BSS138TA-79

Overview

The BSS138TA-79 is a single N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a maximum drain-source breakdown voltage of 50 V and a continuous drain current of 200 mA. The device exhibits a maximum on-resistance of 3.5 Ohms at a gate-source voltage of 5 V. It operates within a temperature range of -55°C to +150°C with a power dissipation rating of 350 mW. Packaged in an SOT-23-3 surface-mount case, it utilizes silicon technology for reliable performance in low-power switching applications.

Feature Summary

Single N-channel configuration for discrete switching control
Enhancement mode operation with low threshold voltage
Surface-mount construction in a compact three-terminal package

Applications

Low-side switching in portable electronic devices
Level shifting between different logic voltage domains
General-purpose signal switching in consumer electronics

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure that the component meets all required environmental compliance standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a single N-channel switch is required with moderate voltage handling capabilities. Consider the thermal constraints imposed by the 350 mW power dissipation limit and ensure the application current remains below the 200 mA continuous drain current rating for safe operation.

Part Context

This part belongs to the BSS138 series of small-signal MOSFETs from Diodes Incorporated. The series is widely utilized in general-purpose switching applications where space efficiency and low cost are primary design drivers. The TA variant specifically denotes the tape and reel packaging format suitable for automated assembly processes.
