The BC549 is an NPN bipolar junction transistor manufactured by ON Semiconductor. It is housed in a through-hole TO-92-3 package (TO-226-3, TO-226AA) with a supplier device package of TO-92-3. This transistor is designed for general purpose amplification and switching applications in low-power circuits.
Key electrical specifications include a maximum collector-emitter voltage of 30V, a maximum collector current of 100mA, and a power dissipation of 500mW. The DC current gain (hFE) is at least 110 at 2mA collector current and 5V collector-emitter voltage. The saturation voltage (Vce) is 600mV maximum at 5mA base current and 100mA collector current. The transition frequency is 300MHz, making it suitable for low-frequency signal processing.
The operating junction temperature is rated up to 150°C. The transistor is through-hole mounted, fitting standard TO-92 footprints. Compliance data indicates RoHS3, REACH unaffected, and MSL level 1 (unlimited), though these are unverified.
The maximum collector-emitter voltage (Vce) is 30V.
The BC549 is available in a TO-226-3, TO-92-3 (TO-226AA) package, with a supplier device package of TO-92-3.
The operating junction temperature is rated up to 150°C (TJ).
The BC549 is listed as RoHS3 compliant, though this status is unverified and has low confidence.
The maximum collector current is 100 mA.
The minimum DC current gain (hFE) is 110 at Ic=2mA and Vce=5V.
The transition frequency is 300 MHz.
