MJE200G

MJE200G Description

The MJE200G from onsemi is a high-performance NPN bipolar junction transistor (BJT) designed for robust power amplification and switching applications. With a collector-emitter voltage (V_CE) rating of 40V and a collector current (I_C) capability of 5A, this transistor is engineered to handle moderate power loads efficiently. Its transition frequency of 65MHz ensures reliable performance in medium-speed switching circuits, while the low collector cutoff current (I_CBO) of 100nA minimizes leakage, enhancing energy efficiency. Packaged in a TO-126 through-hole form factor, the MJE200G is suitable for both prototyping and industrial applications, complying with ROHS3 and REACH environmental standards.
