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
h
FE = 4000 to 20000 (VCE = −2.0 V, IC = −4.0 A)
• On-chip C-to-E reverse diode
• Fast switching speed
