2N4923 Description

Short technical summary and product information.

The 2N4923G is a medium-power NPN silicon transistor from onsemi designed for driver circuits, switching, and amplifier applications. It features a collector-emitter voltage (VCEO) of 80V and a continuous collector current rating of 1A, with a peak current capability of 3A. The device offers a maximum power dissipation of 30W at a case temperature of 25°C, derated linearly above 25°C at 0.24 W/°C.

 

Electrical characteristics include a DC current gain (hFE) of minimum 30 at Ic=500mA and Vce=1V, and a low Vce saturation voltage of 600mV maximum at Ib=100mA and Ic=1A. The transition frequency is nominally 3MHz. The transistor is housed in a TO-225AA (TO-126-3) through-hole package and is Pb-Free and RoHS compliant per the datasheet.

 

This device is complementary to the PNP 2N4920G and is suitable for general-purpose power switching and linear amplification in industrial and consumer electronics.
