The BSS225H6327FTSA1 is an n-channel enhancement mode SIPMOS small-signal transistor in a SOT89 surface-mount package. It features a drain-source breakdown voltage of 600 V and continuous drain current of 0.09 A at 25 °C. The device has a maximum on-state resistance of 45 Ω, gate threshold voltage ranging from 1.3 V to 2.3 V, and total gate charge up to 5.8 nC. It supports a power dissipation of 1 W, operates between -55 °C and 150 °C, and includes dv/dt rating of 6 kV/µs.
Verify the specific ordering suffix H6327 against official Infineon documentation to confirm packaging details and reel quantities. Ensure that the component meets the required AEC-Q101 qualification standards for your intended application environment. Cross-reference the datasheet revision with the manufacturing date code to ensure compatibility with your design specifications.
Select this component when a high-voltage n-channel MOSFET with logic-level input is required in a compact SOT89 package. Consider its low continuous current rating and relatively high on-resistance for small-signal or low-power switching tasks. Verify thermal management requirements given the 1 W power dissipation limit and junction-to-ambient thermal resistance.
This part belongs to Infineon's SIPMOS small-signal transistor series, designed for robust performance in demanding environments. The BSS225 variant specifically targets high-voltage applications requiring reliable switching characteristics within a standard surface-mount footprint suitable for automated assembly processes.
