2N5301

Overview

The Microchip Technology 2N5301 is a silicon NPN high-power bipolar junction transistor (BJT) designed for through-hole mounting. It is qualified under MIL-PRF-19500/456 standards, specifically at the JANTX and JANTXV levels. The device utilizes a TO-213AA package to manage thermal dissipation effectively. Key electrical ratings include a collector-emitter voltage of 80 V, a collector-base voltage of 80 V, and an emitter-base voltage of 5 V. It supports a continuous collector current of 8 A with a total power dissipation capacity of 75 W. The component operates within a temperature range from -55°C to +200°C.

Feature Summary

• Qualified for military specifications under MIL-PRF-19500/456 standards
• High power handling capability with 75 W total power dissipation
• Extended operating temperature range up to +200°C
• Robust construction using silicon technology in a TO-213AA package

Applications

• Military-grade power switching circuits
• High-voltage amplifier stages
• Industrial power control systems requiring extended temperature tolerance

Procurement Notes

Verify that the specific order includes the required qualification level, either JANTX or JANTXV, as these designations define the screening and reliability standards per MIL-PRF-19500/456. Confirm the package type is TO-213AA and ensure the supplier provides documentation confirming the silicon NPN construction. Cross-reference the manufacturer part number with official Microchip datasheets to validate authenticity and technical compliance before integration into designs.

Selection Notes

Select this component when designing circuits that demand high current handling and significant power dissipation in harsh environments. The 80 V breakdown voltage and 8 A current rating make it suitable for robust power applications. Consider the TO-213AA package size for adequate heat sinking requirements. Ensure the system can accommodate the wide operating temperature range and verify that the military qualification aligns with project reliability mandates.

Part Context

The 2N5301 belongs to the family of high-power NPN transistors manufactured by Microchip Technology. It is distinct from lower-power signal transistors due to its substantial current and voltage ratings. The device is part of a series qualified to military standards, ensuring higher reliability compared to commercial equivalents. Its primary function is to act as a switch or amplifier in high-energy electronic systems where stability under extreme conditions is critical.

Replacement Considerations

Direct substitutes must match the 80 V, 8 A, 75 W specifications and TO-213AA package. Verify if alternative parts meet the same MIL-PRF-19500/456 qualification levels. Generic replacements may lack the specified temperature range or power handling capabilities.
