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.
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 = 4,000 to 20,000 @VCE = −2.0 V, IC = −4.0 A
• On-chip C-to-E reverse diode
• Fast switching speed
