TVS-Diodes are an expanding electronic component type, first developed in the 1970s. Designed primarily to protect downstream devices from voltage damaging surges, their internal structure means they require a much higher clamping voltage than a regular diode. This component type has seen increasing demand as advances in technology, and specifically microelectronics, have pushed design engineers to build increasingly sensitive downstream devices.

The TVS-Diodes range includes bidirectional, unidirectional and zener solutions. The device type discussed here, the TV02W6V0-HF, is a 16 mm leaded, bidirectional, unidirectional, Transient Voltage Suppressor. Available in 12 different voltage variants (2.2V – 15V), it offers a 600 Watts peak power clamping capability, surge current ratings up to 20A and a peak pulse current rating of up to 43A.

The TV02W6V0-HF provides protection against both transient positive and negative surges, covering a majority of common circuit and micro-electronic circuit protection requirements. Due to its excellent clamping performance, it is usually used to protect valuable equipment and components against electrical damage in AC/DC systems, including:

• Telecommunication Systems: for bonding and grounding
• Consumer Electronics: For Clamping and protecting from leakage and surge current
• Industrial Automation: For protection from ESD
• Medical Equipment: For secure patient connection
• LED Lighting: For protection against board leakage

The TV02W6V0-HF works using the principle of having an internal structure that means it requires a much higher clamping voltage than a regular diode. This is because it contains a combination of zener diodes, avalanche diodes and varimustors. On application of voltage the device quickly disperses the charge, diverting it away from the downstream equipment.

When in static operation, the TV02W6V0-HF device functions as an open circuit. When the voltage exceeds the specified break over (breakdown) voltage, however, it quickly changes to a short circuit. As soon as the voltage drops below the break over voltage again, the device switches back to an open circuit. This sequence takes place in around 5 to 10 nanoseconds.

The Avalanche breakdown mechanism inherent in TV02W6V0-HF is extremely effective at dissipating high levels of surge current. As the device switches, its dynamic impedance increases exponentially, thus clamping and controlling the surge by dissipating the excessive voltage as heat. This results in protection from a huge array of transient surge events.

The TV02W6V0-HF\'s excellent threshold stability, efficiency and price combine to make it a highly desirable option when looking for surge protection. The ability to withstand extreme temperatures, with the device operating perfectly between -55°C and 150°C makes it the go-to choice for a huge range of applications, from communications to medical.

TVS-Diodes, and specifically the TV02W6V0-HF, have proven themselves in the extreme conditions of space, and are the devices of choice for protecting sensitive microelectronic equipment and components, while ensuring a secure connection. The combination of measures they offer.
