2N5312

Overview

The 2N5312 is a PNP bipolar junction transistor manufactured by Microchip Technology. It features a maximum collector current of 5 A and a collector-emitter breakdown voltage of 80 V. The device has a maximum power dissipation rating of 87 W and operates within a junction temperature range of -65 °C to 200 °C. It utilizes a TO-211MA package with stud mounting capabilities.

Feature Summary

• High-power PNP bipolar junction transistor design
• Robust thermal performance for demanding applications
• Stud mount configuration for efficient heat dissipation

Applications

• Power switching circuits
• High-current load driving
• Industrial control systems

Procurement Notes

Verify the specific manufacturer source, as the part number may be associated with multiple entities including Actel or Central Semiconductor in some databases. Confirm the package type matches the required application, as variations exist between TO-211MA and other forms. Ensure compliance with RoHS standards if lead-free components are mandatory for the project.

Selection Notes

Select this component when high current handling up to 5 A and significant power dissipation near 87 W are required. The wide operating temperature range supports extreme environments. Consider the stud mount requirement for mechanical integration and thermal management solutions suitable for high-power BJT applications.

Part Context

This component belongs to the single bipolar transistor category. It is distinct from the 1N5312BK, which is a current regulator diode. The 2N5312 serves as a discrete semiconductor device for power electronics, differing fundamentally from diode-based regulation components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative manufacturers.
