SurgeSwitch™ protection devices are designed to provide high energy EOS protection with superior clamping and temperature characteristics when compared to standard TVS devices. The device uses a surge rated FET as the main protection element. During an EOS event, transient voltage increases beyond the rated breakdown voltage of the device. The FET in turn switches on and conducts transient current to ground. The TDS clamping voltage is nearly constant across the rated peak pulse current range due to the extremely low ON Resistance of the FET. Lower clamping voltage at maximum peak pulse current makes them more suitable for protecting today's sensitive IC's, when compared to standard TVS diodes. TDS1821PW is designed to protect voltage bus or data lines with an operating voltage of 18V. It is rated for a high-energy transient current up to 27A (tp = 8/20μs) and may be used to meet the common industrial voltage surge standard of ±1kV per IEC 61000-4-5 (RS = 42Ω, CS= 0.5μF). TDS1821PW is in a small DFN 1.6 x 1.0 x 0.55mm 2-Lead package and represents significant board space savings over traditional ESD and EOS protection devices.功能

Linear pluggable optics (LPO) is one of the most significant shifts in data center optical interconnect design in a decade — but the term still causes confusion. Is it a module type? A standard? A replacement for digital signal processing function or DSP-based optics entirely? This post answers those questions from first principles.

The USB Type-C connector has become the universal interface of modern electronics. From laptops and smartphones to Artificial Intelligence (AI) computing platforms and industrial edge devices, USB Type-C supports both high-speed data transfer and high-wattage power delivery through a single cable. With the adoption of USB Power Delivery (USB PD) 3.1 and its Extended Power Range (EPR), (Table 1) VBUS line voltages have scaled from the familiar 20V/100W standard power range to 28V, 36V and 48V — enabling power delivery of up to 240W over a USB-C cable.

Buildings are among the world's largest consumers of energy and one of their most underleveraged sources of operational intelligence. According to the International Energy Agency, the building sector accounts for roughly 30% of global final energy consumption and nearly 26% of global energy-related emissions. Yet the vast majority of the world's existing building stock — the millions of offices, hospitals, factories, warehouses, schools, and retail spaces that people occupy every day — remains largely unconnected. Heating runs on fixed schedules rather than occupancy. Leaks go undetected for weeks. Equipment fails without warning. Space sits unused while teams compete for meeting rooms.
