The STMicroelectronics ST8812FX is a high-voltage, fast-switching NPN Power Transistor designed for demanding applications. Manufactured using Multi Epitaxial Planar technology, it offers high voltage capability and a wide Reverse Biased Safe Operating Area (R.B.S.O.A.).
Key electrical specifications include a collector-emitter voltage of 600V and a continuous collector current of 7A, with a peak current capability of 12A. The transistor features a maximum total power dissipation of 50W at 25°C case temperature and a junction-to-case thermal resistance of 2.5°C/W.
This device is suitable for switch mode power supplies, particularly for CRT TVs. It comes in a fully insulated ISOWATT-218FX package, which is U.L. compliant for easy mounting. The operating junction temperature can reach up to 150°C.
Additional electrical characteristics include a collector-emitter saturation voltage of 3V at 4A/0.8A and a DC current gain (hFE) of 4.5 at 5A/5V. Switching characteristics include a storage time of 1µs and a fall time of 60ns under inductive load conditions.
