VS-21DQ04

Single Diodes Overview

The VS-21DQ04 is a single-die Schottky rectifier in the DO-204AL (DO-41) axial leaded package. It features a maximum average forward current of 2 A and a maximum repetitive peak reverse voltage of 40 V. The device exhibits a typical forward voltage drop of 0.5 V at 2 A and 125 °C, with a maximum non-repetitive surge current rating of 420 A. Operating junction temperatures range from -40 °C to +150 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Suffixes such as TR or TB indicate distinct packaging formats like tape and reel or ammo box. Confirm RoHS compliance status and halogen-free requirements if applicable to the design specifications. Ensure the selected variant matches the required quantity per packaging unit.

Single Diodes Selection Notes

Select this component based on the 2 A average forward current and 40 V reverse voltage ratings. Evaluate thermal management requirements using the specified thermal resistance values for the intended duty cycle. Consider the forward voltage drop characteristics at expected operating temperatures to ensure efficiency targets are met within the circuit design constraints.
