Ultra-Low Capacitance TVS for ESD and CDE Protection

Semtech_RClamp1502B

RailClamps are ultra low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients).

Overview

Features

Transient protection for high-speed data lines to
- IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
- IEC 61000-4-4 (EFT) 40A (5/50ns)

Designed to replace polymer TVS
Protects up to two I/O lines
Ultra-Low capacitance (<1pF)
No insertion loss to >3.0GHz
Low profile (<1mm)
Low leakage current and clamping voltage
Low operating voltage: 15.0V
Solid-state silicon-avalanche technology
