JAN1N6338US/TR

Single Zener Diodes Overview

The JAN1N6338US/TR is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It features a nominal Zener voltage of 39 V with a 5% tolerance, tested at a current of 3.2 mA. The device has a maximum power dissipation of 500 mW and a Zener impedance of 55 Ohms. It operates within a temperature range of -65°C to +175°C and utilizes a B-SQ-MELF-2 surface-mount package.

Single Zener Diodes Feature Summary

• Military-grade qualification for high-reliability applications
• Hermetically sealed voidless-glass construction
• Internal metallurgical bond for enhanced stability

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Precision voltage regulation in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging against the official datasheet. Confirm that the JAN level meets all required MIL-PRF-19500/533 standards for your application. Ensure the B-SQ-MELF-2 footprint matches your PCB design constraints before ordering.

Single Zener Diodes Selection Notes

Select this component when a 39 V reference is required in a surface-mount form factor. Compare the 55 Ohm impedance against circuit sensitivity requirements. Verify that the 500 mW power rating accommodates the expected thermal conditions in the final assembly.

Single Zener Diodes Part Context

This part belongs to the 1N6309 through 1N6355 series of hermetically sealed glass Zener diodes. It serves as the surface-mount equivalent to the axial-leaded JEDEC registered versions, providing identical electrical performance in a compact B-SQ-MELF-2 package suitable for automated placement.

Single Zener Diodes Replacement Considerations

The JANS1N6338US/TR offers higher radiation hardness levels. The commercial 1N6338US/TR lacks military qualification. Verify pinout compatibility and package dimensions before substituting.
