BC337 Description

Short technical summary and product information.

The BC337 is a general-purpose NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for switching and linear amplification applications requiring moderate voltage and current handling.

 

Key electrical specifications include a collector-emitter breakdown voltage (Vce) of 45V, a continuous collector current (Ic) of 800mA, and a maximum power dissipation of 625mW. The DC current gain (hFE) is a minimum of 100 at Ic=100mA and Vce=1V, with a saturation voltage (Vce(sat)) of 700mV maximum at Ib=50mA and Ic=500mA. The transition frequency (ft) is 210 MHz, making it suitable for low-frequency switching and amplification.

 

The transistor is housed in a TO-92-3 through-hole package (TO-226-3, TO-92-3 (TO-226AA)) and supports an operating junction temperature range of -55°C to 150°C. It is compliant with RoHS3 standards. The component is commonly used in general-purpose circuits such as signal drivers, preamplifiers, and low-power switching stages.
