DESCRIPTION
The 2SA1841 is a high-speed Darlington power transistor.
This transistor is ideal for high-precision control such as PWM
control for pulse motors brushless motors in OA and FA equipment.
In addition, this transistor features a package that can be auto-
mounted in radial taping specifications, thus contributing to
mounting cost reduction.
