Single Zener Diodes Procurement Notes

Verify the specific suffix D-1 against official Microchip documentation to confirm exact manufacturing lot specifications and compliance status. Ensure that the required thermal management aligns with the 500 mW power dissipation rating during operation. Confirm package dimensions match the design footprint before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 19 V regulation point is required in harsh environments. The DO-35-2 package facilitates manual assembly or standard through-hole automated processes. Consider the 100 Ohm impedance characteristic for circuit stability requirements. Evaluate the -65 °C to +175 °C range against environmental constraints.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of radiation-hardened or high-reliability Zener diodes produced by Microchip. The series utilizes silicon junction technology optimized for consistent performance under extreme thermal and electrical stress. It serves as a specialized alternative to commercial-grade equivalents in critical infrastructure.
