Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'TAP' suffix to confirm the specific ammopack tape configuration. Ensure the required tolerance aligns with the 'B' designation for ±5% accuracy. Confirm compliance with RoHS3 standards and check material categorization documentation for environmental requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 27 V reference is required in an axial through-hole format. The ±5% tolerance suits general-purpose applications where tight precision is not critical. Consider the 500 mW power rating and ensure adequate heat sinking or lead length management to maintain safe operating temperatures during continuous operation.
