Michas AVR Transistor tester
Everyone knows the problem: you have a transistor, but you can not read the signature. Or you can not find the datasheet. You have a diode or you have a capacitor, but you can not read ... Here is the solution smarty.

| Michas_AVR-Transistortester |
Features:
* Automatic detection of NPN and PNP transistors, N-and P-channel MOSFET, the diode (including the double diode), thyristor, triac and resistor.
* Automatic pin detection and reporting of test components
* Detect and display protection diode and the MOSFET transistor
* Determination of the amplification factor and the forward base-emitter voltage of transistor
* Measurement of threshold voltage and gate capacitance of MOSFET
* Show the value of the text-LCD (2 × 16)
* One-button operation, automatic shut-off
* Power consumption in off mode: <20 nA
This tester also supports measuring the diode, R / C testing, and many other components identified.

New architecture silicon microwave power transistor
Above is a new architecture of the transistor which is applied in high voltage vertical FET (HVVFET ™) to achieve high operating voltage and very high power packaging density. This approach offers many advantages to designers of power amplifiers.High voltage solutions help designers to simplify the matching circuit discrete devices. Achieving high power through the device causing high voltage impedance level, allows the network to the appropriate circuit with fewer components smaller area. As a result, a series of matching not only the smaller, less expensive solutions, but offers higher reliability as well as there fewer parts with the potential to fail. This circuit is suitable also show less loss than a low impedance solution that has a higher transformation 50 ohm impedance ratio desired.
