The JMTL3401A with MOSFET P Trench 30V 4.2A (Tc) 1.3V @ 250uA 55mO @ 4.2A, 10V SOT-23 RoHS is a power transistor manufactured by JieJie. It is designed for high-performance power applications, featuring low on-state resistance and high per unit temperature efficiency, as well as improved high-side switch performance. This MOSFET transistor uses the latest trench MOSFET technology, which provides excellent performance and reliability. Due to its low on-state resistance, the JMTL3401A can handle large power loads with minimum losses. Additionally, its high-side switch performance helps to reduce the switching losses significantly. The SOT-23 package ensures small size and high power density, while the RoHS-compliant design makes it suitable for use in hazardous environments.
