RN1961FE~RN1966FE TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process) (Bias Resistor built-in Transistor) RN1961FE,RN1962FE,RN1963FE RN1964FE,RN1965FE,RN1966FE 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 RN2961FE~RN2966FE Equivalent Circuit and Bias Resistor Values C Type No. R1 (k?)
