BSS138AKDWS-TP

Overview

The BSS138AKDWS-TP is a dual N-channel enhancement mode MOSFET manufactured by Micro Commercial Components. It utilizes silicon technology and is housed in an SOT-363S surface-mount package. The device features a drain-source breakdown voltage of 50 V and supports a continuous drain current of 220 mA. Key electrical characteristics include a maximum on-resistance of 3 Ohms at 10 V gate drive, a threshold voltage of 1.45 V at 250 µA, and a power dissipation rating of 350 mW. It operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• Dual configuration integrating two independent N-channel MOSFETs into a single compact package for space-constrained designs.
• Enhancement mode operation optimized for efficient switching performance with low input capacitance.
• Robust thermal management capabilities supporting high junction temperatures up to 150°C.

Applications

• Level shifting circuits requiring dual channel isolation
• Load switching applications for low-power digital loads
• General-purpose switching in portable electronic devices

Procurement Notes

Verify the specific suffix 'KDWS' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging specifications and marking codes. Ensure that the ordering information matches the required quantity per reel as defined in the latest production documentation. Cross-reference the RoHS compliance status directly with the component label or official certification documents prior to procurement.

Selection Notes

Select this component when a dual N-channel topology is required in a minimal footprint SOT-363S package. It serves as a suitable alternative to single-channel MOSFETs where board space is limited but two switching paths are necessary. Consider its 50V rating and 220mA current capacity for low-voltage logic level applications. Verify that the 3 Ohm on-resistance meets the efficiency requirements of the target load circuit.

Part Context

This part belongs to the BSS138 series of small-signal MOSFETs from Micro Commercial Components. It shares the core electrical architecture of the standard BSS138 but is packaged in the SOT-363S format to provide dual channels. This series is widely used in consumer electronics and industrial control systems where reliable low-power switching is essential.
