JANTX2N4092UB

Overview

The JANTX2N4092UB is a military-qualified NPN small-signal bipolar junction transistor (BJT) manufactured by Microsemi. It features a hermetically sealed ceramic surface-mount package designed for high-reliability applications. The device operates with a collector-emitter voltage of 30V and supports a continuous collector current of 100mA. Power dissipation is rated at 300mW, ensuring stable performance in compact circuit designs requiring robust signal switching capabilities.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Military qualification under the JANTX reliability standard
• Optimized for high-frequency small-signal switching operations

Applications

• Aerospace communication systems
• Satellite telemetry circuits
• High-reliability radar signal processing

Procurement Notes

Verify the specific manufacturing lot date code and final inspection certificates upon receipt to ensure compliance with military quality standards. Confirm that the component matches the exact JANTX2N4092UB designation, as suffix variations may indicate different testing levels or packaging configurations. Request full traceability documentation from authorized distributors to validate authenticity and prevent counterfeit infiltration.

Selection Notes

Select this component when a hermetically sealed NPN BJT is required for harsh environments where moisture resistance is critical. Ensure the design accommodates the 30V collector-emitter voltage limit and 300mW power dissipation constraints. Verify that the surface-mount footprint aligns with the specified ceramic package dimensions for proper thermal management and mechanical stability.

Part Context

This part belongs to the 2N4092 family of NPN transistors produced by Microsemi. The JANTX level indicates enhanced screening compared to commercial JAN versions, providing higher reliability for defense and space applications. It serves as a ruggedized alternative to standard plastic-packaged small-signal transistors in mission-critical electronics.

Replacement Considerations

Direct substitutes include other JANTX-level NPN small-signal transistors with matching pinouts and electrical ratings. Verify package compatibility before substitution. Cross-reference with MIL-PRF-19500 specifications to ensure equivalent screening levels.
