Single Zener Diodes Procurement Notes

Verify the specific suffix 'TP' indicates tape-and-reel packaging containing 10,000 pieces per reel. Confirm RoHS compliance status and lead-free finish details directly with the manufacturer or authorized distributors before procurement. Ensure the ordering part number matches the required electrical characteristics and package type.

Single Zener Diodes Selection Notes

Select this component when a 19 V reference is required in a compact axial package. Consider the 500 mW power rating and thermal derating requirements above 50°C. Evaluate the 23 Ohm impedance against circuit sensitivity. Verify that the operating temperature range meets the environmental demands of the target application.
