Description

Product Overview

The STD25NF20 is an AEC-Q101 qualified automotive N-channel power MOSFET from STMicroelectronics, manufactured using the STripFET single-feature-size strip process. In a DPAK (TO-252) package, it delivers 200 V drain-source breakdown voltage, 18 A continuous drain current, and a typical RDS(on) of 0.10 Ω at VGS = 10 V. Every device is 100% avalanche tested, guaranteeing 110 mJ single-pulse avalanche energy capability.

Features

  • STripFET single-feature-size strip process for high cell density and low RDS(on)
  • 100% avalanche tested for inductive load ruggedness
  • Low gate charge (28 nC typ) reduces driving losses
  • Excellent dv/dt capability (15 V/ns) for freewheeling applications
  • Low thermal resistance: Rth(j-c) = 1.38 °C/W

Applications

  • Automotive 48 V motor drive
  • Automotive load switches and relay replacement
  • DC-DC converters
  • Automotive lighting drivers
  • Industrial switching applications

The STD25NF20 is an AEC-Q101 qualified automotive N-channel power MOSFET from STMicroelectronics using STripFET technology. It delivers 200V drain-source voltage, 18A continuous current, and 0.10 ohm typical RDS(on) in a DPAK package. The strip layout process achieves high cell density with low gate charge (28nC typ) and robust avalanche capability (110mJ EAS, 100% tested). dv/dt rating of 15V/ns suits inductive load applications.

STripFET technology uses a single-feature-size strip cell layout that reduces critical alignment steps, improving manufacturing consistency and enabling high cell density for low RDS(on). The strip structure also enhances avalanche ruggedness and gate charge performance. 100% avalanche testing ensures every device withstands inductive turn-off energy. The DPAK tab connects directly to the drain, providing a low thermal resistance path to the PCB copper for efficient heat dissipation.
