1PMT26AT1

TVS (transient voltage suppressors) diodes are special semiconductor devices designed for protecting sensitive electrical components that can be damaged by sudden, brief spikes in an electrical current. The 1PMT26AT1 TVS diode falls into this category of devices and is a widely used unipolar type designed for use in sensitive circuits. This article gives an overview of the 1PMT26AT1 diode’s application field and working principles.

The 1PMT26AT1 diode is designed to be used in sensitive applications, where its low on-state voltage ensures minimal disruption to the connected components. Its fast response time (<1ns) and excellent ESD protection (up to 15kV) make it suitable for use in both high-speed communications, as well as automotive systems. Its low leakage current (<18nA) and fast-switching characteristics allow it to be used in battery-powered devices, where a low forward voltage drop is essential for ensuring long battery life. Additionally, its small size (1.2mm x 0.6mm) and low height (<0.8mm) make it ideal for use in tight spaces.

In terms of working principles, the 1PMT26AT1 diode is an unipolar component, meaning it operates with a single anode and cathode. When a voltage spike or surge is detected, it acts as a protection device, allowing the current to flow through the diode and protecting the primary component from damage. To prevent degradation or destruction of the diode itself, the device has a maximum repetitive peak pulse current rating of 26A. This means that the diode can handle up to 26A of peak current in one pulse, with the current strength gradually decreasing until it reaches its normal state again.

For higher current pulses, the 1PMT26AT1 diode can be paired with other diodes in an array, which allows it to handle more current while maintaining the same level of protection. This is especially useful for automotive applications, where sudden voltage spikes can occur due to fluctuations in electrical systems. By using an array of 1PMT26AT1 diodes, the system can be protected from spikes while maintaining a low profile.

In summary, the 1PMT26AT1 TVS diode is a widely used unipolar protection device that is designed for use in sensitive circuits. Its small size, fast switching capabilities, and low on-state voltage make it ideal for use in high-speed communications and automotive systems, while its array functionality allows it to handle current pulses of up to 26A. Overall, the 1PMT26AT1 diode makes a great choice for any application that needs reliable protection from sudden voltage surges.
