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 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
AEC Q101 compliant
Low conduction losses due to low
on-state resistance
Suitable for logic level gate drive
sources
Suitable for thermally demanding
environments due to 175 °C rating
1.3 Applications
12 V and 24 V loads
Automotive and general purpose
power switching
Motors, lamps and solenoids
