Engineering Selection Recommendations

Parametric Equivalent (Same Current Rating):

The VB30150C-M3/8W is a parametric equivalent to the VB30150C-E3/8W. Both parts are manufactured by Vishay, share identical electrical specifications, and are housed in the same TO-263-3 D2PAK package. Both maintain Active product status and ROHS3 compliance. The primary distinction is packaging format (both Tape & Reel). This part is suitable for direct substitution in applications requiring 15 A rated current.

Current-Rated Alternatives (STMicroelectronics):

STMicroelectronics STPS series parts provide alternatives across multiple current ratings while maintaining the 150 V reverse voltage specification and TO-263-3 D2PAK package format:

STPS10150CG-TR (5 A): Suitable only for applications with maximum current requirements of 5 A or less. Not suitable for the full 15 A rating of the VB30150C-E3/8W.
STPS20150CG-TR (10 A): Suitable for applications with maximum current requirements of 10 A or less. Not suitable for the full 15 A rating of the VB30150C-E3/8W.
STPS40150CG and STPS40150CG-TR (20 A): Suitable for applications requiring up to 20 A. These parts exceed the 15 A rating of the VB30150C-E3/8W and are compatible with designs requiring the original part's current capacity. The STPS40150CG-TR variant in Cut Tape & Digi-Reel® format provides packaging flexibility.

All STMicroelectronics alternatives maintain ROHS3 compliance, unlimited MSL rating, and Fast Recovery speed specifications. Operating temperature range extends to 175°C (Max) compared to 150°C for the Vishay part.

Frequently Asked Questions (FAQ)

Q: Can the STPS10150CG-TR or STPS20150CG-TR be used as direct replacements for the VB30150C-E3/8W?

A: No. The STPS10150CG-TR is rated for 5 A maximum current and the STPS20150CG-TR is rated for 10 A maximum current. The VB30150C-E3/8W is rated for 15 A. Using a lower-rated part in an application designed for 15 A will result in component failure or thermal stress. These parts are suitable only for applications with lower current requirements.

Q: Can the STPS40150CG-TR be used in place of the VB30150C-E3/8W?

A: Yes. The STPS40150CG-TR maintains the same 150 V reverse voltage specification, 1 Pair Common Cathode configuration, Schottky technology, and TO-263-3 D2PAK package format. The 20 A current rating exceeds the 15 A requirement of the VB30150C-E3/8W, making it suitable for direct substitution. The extended operating temperature range to 175°C provides additional thermal margin.

Q: What is the difference between STPS40150CG and STPS40150CG-TR?

A: Both parts are electrically identical with 20 A current rating and 150 V reverse voltage. The primary difference is packaging format. STPS40150CG is supplied in Tube packaging, while STPS40150CG-TR is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly line requirements and component handling procedures.

Q: Are there differences in forward voltage between the VB30150C-E3/8W and STMicroelectronics alternatives?

A: Yes. The VB30150C-E3/8W exhibits a maximum forward voltage of 1.36 V at 15 A. STMicroelectronics parts (STPS series) show 920 mV at their respective current ratings. Lower forward voltage reduces power dissipation and heat generation. This difference must be considered in thermal design calculations for applications with tight thermal budgets.

Q: Is the VB30150C-M3/8W identical to the VB30150C-E3/8W?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications, package format, and compliance certifications. Both are rated for 15 A current and 150 V reverse voltage. The parts are interchangeable for all applications.

Q: What is the significance of the reverse leakage current differences between parts?

A: Reverse leakage current affects power consumption during reverse bias operation. The VB30150C-E3/8W exhibits 200 µA leakage at 150 V, while STMicroelectronics parts show lower leakage (2 µA to 8 µA depending on current rating). Lower leakage reduces standby power consumption and heat generation. This parameter is critical in low-power or battery-powered applications.

Q: Can parts with lower current ratings be used if the application does not require full 15 A capacity?

A: Yes, but only if the actual application current requirement is confirmed to be below the substitute part's rating. For example, if an application requires only 8 A maximum, the STPS20150CG-TR (10 A rated) is suitable. However, the application must be thoroughly analyzed to ensure peak current demands do not exceed the substitute part's specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—VB30150C-E3/8W, VB30150C-M3/8W, STPS10150CG-TR, STPS20150CG-TR, STPS40150CG, and STPS40150CG-TR—maintain ROHS3 compliance and are suitable for applications with RoHS requirements.
