BF904R

Enhancement type field-effect transistor BF904R in a plastic microminiature SOT143B and SOT143R package. The transistor consists of an amplifier MOS-FET with source

The BF904R is one member of the N-channel dual gate MOS-FETs family,it is produced by the Philips Semiconductors with some features such as:(1)specially designed for use at 5 V supply voltage;(2)short channel transistor with high transfer admittance to input capacitance ratio;(3)low noise gain controlled amplifier up to 1 GHz;(4)superior cross-modulation performance during AGC.It can be used in the VHF and UHF applications with 3 to 7 V supply voltage such as television tuners and professional communications equipment.But something should be caution:this product is supplied in anti-static packing to prevent damage caused by electrostatic discharge during transport and handling.For further information,refer to Philips specs.:SNW-EQ-608,SNW-FQ-302A and SNW-FQ-302B.

The absolute maximum ratings of the BF904R can be summarized as:(1)drain-source voltage:7 V;(2)drain current:30 mA;(3)total power dissipation:200 mW;(4)operating junction temperature:150 °C;(5)forward transfer admittance:22 to 30 mS;(6)input capacitance at gate 1:2.2 pF;(7)reverse transfer capacitance(f=1 MHz):25 pF;(8)noise figure(f=800 MHz):2 dB;(9)storage temperature:-65 to +150 °C;(10)operating junction temperature:150 °C.
