MJF127G

MJF127G Description

The MJF127G from onsemi is a high-performance PNP Darlington transistor designed for demanding power applications. With a collector-emitter voltage (Vce) rating of 100V and a maximum collector current (Ic) of 5A, this device is engineered to deliver robust performance in high-voltage, high-current circuits. Its low collector cutoff current (10µA max) and high DC current gain (hFE ≥ 2000 @ 3A, 3V) ensure efficient switching and amplification, making it ideal for applications requiring minimal leakage and high gain. Packaged in a TO-220FP (fully insulated) through-hole mount, the MJF127G offers excellent thermal dissipation and electrical isolation, complying with ROHS3 and REACH environmental standards.
