Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS10150CG is determined by strict equivalence across the following critical parameters:

• Diode Configuration: 1 Pair Common Cathode (electrical topology must match)
• Technology: Schottky (switching characteristics and forward voltage behavior)
• Voltage - DC Reverse (Vr) (Max): 150 V (voltage rating must be equal or greater)
• Current - Average Rectified (Io) (per Diode): 5 A (current handling capacity must be equal or greater)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mechanical and thermal interface compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)

Substitute parts are grouped into two categories:

Category 1: Direct Manufacturer Equivalent (Same Manufacturer) STPS10150CG-TR is the active production variant of the STPS10150CG base product number, maintaining identical electrical specifications and packaging.

Category 2: Cross-Manufacturer Equivalents 10CTQ150S (Vishay) and MBRB10150CT (Diodes Incorporated) meet all critical electrical and mechanical parameters while offering alternative sourcing and product status options.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: STPS10150CG-TR

STPS10150CG-TR is the preferred substitute for STPS10150CG. Both parts share identical electrical specifications, packaging, and are manufactured by STMicroelectronics. STPS10150CG-TR maintains active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. This substitution requires no circuit redesign or thermal management recalculation.

Secondary Recommendation: MBRB10150CT

MBRB10150CT (Diodes Incorporated) is an active product meeting all critical electrical and mechanical parameters. This part carries AEC-Q101 automotive qualification and ROHS3 compliance. Forward voltage is 890 mV @ 5 A, which is 30 mV lower than STPS10150CG, resulting in reduced power dissipation. Reverse leakage current is 50 µA @ 150 V, compared to 2 µA for STPS10150CG. This part is suitable for applications where lower forward voltage drop is beneficial and reverse leakage tolerance permits.

Alternative Option: 10CTQ150S

10CTQ150S (Vishay) meets all critical electrical and mechanical parameters but carries obsolete product status and RoHS non-compliance. This part is not recommended for new designs or long-term production applications. Forward voltage is 930 mV @ 5 A, and reverse leakage is 50 µA @ 150 V. Use only when existing inventory must be consumed or legacy system support is required.

Frequently Asked Questions (FAQ)

Q: Can STPS10150CG-TR be used as a direct replacement for STPS10150CG?

A: Yes. STPS10150CG-TR is the active production equivalent of STPS10150CG. Both parts share identical electrical specifications, packaging (TO-263-3 D2PAK), and thermal characteristics. The only difference is product status (active vs. obsolete) and packaging format (Cut Tape & Digi-Reel vs. standard). No circuit modifications are required.

Q: What is the difference between STPS10150CG and MBRB10150CT?

A: Both parts are 150 V, 5 A Schottky diode arrays in TO-263-3 D2PAK packages. Key differences are: (1) Forward voltage: MBRB10150CT is 890 mV @ 5 A versus 920 mV for STPS10150CG, resulting in approximately 30 mV lower drop; (2) Reverse leakage: MBRB10150CT is 50 µA @ 150 V versus 2 µA for STPS10150CG; (3) MBRB10150CT carries AEC-Q101 automotive qualification. Both are ROHS3 compliant and active products.

Q: Why is 10CTQ150S not recommended as a primary substitute?

A: 10CTQ150S is classified as obsolete and RoHS non-compliant. While it meets electrical and mechanical requirements, its discontinued status creates long-term supply risk. It is suitable only for legacy system maintenance or inventory consumption scenarios.

Q: Are there thermal management differences between these substitutes?

A: All four parts share identical maximum junction temperature (175°C) and TO-263-3 D2PAK packaging, which provides equivalent thermal interface characteristics. Thermal performance differences arise from forward voltage variations: MBRB10150CT (890 mV) generates less heat than STPS10150CG (920 mV) at 5 A operation.

Q: Can these parts be used interchangeably in automotive applications?

A: MBRB10150CT carries AEC-Q101 automotive qualification. STPS10150CG, STPS10150CG-TR, and 10CTQ150S do not carry automotive qualification. For automotive applications, MBRB10150CT is the appropriate selection.

Q: What is the significance of the "-TR" suffix in STPS10150CG-TR?

A: The "-TR" suffix indicates Cut Tape (CT) and Digi-Reel packaging format, which is a standard tape-and-reel configuration for automated assembly. The electrical specifications and die are identical to STPS10150CG. The suffix reflects packaging and distribution format only.

Q: Are all these parts RoHS compliant?

A: STPS10150CG, STPS10150CG-TR, and MBRB10150CT are ROHS3 compliant. 10CTQ150S is RoHS non-compliant. For applications requiring RoHS compliance, use STPS10150CG-TR or MBRB10150CT.
