BFR91A Datasheet, PDF – Alldatasheet

Willen Well-Known Member Jul 15, A transistor is a semiconductor device used to amplify and switch electronic signals and bfrr91a power. Collector — Base Voltage Vcbo. Welcome to our site!

These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. The original circuit used good high frequency transistors but you are using ordinary “general purpose” transistors that might melt with a supply that is as high as 12V. Potentiometer Questions Started by norbss Yesterday at Willen Well-Known Member Jul 14, Collector — Emitter Voltage Vceo. Because the controlled output power bfra be higher than the controlling input power, a transistor can amplify a signal.

Please warn me if doing wrong!

The customer is in the focus We want to make sure that customer is the center of attention. Add to cart On stock. It is composed of semiconductor material with at least three terminals for connection to an external circuit.

Design is working efficiently well using 2N devices. Forums New posts Search forums. For a better experience, please enable JavaScript in your browser before proceeding. Bipolar transistors are so named because their operation involves both electrons and holes. Free technical support If something goes wrong, we will be ready and willing to help!

I would guess that general purpose transistors might work for T1 and T2, but T3 would need to be a wide band RF device.
