Single Zener Diodes Procurement Notes

Verify that the ordering code suffix matches the required reel quantity and tape width specifications. Confirm RoHS compliance status aligns with project requirements. Ensure the component marking code corresponds to the specific voltage grade. Validate that the supplier source is authorized by Vishay to guarantee authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when a precise 24 V reference is needed in a compact footprint. The ±2% tolerance makes it suitable for applications demanding tighter accuracy than standard commercial grades. Consider the thermal resistance values when designing PCB layouts to ensure power dissipation limits are not exceeded under continuous operation.

Single Zener Diodes Part Context

This part belongs to the BZX84 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a wide voltage range from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% tolerance variant, while the '-E3' suffix denotes RoHS compliance. These devices are widely used in general-purpose electronic circuits.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include BZX84C24-E3-18, which offers a wider ±5% tolerance. For automotive applications, consider AEC-Q101 qualified variants such as BZX84B24-HE3_A-18. Verify pinout compatibility and thermal characteristics before substitution.
