This product complies with the RoHS Directive (EU 2002/95/EC).
2SD0946
Silicon NPN epitaxial planar type darlington
For low-frequency amplication
Features
Forward current transfer ratio hFE is designed high, which is appropriate to
the driver circuit of motors and printer hammer.
A shunt resistor is omitted from the driver.
