The M15KP90 series from Microchip Technology Inc. consists of uni- and bi-directional transient voltage suppressors (TVS) designed for voltage suppression up to 90V. These devices are commonly used in electronic circuits to protect against voltage spikes and surges that could damage sensitive components.

If you're working on power supply designs or any system that deals with input voltages subject to fluctuations, these TVS diodes can be a reliable choice. They offer fast response times and low clamping voltages, making them effective in limiting the impact of transient events. One thing worth noting is their bidirectional capability; they work equally well in both directions, which simplifies design for many applications.

Engineers tend to reach for this when they need robust protection without adding too much bulk or complexity to their design. The M15KP90 series is particularly useful in automotive, industrial, and consumer electronics where transient overvoltages are common but space is often limited. Their small footprint and high surge current ratings make them a popular option for protecting microcontrollers, sensors, and other critical components.
