DARLINGTON POWER TRANSISTOR
2SC4811
NPN SILICON EPITAXIAL TRANSISTOR (DARLINGTON CONNECTION)
FOR HIGH-SPEED SWITCHING
DATA SHEET
2002
The 2SC4811 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
• On-chip C-to-E reverse diode
• Fast switching speed
