Product Summary

The STD40NF03LT4 Power MOSFET is the third generation of STMicroelectronics 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. The STD40NF03LT4 is used in Switching application.

Parametrics

STD40NF03LT4 absolute maximum ratings: (1)Drain-source voltage (VGS = 0): 30 V; (2)VDGR Drain-gate voltage (RGS = 20 kΩ): 30 V; (3)VGS Gate- source voltage: ±20 V; (4)Drain current (continuous)at TC = 25°C: 40 A; (5)ID Drain current (continuous)at TC = 100°C: 28 A; (6)Drain current (pulsed): 160 A; (7)Ptot Total dissipation at TC = 25°C: 80 W.

Features

STD40NF03LT4 features: (1)Logic level device; (2)Optimal RDS(on)x Qg trade-off; (3)Conduction losses reduced; (4)Switching losses reduced; (5)Low threshold drive.
