Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status as this specific part number may not meet current environmental directives. Ensure the ordering suffix matches the required packaging format, such as bulk or tape and reel, to align with assembly requirements.

Single Zener Diodes Selection Notes

Select this component when a 33 V regulation point is required with moderate power handling capabilities. Consider the thermal environment to ensure the 500 mW dissipation limit is not exceeded. Verify that the axial package style fits the available board space and routing constraints compared to surface-mount alternatives.
