Circling the world at 17,000 mph in the International Space Station and measuring radiation levels created by particles travelling at 300,000 kilometres per second 220 miles below on Earth at CERN; Varadis RADFETs have become the radiation measurement technology of choice for some of the worlds most prestigious and innovative organisations.
Varadis - A truly Universal Company.
Varadis is a spin-out company from Tyndall National Institute in Cork, Ireland; a leading European research centre in integrated ICT (Information and Communications Technology) hardware and systems. Varadis is leveraging over 30 years of Tyndall technology development in the radiation monitoring space.
As a result we are now building and selling the worlds’ most effective and dynamic radiation monitoring components, devices and systems to some of the globes most recognised organisations.
The Varadis RADFET is a microelectronic chip, specially engineered to be sensitive to high energy (ionising) radiation. The RADFETs are small, robust, require no power to detect radiation, can easily be integrated into electronic systems, and are cost effective.
Varadis RADFETS are today circling the world at 17,000 mph in the International Space Station and 220 miles below on Earth (and a further 100 metres underground) at CERN, measuring radiation levels created by particles travelling at 300,000 kilometres per second around the Large Hadron Collider.

The Varadis RADFET is a microelectronic chip, specially engineered to be sensitive to high energy (ionising) radiation. The RADFETs are small, robust, require no power to detect radiation, can easily be integrated into electronic systems, and are cost-effective
Varadis RADFET VT01
Six Lead SOT-23 Plastic Package
Our VT01 RADFET is a discrete p-channel MOSFET optimized for radiation sensitivity. The VT01 is plastic packaged and smaller than the ceramic VT02 and it is a great cost-efficient option for high volume orders.
Varadis RADFET VT02
Eight Lead Ceramic Side Braze Package
Like the VT01, our VT02 RADFET is a p-channel MOSFET optimized for radiation sensitivity. The VT02 is a hermetically sealed ceramic package and slightly larger than the plastic version. Please contact us for more details.
Varadis RADFET VT03
Six Lead SOT-23 Plastic Package
Our VT03 RADFET is a discrete p-channel MOSFET that addresses a lower dose range than VT01 and VT02. The VT03 is plastic packaged and smaller than the ceramic packaged VT04 providing a more cost-efficient option.
Varadis RADFET VT04
Eight Lead Ceramic Side Braze Package
Our VT04 RADFET is a discrete p-channel MOSFET optimized for radiation sensitivity. The VT04 addresses lower dose ranges than VT01 and VT02. The VT04 is a hermetically sealed ceramic package and slightly larger than the plastic version VT03.
Varadis RADFET VT05
Six Lead SOT-23 Plastic Package
Our VT05 RADFET is a p-channel MOSFET optimized for radiation sensitivity in higher dose ranges than VT01 and VT02. The VT05 is plastic packaged and smaller than the ceramic VT06 and it is a great cost-efficient option for high volume orders.
Varadis RADFET VT06
Eight Lead Ceramic Side Braze Package
Like VT05 our VT06 RADFET is a p-channel MOSFET optimized for radiation sensitivity in higher dose ranges than VT01 and VT02. The VT06 is a hermetically sealed ceramic package and slightly larger than the plastic equivalent serial number VT05.
