RN2975 TOSHIBA Transistor Silicon PNP Epitaxial Type (PCT process) (Bias Resistor Built-in Transistor) RN2975 Switching, Inverter Circuit, Interface Circuit and Unit: mm Driver Circuit Applications. • Two devices are incorporated into an Ultra-Super-Mini (6-pin) package • Incorporating a bias resistor into a transistor reduces the parts count. Reducing the parts count enables the manufacture of ever more compact equipment and lowers assembly cost. Equivalent Circuit and Bias Resistor Values C R1 B E R1: 2.2 k? (Q1, Q2 common) JEDEC ?
