SD103CWS-G3-18

Single Diodes Overview

The SD103CWS-G3-18 is a silicon Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 350 mA. The device utilizes the SOD-123 surface-mount package, offering low forward voltage drop and high switching efficiency. Key electrical parameters include a maximum DC blocking voltage of 20 V, a forward voltage of 600 mV at 200 mA, and a reverse leakage current of 5 µA at 10 V. It operates within a junction temperature range of -55°C to +125°C.

Single Diodes Feature Summary

• Utilizes silicon Schottky technology for low forward voltage and high switching efficiency
• Designed for surface-mount applications in compact SOD-123 packages
• Capable of withstanding operating junction temperatures up to 125°C

Single Diodes Applications

• DC-DC converters
• Free-wheeling diodes
• Polarity protection circuits
• Clamping diodes

Single Diodes Procurement Notes

Verify the specific suffix G3 confirms RoHS compliance and halogen-free status as per Vishay standards. Confirm the '18' suffix aligns with the required tape-and-reel packaging quantity for automated assembly lines. Cross-reference the manufacturer part number against the latest datasheet revision to ensure no design changes affect pinout or thermal characteristics.

Single Diodes Selection Notes

Select this component when a low-cost, small-footprint Schottky diode is required for 20 V reverse voltage applications. The 350 mA current rating suits low-power signal rectification and clamping tasks. Ensure the SOD-123 footprint matches the PCB layout constraints and that the thermal management supports the specified power dissipation limits under expected load conditions.

Single Diodes Part Context

This part belongs to the SD103xW series of Schottky barrier rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as 20 V (SD103CW), 30 V (SD103BW), and 40 V (SD103AW). All share similar physical dimensions and electrical characteristics regarding forward voltage and current handling, differing primarily in their breakdown voltage specifications.

Single Diodes Replacement Considerations

Direct substitutes include SD103AW-E3-18 (40 V) and SD103BW-E3-18 (30 V) from Vishay, provided the higher voltage ratings are acceptable. Other manufacturers offer equivalent SOD-123 Schottky diodes with matching 20 V/350 mA ratings, but verification of forward voltage and reverse leakage specs is required.
