Product Introduction

Overview

The SZESD5Z3.3T1G is a unidirectional ESD protection diode from onsemi, designed to protect voltage-sensitive components from electrostatic discharge (ESD) and transient voltage events. This diode is part of the ESD5Z Series, which is renowned for its excellent clamping capability, low leakage, and fast response time. These characteristics make it ideal for ESD protection in designs where board space is limited, such as in cellular phones, portable devices, digital cameras, and power supplies.
