MJD200G

MJD200G Description

The MJD200G from onsemi is a high-performance NPN bipolar junction transistor (BJT) designed for robust switching and amplification applications. Packaged in a DPAK (TO-252) surface-mount form factor, it offers a collector-emitter voltage (V_CE) rating of 25V and a maximum collector current (I_C) of 5A, making it suitable for medium-power circuits. With a transition frequency (f_T) of 65MHz, it balances speed and efficiency, while its low V_CE(sat) of 1.8V at 5A ensures minimal power loss in saturated switching conditions. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
