Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS30150CT is determined by the following critical parameters: diode configuration (1 pair common cathode), technology (Schottky), reverse voltage rating (150 V), average rectified current per diode, forward voltage characteristics, fast recovery speed, and through-hole mounting capability. Parts are grouped into three categories based on substitution relationship:

Parametric Equivalent (Same Electrical Specifications, Different Package): STPS30150CW maintains identical electrical characteristics but uses TO-247-3 package instead of TO-220-3, suitable for applications requiring different thermal or mechanical mounting requirements.

Direct Manufacturer Substitute (Higher Current Rating, Same Package): MBR30150CT from Taiwan Semiconductor Corporation provides 30 A average rectified current per diode in TO-220-3 package, supporting higher current applications while maintaining 150 V reverse voltage and Schottky technology.

Similar Substitute (Lower Current Rating, Same Package): MBR10150CT-G1 from Diodes Incorporated provides 5 A average rectified current per diode in TO-220-3 package, suitable for lower current applications requiring identical voltage and package specifications.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level, and fast recovery Schottky technology.

Engineering Selection Recommendations

STPS30150CW Selection: Use this STMicroelectronics parametric equivalent when TO-247-3 package form factor is required for thermal management or mechanical mounting constraints. Electrical performance is identical to STPS30150CT with matching 15 A current rating and 920 mV forward voltage at 15 A. Both parts are ROHS3 compliant with active product status.

MBR30150CT Selection: Use this Taiwan Semiconductor Corporation substitute when application current requirements exceed 15 A, supporting up to 30 A average rectified current per diode. Maintains 150 V reverse voltage rating and TO-220-3 package compatibility. Forward voltage increases to 1.02 V at 30 A and reverse leakage increases to 100 µA at 150 V. Maximum junction temperature is 150°C compared to 175°C for STPS30150CT. ROHS3 compliant with active product status.

MBR10150CT-G1 Selection: Use this Diodes Incorporated substitute when application current requirements are 5 A or lower, reducing thermal dissipation requirements. Maintains 150 V reverse voltage rating and TO-220-3 package compatibility. Forward voltage is 890 mV at 5 A and reverse leakage is 50 µA at 150 V. Operating temperature range extends to -55°C minimum. ROHS3 compliant with active product status.

All substitute parts maintain Schottky technology, fast recovery speed characteristics, and through-hole mounting configuration. Selection should be based on specific current requirements, thermal management needs, and package form factor constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can STPS30150CW directly replace STPS30150CT in existing PCB designs?

A: STPS30150CW is electrically equivalent to STPS30150CT with identical 150 V reverse voltage, 15 A current rating, and 920 mV forward voltage. However, the package differs: STPS30150CW uses TO-247-3 while STPS30150CT uses TO-220-3. PCB footprint and mounting hole patterns are different, requiring PCB redesign. Both are through-hole devices with identical electrical performance.

Q: Is MBR30150CT a direct replacement for STPS30150CT?

A: MBR30150CT is not a direct replacement. While both use TO-220-3 package and maintain 150 V reverse voltage, MBR30150CT provides 30 A current rating compared to STPS30150CT's 15 A. Forward voltage increases to 1.02 V at 30 A, and reverse leakage increases to 100 µA. Maximum junction temperature is 150°C versus 175°C. Use MBR30150CT only when higher current capacity is required.

Q: What are the key differences between STPS30150CT and MBR10150CT-G1?

A: Both parts maintain 150 V reverse voltage and TO-220-3 package. MBR10150CT-G1 provides 5 A current rating compared to STPS30150CT's 15 A. Forward voltage is 890 mV at 5 A versus 920 mV at 15 A. Reverse leakage is 50 µA versus 6.5 µA. Operating temperature range extends to -55°C minimum. Use MBR10150CT-G1 for lower current applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. STPS30150CT, STPS30150CW, MBR30150CT, and MBR10150CT-G1 are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What determines whether a part can substitute for STPS30150CT?

A: Substitution is determined by maintaining Schottky diode technology, 1 pair common cathode configuration, 150 V reverse voltage rating, through-hole mounting, and compatible current rating for the application. Package form factor (TO-220-3 or TO-247-3) and current rating (5 A, 15 A, or 30 A) vary among substitutes based on application requirements.

Q: Can I use MBR30150CT in an application designed for STPS30150CT?

A: MBR30150CT can be used if the application can tolerate higher reverse leakage (100 µA versus 6.5 µA), slightly higher forward voltage at higher currents, and maximum junction temperature of 150°C instead of 175°C. The TO-220-3 package is identical, so PCB compatibility is maintained. Verify thermal and leakage specifications against application requirements.

Q: What is the difference between STPS30150CT and STPS30150CW in terms of thermal performance?

A: STPS30150CW uses TO-247-3 package which typically provides different thermal characteristics compared to STPS30150CT's TO-220-3 package. Electrical specifications are identical. Package selection should be based on PCB layout requirements and thermal management strategy of the specific application.
