2N6279

Overview

The Microchip Technology 2N6279 is a silicon NPN power bipolar junction transistor (BJT) designed for high-current applications. It utilizes a TO-3 metal can package to facilitate efficient thermal dissipation and robust mechanical stability. The device supports a maximum collector current of 50 A and withstands a collector-emitter voltage of 150 V. With a maximum power dissipation rating of 250 W, it is engineered for demanding environments operating between -65°C and 200°C junction temperature.

Feature Summary

• High current handling capability suitable for heavy-duty switching and amplification tasks
• Robust metal TO-3 package construction ensuring superior thermal management
• Extended operational temperature range supporting extreme environmental conditions

Applications

• Industrial motor control systems requiring high current drive
• Power supply circuits utilizing series pass regulation
• High-power audio amplifier output stages

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity and traceability. Confirm that the TO-3 package dimensions match your existing thermal interface design. Check for any RoHS compliance status variations as this may affect regulatory adherence in specific regions. Ensure proper handling procedures are followed due to the heavy metal package weight.

Selection Notes

Select this component when designing circuits necessitating substantial continuous collector current alongside high voltage blocking capabilities. The TO-3 package requires compatible mounting hardware and thermal compound for optimal heat transfer. Evaluate the thermal resistance characteristics against your heatsink solution to maintain junction temperatures within safe limits during peak operation cycles.

Part Context

This part belongs to the family of high-power discrete semiconductors manufactured by Microchip Technology. It serves as a rugged alternative to lower-power plastic-packaged transistors in industrial settings. The TO-3 form factor distinguishes it from modern surface-mount devices, offering legacy compatibility for older equipment designs and high-reliability requirements.

Replacement Considerations

Consult official cross-reference lists for direct equivalents such as the 2N6277. Verify pinout compatibility and thermal resistance specifications before substituting. Ensure the replacement device meets or exceeds the original voltage and current ratings.
