The BSS225H6327XTSA1 is an n-channel enhancement mode SIPMOS small-signal transistor in a SOT-89 package. It features a maximum drain-source voltage of 600 V and a continuous drain current of 0.09 A at 25 °C. The device has a maximum on-state resistance of 45 Ω and a power dissipation rating of 1 W. It operates within a temperature range of -55 °C to 150 °C and includes a reverse diode with a forward voltage of 1.2 V.
Verify the specific ordering suffix H6327XTSA1 against official Infineon documentation to confirm tape and reel packaging quantities and marking details. Ensure that application environments include protective lacquer if external creeping currents are a concern, as specified in the datasheet notes regarding package contamination.
Select this component when a robust n-channel MOSFET with high breakdown voltage is required in a compact surface-mount form factor. Consider the thermal resistance of 125 K/W and the low continuous current limit of 0.09 A for appropriate heat dissipation planning. Verify that the logic-level gate threshold aligns with the driving circuit's output voltage capabilities.
This part belongs to Infineon's SIPMOS series of small-signal transistors. It utilizes silicon technology optimized for high-voltage performance in small packages. The device integrates standard N-channel enhancement mode characteristics with automotive qualification standards, distinguishing it from general-purpose industrial counterparts.
Consult official Infineon cross-reference documents for verified substitutes. Do not assume functional equivalence based solely on pinout or voltage ratings without verifying dynamic parameters and package dimensions.
