BAV20WS-E3-18

Overview

The BAV20WS-E3-18 is a single silicon rectifier diode from Vishay General Semiconductor. It features a maximum repetitive reverse voltage of 250 V and an average forward current rating of 625 mA, with a surge forward current capability of 1 A. The device is housed in a compact SOD-80 surface-mount package with two terminals. It operates within a junction temperature range of -55 °C to +150 °C and exhibits a maximum forward voltage drop of 1.25 V at 200 mA. The component is lead-free, RoHS compliant, and classified as a standard speed diode.

Feature Summary

• High-voltage blocking capability suitable for general-purpose switching applications
• Compact surface-mount SOD-80 package design for space-constrained layouts
• Wide operating junction temperature range supporting diverse thermal environments

Applications

• General-purpose signal switching circuits
• Protection against reverse polarity in low-current DC lines
• Clamping and snubber applications in consumer electronics

Procurement Notes

Verify the specific suffix E3-18 corresponds to the required tape-and-reel packaging configuration. Confirm that the 250 V reverse voltage rating aligns with the peak inverse voltage requirements of the target circuit. Ensure compatibility with the SOD-80 footprint during PCB layout finalization. Check for any updated environmental compliance declarations prior to integration.

Selection Notes

Select this component when a high-voltage standard diode is needed in a minimal footprint. The 250 V rating provides significant margin over lower-voltage alternatives like the BAV20. Consider the 625 mA current limit for load requirements. The SOD-80 package offers a smaller profile compared to axial leads, making it ideal for automated assembly processes in dense electronic assemblies.

Part Context

This part belongs to the BAVxxWS series of glass-passivated silicon junction diodes manufactured by Vishay. The series is designed for high-speed switching and general rectification tasks. The WS suffix typically denotes the specific small-outline surface-mount package variant, distinguishing it from axial or other package styles within the broader BAV product family.
