★
DESCRIPTION
ORDERING INFORMATION
The 2SA1841 is a high-speed Darlington power transistor.
PART NUMBER
PACKAGE
2SA1841
MP-10
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 automounted 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 = −2.0 V, IC = −4.0 A)
• On-chip C-to-E reverse diode
• Fast switching speed

Electronics product depend on its quality grade, as indicated below. Customers must check the quality grade of
each NEC Electronics product before using it in a particular application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots.
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support).
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC
Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in applications
not intended by NEC Electronics, they must contact an NEC Electronics sales representative in advance to
determine NEC Electronics' willingness to support a given application.
