Overview
The JANTX2N3811 is a military-grade N-channel junction field-effect transistor (JFET) designed for high-reliability applications. It features a single-gate structure with low noise characteristics and high input impedance. Key electrical parameters include a drain-source breakdown voltage (BV_DSS) of at least 25 V, a gate-source cutoff voltage (V_GS(off)) ranging from -0.5 V to -6 V, and a maximum drain current (I_D) of 10 mA. The device operates within a temperature range of -55°C to +125°C and utilizes a hermetically sealed TO-92 package to ensure environmental stability.
Feature Summary
- Hermetically sealed construction for radiation and moisture resistance
- Low noise performance suitable for sensitive signal processing
- High input impedance minimizing circuit loading effects
Applications
- Military radar systems
- Spacecraft instrumentation
- High-fidelity audio preamplifiers
- Precision measurement equipment
Procurement Notes
Verify the component's authenticity through authorized distributors or direct manufacturer channels. Ensure the part number suffix matches the specific military qualification requirements. Request detailed test reports and traceability documentation to confirm compliance with specified electrical limits and environmental standards before integration into critical systems.
Selection Notes
Select this component when military-grade reliability and hermetic sealing are mandatory. Compare the V_GS(off) spread against circuit biasing requirements to ensure proper operation across the full temperature range. Verify that the TO-92 package dimensions fit the available board space and thermal management constraints.
Part Context
This part belongs to the 2N3811 family of N-channel JFETs. The JANTX prefix indicates it meets strict military screening and quality assurance standards. It serves as a ruggedized alternative to commercial variants, offering enhanced durability for defense and aerospace environments where standard components may fail due to harsh conditions.
