RN1701JE~RN1706JE TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT Process) (Bias Resistor Built-in Transistor) RN1701JE,RN1702JE,RN1703JE RN1704JE,RN1705JE,RN1706JE Switching, Inverter Circuit, Interface Circuit and Unit: mm Driver Circuit Applications • Two devices are incorporated into an Extreme-Super-Mini (5 pin) package. • Incorporating a bias resistor into a transistor reduces parts count. Reducing the parts count enables the manufacture of ever more compact equipment and lowers assembly cost. • A wide range of resistor values is available for use in various circuit designs. • Complementary to RN2701JE~RN2706JE Equivalent Circuit and Bias Resistor Values 1.BASE1 (B1) 2.EMITTER (E) 3.BASE2 (B2) C 4.COLLECTOR2 (C2) Type No. R1 (k?)
