HS1DFS

Single Diodes Overview

The HS1DFS is a standard fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1 A. The device utilizes a glass passivated chip junction for enhanced reliability. It is housed in the SOD-128 surface mount package, designed for automated assembly processes. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 200 V and a typical reverse recovery time of 50 ns. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Glass passivated chip junction construction ensures high reliability and stability under various operating conditions.
• Designed specifically for automatic mounting and surface mount applications using the compact SOD-128 package.
• Fast recovery characteristics suitable for general-purpose rectification and switching applications.

Single Diodes Applications

• General purpose rectification in electronic circuits
• Reverse polarity protection
• Free-wheeling diodes in low-frequency switching power supplies

Single Diodes Procurement Notes

Verify the manufacturer part number HS1DFS against official Taiwan Semiconductor documentation to confirm authenticity. Ensure compliance with RoHS3 and REACH regulations as specified in the datasheet. Check for specific ordering suffixes if required, noting that packaging variations such as tape and reel or cut tape may exist but do not alter the component's electrical function. Confirm moisture sensitivity level 1 status for storage and handling requirements.

Single Diodes Selection Notes

Select the HS1DFS when a 200 V reverse voltage rating and 1 A continuous current capacity are required in a small surface mount footprint. Consider the 50 ns reverse recovery time for applications requiring faster switching than standard rectifiers but where ultra-fast specifications are unnecessary. Evaluate the SOD-128 package dimensions against PCB layout constraints compared to other SOD-123 or SOD-323 variants.

Single Diodes Part Context

The HS1DFS belongs to the HS1D series of fast recovery rectifiers from Taiwan Semiconductor. This series includes various voltage ratings ranging from 50 V to 1000 V, all sharing similar physical packaging and basic performance profiles. The 'FS' suffix typically denotes the specific package type and speed class within the product line, distinguishing it from other variants like HS1G or HS1J which offer different voltage capabilities.
