2N7002NXBKR N-Channel MOSFET General Purpose Switch (60V, 2.8Ω, SOT-23)

Seamlessly bridge the gap between different logic voltage levels in your circuits with the 2N7002NXBKR N-Channel MOSFET. When you need to connect a 5V sensor to a 3.3V microcontroller (like an ESP32 or STM32), sending 5V directly into a 3.3V pin can permanently damage the chip. This tiny, highly efficient transistor is the industry-standard solution for building bi-directional logic level shifters (perfect for I2C and SPI buses), ensuring safe and reliable communication between mismatched components.

Unlike bipolar transistors (BJTs) that require continuous current to stay switched on, this MOSFET is voltage-controlled. This means it draws virtually zero current from your microcontroller's GPIO pin, leaving more power for the rest of your circuit. With a massive 60V drain-source voltage rating and a typical on-resistance of 2.8 Ohms, it is also highly capable of switching small external loads like status LEDs, micro-relays, and buzzer circuits in custom drone PDBs or smart home IoT projects. Housed in a microscopic SOT-23 package, it is an absolute must-have in every maker's component bin.

Key Features:

• Voltage-Controlled Switching: Draws almost zero gate current from your microcontroller, reducing thermal load and power consumption on sensitive CPU pins.

• Ultimate Level Shifter: The go-to component for designing safe, bi-directional 3.3V to 5V logic level translation circuits for I2C, SPI, and UART lines.

• High Voltage Tolerance: The impressive 60V breakdown voltage makes it safe to use for signaling in 12V, 24V, and even 48V (up to 14S LiPo) industrial systems.

• Space-Saving SOT-23: The tiny surface-mount footprint is perfect for densely populated custom PCBs and micro-robotics.
