ASD101CWS-HF

Overview

The ASD101CWS-HF is a small signal Schottky diode manufactured by Comchip Technology. It features a 40V reverse voltage rating and a 70mA forward current capability. The device utilizes an SOD-323 surface-mount package with tin-plated leads for solderability. Marking on the component body is designated as 'S3', with the cathode end indicated by a line. This component is designed for applications requiring fast switching and low forward voltage drop.

Feature Summary

• Schottky barrier construction for fast switching performance
• Low forward voltage drop characteristics
• Tin-plated leads compliant with J-STD-002 and JESD22-B102 standards

Applications

• General purpose rectification in low voltage circuits
• Clamping and protection of sensitive semiconductor junctions
• Free-wheeling diodes in low current DC-DC converters

Procurement Notes

Verify the specific suffix 'CWS' against the manufacturer's official datasheet to confirm the exact electrical parameters, particularly the 40V reverse voltage rating. Ensure the SOD-323 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the latest product compliance documentation provided by Comchip Technology before integration.

Selection Notes

Select this component when a compact SOD-323 footprint is required for low-current Schottky rectification. The 40V rating suits low-voltage logic and power rails. Compare the 70mA current limit against circuit peak requirements. Verify thermal management needs are minimal due to the small package size and low power dissipation profile inherent to this current level.

Part Context

This part belongs to the ASD101xWS-HF series from Comchip Technology, which includes variants like ASD101AWS-HF and ASD101CWS-HF. These devices share the SOD-323 molded plastic case and similar marking conventions. The series is characterized by small signal Schottky properties, distinguishing it from higher-power TVS or standard rectifier lines offered by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers for ASD101CWS-HF were not found in the provided source material. Cross-referencing with other 40V 70mA SOD-323 Schottky diodes requires independent verification of pinout and electrical tolerances.
