VS-80SQ045

Single Diodes Overview

The VS-80SQ045 is an axial leaded Schottky rectifier from Vishay General Semiconductor, housed in a DO-204AR package. It features a maximum average forward current of 8 A and a peak repetitive reverse voltage of 45 V. The device supports junction temperatures up to 175 °C and exhibits a low forward voltage drop of 0.44 V at 8 A and 125 °C. It offers high surge capability with a non-repetitive peak forward surge current of 2400 A for a 5 µs sine pulse.

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number indicates standard packaging, while suffixes like -M3 denote halogen-free and RoHS compliance. Confirm whether bulk or tape-and-reel quantities are required, as these affect the minimum order quantity and packaging description. Ensure the component meets the environmental standards necessary for the intended application.

Single Diodes Selection Notes

Select this component for applications requiring high-frequency operation and low reverse leakage at high temperatures. The 45 V rating suits low-voltage DC circuits. Consider the thermal resistance and allowable case temperature curves for heat dissipation planning. Verify that the 8 A continuous current rating aligns with the circuit's load requirements under expected operating conditions.

Single Diodes Part Context

This component belongs to the VS-80SQ... series of Schottky rectifiers designed for general-purpose rectification. The series includes variants with different voltage ratings such as 30 V, 35 V, and 40 V. All share the same 8 A current rating and DO-204AR axial leaded package, allowing for pin-compatible design flexibility across different voltage requirements within the same product family.

Single Diodes Replacement Considerations

Check datasheets for alternative Schottky rectifiers with matching 8 A current and 45 V voltage ratings. Ensure the replacement device fits the DO-204AR package and maintains similar thermal characteristics. Verify that any substitute also supports the required 175 °C junction temperature if high-temperature operation is critical.
