BAT43WS-G3-18

Single Diodes Overview

The BAT43WS-G3-18 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 utilizes a surface-mount SOD-323 (SC-76) package with two pins. Key electrical parameters include a maximum DC reverse leakage current of 500 nA at 25 V, a typical reverse recovery time (trr) of 5 ns, and a junction capacitance of 7 pF at 1 V and 1 MHz. The component operates within a temperature range of -55°C to +125°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix G3-18 against the manufacturer's latest datasheet to confirm lead-free status and packaging format. Ensure compatibility with automated pick-and-place equipment regarding the SOD-323 footprint dimensions. Cross-reference the part number with authorized distributors to confirm current production status and availability constraints.

Single Diodes Selection Notes

Select this component when a compact Schottky diode with low reverse recovery time is required for space-constrained designs. The 30 V rating suits low-voltage DC systems, while the 200 mA current capacity supports moderate load requirements. Consider the SOD-323 package size relative to available PCB real estate and thermal dissipation needs.

Single Diodes Part Context

This part belongs to the BAT43W series of small-signal Schottky diodes from Vishay. The series is characterized by its use in high-speed switching applications where minimal power loss and fast response times are critical. The W suffix typically denotes the specific plastic case outline and termination finish specifications defined by the manufacturer.

Single Diodes Replacement Considerations

Direct substitutes include BAT43W-E3-18 and BAT43WS-HG3_A-18, which share identical electrical characteristics and package dimensions. Verify pinout orientation and thermal performance before implementing any alternative part numbers.
