Back to previous pageProduct introduction：
1. K2103-VB Product Introduction
K2103-VB is a high-efficiency single N-channel MOSFET packaged in a small SOT89, designed for low-voltage, high-current applications. The maximum drain-source voltage (VDS) of this MOSFET is 30V, which is suitable for use in low-voltage environments. It has a maximum drain current (ID) of 6.8A, which can meet the needs of various medium-power applications. Its threshold voltage is 1.7V and the gate-source voltage range is ±20V, which is suitable for a variety of drive circuits. K2103-VB uses Trench technology to achieve extremely low on-resistance: 30mΩ at VGS of 2.5V, and reduced to 22mΩ at VGS of 4.5V, greatly improving efficiency and reducing heat generation.
