FETtest has over two decades' experience producing high-quality test systems for discrete semiconductors. Our systems address a complete range of semiconductor devices including FETs, BiPolar devices, Diodes, SCRs, PUTs, etc.
Indeed, the capabilities of our systems go well beyond testing field effect transistors - most systems are used to test bipolar devices.
From diodes and transistors to power converters and switches, FETtest systems are in continuous use for production, test, inspection,
characterization, final test and wafer probing applications.
