BSS138NT1G in TXS0108 / BSS138 Level Shifters Family
The BSS138NT1G is a high-performance N-channel logic-level MOSFET optimized for low-voltage switching and level translation applications. Manufactured primarily by ON Semiconductor (onsemi) and Diodes Inc, this sub-family provides a reliable solution for interfacing between disparate logic domains, such as 1.8V, 3.3V, and 5V systems. Its low gate threshold voltage and high-speed switching characteristics make it a ubiquitous choice for bidirectional level shifting in digital communication buses.
The variants within the BSS138NT1G sub-family primarily differ in their packaging options, tape-and-reel quantities, and minor variations in maximum continuous drain current (Id) across different manufacturers. While the core electrical characteristics remain consistent for interchangeable use, some specific part numbers may include AEC-Q101 qualification for automotive applications or enhanced ESD protection diodes integrated into the gate structure to prevent latch-up in harsh environments.
