Single Zener Diodes Procurement Notes

Verify that the specific suffix CUS/TR corresponds to the required ±2% tolerance and tape-and-reel packaging format. Confirm compliance with MIL-PRF-19500/533 requirements for your procurement specification. Ensure the SQ-MELF footprint matches your PCB design constraints. Validate RoHS exemption status if applicable to your assembly process.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under extreme thermal conditions. The ±2% tolerance offers higher accuracy than standard ±5% variants. The surface-mount SQ-MELF package facilitates automated assembly. Consider the 500 mW power rating for thermal management in dense circuit layouts.

Single Zener Diodes Part Context

This part belongs to the JAN1N6318 series of Zener diodes produced by Microchip Technology. It shares core electrical characteristics with through-hole equivalents like JAN1N6318C but differs in package type. The series covers various Zener voltages from 2.4 V to 6.8 V, providing options for different reference needs within the same military-grade family.

Single Zener Diodes Replacement Considerations

JAN1N6318C serves as a parameter-equivalent through-hole alternative. JANTXV1N6318US offers similar performance in a surface-mount MELF package but may have different tolerance or packaging specifics. Verify pinout and mechanical dimensions before substitution.
