JANTX2N4854

Overview

The JANTX2N4854 is a silicon dual small-signal bipolar junction transistor (BJT) manufactured by Microchip Technology. It features an NPN/PNP complementary configuration housed in a TO-78-6 hermetic package designed for through-hole mounting. The device supports a maximum DC collector current of 600 mA and operates with a collector-emitter voltage (VCEO) of 40 V, a collector-base voltage (VCBO) of 60 V, and an emitter-base voltage (VEBO) of 5 V. Power dissipation is rated at 2 W, allowing operation within a temperature range of -65°C to +200°C. The component exhibits a collector-emitter saturation voltage of 400 mV, with a DC current gain (hFE) ranging from a minimum of 60 to a maximum of 300.

Feature Summary

• Dual complementary NPN and PNP transistors integrated into a single hermetic package
• High thermal stability enabling operation up to +200°C junction temperature
• Military-grade qualification ensuring reliability in harsh environments

Applications

• Military aerospace electronic systems requiring radiation-hardened or high-reliability components
• Harsh environment signal processing circuits
• Industrial control systems operating under extreme thermal conditions

Procurement Notes

Verify the specific revision level and lot traceability documentation upon order confirmation. Ensure that the procurement channel provides valid military compliance certificates. Confirm that the TO-78-6 package dimensions match the design constraints. Validate that the supplier can provide necessary export control classifications if applicable.

Selection Notes

Select this component when a compact dual BJT solution is required for high-temperature applications. Compare the 2 W power dissipation rating against the circuit's thermal requirements. Verify that the 600 mA current limit meets the load demands. Consider the TO-78-6 footprint compatibility during the PCB layout phase.

Part Context

This part belongs to the 2N4854 series of dual small-signal transistors produced by Microchip Technology. It serves as a specialized variant within the company's broad portfolio of discrete semiconductors. The series is engineered to meet stringent performance standards for critical electronic applications.

Replacement Considerations

The JAN2N4854U/TR is a surface-mount alternative in a U-6 package with lower power dissipation. The standard 2N4854 offers identical electrical characteristics but lacks the TX military grade designation.
