Microchip Technology has introduced a new family of military-qualified surge-protection devices aimed at safeguarding sensitive defense and aerospace electronics from voltage spikes, lightning strikes, and electromagnetic interference. The newly released JANPTX transient voltage suppressor (TVS) series is designed to protect mission-critical systems such as avionics, sensors, power distribution units, and secure communications equipment.
The JANPTX devices absorb sudden electrical transients before they reach vulnerable components, helping prevent system damage and operational failures. Unlike conventional military-grade TVS components that rely on hermetic metal or ceramic packaging, Microchip’s latest solution uses plastic packaging while still meeting the stringent MIL-PRF-19500 military qualification standard.
According to the company, the use of plastic packaging significantly reduces component weight and cost without compromising reliability in harsh operational environments. The surface-mount, unidirectional devices support working voltages ranging from 5 volts to 175 volts and are capable of suppressing transient events of up to 1.5 kilowatts, with response times of less than 100 picoseconds.
Despite their lightweight construction—each device weighs approximately 0.25 grams—the components comply with MIL-PRF-19500/716 and relevant IEC standards for electrostatic discharge, fast transients, and surge immunity. Microchip noted that equivalent hermetic versions are also available for applications requiring traditional packaging. The devices are now in full production and supported by SPICE simulation models, enabling faster design validation for military and aerospace engineers.
