RN4904 Description

Short technical summary and product information.

The Toshiba RN4904 is a versatile silicon transistor designed for switching, inverter, interface, and driver circuit applications. It integrates both PNP and NPN transistors within a single US6 (ultra super mini type with 6 leads) package, simplifying circuit design and reducing component count.

Key electrical characteristics include a collector-emitter voltage (VCEO) of up to 50V and a collector current (IC) of 100mA. The device features built-in bias resistors (R1 and R2, both 47kΩ) which further streamline implementation. The RN4904 operates with a junction temperature up to 150°C and a storage temperature range of -55°C to 150°C.

This transistor is suitable for various electronic designs requiring compact and reliable switching or amplification. Its pre-biased nature simplifies external circuitry, making it an efficient choice for engineers looking to optimize board space and manufacturing processes.
