The JANPTX devices meet the MIL-PRF-19500 qualification
Microchip Technology has released its JANPTX family of non-hermetic plastic Transient Voltage Suppressor (TVS) devices that meet the MIL-PRF-19500 qualification, providing high-reliability protection for aerospace and defence applications
These TVS devices are the first in the industry to achieve MIL-PRF-19500 qualification in a plastic package, offering a lightweight solution without sacrificing military performance requirements.
The JANPTX product line is available in voltage ranges from 5V to 175V and includes 84 variants: JANPTX1N5555UJ, JANPTX1N5558UG, JANPTX1N5629AUJ, JANPTX1N5665AUG, JANPTX1N5907UG, and JANPTX1N5907UJ.
The JANPTX family is designed to ensure the safety and reliability of sensitive electronic components in challenging environments, with a high peak pulse power rating of 1.5kW and clamping response times of less than 100ps in internal tests.
Designed for surface mounting, these unidirectional TVS devices can protect against voltage transients, including lightning strikes, electrical surges, and electrostatic discharge (ESD).
Ronan Dillon, associate director of Microchip’s high-reliability and RF business unit, said, “Microchip’s JANPTX family sets a new standard for military-grade transient protection in aerospace and defence. 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.”
The JANPTX TVS devices help safeguard avionics, electrical systems, and other mission-critical applications where low voltage and high reliability are vital. Their design protects against switching transients, induced RF effects, Electromagnetic Pulse (EMP), and secondary lightning events, and meets IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5 standards.
Key features include:
- A working voltage range of 5 to 175V
- A MIL-PRF-19500/716 military qualification
- Surface-mount unidirectional TVS design
- Capable of suppressing transients up to 1,500W at 10/1000 µs
- Weighing 0.25g
- Can clamp transients in under 100ps
- Equivalent hermetic packages available for surface mount and thru-hole
