Overview
The μClamp series of transient voltage suppressor (TVS) arrays are designed to protect sensitive electronics from damage or latch-up due to electrostatic discharge (ESD). They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. Each device will protect one unidirectional line operating at 4.7 volts. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±30kV air) ±30kV (contact discharge).
Features
- Transient protection to:
- IEC 61000-4-2 (ESD): ±30kV (contact), ±30kV (air)
- IEC 61000-4-5 (lighting): 100A (8/20μS)
- Working voltage: 4.7V
- Protects one I/O or power line
- Dynamic resistance: 0.01Ohms (Typ)
- Low ESD clamping voltage
- Solid-state silicon-avalanche technology

Protecting the 24-Volt Direct Current (DC) System – The Backbone of Industry 4.0
Industrial automation is rapidly evolving from rigid, standalone systems into interconnected, intelligent networks that define Industry 4.0. Modern industries are not just automated - they’re hyperconnected with thousands of sensors, controllers and many sophisticated devices. The fusion of digital technologies — particularly the Industrial Internet of Things (IIoT), with its sensor-generated real-time data streams — powers this transformation by facilitating predictive maintenance and dramatically cutting unexpected equipment failures. In the world of modern manufacturing, where precision sensors, complex logic controllers and interconnected devices drive production, there is one constant across multiple architectures – the power source which is a 24-volt direct current (DC) system.

A Growing Crisis Demands Smart Solutions
Spain loses 25% of its water to leaks1. Portugal loses 33%2. Meanwhile, Catalonia's reservoirs have reached historic lows and Portugal's Algarve region has imposed severe restrictions with dams at just 20% capacity.The Iberian Peninsula faces a growing water crisis.
Spain has emerged as a significant adopter of Advanced Metering Infrastructure with LoRaWAN® as the leading choice of IoT connectivity, with over 647,000 LoRaWAN-enabled water meters already deployed—and the European Union (EU) is backing expansion through its Strategic Projects for Economic Recovery and Transformation (PERTE) funding program.

The Smart Water Revolution: How LoRaWAN® is…
The evolution of smart metering has transformed how utilities collect and manage metering and consumption data. At the heart of this digital transformation of utilities lies the wireless M-Bus (wM-Bus) protocol, a wireless communication protocol for automated meter reading that has been adopted for over 20 years through the standard defined by the European Normalization Committee (CEN) under the standard series EN13757, encompassing Europe and beyond. In this blog post, we'll explore our recent demo featuring the Semtech LR1121 and LR2021, and discuss how enabling the dual connectivity for wM-Bus and LoRaWAN® is today’s demand of utilities for Smart Metering.
