2SC4081U3HZGT106R Description

Short technical summary and product information.

The 2SC4081U3HZGT106R from ROHM Semiconductor is an NPN bipolar junction transistor designed for general-purpose switching and amplification applications. It features a collector-emitter breakdown voltage (Vceo) of 50V and a continuous collector current (Ic) of 150mA, with a maximum power dissipation of 200mW.

Electrical characteristics include a minimum DC current gain (hFE) of 120 at Ic=1mA and Vce=6V, a maximum collector-emitter saturation voltage of 400mV at Ib=5mA and Ic=50mA, and a transition frequency (ft) of 180MHz. The device is rated for a maximum junction temperature of 150°C.

The transistor is offered in a compact surface-mount package with case options SC-70 and SOT-323, supplied as UMT3. It is designed for automated assembly and is suitable for space-constrained PCB layouts.

Environmental compliance based on existing database records indicates RoHS3 compliance, REACH unaffected, and MSL level 1 (unlimited).
