The BSS169H6327XTSA1 is an N-channel depletion mode MOSFET from Infineon's SIPMOS series, housed in a PG-SOT-23 package. It features a drain-source breakdown voltage of 100 V and a continuous drain current of 0.17 A at 25 °C. The device exhibits a maximum on-state resistance of 12 Ω at VGS=0 V and a typical gate threshold voltage of -2.2 V. It supports a power dissipation of 0.36 W and operates within a temperature range of -55 °C to +150 °C.
Verify the specific VGS(th) band letter printed on the reel label matches the design requirements, as the component is sorted into bands. Confirm that the PG-SOT-23 footprint aligns with the PCB layout. Ensure the depletion mode characteristic is compatible with the intended circuit logic levels.
Select this component for designs requiring normally-on behavior or high dv/dt immunity. The low gate charge facilitates fast switching speeds. Consider the thermal resistance of 250 K/W when determining heat dissipation needs in minimal footprints. Verify that the negative threshold voltage suits the control interface.
This part belongs to the BSS169 family of SIPMOS small-signal transistors. It utilizes silicon technology and is manufactured by Infineon Technologies. The component is designed for surface mount installation and is compliant with RoHS standards and halogen-free requirements.
No public confirmed substitute part numbers are documented.
