Microchip Introduces Revolutionary Military-Qualified Plastic TVS Devices
On January 13, 2026, Microchip Technology Inc. (Nasdaq: MCHP) announced the launch of its JANPTX family of non-hermetic plastic Transient Voltage Suppressor (TVS) devices. Designed specifically for aerospace and defense applications, these devices meet the rigorous MIL-PRF-19500 qualification, providing exceptional reliability and protection against voltage transients.
Key Features of the JANPTX TVS Devices
The JANPTX product line distinguishes itself as the first plastic package in the industry to achieve MIL-PRF-19500 qualification, offering engineers a lightweight and cost-effective solution that does not compromise on military-grade performance. The family includes five variants, with voltage ranges spanning from 5V to 175V:
- JANPTX1N5555UJ
- JANPTX1N5558UG
- JANPTX1N5629AUJ
- JANPTX1N5665AUG
- JANPTX1N5907UG
- JANPTX1N5907UJ
High Performance Under Demand
Featuring a peak pulse power rating of 1.5 kW and clamping response times of less than 100 picoseconds, the JANPTX family is engineered to enhance the safety and reliability of sensitive electronic components within challenging environments. These unidirectional TVS devices are suitable for surface mounting and effectively protect against various voltage transients, including lightning strikes and electrostatic discharges (ESD).
Expert Insight
Ronan Dillon, associate director of Microchip’s high-reliability and RF business unit, stated, “Microchip’s JANPTX family sets a new standard for military-grade transient protection in aerospace and defense. By delivering the first MIL-PRF-19500 qualified plastic TVS devices, we enable engineers to achieve high reliability and performance in a lightweight, cost-effective package.”
Comprehensive Protection for Critical Applications
The JANPTX TVS devices are critical for safeguarding airborne avionics, electrical systems, and other mission-critical applications. Their advanced design helps protect against:
- Switching transients
- Induced RF effects
- Electromagnetic Pulse (EMP)
- Secondary lightning events
These devices are compliant with IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5 standards, ensuring robust protection.
Development Tools and Availability
Microchip supports the JANPTX devices with SPICE models, allowing for virtual circuit behavior prediction and simulation, which streamlines the design process. These devices are available in production quantities for purchase directly from Microchip or through authorized distributors worldwide.
