2SC4081UBTLR Description

Short technical summary and product information.

The 2SC4081UBTLR is an NPN bipolar junction transistor manufactured by ROHM Semiconductor. It is designed for general-purpose switching and amplification applications. Key electrical specifications include a collector-emitter voltage (Vceo) of 50V, a collector current (Ic) of 150mA, and a power dissipation of 200mW. The transistor offers a DC current gain (hFE) of 120 minimum at 1mA collector current and 6V Vce, and a transition frequency (ft) of 180MHz. The maximum Vce saturation voltage is 400mV at 5mA base current and 50mA collector current. The device is housed in a surface-mount SC-85 package with a UMT3F supplier device package. It is RoHS3 compliant and has an MSL of 1 (unlimited). The operating junction temperature is up to 150°C. This transistor is suitable for compact, low-power designs where space is limited.
