Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

Select VS-16CTQ080S-M3, VS-16CTQ080STRL-M3, VS-16CTQ080STRR-M3, or their automotive-qualified variants (VS-16CTQ080STRLHM3, VS-16CTQ080STRRHM3) when the application requires identical electrical performance to the 16CTQ080S. These Vishay parts maintain 100% parameter compatibility and are available in active product status with RoHS3 compliance.

VS-16CTQ080S-M3 (Tube packaging): Suitable for lower-volume applications and manual assembly processes.
VS-16CTQ080STRL-M3 (Tape & Reel): Standard choice for automated assembly and production environments.
VS-16CTQ080STRLHM3 and VS-16CTQ080STRRHM3 (Automotive-qualified, AEC-Q101): Required for automotive applications or systems requiring automotive-grade component certification.

For Enhanced Performance (Manufacturer Recommended):

Select STPS16H100CG-TR (STMicroelectronics) when the application circuit can accommodate a higher voltage rating (100 V vs. 80 V). This part provides improved reverse leakage characteristics (3.6 µA @ 100 V vs. 550 µA @ 80 V) and maintains identical current rating, package format, and diode configuration. The higher voltage rating provides additional design margin for transient protection.

Compliance Considerations:

All active substitute parts are RoHS3 compliant, addressing regulatory requirements not met by the obsolete 16CTQ080S. Automotive applications must specify AEC-Q101 qualified variants (VS-16CTQ080STRLHM3 or VS-16CTQ080STRRHM3).

Frequently Asked Questions (FAQ)

Q: Can VS-16CTQ080S-M3 be used as a direct replacement for 16CTQ080S?

A: Yes. VS-16CTQ080S-M3 is a parametric equivalent with identical electrical specifications (80 V, 8 A, Schottky technology, 1 Pair Common Cathode configuration) and mechanical compatibility (TO-263-3, D2PAK package). The primary difference is product status (Active vs. Obsolete) and packaging format (Tube vs. Bulk). RoHS3 compliance is an additional benefit.

Q: What is the difference between VS-16CTQ080STRL-M3 and VS-16CTQ080S-M3?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format: VS-16CTQ080STRL-M3 is supplied in Tape & Reel (TR) format for automated assembly, while VS-16CTQ080S-M3 is supplied in Tube format for manual assembly or lower-volume applications.

Q: When should I use the automotive-qualified variants (VS-16CTQ080STRLHM3 or VS-16CTQ080STRRHM3)?

A: Use automotive-qualified variants when the application is for automotive systems or when AEC-Q101 certification is required by design specifications or customer requirements. These parts maintain identical electrical and mechanical parameters to the standard variants.

Q: Can STPS16H100CG-TR replace 16CTQ080S in all applications?

A: STPS16H100CG-TR is electrically compatible for applications designed for 80 V operation, as it is rated for 100 V (higher voltage margin). The part maintains identical current rating (8 A), diode configuration (1 Pair Common Cathode), technology (Schottky), and package format (TO-263-3, D2PAK). However, forward voltage is slightly higher (770 mV vs. 720 mV @ 8 A), which may affect power dissipation calculations in high-current applications.

Q: What is the significance of the "HM3" suffix in part numbers VS-16CTQ080STRLHM3 and VS-16CTQ080STRRHM3?

A: The "HM3" suffix indicates automotive-grade qualification (AEC-Q101) and Tape & Reel packaging with specific handling requirements. These parts are qualified for automotive applications and meet enhanced reliability and traceability standards.

Q: Are all substitute parts compatible with the TO-263-3 (D2PAK) footprint?

A: Yes. All substitute parts listed are packaged in TO-263-3, D2PAK (2 Leads + Tab), TO-263AB format and are mechanically compatible with existing PCB layouts designed for 16CTQ080S.

Q: What is the difference in reverse leakage between 16CTQ080S and STPS16H100CG-TR?

A: The 16CTQ080S exhibits 550 µA reverse leakage @ 80 V, while STPS16H100CG-TR exhibits 3.6 µA reverse leakage @ 100 V. The STMicroelectronics part demonstrates significantly lower leakage current, which may reduce standby power consumption in applications sensitive to reverse leakage.

Q: Is the 16CTQ080S still available for purchase?

A: The 16CTQ080S is classified as obsolete. However, 883 pieces are currently in stock. For new designs or long-term supply assurance, selection of active substitute parts (VS-16CTQ080S-M3, VS-16CTQ080STRL-M3, or STPS16H100CG-TR) is recommended.
