BSS138BKWT106

Overview

The BSS138BKWT106 is a single N-channel small-signal MOSFET manufactured by ROHM Semiconductor. It utilizes the UMT3 (SOT-323) surface-mount package and operates with a Drain-Source voltage of 60V and a continuous Drain current of 380mA. The device features a low on-resistance of 0.68Ω at Vgs=10V and supports a drive voltage as low as 2.5V. It includes built-in ESD protection rated at 2kV (HBM), ensuring robustness in sensitive circuits. The component is RoHS compliant, lead-free, and halogen-free, suitable for standard commercial applications excluding automotive use.

Feature Summary

Integrated ESD protection diode providing 2kV HBM protection
Ultra-low voltage drive capability at 2.5V
Fast switching performance optimized for signal processing
Lead-free plating with halogen-free material composition

Applications

Switching circuits
Low-side load switches
Relay drivers

Procurement Notes

Verify that the specific application does not require automotive-grade certification, as this standard-level product is explicitly not recommended for vehicle equipment. Confirm the UMT3/SOT-323 package dimensions match the PCB footprint requirements. Ensure the 60V rating and 380mA current capacity are sufficient for the target circuit's operational limits before finalizing procurement.

Selection Notes

Select this component for designs requiring compact SMD packaging with integrated ESD protection. It is suitable for low-voltage logic interfaces due to its 2.5V drive compatibility. Consider the thermal dissipation limits when designing for high-frequency switching environments. This part serves as a direct replacement for other BSS138 variants within the same series, provided the package type remains consistent.

Part Context

This device belongs to ROHM's small-signal MOSFET lineup, designed for general-purpose amplification and switching tasks. It complements other components like the BSS84W (P-channel) and BC848BW (NPN transistor) in the manufacturer's portfolio. The UMT3 package allows for high-density mounting on printed circuit boards, supporting modern miniaturization trends in consumer electronics and industrial control systems.
