FCX1149ATA Description

Short technical summary and product information.

The FCX1149ATA is a PNP silicon power switching transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage of -25V (minimum) and a continuous collector current rating of -3A, with a peak pulse current capability of -10A. The device offers a low saturation voltage of less than -80mV at -0.1A and a DC current gain (hFE) of 250 minimum at 500mA and 2V, making it suitable for switching applications requiring high efficiency.

 

The transistor has a transition frequency of 135 MHz typical and is designed for power switching circuits in various electronic systems. It can dissipate up to 2W of power (subject to board conditions) and operates over a junction temperature range of -55°C to 150°C.

 

Packaged in a SOT89-3 surface mount package (TO-243AA), the FCX1149ATA is supplied on tape and reel with 1,000 units per reel. The package is molded from UL 94V-0 rated green plastic and features matte tin plated leads, ensuring solderability per MIL-STD-202. The device is RoHS3 compliant and halogen- and antimony-free.
