VS-12CTQ035SPBF Equivalent & Substitute Parts

Part Overview

The VS-12CTQ035SPBF is a Schottky diode array manufactured by Vishay General Semiconductor - Diodes Division. This component features a 1 Pair Common Cathode configuration rated for 35 V DC reverse voltage and 6 A average rectified current per diode. The device is housed in a TO-263-3 (D2PAK) surface mount package with two leads and a tab.

The VS-12CTQ035SPBF is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from the same manufacturer with identical electrical and mechanical specifications but different packaging formats and active product status.

Substitute Part Grouping Explanation

Substitution of the VS-12CTQ035SPBF is determined by electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 35 V
Current - Average Rectified (Io) (per Diode): 6 A
Voltage - Forward (Vf) (Max) @ If: 600 mV @ 6 A
Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
Current - Reverse Leakage @ Vr: 800 µA @ 35 V
Operating Temperature - Junction: -55°C ~ 175°C
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB

The substitute parts differ only in packaging format (Tube or Tape & Reel) and product status (Active versus Discontinued). These differences do not affect electrical performance or mechanical compatibility in circuit applications.

Engineering Selection Recommendations

The VS-12CTQ035SPBF is discontinued and should be replaced with an active equivalent part. All three substitute parts—VS-12CTQ035S-M3, VS-12CTQ035STRL-M3, and VS-12CTQ035STRR-M3—provide identical electrical performance and mechanical compatibility.

Selection between substitute parts depends on procurement and assembly requirements:

VS-12CTQ035S-M3 is supplied in Tube packaging format, suitable for lower-volume applications or manual assembly processes.

VS-12CTQ035STRL-M3 and VS-12CTQ035STRR-M3 are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly operations. Both variants maintain identical electrical specifications and differ only in reel configuration.

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and identical thermal operating range (-55°C ~ 175°C junction temperature).

Frequently Asked Questions (FAQ)

Q: Can VS-12CTQ035S-M3, VS-12CTQ035STRL-M3, and VS-12CTQ035STRR-M3 be used interchangeably with VS-12CTQ035SPBF in circuit applications?

A: Yes. All substitute parts share identical electrical specifications including reverse voltage rating (35 V), average rectified current (6 A per diode), forward voltage drop (600 mV @ 6 A), and thermal operating range (-55°C ~ 175°C). The TO-263-3 D2PAK package footprint is identical across all variants.

Q: What is the difference between the three substitute parts?

A: The substitute parts differ only in packaging format and product status. VS-12CTQ035S-M3 is supplied in Tube format. VS-12CTQ035STRL-M3 and VS-12CTQ035STRR-M3 are supplied in Tape & Reel (TR) format. All three are currently active products from Vishay.

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel packaging formats do not affect the electrical characteristics or performance of the diode array. Packaging format selection is determined by assembly process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. VS-12CTQ035S-M3, VS-12CTQ035STRL-M3, and VS-12CTQ035STRR-M3 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the reverse leakage current specification?

A: The reverse leakage current is 800 µA @ 35 V for all parts, including the original VS-12CTQ035SPBF and all substitute variants.

Q: Can these parts be used in high-temperature applications?

A: Yes. All parts are rated for junction temperatures from -55°C to 175°C, supporting operation across extended thermal ranges.
