JANTX1N6334CUS/TR

Single Zener Diodes Overview

The JANTX1N6334CUS/TR is a surface-mount Zener diode manufactured by Microchip Technology. It provides a nominal regulation voltage of 27 V with a maximum power dissipation of 500 mW. The device features a tight tolerance of ±2% and operates within a junction temperature range of -65°C to 175°C. Electrical characteristics include a reverse leakage current of 50 nA at 21 V and a forward voltage of 1.4 V at 1 A. The component utilizes the SQ-MELF (B) package for compact integration.

Single Zener Diodes Feature Summary

• Surface-mount construction in an SQ-MELF (B) package
• High-temperature operation up to 175°C junction temperature
• Tight voltage tolerance of ±2%
• Designed for critical applications requiring high reliability

Single Zener Diodes Applications

• Voltage regulation in aerospace systems
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging, as standard variants may differ. Confirm RoHS exemption status, as military-grade parts often lack compliance. Ensure the SQ-MELF footprint matches the design layout. Validate the ±2% tolerance requirement against circuit specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when surface-mount technology is required for Zener regulation. The ±2% tolerance offers higher precision than standard ±5% variants. The extended temperature range supports operation in extreme thermal conditions. Verify compatibility with automated placement equipment due to the small SQ-MELF form factor.
