Microchip Technology has expanded its military electronics portfolio with the launch of a new range of plastic-packaged, military-certified surge-protection devices designed for use in demanding defense and aerospace environments. The JANPTX TVS product family is engineered to protect sensitive electronics from damaging electrical surges caused by lightning, power fluctuations, and electromagnetic interference.
The transient voltage suppressors act by diverting excess energy away from critical circuits, ensuring continued operation of systems such as avionics, radar sensors, electronic warfare equipment, and military communications platforms. While most military-grade TVS devices rely on heavy hermetic enclosures, Microchip’s new offering delivers full compliance with MIL-PRF-19500 requirements using a lightweight plastic package.
Microchip stated that the design supports size, weight, and power (SWaP)-constrained platforms, making it well suited for modern military aircraft, unmanned systems, and advanced electronic subsystems. The surface-mount devices operate across a 5V to 175V range, suppress surge events up to 1.5 kW, and react in under 100 picoseconds, providing near-instantaneous protection.
Although constructed in plastic, the devices meet MIL-PRF-19500/716 as well as IEC standards for ESD, surge, and fast transient immunity. For customers requiring legacy packaging, Microchip continues to offer hermetic equivalents. The new surge protectors are available immediately in production quantities and include SPICE models to support virtual circuit simulation, reducing development time for defense and aerospace system designers.
