Transistor
2SD1478, 2SD1478A
Silicon NPN epitaxial planer type darlington
For low-frequency amplification
s Features
q Forward current transfer ratio hFE is designed high, which is ap-
propriate to the driver circuit of motors and printer bammer: hFE
= 4000 to 20000.
q A shunt resistor is omitted from the driver.
