The LC90 Inkjet Cartridges from Microchip Technology Inc., specifically the LC90/TR and LC90A variants, are designed to provide robust protection against transient voltage surges in electronic circuits. These diodes are through-hole components, featuring a DO-13 (DO-202AA) package that makes them easy to integrate into various circuit boards.

If you're working on projects involving inkjet printers, copiers, or any other devices that require reliable power supply protection, these diodes are a go-to choice. They offer a clamp voltage of 160V and can handle an impulse current of 9.4A, making them suitable for protecting sensitive electronics from overvoltage conditions. One thing worth noting is their high surge power rating of 1.5kW, which ensures they can handle significant energy spikes without failing.

Engineers tend to reach for this type of diode when they need a component that can handle both transient voltage surges and high surge power without degrading the performance of the protected circuit. The LC90/TR variant, with its higher clamp voltage and impulse current capability, is particularly useful in more demanding environments where the risk of overvoltage is higher. Overall, these diodes are a solid investment for any project requiring reliable transient voltage suppression.
