Single Zener Diodes Procurement Notes

Verify component authenticity by checking for the 'C' prefix followed by the full part number or the specific marking code on the device body. Confirm that the ordering suffix 'BK' corresponds to bulk packaging and 'PBFREE' indicates lead-free soldering compliance. Ensure the requested quantity aligns with manufacturer minimum order requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an 11 V reference is required in a standard DO-35 axial package. The ±5% tolerance suits general-purpose regulation tasks. Verify that the 500 mW power dissipation rating meets the thermal design constraints of the target application environment.

Single Zener Diodes Part Context

This device belongs to the 1N5221B through 1N5278B series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 2.4 V to 170 V, all housed in the DO-35 case. The 'B' suffix specifically denotes the ±5% voltage tolerance variant within this product family.
