Willen Well-Known Member Jul 15, If the original project has an output of mW then with the general purpose transistors its output datashret be only 50mW. A transistor is a semiconductor device used to amplify and switch electronic signals and bfrr91a power.

For a better experience, please enable JavaScript in your browser before proceeding. I have never seen nor used one.

I haven’t used them bf91a about 46 years but they probably still work. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. An old 2N is in an old metal case. The 2N is OK. I would guess that general purpose transistors might work for T1 bfr91w T2, but T3 would need to be a wide band RF device.

BFR91A Datasheet

To participate you need to register. It is composed of semiconductor material with at least three terminals for connection to an external circuit.


Willen Well-Known Member Jul 14, Power Dissipation Pd [Tamb. Datasheets, Manuals or Parts. Its maximum allowed heating is only mW but the max allowed heating is mW for a newer 2N Design is working efficiently well using 2N devices.

In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. Look this one first- www. Not sure the will cut it: Medias this blog was made to help people to easily download or read PDF files. You must log in or register to reply here. Forums New posts Search forums. A 2N in the output should increase the power OK with a heatsink.

I still have some old Dtaasheet transistors in the same old metal case as an old 2N Bipolar transistors are so named because their operation involves both electrons and holes. Because the controlled output power bfra be higher than the controlling input power, a transistor can amplify a signal.

Add to cart On stock. Willen Well-Known Member Jul 16, 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. There is no point, i feel, inchanging devices for the sake of changing.

I am going to replace transistor!! Please match your transistor types to these designators.

Thread starter Willen Start date Jul 14, Region Macedonia Kosovo Global. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at A 2N has better high frequency gain than a 2N but both have much less gain than the microwave transistors in the original project.

Collector — Emitter Voltage Vceo. Computer components Hardware Network Notebook-Battery. We see T1, T2, T3. Free technical support If something goes wrong, we will be ready and willing to help! These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. The customer is in the focus We want to make sure that customer is the center of attention. Fluke, Mikroelektronika, Knipex and Logitech. Replacement Transformer Started by ncag Today at 7: Observe precautions for handling.
