Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required plating finish, as the datasheet indicates distinct suffixes for Tin/Lead or Lead-Free configurations. Confirm the package type aligns with the intended PCB footprint. Ensure the component meets RoHS compliance requirements if applicable to the final assembly standards. Cross-reference the marking code C5231B on the physical device to confirm authenticity against the official datasheet specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 5.1 V reference is required with tight ±5% tolerance. The DO-35 package is suitable for through-hole mounting where higher power handling than surface mount options is needed. Consider the temperature coefficient of ±0.030 %/°C for thermal stability requirements in the operating environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5278B series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a wide voltage range from 2.4 V to 170 V, all sharing the same 500 mW power rating and DO-35 package style. The 'B' suffix specifically denotes the ±5% voltage tolerance variant within this product family.
