The BD439 is an NPN bipolar junction transistor manufactured by On Semiconductor. It features a maximum collector-emitter voltage of 60V, a maximum collector current of 4A, and a power dissipation of 36W. The DC current gain (hFE) is a minimum of 40 at a test condition of Ic=500mA, Vce=1V. The collector-emitter saturation voltage is a maximum of 800mV at Ib=300mA, Ic=3A. The transition frequency is 3 MHz.
The transistor is housed in a through-hole TO-225AA/TO-126-3 package, with the supplier device package designated as TO-126. It operates over a junction temperature range of -55°C to 150°C. The BD439 is listed as RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited). This device is suitable for general-purpose switching and amplification applications.
