Microchip Technology has launched a new family of military-certified transient voltage suppressor devices aimed at safeguarding aerospace and defense electronics against power surges, lightning, and electromagnetic disturbances. Branded as the JANPTX series, the components are designed to clamp sudden voltage spikes before they can harm critical systems, including avionics, sensors, and communication networks. In a departure from traditional military TVS designs housed in metal or ceramic hermetic packages, Microchip’s new devices use plastic packaging while still complying with the MIL-PRF-19500 military specification, enabling lower weight and reduced cost. The surface-mount devices support operating voltages ranging from 5 to 175 volts, handle surge events of up to 1.5 kW, and react in less than 100 picoseconds. Despite their plastic construction, they meet MIL-PRF-19500/716 requirements and relevant IEC standards for ESD, fast transient, and surge protection, with hermetic equivalents available where required. Weighing approximately 0.25 grams, the components are optimized for SWaP-constrained platforms and are now available in volume production, supported by SPICE models to aid design and simulation.
