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.
FEATURES
Auto-mounting possible in radial taping specifications
Resin-molded insulation type package with power rating of 1.8 W in stand-alone conditions
High DC current amplifiers due to Darlington connection
hFE = 4000 to 20000 (VCE =
