Integrated NPN Transistor
with Free Wheeling Diode to
Drive Inductive Loads
http://onsemi.com
This device is used to switch inductive loads between 1.0 V and
12 V such as small PCB relays, solenoids, and lamps. It is intended to
replace an array of these or more discrete components with an
integrated SMT device.
