Product introduction：
1. K2158A-T1B-AT-VB Product Introduction
K2158A-T1B-AT-VB is a small single N-channel MOSFET in SOT23-3 package, designed for low voltage and low and medium power applications. The maximum drain-source voltage (VDS) of this MOSFET is 60V, suitable for operation in a lower voltage environment, with a maximum drain current (ID) of 0.3A. Its threshold voltage is 1.7V and the gate-source voltage range is ±20V, suitable for various drive circuits. K2158A uses Trench technology to achieve lower on-resistance: 3100mΩ at VGS of 4.5V, and reduced to 2800mΩ at VGS of 10V, thereby improving overall efficiency and reducing power consumption.
