SI4403CDY-T1-GE3 VISHAY Power MOSFET

The SI4403CDY-T1-GE3 from Vishay Siliconix is a 20V P-Channel TrenchFET® power MOSFET in a compact SO-8 surface-mount package, delivering a low 15.5mΩ RDS(on) at 4.5Vgs for efficient load switching and power management. Its 1V max Vgs(th) threshold enables direct 1.8V logic-level drive from microcontrollers or PMICs, making it ideal for battery-operated devices where minimal voltage overhead is critical. With 13.4A continuous drain current and 90nC gate charge, it excels in DC-DC converters, USB power distribution, battery charging circuits, and reverse polarity protection. TrenchFET® technology reduces conduction losses and improves thermal performance in ultrabooks, tablets, smartphones, and IoT endpoints. The device is 100% Rg and UIS tested, RoHS-compliant, halogen-free per IEC 61249-2-21, and supplied in tape & reel for automated assembly. Operating from -55°C to +150°C, it provides a reliable solution for space-constrained designs requiring low-voltage, high-efficiency P-Channel switching.
