BAT43WS-E3-18

Single Diodes Overview

The BAT43WS-E3-18 is a single Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage (Vrrm) of 30 V and an average forward rectified current (Io) of 200 mA. The device exhibits a low forward voltage drop with a maximum value of 1 V at specified conditions, ensuring efficient power conversion. Reverse leakage current is limited to 500 nA at 25 V. Key electrical parameters include a peak non-repetitive forward surge current (Ifsm) of 4 A and a typical reverse recovery time (trr) of 5 ns. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix 'E3' confirms lead-free termination compliant with RoHS directives. Confirm the package designation matches SOD-323 dimensions for PCB footprint compatibility. Ensure the ordering code includes the correct tape and reel quantity if automated placement is required. Cross-reference the manufacturer part number against the latest datasheet revision to confirm no design changes have occurred since the initial specification.

Single Diodes Selection Notes

Select this component when circuit requirements demand a low forward voltage drop combined with rapid switching speeds. The 30 V reverse voltage rating provides adequate margin for low-voltage systems while maintaining robustness against transient spikes. Consider the 200 mA current limit for small-signal applications rather than high-power loads. The SOD-323 package offers space-saving advantages for dense board layouts compared to larger through-hole alternatives.

Single Diodes Part Context

This device belongs to the BAT43W series of Schottky diodes from Vishay. The series is characterized by its use in low-voltage, high-frequency applications where speed and efficiency are critical. The 'W' suffix typically denotes the specific plastic encapsulate type used for surface mount reliability. This family is widely utilized in consumer electronics and telecommunications equipment requiring compact, high-performance rectification solutions.

Single Diodes Replacement Considerations

Direct substitutes may include other Vishay Schottky diodes in the SOD-323 package with similar voltage and current ratings, such as the BAT43S or BAT46 variants, provided their reverse voltage and current specifications align with the circuit design requirements. Verify pinout compatibility and thermal performance before substitution.
