HS2KALH

Single Diodes Overview

The HS2KALH is a standard rectifier diode manufactured by Taiwan Semiconductor Corporation, housed in a thin SMA (DO-221AC) surface-mount package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 2 A. The device exhibits a typical junction-to-lead thermal resistance of 17 °C/W and operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Thin SMA surface-mount packaging for compact board integration
• High-efficiency rectification with low thermal resistance
• Robust reverse voltage capability up to 800 V

Single Diodes Applications

• General-purpose rectification in power supplies
• Freewheeling diodes in DC-DC converters
• Reverse polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm it denotes the thin SMA package variant rather than a different casing or tape-and-reel specification. Ensure the 800V rating aligns with system requirements before procurement.

Single Diodes Selection Notes

Select this component when a 2A current rating and 800V blocking voltage are required in a space-constrained surface-mount application. Compare thermal performance metrics against alternative packages if high-power dissipation is anticipated in the target design.

Single Diodes Part Context

This part belongs to the HS2_ALH series of high-efficiency surface mount diodes from Taiwan Semiconductor. The series offers various voltage ratings ranging from 200V to 1000V while maintaining a consistent 2A current capacity across variants.

Single Diodes Replacement Considerations

Check for direct substitutes within the same HS2 series family, such as HS2DALH or HS2MALH, which share the 2A rating but differ in reverse voltage specifications. Verify pinout compatibility and thermal characteristics before substitution.
