VS-20CTQ045PBF

Diode Arrays Overview

The VS-20CTQ045PBF is a center-tap Schottky rectifier featuring two independent diodes in a common cathode configuration. It provides a maximum average forward current of 20 A per leg and supports a maximum DC reverse voltage of 45 V. The device utilizes TO-220AB through-hole packaging with a base connected to the common cathode. It operates reliably up to a junction temperature of 175 °C, offering low forward voltage drop and high frequency operation capabilities.

Diode Arrays Procurement Notes

Verify component authenticity by checking markings against Vishay documentation. Confirm RoHS compliance status as indicated by the PbF suffix. Ensure thermal management aligns with datasheet ratings. Validate package dimensions match TO-220AB specifications before integration into circuit designs.

Diode Arrays Selection Notes

Select this component when a dual-diode common cathode arrangement is required for center-tapped applications. Consider the 45 V reverse voltage rating relative to peak circuit voltages. Evaluate thermal resistance requirements for the specific mounting environment. Verify that the 20 A per leg current capacity meets the load demands.

Diode Arrays Part Context

This part belongs to the VS-20CTQ... series of Schottky rectifiers from Vishay Semiconductors. The series includes variants with different voltage ratings such as 35 V and 40 V. All members share the same physical package and general electrical characteristics, differing primarily in their maximum reverse voltage capabilities.

Diode Arrays Replacement Considerations

Direct substitutes within the same family include the VS-20CTQ035PBF and VS-20CTQ040PBF. These alternatives offer identical packaging and current ratings but differ in maximum reverse voltage specifications.
