The JAN1N6354US/TR is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It features a 180V breakdown voltage and operates with a test current of 0.68mA. The device exhibits a dynamic impedance of 1500 ohms, ensuring stable regulation under specified conditions. Packaged in a surface-mount SQ SMT form factor, it utilizes voidless hermetically sealed glass construction with internal metallurgical bonds for high reliability.
Verify the specific ordering suffix to confirm package type and tolerance levels. Confirm military qualification status if required for your application. Check for RoHS compliance status as these are often non-compliant due to leaded materials. Validate availability through authorized distributors or direct manufacturer channels.
Select this component when hermetic sealing and military-grade reliability are mandatory. Ensure the 180V Zener voltage aligns with circuit requirements. Consider the surface-mount package constraints during PCB layout. Verify thermal management capabilities match the system's power dissipation needs.
This part belongs to the 1N6309 through 1N6355 series of industry-recognized Zener diodes. These components are designed for applications where standard commercial parts lack sufficient reliability. The series offers various voltage selections within a standardized hermetic package format.
Direct substitutes include other military-qualified Zener diodes from the same series with identical voltage ratings. Cross-reference with MIL-PRF-19500/533 specifications to ensure equivalent performance characteristics.
