The FMMT459TA is a high-voltage NPN transistor designed for various applications including off-line switching, RCD circuits, and emergency lighting. It features a collector-emitter breakdown voltage (VCEO) of 450V and a collector-base voltage (VCBO) of 500V, making it suitable for high-voltage environments. The device can handle a continuous collector current (IC) of 150mA and a peak pulse current (ICM) of up to 500mA, with a maximum power dissipation of 625mW. This transistor exhibits low saturation voltage characteristics, with a typical value of less than 90mV at 50mA, and provides excellent current gain (hFE) performance up to 120mA. The FMMT459TA is packaged in a compact SOT-23 case, is fully RoHS compliant, and is classified as a "Green" device, indicating it is free from halogens and antimony. It is also qualified to AEC-Q101 standards, ensuring high reliability for automotive applications. The operating temperature range is from -55¬8C to +150¬8C, making it versatile for various environmental conditions.
