Single FETs, MOSFETs datasheet and documents for BSS138W

BSS138W

Single FETs, MOSFETs Overview

The BSS138W is an N-channel small signal MOSFET housed in a SOT-323 package. It features a maximum drain-source voltage of 60 V and a continuous drain current of 0.28 A at 25°C, with a pulsed current capability of 1.12 A. The device exhibits a typical gate charge of 1 nC at 4.5 V and a maximum on-resistance of 6000 mΩ at 4.5 V. Input capacitance is specified at 32 pF, while output capacitance is 7.2 pF. Thermal resistance from junction to ambient is rated at 250 K/W. The component operates within a temperature range of -55°C to +150°C.

Single FETs, MOSFETs Procurement Notes

Verify the specific manufacturer origin, as BSS138W appears in Infineon documentation but EVVO is listed as a distributor or solution provider in available records. Confirm that the datasheet parameters match the actual supplied component batch. Ensure the SOT-323 package dimensions align with your PCB footprint requirements before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a compact N-channel MOSFET with 60 V breakdown voltage is required. The SOT-323 package suits space-constrained designs. Consider the 6000 mΩ on-resistance at 4.5 V drive; ensure the application logic levels can sufficiently drive the gate to minimize conduction losses. Verify thermal management capabilities given the 0.5 W power dissipation limit.

Single FETs, MOSFETs Part Context

The BSS138W belongs to the broader BSS138 family of small signal MOSFETs. While standard BSS138 variants often use SOT-23 packages, the 'W' suffix typically denotes the SOT-323 (UMT3) form factor. This variant maintains similar electrical characteristics to its SOT-23 counterparts but offers a different physical footprint for integration into modern compact electronic assemblies.
