RN1609(TE85L,F)

Overview

The RN1609(TE85L,F) is a dual NPN Bias Resistor Built-in Transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates two NPN transistors with internal bias resistors into a single surface-mount package, specifically the SM6 (SOT-457) configuration. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Internal resistance values are typically 22kΩ for R1 and 47kΩ for R2. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 10mA/5V, a saturation voltage of 300mV max at 250µA base current, and a transition frequency of 250MHz. Power dissipation is rated at 300mW.
