PESD1USB30Z Circuit Protection

The PESD1USB30Z device is a part of the series of transient voltage suppressors (TVS) that are designed to protect sensitive electronics from electrical overstress. They are commonly used to provide protection for digital electronics, LEDs and electrical sensors. This device is a low-capacitance TVS diode which can provide an ESD protection level of up to 15kV (air and contact discharge).

The purpose of the PESD1USB30Z device is to protect sensitive electronic equipment from ESD pulses occurring in the environment. It works by absorbing the transient voltage pulse associated with an ESD event and limiting the voltage to a safe level. The PESD1USB30Z device is specifically designed for USB 3.0 applications and it can provide up to 30V of protection for ESD pulses. The device also has a low capacitance of 0.30pF to minimize signal distortion.

The PESD1USB30Z device is constructed from two oppositely facing zener diodes with a low capacitance metal oxide varistor (MOV) between them. Each zener diode has a breakdown voltage of 15V and they are connected in series so that the total breakdown voltage of the device is 30V. The MOV protects the device from pulses up to 15kV and it also helps to reduce the capacitance to the circuit.

The PESD1USB30Z device is ideal for applications such as USB 3.0 ports, phones, cameras, medical equipment and automotive electronics. The device can provide protection from a variety of ESD induced voltages including ground-to-ground, line-to-ground, and air-to-ground discharges. It is housed in a small SOT-23 package and requires no external components for operation, making it easy to use and integrate into existing designs.

In summary, the PESD1USB30Z device is a TVS diode specifically designed for protection of USB 3.0 applications from electrical overstress. It offers protection from ESD pulses of up to 15kV, with a low capacitance and voltage limiting of 30V. The device is housed in a SOT-23 package and requires no external components, making it an easy to use and integrate solution for protecting sensitive electronics from ESD related damage.
