Description
SOT 23 SMD Mosfet Transistor P-Channel N-Channel
The SI2302 is a commonly used N-Channel Enhancement Mode MOSFET designed for low voltage switching applications. It comes in a compact SOT-23 surface-mount (SMD) package, making it suitable for compact PCBs and high-density circuits. It is known for its low gate threshold voltage, low on-resistance (R<sub>DS(on)</sub>), and high-speed switching performance.
