RN1901FE~RN1906FE TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process) (Bias Resistor built-in Transistor) RN1901FE,RN1902FE,RN1903FE RN1904FE,RN1905FE,RN1906FE Switching, Inverter Circuit, Interface Circuit and Unit: mm Driver Circuit Applications • Two devices are incorporated into an Extreme-Super-Mini (6 pin) package. • Incorporating a bias resistor into a transistor reduces parts count. Reducing the parts count enable the manufacture of ever more compact equipment and save assembly cost. • Complementary to RN2901FE~RN2906FE Equivalent Circuit and Bias Resistor Values C Type No. R1 (k?)
