Overview
The Microsemi Corporation 2N7227U is a high-reliability N-channel Power MOSFET designed for rugged environments. It features a maximum drain current of 14 A at 25°C and 9 A at 100°C, with a minimum breakdown voltage of 400 V. The device has a maximum on-resistance of 315 mΩ at 25°C and supports a pulse drain current of 56 A. It utilizes a TO-254AA hermetically sealed flange mount package.
Feature Summary
- Hermetically sealed construction for long-term reliability in harsh conditions
- High-voltage capability suitable for demanding power applications
- Low on-resistance for efficient power switching
Applications
- Military and aerospace power systems
- Rugged industrial electronics
- High-reliability DC-DC converters
Procurement Notes
Verify the specific suffix (e.g., JANTXV) to confirm QPL status and exact electrical tolerances. Ensure the procurement documentation matches the required MIL-PRF-19500/592 specification level. Confirm package integrity and lead finish upon receipt to maintain hermetic seal performance.
Selection Notes
Select this component when high voltage isolation and extreme environmental durability are required. The TO-254AA package facilitates direct mounting to heat sinks. Verify thermal management requirements against the 14 A continuous current rating and 56 A pulsed current limits.
Part Context
This part belongs to Semicoa's high-reliability MOSFET family, originally developed under the 2N7227 designation. It serves as a radiation-hardened and shock-resistant alternative to standard commercial MOSFETs, ensuring stable operation in defense and space-grade equipment where failure is not an option.
Replacement Considerations
Direct substitutes include JANTX2N7227 and JANTXV2N7227. Verify that replacement units meet the same MIL-PRF-19500/592 qualification standards to ensure compatibility with existing system designs.
