Silicon NPN epitaxial planar type darlington
For low-frequency amplification
■ Features
• Forward current transfer ratio hFE is designed high, which is appropriate to the driver circuit of motors and printer hammer: hFE = 4000 to 20 000.
• A shunt resistor is omitted from the driver.
• M type package allowing easy automatic and manual insertion as well as stand-alone fixing to the printed circuit board.
