (50 µA for MBR10150CT-G1) while higher current-rated parts exhibit higher leakage (250 µA for V40150C-E3/4W). Reverse leakage affects standby power consumption; verify that your circuit design accommodates the substitute part's leakage characteristics.
