RN2909,LF(CT

Overview

The RN2909,LF(CT is a dual PNP digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two pre-biased transistors within a compact US6 (SOT-363) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of -50V and a continuous collector current of -100mA per element. The device features built-in bias resistors with typical values of 47kΩ for R1 and 22kΩ for R2. It operates with a minimum DC current gain (hFE) of 70 at specified test conditions and supports a transition frequency up to 250MHz. The component is rated for a maximum power dissipation of 200mW and complies with AEC-Q101 automotive standards.
