BF259 is a silicon planar epitaxial NPN transistor from STMicroelectronics, housed in a Jedec TO-39 metal case. It is specifically designed for video output stages in CTV and MTV sets, class A audio output stages, and drivers for horizontal deflection circuits.
The device offers a collector-emitter voltage (VCEO) of 300V and a collector current rating of 100mA DC (200mA peak). It provides a DC current gain (hFE) of 25 minimum at 30mA collector current and 10V VCE, with a transition frequency of 90MHz typical. The collector-emitter saturation voltage is 1V maximum at 30mA and 6mA base current.
The transistor comes in a through-hole mounting TO-205AD/TO-39-3 metal can package with a supplier device package of TO-39. It has a maximum power dissipation of 5W at an ambient temperature up to 50°C, and an operating junction temperature of 200°C.
