JANTX2N7218

The JANTX2N7218 from Infineon is a 100V N-channel power MOSFET qualified to the JANTX reliability level of MIL-PRF-19500, designed specifically for high-reliability switching and power control applications. Housed in a hermetically sealed TO-254 metal package, this device delivers low on-resistance and robust avalanche energy capability, while its 100V drain-source breakdown voltage makes it suitable for a wide range of DC-DC converters, motor drives, and power distribution systems. The JANTX suffix denotes rigorous screening that includes 100% burn-in, thermal cycling, and electrical testing over the full military temperature range, ensuring consistent performance in mission-critical environments.

Typical deployments cover defense and aerospace platforms — including radar power supplies, satellite power management, avionics actuator controls, and weapons systems — where failure is not an option. Procurement engineers value the JANTX2N7218 for its compliance with defense standardization programs, which guarantees form, fit, and function interchangeability across qualified manufacturers. The TO-254 package facilitates direct mounting to heatsinks and PCB integration, while the part’s QPL listing supports long-term program sustainment by minimizing obsolescence risk and counterfeit vulnerability. This device remains a trusted choice when sourcing MIL-spec discrete semiconductors for new designs and legacy system upgrades.
