The KI2301DS is a MOSFET SOT23 RoHS (Restriction of Hazardous Substances) component, manufactured by KEXIN. The device is available in a small 3-pin SOT-23 package. It provides low on-state resistance and low gate charge for higher efficiency power switching. The KI2301DS has a gate threshold voltage of 4.5V and a drain to source voltage (VDS) rating of 30V. Its Drain to Source On-Resistance (RDS(on)) at 4.5V gate voltage is 0.4O, making it suitable for applications that require higher efficiency switching such as DC/DC converters, motor controls, and light dimming controls. The KI2301DS is RoHS compliant and is qualified for use in automotive applications.
