2N3904TFR Description

Short technical summary and product information.

2N3904TFR is an NPN bipolar junction transistor manufactured by ON Semiconductor. It is designed for general purpose switching and amplification applications.

 

Key electrical specifications include a maximum collector-emitter voltage of 40V, maximum collector current of 200mA, and a typical transition frequency of 300MHz. The DC current gain (hFE) is minimum 100 at 10mA collector current and 1V collector-emitter voltage. The maximum Vce saturation voltage is 300mV at 5mA base current and 50mA collector current.

 

The transistor can dissipate up to 625mW of power and operates over a junction temperature range of -55°C to 150°C. It is housed in a TO-92-3 through-hole package, also known as TO-226-3, with formed leads.

 

This component is suitable for low-power switching circuits, signal amplification, and driver stages in consumer and industrial electronics.
