BAT54WS-E3-18

Single Diodes Overview

The BAT54WS-E3-18 is a single Schottky barrier rectifier manufactured by Vishay Semiconductors. It utilizes a silicon planar structure housed in an SOD-323 surface-mount package. The device is characterized by a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current rating of 200 mA. Key electrical specifications include a low forward voltage drop of 800 mV at 100 mA and a maximum reverse leakage current of 500 nA at 25 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Features very low turn-on voltage for efficient signal detection and power management
• Incorporates a PN junction guard ring to protect against excessive voltage stress such as electrostatic discharges
• Designed for fast switching applications with minimal reverse recovery time

Single Diodes Applications

• High-speed switching circuits
• Signal detection and mixing
• Power management systems requiring low forward voltage drop

Single Diodes Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance and halogen-free status according to Vishay standards. Confirm the '18' suffix corresponds to the standard tape-and-reel packaging format. Ensure the ordering part number matches the exact SOD-323 configuration required for the target PCB footprint. Cross-reference the manufacturer datasheet for any recent changes in material categorization or environmental declarations.

Single Diodes Selection Notes

Select this component when a single Schottky diode with a 30 V reverse voltage rating is required in a compact SOD-323 package. It is suitable for designs prioritizing low forward voltage characteristics and high switching speeds. Consider the 200 mA average current limit and the thermal constraints of the small surface-mount package during circuit design.

Single Diodes Part Context

This component belongs to the BAT54 series of small-signal Schottky diodes from Vishay. The 'W' designation typically indicates the SOD-323 surface-mount package variant, distinguishing it from other package options like DO-35 or SOD-80. The E3 suffix denotes lead (Pb)-free construction compliant with European Union directives.
