Safe Circuits Thanks to Protection Diodes

ESD protection diodes quickly and effectively protect sensitive circuits

An ESD protection diode (ESD – Electrostatic Discharge diode) is a semiconductor component used to protect electronic circuits from overvoltage and electrostatic discharge. Thanks to its fast response, it limits the voltage to a safe level, protecting sensitive components such as microcontrollers, processors, memory modules, and communication interfaces.

The PESD series from JGSemi includes diodes with various operating voltages, different peak power ratings, and surge current capacities, available in both unidirectional and bidirectional versions. This allows flexible adaptation to a wide range of electronic circuits.

Key Features

• Overvoltage and ESD protection – effectively protects power and signal lines.
• Fast response – reaction time in nanoseconds, protecting sensitive circuits.
• Various operating voltages – from 3.3V to 24V, suitable for standard electronic systems.
• High peak power and surge current – ensures reliable protection during sudden voltage spikes.
• Unidirectional and bidirectional versions – allow protection of both power and data lines.
• Small SMD packages – ideal for compact and modern PCB designs.

Typical Applications

• Protection of data circuits and communication interfaces (USB, HDMI, Ethernet, UART).
• Power supply protection in low-voltage and medium-voltage circuits.
• Consumer electronics, industrial electronics, automotive systems, and IoT devices.
• Battery systems, DC/DC converters, and switching circuits.
• Installations where electrostatic discharge or sudden voltage spikes may damage components.

Summary
The JGSemi PESD series consists of universal and reliable ESD protection diodes that provide fast voltage clamping and effective protection for sensitive electronic circuits. Thanks to a wide range of voltages, currents, and directional versions, they are an ideal solution for designs requiring high reliability and protection against overvoltage.
