Transistor
2SD1205, 2SD1205A
Silicon NPN epitaxial planer 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 bammer: h
= 4000 to 2000.
●
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.
