Product Description

The 1SMA5920B TVS Diode is a high-performance SMA5920B Transient Suppressor designed for robust overvoltage protection in demanding environments. This 20kW Surge Protection Diode offers a peak pulse power rating of 20kW (10/1000μs waveform) with a standoff voltage range of 5.5V to 171V, capable of clamping transient voltages up to 274V. Operating within a temperature range of -55°C to +175°C, it directly interfaces with circuits requiring protection against ESD, lightning strikes, and inductive load switching. Ideal for industrial automation, automotive systems, and telecom infrastructure, the diode features ultra-fast response (<1ns) to suppress transients effectively. Its SMA package ensures easy integration into power lines, data interfaces, and communication ports. Key advantages include high surge handling capacity and reliability under extreme conditions, while its limitations involve voltage clamping thresholds specific to predefined ranges.
