Product Description

The ESD004A5FB is a bidirectional transient voltage suppressor (TVS) designed to protect sensitive electronic devices from transient voltage disturbances such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning strikes. Built on solid-state silicon technology, this device delivers exceptional protection performance and is suitable for a wide range of applications, including mobile communication equipment, portable electronics, and industrial power systems.

Core Features:

  • High protection rating : Supports ESD protection of ±20 kV (air discharge) and ±15 kV (contact discharge) in accordance with IEC 61000‑4‑2, as well as surge current withstand capability of 4.0 A (8/20 μs) under IEC 61000‑4‑5.

  • Key parameters : Reverse breakdown voltage ±5 V (maximum), with a typical clamping voltage as low as 9.0 V (1 A pulse), ensuring fast response and efficient energy absorption.

  • Ultra-low capacitance : 0.3 pF (typical value), minimizing impact on high-speed signal integrity.

  • Compact packaging It employs an SOD-323 package, offering a compact footprint and lightweight design, compatible with high-density PCB layouts, and compliant with lead-free (Pb-free) and halogen-free environmental standards.

Typical applications:

  • Smartphones, tablets, and accessories

  • Portable instruments, digital cameras, in-vehicle audiovisual equipment

  • Laptops, servers, and power supply modules

  • Industrial Control System and Communication Interface Protection

Technical Advantages:

  • Wide operating temperature range (-55°C to 150°C), suitable for harsh environments.

  • Complies with industry standards and delivers reliable long-term stability.

ESD004A5FB, with its high cost-effectiveness and outstanding performance, is the ideal solution for transient voltage protection in portable electronic devices and high-precision systems.
