2N6374

Overview

The Microchip Technology 2N6374 is a single-element NPN silicon power bipolar transistor housed in a hermetically sealed TO-66 metal flange mount package. It supports a maximum collector current of 6A and a collector-emitter breakdown voltage of 50V. The device features a minimum DC current gain (hFE) of 20 and operates within a junction temperature range of -65°C to +200°C. With a thermal resistance of 4.3°C/W, it is designed for high-power applications requiring robust performance.

Feature Summary

• Hermetically sealed TO-66 metal package for environmental protection
• High collector current capacity of 6A
• Wide operating junction temperature range up to +200°C
• Low collector saturation voltage characteristics

Applications

• High-power switching circuits
• Wide-band amplifier designs
• Industrial control systems

Procurement Notes

Verify the specific manufacturer source, as the 2N6374 designation is utilized by multiple vendors including Semelab and Central Semiconductor. Confirm that the received component matches the required electrical specifications and package dimensions. Ensure compliance with relevant environmental standards if RoHS compliance is mandatory for the application.

Selection Notes

Select this component for applications requiring a rugged, hermetically sealed NPN power transistor. The TO-66 package facilitates efficient heat dissipation through the flange mount. Consider the 50V rating and 6A current limit when designing the circuit. Verify thermal management requirements against the 4.3°C/W junction-to-case thermal resistance.

Part Context

The 2N6374 belongs to the family of standard military-grade or high-reliability NPN power transistors. It is commonly grouped with similar devices like the 2N6372 and 2N6373. The TO-66 package is a legacy standard often used in aerospace and defense electronics where hermetic sealing is critical for long-term reliability.

Replacement Considerations

Direct substitutes include the 2N6372 and 2N6373 from compatible manufacturers. Cross-reference with Central Semiconductor Corp. or Semelab variants to ensure pinout compatibility and identical electrical ratings before integration.
