The BUL38D is an NPN bipolar junction transistor manufactured by STMicroelectronics. It is designed for general-purpose switching and linear amplification applications requiring high voltage and moderate current handling.
Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 450V, a continuous collector current (IC) rating of 5A, and a power dissipation (Pd) of 80W. The DC current gain (hFE) is a minimum of 10 at Ic=10mA and Vce=5V, and the collector-emitter saturation voltage (Vce(sat)) is a maximum of 1.1V at Ib=750mA and Ic=3A.
The transistor is housed in a TO-220-3 through-hole package, which provides good thermal performance. The maximum operating junction temperature (Tj) is 150°C. The device is RoHS3 compliant and has an MSL of Level 1 (unlimited).
Typical applications include power supply circuits, motor control drivers, and high-voltage inverters where the combination of 450V breakdown and 5A current capability is required.
