Details

The BSS138 is a high-performance N-channel enhancement-mode field-effect transistor (MOSFET) manufactured using advanced DMOS technology. It is specifically designed for low-voltage and low-current applications, making it a popular choice for logic level shifting in mixed-voltage digital systems. With a low gate threshold voltage of just 1.5V and a low on-resistance of 3.5Ω, it is perfectly suited for interfacing 3.3V microcontrollers with 5V sensors or peripherals. This component is commonly used in I2C, SPI, and TTL serial communication interfaces to prevent damage to sensitive low-voltage components. Its compact SOT-23 package makes it ideal for space-constrained PCB designs. Choose the BSS138 for reliable, efficient switching and level translation in your next electronics project.
