FCX1053ATA Description

Short technical summary and product information.

The FCX1053ATA is a 75V NPN medium power transistor from Diodes Incorporated, designed for high-current switching and amplification applications. It features a collector-emitter breakdown voltage (BVCEO) greater than 75V, a continuous collector current (IC) of 3A, and a peak pulse current (ICM) of 10A. The device offers a high DC current gain (hFE) of at least 300 at 500mA, and a low saturation voltage (VCE(sat)) of 440mV at 4.5A, with an equivalent on-resistance of 78mΩ at 4.5A.

 

The transistor has a transition frequency (ft) of 140MHz, making it suitable for moderate-speed switching. It can dissipate up to 2W at 25°C ambient temperature, with a junction-to-ambient thermal resistance of 125°C/W. The operating junction temperature range is -55°C to 150°C.

 

Packaged in the SOT89-3 (TO-243AA) surface-mount case, the FCX1053ATA is qualified to AEC-Q101 standards for automotive and high-reliability applications. It is RoHS3 compliant, lead-free, halogen-free, and antimony-free, with a moisture sensitivity level of 1.

 

Typical applications include emergency lighting circuits, motor driving (including DC fans), solenoid and relay drivers, DC-DC modules, backlight inverters, power switches, and MOSFET gate drivers.
