Product data sheet
1. Product profile
1.1 General description
Logic level N-channel enhancement mode Field-Effect Transistor (FET) in a plastic
package using
Nexperia
High Performance Automotive (HPA) TrenchMOS
technology. This product has been designed and qualified to the appropriate AEC
standard for use in automotive critical applications.
1.2 Features and benefits
Low conduction losses due to low
on-state resistance
Suitable for logic level gate drive
sources
Q101 compliant
Suitable for thermally demanding
environments due to 175
°C
rating
1.3 Applications
Air bag
Automotive transmission control
Fuel pump and injection
Automotive ABS systems
Diesel injection systems
Motors, lamps and solenoids
