Semtech RClamp1502B

Ultra-Low Capacitance TVS for ESD and CDE Protection

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
