2N6246

Overview

The Microchip Technology 2N6246 is a silicon PNP power transistor housed in a hermetically sealed TO-3 metal package. It supports a maximum collector current of 10A and a collector-emitter voltage of 70V. The device features a minimum DC current gain (hFE) of 20 and connects the case to the collector terminal. Designed for high-power applications, it operates within a temperature range of -55°C to +125°C and complies with MIL-SPEC screening standards including JANTX and JANS.

Feature Summary

• Hermetically sealed TO-3 metal construction for environmental protection
• High current handling capability up to 10A continuous operation
• Case connected directly to collector for efficient thermal dissipation
• Qualified for military specifications including JANTX and JANS screening

Applications

• High-power linear regulation circuits
• Industrial motor control systems
• Military-grade power amplification stages
• Heavy-duty switching applications requiring rugged reliability

Procurement Notes

Verify that the specific order includes the required military screening level, such as JANTX or JANS, as these affect qualification status. Confirm lead times for hermetically sealed TO-3 packages, which may differ from standard commercial variants. Ensure compatibility with existing thermal management solutions due to the flange-mount design. Check for compliance with RoHS exemptions if applicable to the specific manufacturing batch.

Selection Notes

Select this component when high current capacity and robust physical packaging are required. The TO-3 form factor provides superior heat dissipation compared to plastic packages. Consider the 70V voltage rating against peak circuit loads. Evaluate the need for hermetic sealing based on environmental exposure. Compare hFE requirements against driver capabilities to ensure adequate base drive current.

Part Context
