Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and tape specifications. Ensure the requested quantity aligns with the minimum packing quantity defined in the datasheet. Confirm RoHS compliance status and any automotive qualification requirements relevant to the target application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener reference is required in a small surface-mount footprint. The 500 mW power rating supports moderate current applications. Verify that the 10 µA leakage current meets system requirements. Compare electrical parameters against alternative packages if board space constraints differ. Ensure operating temperatures remain within the specified -55 °C to +150 °C range.
