DARLINGTON POWER TRANSISTOR
2SA1841
PNP SILICON EPITAXIAL TRANSISTOR (DARLINGTON CONNECTION)
FOR HIGH-SPEED SWITCHING
The 2SA1841 is a high-speed Darlington power transistor. This transistor is ideal for high-precision control such
as PWM control for pulse motors or 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.
