AT-41511

AT-41511, AT-41533 General Purpose, Low Noise NPN Silicon Bipolar Transistors Data Sheet Description Avago’s AT-41511 and AT-41533 are general purpose NPN bipolar transistors that offer excellent high frequency performance at an economical price. The AT-41533 uses the 3 lead SOT-23, while the AT-41511 places the same die in the lower parasitic 4 lead SOT-143. Both packages are industry standard, and compatible with high volume surface mount assembly techniques. The 4 micron emitter-to-emitter pitch of these transistors yields high performance products that can perform a multiplicity of tasks. The 14 emitter finger interdigitated geometry yields an intermediate-sized transistor with easy to match to impedances, low noise figure, and moderate power. Optimized for best performace from a 5 to 8 volt bias supply, these transistors are also good performers at 2.7 V. Applications include use in wireless systems as an LNA, gain stage, buffer, oscillator, or active mixer. An optimum nois...
