FMMT459TA Description

Short technical summary and product information.

The FMMT459TA is a 500V NPN high voltage transistor from Diodes Incorporated, designed for off-line switching applications, RCD circuits, and PFC disable switches. It features a collector-emitter breakdown voltage of 450V (VCEO) and a collector-base breakdown voltage of 500V (VCBO). The continuous collector current is 150mA with a peak pulse current capability of 500mA. The transistor offers a DC current gain (hFE) of 50 minimum at 30mA and 10V, and a low saturation voltage of 90mV maximum at 50mA. The transition frequency is 50MHz. The device is housed in a SOT-23-3 surface-mount package with matte tin plated leads. It is fully RoHS compliant, halogen and antimony free, and qualified to AEC-Q101 standards for high reliability. The operating temperature range is -55°C to 150°C. Power dissipation is 625mW at 25°C ambient (Note 5) and 806mW (Note 6). The thermal resistance junction-to-ambient is 200°C/W (Note 5) and 155°C/W (Note 6). The device is supplied in tape and reel packaging with 3000 units per reel.
