Part number : 2SA1073, 2SA1072
Function : SILICON HIGH SPEED POWER TRANSISTOR
Manufacturer : Fujitsu Media Devices Limited
The 2SA1073 are silicon PNP general purpose, high power switching transistors fabricated with Fujitsu’s unique Ring Emitter Transistor ( RET ) technology. RET devices are constructed with multiple emitters connected through diffused ballast resistors which provide uniform current density. This structure permits the design of high power transistors with exceptional switching characteristics and frequency reponse in high current applications.
