MJH6284G

MJH6284G Description

The MJH6284G from onsemi is a high-performance NPN Darlington bipolar junction transistor (BJT) designed for demanding power-switching and amplification applications. With a collector-emitter breakdown voltage (V_CE) of 100V and a maximum collector current (I_C) of 20A, this transistor is engineered for high-power efficiency and reliability. Its low V_CE saturation voltage (3V @ 200mA, 20A) ensures minimal power loss, while the high DC current gain (h_FE ≥ 750 @ 10A, 3V) enhances signal amplification. Packaged in a TO-247-3 through-hole format, the MJH6284G is optimized for robust thermal dissipation, supporting a maximum power dissipation of 160W.
