BFQ251 is a PNP video transistor with high breakdown voltages, low output capacitance, high gain bandwidth, and good thermal stability. It is suitable for buffer/driver applications in high-resolution color graphics monitors.
The document is a product specification datasheet for the Philips BFQ251, a PNP video transistor designed for use in high-resolution colour graphics monitors. It features high breakdown voltages, low output capacitance, and high gain bandwidth. The transistor is available in a SOT54 plastic package or TO-92 package.
The maximum total power dissipation is 1 W when the temperature at the soldering point of the collector pin is less than 65 °C.
The maximum DC collector current is 300 mA.
The transistor requires a metallized pad area of 10 mm² when mounted on a printed-circuit board.
