Microchip Technology announced the release of its JANPTX family of non-hermetic plastic Transient Voltage Suppressor (TVS) devices that meet the MIL-PRF-19500 qualification, offering 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 engineers a lightweight, cost-effective solution without sacrificing stringent military performance requirements. The JANPTX product line is available in voltage ranges from 5V to 175V and includes five variants: JANPTX1N5555UJ, JANPTX1N5558UG, JANPTX1N5629AUJ, JANPTX1N5665AUG, JANPTX1N5907UG and JANPTX1N5907UJ.
With a high peak pulse power rating of 1.5 kW and clamping response times measured at less than 100 picoseconds in internal tests, the JANPTX family is designed to help ensure the safety and reliability of sensitive electronic components in demanding environments. Designed for surface mounting, these unidirectional TVS devices deliver protection against voltage transients such as lightning strikes, electrostatic discharge (ESD), and electrical surges.
Key Features of the TVS Devices
- Surface-mount unidirectional TVS design
- Can suppress transients up to 1,500W at 10/1000 µs
- Capable of clamping transients in less than 100 ps
- Working voltage range: 5V to 175V
- Military qualification: MIL-PRF-19500/716
- Equivalent hermetic packages available for surface mount and thru-hole
- Weight: ~0.25 grams
Development Tools
The JANPTX devices are supported by various SPICE models, which enable the virtual prediction and simulation of a circuit’s behaviour, eliminating the need for time-consuming physical prototyping and redesigns.
