HS1GAL

Single Diodes Overview

The HS1GAL is a standard recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1 A. The device utilizes a thin SMA (DO-221AC) surface-mount package with flat leads. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 400 V, a typical forward voltage of 1.3 V at 1 A, and a junction capacitance of 17 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm that the requested variant matches the required lead time and availability status. Ensure compliance with RoHS directives if applicable to your assembly process. Cross-reference the manufacturer part number with distributor listings to validate authenticity and sourcing channels before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a standard recovery speed is sufficient for the application frequency. The 1 A current rating and 400 V blocking voltage define the operational limits. Consider the thin SMA package dimensions for PCB layout constraints. Evaluate the 1.3 V forward voltage drop for efficiency requirements in low-voltage systems compared to Schottky alternatives.

Single Diodes Part Context

This component belongs to the HS1G series of single standard recovery rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling capabilities. The HS1GAL specifically denotes the 400 V variant within this lineup, designed for cost-effective solutions in consumer electronics and industrial control equipment requiring reliable unidirectional current flow.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent parts with matching 1 A current and 400 V voltage ratings. Verify pinout compatibility and package footprint alignment before replacing the original component. Ensure replacement devices meet the same thermal and electrical performance standards.
