VS-60CTQ035PBF Equivalent & Substitute Parts

Part Overview

The VS-60CTQ035PBF is a Schottky diode array in a 1 Pair Common Cathode configuration, rated for 35 V DC reverse voltage and 30 A average rectified current per diode. Manufactured by Vishay General Semiconductor - Diodes Division, this component is packaged in TO-220-3 through-hole format with fast recovery characteristics (≤500 ns).

The VS-60CTQ035PBF is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility within the allowed parameter ranges for this Schottky diode array category.

Substitute Part Grouping Explanation

Substitution of the VS-60CTQ035PBF is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory)
• Technology: Schottky (mandatory)
• Package / Case: TO-220-3 (mandatory)
• Mounting Type: Through Hole (mandatory)
• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 35 V
• Current - Average Rectified (Io) (per Diode): Must equal or exceed 30 A
• Speed: Fast Recovery ≤500 ns, >200 mA (Io) (mandatory)

Substitute Parts Identified:

Group 1: Direct Equivalent (Same Manufacturer)

• VS-60CTQ035-M3: Identical electrical specifications with active product status and tube packaging

Group 2: Cross-Manufacturer Substitute

• DSB30C30PB (IXYS): Meets core configuration and package requirements; voltage and current ratings differ within acceptable substitution parameters

Parameter Comparison

Engineering Selection Recommendations

VS-60CTQ035-M3 (Vishay): This part is the preferred direct substitute. It maintains identical electrical specifications to the VS-60CTQ035PBF, including 35 V reverse voltage rating, 30 A average rectified current, and 560 mV forward voltage at 30 A. The part is currently active with 801 units in stock. Packaging differs (tube versus original packaging), but the component itself is electrically and mechanically equivalent. RoHS3 compliance and MSL 1 rating are maintained. This substitute requires no circuit redesign.

DSB30C30PB (IXYS): This part is a cross-manufacturer substitute with reduced electrical ratings. The reverse voltage is 30 V (versus 35 V) and the average rectified current is 15 A (versus 30 A). The forward voltage is 510 mV at 15 A. This part is suitable only for applications where the circuit operates within the reduced voltage and current specifications. The part is currently active with 1387 units in stock. RoHS3 compliance and MSL 1 rating are maintained. Circuit redesign or derating analysis is required before selection.

Both substitute parts maintain the mandatory TO-220-3 package, through-hole mounting, 1 Pair Common Cathode configuration, Schottky technology, and fast recovery speed characteristics. All parts are RoHS3 compliant and carry MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can VS-60CTQ035-M3 be used as a direct replacement for VS-60CTQ035PBF?

A: Yes. The VS-60CTQ035-M3 is electrically and mechanically equivalent to the VS-60CTQ035PBF. Both parts share identical diode configuration, technology, voltage rating (35 V), current rating (30 A), forward voltage characteristics, and TO-220-3 package. The only difference is packaging format (tube). No circuit modifications are required.

Q: What are the limitations of using DSB30C30PB as a substitute?

A: The DSB30C30PB has reduced electrical ratings compared to the VS-60CTQ035PBF. The reverse voltage is 30 V instead of 35 V, and the average rectified current is 15 A instead of 30 A. This part is suitable only for circuits designed to operate within these lower specifications. Applications requiring the full 35 V / 30 A capability cannot use this substitute without circuit redesign or component derating.

Q: Are all substitute parts in the same package?

A: Yes. The VS-60CTQ035PBF, VS-60CTQ035-M3, and DSB30C30PB all use the TO-220-3 through-hole package. Pin configuration and mechanical dimensions are compatible for direct board-level substitution.

Q: Do the substitute parts maintain RoHS and compliance certifications?

A: Yes. Both VS-60CTQ035-M3 and DSB30C30PB are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance status.

Q: What is the difference between the main part and VS-60CTQ035-M3 in terms of product status?

A: The VS-60CTQ035PBF is discontinued at DiGi Electronics, while VS-60CTQ035-M3 is active with current inventory availability (801 units). For new designs and ongoing production, VS-60CTQ035-M3 is the recommended source.

Q: Can forward voltage differences affect circuit performance?

A: Forward voltage differences are specified at different current levels. The VS-60CTQ035PBF is rated at 560 mV @ 30 A, VS-60CTQ035-M3 at 720 mV @ 60 A, and DSB30C30PB at 510 mV @ 15 A. These specifications reflect the diodes' operating characteristics at their respective rated currents. Circuit designers must verify that forward voltage characteristics are acceptable for their specific application requirements.
