BUK7909-75ATE
N-channel TrenchPLUS standard level FET
Rev. 02 — 16 February 2009
Product data sheet
1. Product profile
1.1 General description
Standard level N-channel enhancement mode Field-Effect Transistor (FET) in a plastic
package using TrenchMOS technology. The devices include TrenchPLUS diodes for
ElectroStatic Discharge (ESD) protection and temperature sensing. This product has been
designed and qualified to the appropriate AEC standard for use in automotive critical
applications.
1.2 Features and benefits
Allows responsive temperature
monitoring due to integrated
temperature sensor
Electrostatically robust due to
integrated protection diodes
Low conduction losses due to low
on-state resistance
Q101 compliant
Suitable for standard level gate drive
sources
1.3 Applications
Electrical Power Assisted Steering
(EPAS)
Variable Valve Timing for engines
