2N4401TA Description

Short technical summary and product information.

The 2N4401TA is a general-purpose NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for low-power switching and amplification applications.

 

Key electrical specifications include a maximum collector-emitter voltage of 40V, a maximum collector current of 600mA, and a maximum power dissipation of 625mW. The device offers a minimum DC current gain (hFE) of 100 at 150mA collector current and 1V collector-emitter voltage. The transition frequency is 250 MHz, making it suitable for moderate-speed switching circuits.

 

The transistor is housed in a TO-226-3 (TO-92-3) through-hole package with formed leads, enabling easy insertion into printed circuit boards or breadboards. The operating junction temperature range is -55°C to 150°C.
