Darlington Transistor
BSP52T1
Motorola Preferred Device
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.

SURFACE MOUNT
• 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
Use BSP52T3 to order the 13 inch/4000 unit reel
• PNP Complement is BSP62T1
