2N6038 PBFREE

Overview

The 2N6038 PBFREE is a silicon NPN Darlington power transistor manufactured by Central Semiconductor Corp. It features a maximum collector current of 4A and a collector-emitter sustaining voltage of 60V. The device supports a maximum power dissipation of 40W and operates within a junction temperature range of -65°C to 150°C. It utilizes a TO-225AA (TO-126-3) through-hole package and has a transition frequency of 25MHz.

Feature Summary

• Monolithic construction with built-in forward biased second breakdown current capability
• High current gain typical of Darlington configuration for efficient drive requirements

Applications

• Power switching applications requiring high current handling
• Linear amplifier circuits utilizing Darlington topology
• Industrial control systems operating at elevated temperatures

Procurement Notes

Verify the specific datasheet version from Central Semiconductor Corp or authorized distributors to confirm electrical characteristics, as specifications may vary between manufacturers using this part number. Ensure the PBFREE suffix is included for lead-free compliance if required by assembly processes. Cross-reference with onsemi data sheets for complementary device matching if used in push-pull configurations.

Selection Notes

Select this component when a high-gain NPN power transistor is needed for currents up to 4A. Consider the 60V voltage rating against circuit peak voltages. The TO-225 package requires appropriate thermal management due to 40W dissipation capabilities. Verify compatibility with driving circuitry given the Darlington structure's higher saturation voltage compared to single-transistor designs.

Part Context

This part belongs to a family of plastic Darlington complementary silicon power transistors. It serves as the NPN counterpart to PNP devices such as the 2N6037. The series includes variants with different voltage ratings like the 2N6035 and 2N6039, allowing designers to select based on specific voltage requirements while maintaining similar current and thermal characteristics.

Replacement Considerations

Direct substitutes include the 2N6038 from onsemi. Designers should verify pinout compatibility and exact voltage ratings, as other family members like the 2N6035 offer lower voltage ratings (40V). Ensure thermal resistance values match the application's heat sinking strategy.
