Single Diodes datasheet and documents for VS-31DQ03

VS-31DQ03

Single Diodes Overview

The VS-31DQ03 is a single-die Schottky rectifier from Vishay General Semiconductor - Diodes Division, housed in an axial DO-201AD (C-16) package. It features a maximum DC reverse voltage of 30 V and supports a maximum average forward current of 3.3 A under rectangular waveforms. The device exhibits a typical forward voltage drop of 0.57 V at 3 A and 25 °C, with a non-repetitive surge current capability of 450 A for 5 µs sine pulses. Operating junction temperatures range from -40 °C to 150 °C.

Single Diodes Feature Summary

Optimized for very low forward voltage drop with moderate leakage current
High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance
Guard ring design ensures enhanced ruggedness and long-term reliability
Halogen-free construction available via the -M3 suffix

Single Diodes Applications

Switching power supplies
Converters
Freewheeling diodes
Reverse battery protection

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. The standard part number denotes leaded terminations, while the -M3 suffix indicates lead-free, RoHS-compliant, and halogen-free specifications. Confirm that the required packaging format matches the bulk or tape-and-reel options listed in the datasheet ordering information table.

Single Diodes Selection Notes

Select this component when a low-profile axial leaded outline is required for high-frequency operation. Ensure the circuit design accommodates the specified thermal resistance values, particularly regarding the maximum allowable lead temperature versus average forward current. Validate that the peak reverse voltage rating aligns with the system's maximum working peak reverse voltage requirements.

Single Diodes Part Context

This component belongs to the 31DQ series of Schottky rectifiers manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings, such as the VS-31DQ04, which shares identical physical dimensions and current handling capabilities but offers a higher maximum DC reverse voltage of 40 V.
