• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' against the manufacturer's latest documentation to confirm compliance with current environmental standards, such as RoHS directives. Ensure the DO-213AA package dimensions match the target PCB footprint design constraints. Confirm that the 500 mW power rating aligns with the thermal management capabilities of the intended application environment to prevent overheating during operation.

Single Zener Diodes Selection Notes

Select this component when a 13 V Zener voltage is required with tight ±5% tolerance. The DO-213AA package is suitable for automated surface-mount assembly processes. Consider the 90 ohm impedance value for dynamic regulation requirements. The wide temperature range supports operation in harsh industrial or automotive environments where standard commercial-grade components may fail.
