JANTXV2N3811L

Overview

The JANTXV2N3811L is a dual PNP silicon bipolar junction transistor (BJT) manufactured by Microchip Technology, formerly Microsemi. It belongs to the 2N3811 series and is designed for high-reliability applications requiring hermetic sealing. The component features a metal can package configuration suitable for through-hole mounting. Official documentation indicates that this specific part number has reached its end-of-life status, with discontinuance notifications issued by the manufacturer. It is classified as a small-signal device intended for specialized electronic circuits where radiation hardness and environmental stability are critical requirements.

Feature Summary

• Hermetically sealed metal can construction ensuring environmental protection
• Dual PNP transistor configuration within a single package
• Silicon-based semiconductor technology for stable operation
• Designed for high-reliability military or aerospace-grade applications

Applications

• Radiation-hardened electronic systems
• Military-grade signal processing circuits
• Aerospace control modules requiring hermetic sealing

Procurement Notes

This component is officially discontinued and no longer in active production. Verification of authenticity is critical when sourcing from secondary markets due to the potential for obsolete stock. Buyers must confirm the manufacturing date code and physical integrity of the hermetic seal. Supply availability is limited to existing inventory held by distributors or surplus dealers. Compliance with export controls and end-user restrictions may apply given its historical military classification. Procurement should prioritize verified sources offering traceable documentation.

Selection Notes

Engineers replacing this component must evaluate equivalent radiation-hardened dual PNP transistors available from current production lines. Compatibility checks should focus on pinout alignment, voltage ratings, and thermal characteristics within the TO-77 or similar hermetic packages. Since the original part is obsolete, design modifications may be necessary to accommodate alternative form factors or lead configurations. Validation testing under expected operating conditions is recommended to ensure performance parity with the legacy specification.

Part Context

The JANTXV2N3811L represents a specialized variant within the broader 2N3811 family, distinguished by its enhanced reliability standards and hermetic packaging. Manufactured by Microsemi, now part of Microchip Technology, it was historically utilized in defense and space applications. The 'JANTXV' suffix typically denotes a higher grade of quality control and screening compared to commercial equivalents. Its discontinuation reflects shifts in manufacturing focus toward newer technologies while maintaining support for legacy critical systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Engineers should consult Microchip's official obsolescence notices for recommended alternatives or contact the manufacturer directly for qualified replacement options.
