BSP52T1/D
BSP52T1G, BSP52T3G
NPN Small-Signal
Darlington Transistor
This NPN small signal Darlington transistor is designed for use in
switching applications, such as print hammer, relay, solenoid and lamp
drivers. The device is housed in the SOT-223 package, which is
designed for medium power surface mount applications.
Features
• The SOT-223 Package can be soldered using wave or reflow. The
formed leads absorb thermal stress during soldering, eliminating the
possibility of damage to the die
• Available in 12 mm Tape and Reel
Use BSP52T1 to Order the 7 Inch/1000 Unit Reel
• PNP Complement is BSP62T1
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
