Overview
The Microsemi Corporation JANTXV2N6249 is a military-grade NPN power silicon transistor qualified to MIL-PRF-19500/461. It features a maximum collector-emitter voltage (Vceo) of 80 V and a continuous collector current (Ic) of 10 A at case temperature. The device operates within a junction temperature range of -55°C to +175°C. Key electrical parameters include a DC current gain (hFE) ranging from 20 to 100, a collector cutoff current (Iceo) of 5 mA maximum, and a transition frequency (fT) of 3 MHz minimum. Power dissipation is rated at 125 W at case temperature.
Feature Summary
- Military qualification per MIL-PRF-19500/461 for high reliability applications
- High power handling capability with 10 A continuous collector current
- Extended operating temperature range suitable for harsh environments
Applications
- Military radar systems
- Aviation ground support equipment
- High-reliability industrial power amplifiers
Procurement Notes
Verify the specific suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and testing levels. Confirm that the component meets the required MIL-PRF-19500/461 specification level. Check for obsolescence status or last-time buy notices as this is a legacy military part. Ensure proper handling procedures are followed due to the TO-3 metal can package.
Selection Notes
Select this component when military-grade reliability and high current capacity are required. Compare hFE ranges and thermal resistance values against system requirements. Consider the TO-3 package size and mounting constraints. Evaluate alternative NPN power transistors if lower voltage ratings suffice. Verify compatibility with existing drive circuitry for base current requirements.
Part Context
The JANTXV2N6249 belongs to the 2N62xx series of high-power NPN silicon transistors manufactured by Microsemi Corporation. These devices are designed for demanding applications requiring robust performance under extreme conditions. The series is characterized by its military qualification and ability to handle significant power dissipation in a rugged metal can package.
Replacement Considerations
Direct replacements may include other military-qualified NPN power transistors meeting MIL-PRF-19500/461. Verify pinout compatibility and thermal characteristics before substitution. Commercial equivalents may lack the necessary reliability standards for military use.
