TVS - Diodes

Transient Voltage Suppression (TVS) diodes are designed to protect sensitive electronic equipment from voltage transients caused by lightning, electrostatic discharge, or other events. The PESD36VS1UJX is an automotive grade switchmode protection device that offers very low leakage current (<50nA) and excellent performance in high speed automotive applications.

Application Field

The PESD36VS1UJX offers excellent ESD protection in automotive environment, making it ideal for use in engine, transmission, body control and infotainment systems. It is also widely used in high speed data lines, CAN bus and in-car Wi-Fi networks, to protect the system from voltage surges, spikes, and ESD events. Besides, this device is suitable for protecting ADSL applications and other communication lines.

Working Principle

This device works by clamping voltage transients through the avalanche breakdown effect. When an over voltage transient is applied to it, carriers are generated in the high field region and start to produce a plasma-like current. This current is proportional to the applied voltage and acts like a voltage clamp. By this mechanism, the transient voltage can be reduced to a safe level without damaging the protected IC. Besides, it also offers very low propagation delay (< 2ns) and low capacitance (< 0.2pF) to ensure excellent signal integrity in high speed networks.

In addition, the PESD36VS1UJX has a low breakdown voltage of 24V and provides protection up to 36V. It is also able to dissipate up to 600W of surge power with a low dynamic resistance (Rdyn) of 0.3Ω. All these features make it ideal for protecting ICs from ESD noise and other transient voltages.

The PESD36VS1UJX is an excellent device to protect sensitive electronic equipment from voltage transients and ESD events. It can be used in a wide range of automotive and communication applications to ensure flawless operation of the system.
