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

formed leads absorb thermal stress during soldering, eliminating the

possibility of damage to the die
