TVS - Diodes

Transient voltage suppressor (TVS) diodes are extensively used to protect sensitive electronic equipment against voltage spikes, such as electrostatic discharges (ESDs), lightning, and induced transient voltages. There is an array of different types and sizes of TVS diodes available being expressly designed for different applications based on their particular requirements.

MAPLAD7.5KP26A TVS-Diode

The MAPLAD7.5KP26A is a 7.5kw (nominal) unidirectional TVS diode designed for either surface mount automotive and commercial applications. It is most often used for the protection of data lines by providing IEC61000-4-2 (ESD) protection up to ±30kV (air-gap discharge). It has an operating temperature range from -55 to +150℃ and is available in the SOT23-6 package, ideal for use with mobile devices, high-speed data storage systems, and touch screens.

Application Field

The MAPLAD7.5KP26A is designed to protect a variety of different on-board and off-board sensitive electronics and components from ESD, lightning, and induced transient voltages. This includes ICs, PLDs, and microprocessors. Additionally, it is especially useful in mobile devices, data storage systems, and touch screens that need to be able to withstand voltage spikes and discharges.

Working Principle

TVS diodes work by providing voltage clamping when triggered by a high voltage so as to limit the voltage spike or surge from reaching essential electronic components. A properly designed TVS diode must be able to dissipate large amounts of energy without exceeding its breakdown rating and then return to its non-conducting state once the spurious voltage has passed.The MAPLAD7.5KP26A is designed to provide bidirectional protection for sensitive electronics by clamping the voltage to less than 7.5KV. At the PN junction, the voltage can swing both directions in order to absorb the energy peaks from ESD, lightning, and transients. The junction capacitance will be effectively accumulated into the clamping voltage and affect the response times.

Conclusion

TVS diodes like the MAPLAD7.5KP26A are used to protect sensitive electronic equipment from transient and surge voltage, such as those found in lightning, ESD, and induced transients. These diodes provide bidirectional protection by clamping the voltage and rapidly returning to their non-conducting state once the voltage passes. Their small design and wide range of operating temperatures make them ideally suited for use in mobile devices, data storage systems, and touch screens.
