Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS16150CG is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 150 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 8 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction (Max): 175°C or higher
• RoHS Status: ROHS3 Compliant

Substitute parts must satisfy all mandatory criteria to ensure functional and mechanical compatibility within the original application circuit. Variations in reverse leakage current and forward voltage drop are acceptable within the specified operating conditions, provided the part meets or exceeds the primary electrical ratings.

Engineering Selection Recommendations

STPS16170CG-TR (STMicroelectronics)

This substitute part is manufactured by the same original equipment manufacturer and maintains identical diode configuration, technology, and package specifications. The STPS16170CG-TR features a higher reverse voltage rating of 170 V compared to the 150 V specification of the STPS16150CG, providing enhanced voltage margin. Current rating remains at 8 A per diode, and forward voltage characteristics are identical. The part is classified as active product status, ensuring long-term availability and supply chain continuity. RoHS3 compliance and MSL 1 rating match the original specification. This part is suitable for direct substitution in applications where the 150 V reverse voltage requirement can accommodate the higher 170 V rating.

VS-20CTQ150STRRHM3 (Vishay General Semiconductor - Diodes Division)

This substitute part maintains the 150 V reverse voltage rating and TO-263-3 D2PAK package configuration of the original STPS16150CG. The VS-20CTQ150STRRHM3 provides an increased current rating of 10 A per diode, exceeding the 8 A specification. Forward voltage is lower at 880 mV @ 10 A, indicating improved efficiency characteristics. The part is classified as active product status with AEC-Q101 automotive qualification and operates across an extended temperature range of −55°C to 175°C. RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for direct substitution in applications requiring the original 150 V reverse voltage specification with the added benefit of higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can the STPS16170CG-TR be used as a direct replacement for the STPS16150CG?

A: The STPS16170CG-TR is electrically compatible with the STPS16150CG in applications where the circuit design accommodates a 170 V reverse voltage rating. Both parts share identical diode configuration, current rating, forward voltage characteristics, and package specifications. The higher voltage rating of the STPS16170CG-TR does not create incompatibility; it provides additional voltage margin. Compatibility depends on the specific circuit requirements and whether the 170 V rating is acceptable for the application.

Q: What are the differences between the STPS16150CG and VS-20CTQ150STRRHM3?

A: Both parts maintain the 150 V reverse voltage rating and identical package configuration. The primary differences are: (1) manufacturer—STMicroelectronics versus Vishay; (2) current rating—8 A versus 10 A per diode; (3) forward voltage—920 mV @ 8 A versus 880 mV @ 10 A; (4) reverse leakage—3 µA @ 150 V versus 25 µA @ 150 V; (5) temperature range—175°C maximum versus −55°C to 175°C; (6) automotive qualification—not specified for STPS16150CG versus AEC-Q101 for VS-20CTQ150STRRHM3. The VS-20CTQ150STRRHM3 offers higher current capacity and automotive-grade qualification.

Q: Are the substitute parts available in the same packaging format as the original STPS16150CG?

A: Both substitute parts use the TO-263-3 D2PAK surface mount package, which is mechanically and electrically compatible with the original STPS16150CG. The STPS16170CG-TR and VS-20CTQ150STRRHM3 are supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production applications. The physical footprint and pin configuration remain identical across all three parts.

Q: Why is the STPS16150CG classified as obsolete?

A: The STPS16150CG is classified as obsolete product status, indicating that the manufacturer has discontinued active production and support. The substitute parts STPS16170CG-TR and VS-20CTQ150STRRHM3 are both classified as active product status, ensuring continued availability, technical support, and supply chain reliability for new designs and production requirements.

Q: Do all three parts meet RoHS3 compliance requirements?

A: All three parts—STPS16150CG, STPS16170CG-TR, and VS-20CTQ150STRRHM3—are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity level rating. This ensures compatibility with lead-free soldering processes and compliance with environmental regulations across all substitute options.

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

A: Reverse leakage current values are 3 µA @ 150 V for STPS16150CG, 15 µA @ 170 V for STPS16170CG-TR, and 25 µA @ 150 V for VS-20CTQ150STRRHM3. These variations are within acceptable ranges for Schottky diode technology and do not affect functional compatibility in standard rectification applications. The leakage current specification is provided for applications requiring precise thermal or power dissipation calculations.
