Product introduction：
K2158A-T1B-A-VB MOSFET Product Introduction:
K2158A-T1B-A-VB is a high-performance **single N-channel** MOSFET, which adopts **SOT23-3** package, with ultra-small size and excellent heat dissipation performance. The **drain-source voltage (VDS)** of this MOSFET can reach 60V, which is suitable for a variety of low-voltage power applications. Its gate-source voltage (VGS) is rated at ±20V, ensuring reliability under voltage fluctuations. The threshold voltage (Vth) is 1.7V, which enables it to turn on quickly at a lower gate voltage. At VGS=4.5V, the **on-resistance (RDS(ON))** is 3100mΩ, and at VGS=10V it is 2800mΩ, which can provide stable current output and the maximum leakage current can reach 0.3A. The use of **Trench** technology enables K2158A-T1B-A-VB to excel in high switching frequency and low energy consumption, making it particularly suitable for use in a variety of mobile devices and low-power power management applications.
