Product Summary

The sts8dnf3ll is a specific Power MOSFET. The sts8dnf3ll is the second generation of STMicroelectronis unique Single Feature Size strip-based process. The resulting transistor shows the best trade-off between on-resistance and gate charge. When used as high and low side in buck regulators, it gives the best performance in terms of both conduction and switching losses. This is extremely important for motherboards where fast switching and high efficiency are of paramount importance. It is specifically designed and optimised for high efficiency cpu core dc/dc converters for mobile PCS.

Parametrics

sts8dnf3ll absolute maximum ratings: (1)VDS Drain-source Voltage (VGS = 0): 30 V; (2)VDGR Drain-gate Voltage (RGS = 20 kW): 30 V; (3)VGS Gate- source Voltage: ± 16 V; (4)ID Drain Current (continuous)at TC = 25°C Single Operation: 8 A; (5)Drain Current (continuous)at TC = 100°C Single Operation: 5A; (6)IDM(·)Drain Current (pulsed): 32 A; (7)Ptot Total Dissipation at TC = 25°C Dual operating: 2W.

Features

sts8dnf3ll features: (1)typical rds(on)= 0.017Ω; (2)optimal rds(on)x qg trade-off @ 4.5v; (3)conductiolosses reduced; (4)switching losses reduced.
