Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 150 V (exact match required)
Diode Configuration: 1 Pair Common Cathode (exact match required)
Technology: Schottky (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: TO-220-3 (exact match required)

Secondary Substitution Parameters:

Current - Average Rectified (Io) (per Diode): 5 A minimum (equal or higher ratings acceptable)

Engineering Selection Recommendations

Direct Substitutes (MFR Recommended):

The MBR10150CT-G1 (Diodes Incorporated) and STPS10150CT (STMicroelectronics) are direct substitutes meeting identical electrical specifications at 5 A rated current. Both maintain 150 V reverse voltage, 1 pair common cathode configuration, and TO-220-3 packaging. MBR10150CT-G1 offers improved maximum junction temperature (175°C vs. 150°C) and lower reverse leakage current (50 µA vs. 1 mA). STPS10150CT provides comparable forward voltage characteristics with enhanced temperature rating.

Higher Current Rated Alternatives (MFR Recommended):

STPS20150CT, STPS30150CT, and STPS40150CT provide 10 A, 15 A, and 20 A rated currents respectively, all maintaining 150 V reverse voltage and TO-220-3 packaging. These components are suitable for applications requiring higher current capacity while preserving voltage and configuration specifications. All STMicroelectronics parts feature 175°C maximum junction temperature.

Parametric Equivalents:

10CTQ150 (SMC Diode Solutions) and MBR10150CT from Taiwan Semiconductor Corporation meet parametric equivalence criteria with identical 150 V reverse voltage and TO-220-3 configuration. These parts maintain Schottky technology and fast recovery characteristics. Selection between these and the primary part depends on circuit tolerance for forward voltage and reverse leakage variations, as well as compliance requirements specific to the application.

All substitute parts maintain RoHS3 compliance and EAR99 export classification consistent with the original MBR10150CT.

Frequently Asked Questions (FAQ)

Q: Can STPS20150CT replace MBR10150CT in a 5 A application?

A: Yes. STPS20150CT is rated for 10 A average rectified current per diode, which exceeds the 5 A requirement of the original application. The part maintains identical 150 V reverse voltage, 1 pair common cathode configuration, and TO-220-3 packaging. Forward voltage at 10 A (920 mV) is comparable to the original specification at 5 A (930 mV). Higher current rating provides design margin without compromising compatibility.

Q: What is the difference between MBR10150CT and MBR10150CT-G1?

A: Both parts share identical electrical ratings at 5 A: 150 V reverse voltage, 1 pair common cathode configuration, and TO-220-3 packaging. MBR10150CT-G1 (Diodes Incorporated) features lower reverse leakage current (50 µA vs. 1 mA at 150 V) and higher maximum junction temperature (175°C vs. 150°C). Forward voltage is slightly lower (890 mV vs. 930 mV at 5 A). These differences represent improved performance characteristics within the same functional category.

Q: Are all substitute parts available in the same TO-220-3 package?

A: Yes. All MFR recommended and parametric equivalent parts listed are packaged in TO-220-3 through-hole configuration, ensuring mechanical and thermal interface compatibility with the original MBR10150CT. Mounting footprint and heatsink interface requirements remain identical across all listed substitutes.

Q: What is the significance of reverse leakage current variation among substitutes?

A: Reverse leakage current ranges from 1 mA (MBR10150CT) to 50 µA (MBR10150CT-G1, 10CTQ150) across the substitute list. Lower reverse leakage reduces standby power dissipation and improves circuit efficiency in applications with sustained reverse bias conditions. Selection depends on circuit sensitivity to leakage current and thermal management requirements. All values remain within acceptable limits for standard rectification applications.

Q: Can MBR10150CT be replaced with STPS60150CT?

A: Yes, with design consideration. STPS60150CT maintains 150 V reverse voltage, 1 pair common cathode configuration, and TO-220-3 packaging. However, it is rated for 30 A average rectified current, significantly exceeding the 5 A requirement. This higher rating introduces design margin but may result in unnecessary cost and thermal characteristics not optimized for lower current applications. Selection should be based on circuit current requirements and cost considerations.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts maintain RoHS3 compliance and EAR99 export classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts except MBR20H150CTG (onsemi), which lists MSL as Not Applicable. REACH status is Unaffected for all parts except 10CTQ150, which is REACH Affected. Compliance verification should be confirmed for specific application and regional requirements.
