2SC4774T106S Description

Short technical summary and product information.

The 2SC4774T106S is an NPN bipolar junction transistor from ROHM Semiconductor, optimized for high frequency amplifier and RF switching applications. It offers a collector-emitter voltage (Vceo) of 6V, a collector current (Ic) of 50mA, and a typical transition frequency (fT) of 800MHz, making it suitable for RF circuits up to several hundred MHz.

 

Key electrical characteristics include a DC current gain (hFE) range of 270 to 560 at Vce=5V and Ic=5mA (rank S), low collector-emitter saturation voltage of 300mV max at Ic=10mA, and low output capacitance of 1.0pF typical. The transistor also features a very low on-resistance (Ron) of 2.0Ω typical, beneficial for switching applications.

 

The device is housed in a surface-mount UMT3 package (SOT-323/SC-70), with a power dissipation of 200mW. It is supplied in tape and reel packaging with 3000 pieces per reel, suitable for automated assembly. The operating junction temperature range is -55°C to +150°C.
