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

• On-chip C-to-E reverse diode

• Fast switching speed
