series introduction

# PESD12VS1ULD Product Series Introduction

## 1. Overview
The PESD12VS1ULD product series is a cutting - edge range of protection devices designed to safeguard sensitive electronic circuits from the detrimental effects of electrostatic discharge (ESD), electrical fast transients (EFT), and other overvoltage events. These devices are engineered with advanced semiconductor technology to provide high - performance protection in a compact and efficient package, making them an ideal choice for a wide variety of applications in the electronics industry.

## 2. Key Features

### 2.1 High - Speed Response
One of the standout features of the PESD12VS1ULD series is its extremely fast response time. It can detect and clamp ESD events within nanoseconds, ensuring that the protected circuit is shielded from the potentially damaging high - voltage spikes associated with electrostatic discharge. This rapid response is crucial for protecting modern high - speed electronic components, such as those found in communication interfaces, where even a brief overvoltage can cause data corruption or permanent damage.

### 2.2 Low Capacitance
The series exhibits very low capacitance values. Low capacitance is essential in high - frequency applications as it minimizes signal distortion and attenuation. For example, in high - speed data lines like USB 3.0, HDMI, and Ethernet, the low capacitance of the PESD12VS1ULD devices allows for the smooth transmission of high - frequency signals without significant degradation, ensuring reliable data transfer.

### 2.3 Low Leakage Current
The PESD12VS1ULD devices have extremely low leakage current. This is important because excessive leakage current can cause power consumption issues, especially in battery - powered devices. By maintaining a low leakage current, these protection devices help to extend the battery life of portable electronics such as smartphones, tablets, and wearables, while also ensuring the stability of the protected circuit under normal operating conditions.

### 2.4 High ESD Protection Level
These devices are capable of withstanding high levels of ESD. They are typically rated to handle ESD strikes of up to ±15 kV (air discharge) and ±8 kV (contact discharge) according to the IEC 61000 - 4 - 2 standard. This high - level protection makes them suitable for use in environments where ESD is a common threat, such as industrial settings, consumer electronics manufacturing facilities, and areas with high levels of human activity.

### 2.5 Compact Package
The PESD12VS1ULD series is available in a compact and surface - mount package. The small form factor allows for easy integration into printed circuit boards (PCBs), especially in space - constrained applications. This makes it possible to add ESD protection to a wide range of electronic devices without significantly increasing the overall size of the PCB.

## 3. Technical Specifications

### 3.1 Electrical Characteristics
- **Working Voltage (Vrwm)**: The maximum continuous DC voltage that the device can withstand without significant leakage. For the PESD12VS1ULD series, the working voltage is typically 12 V, which makes it suitable for protecting circuits operating at this voltage level.
- **Breakdown Voltage (Vbr)**: This is the voltage at which the device starts to conduct current in the reverse direction. The breakdown voltage of the PESD12VS1ULD devices is carefully specified to ensure reliable protection while minimizing false triggering under normal operating conditions.
- **Clamping Voltage (Vc)**: When an overvoltage event occurs, the device quickly clamps the voltage to a safe level. The clamping voltage of the PESD12VS1ULD series is designed to be low enough to protect the sensitive components in the circuit from damage.
