MAX3202EEWS+T TVS - Diodes

MAX3202EEWS+T is a type of transient voltage suppression diode (TVS) developed and manufactured by Maxim Integrated, used for overvoltage protection. It is a three-terminal device with an integrated extended-temperature ESD protection feature, which provides automotive-grade ESD protection for sensitive analog and digital signals. The device is designed to handle differential-mode ESD currents up to 6.5 A and operate over the -40°C to +125°C temperature range.

Application Fields

MAX3202EEWS+T is suitable for protecting vehicle electronics from voltage transients, lightning, and other overvoltage events. The diode has a wide variety of applications in automotive, including infotainment systems, sensors, audio systems, displays, power steering, remote control, and more. It is also used in computers, gaming consoles, and cell phones. The superior ESD protection characteristics of the diode makes it ideal for use in mission-critical applications.

Working Principle

MAX3202EEWS+T is a three-terminal device that works on the principle of avalanche breakdown. The diode has two electrodes; the anode and the gate. When a voltage is applied at the anode, it causes an increase in the current flowing through the diode, resulting in the formation of a depletion region at the junction of the two electrodes. If the voltage is high enough, the electrostatically induced electric field in the depletion region gets so strong that the electrons are accelerated to a point where they gain enough energy to break the covalent bond between the atoms, resulting in an avalanche breakdown.

Once the avalanche breakdown occurs, a large number of charge carriers are produced, which act as minority carriers to the majority diffusion current and reduce the voltage across the diode. This reduces the current flowing through the diode and protects the electronic device against the overvoltage. The diode also features an ESD protection circuit, which helps to protect the device from electrostatic discharges.

Conclusion

MAX3202EEWS+T is a highly reliable TVS diode with excellent ESD protection features, which makes it ideal for use in automotive, computer, and cellular applications. The device is designed to provide overvoltage protection against voltage transients, lightning, and other overvoltage events, and is able to operate over the -40°C to +125°C temperature range. The diode is made of high-grade materials and is manufactured to stringent quality control processes, ensuring its long-term reliability.
