Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape and reel specifications. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the part number with the latest datasheet revision to validate compliance with current environmental standards before finalizing purchase orders.

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a compact footprint. The ±2% tolerance makes it suitable for applications where standard commercial grade parts lack sufficient precision. Consider the thermal resistance characteristics and operating temperature range to ensure reliable performance under expected load conditions and ambient environments.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes produced by Vishay Semiconductors. The series offers a wide range of standardized Zener voltages graded according to the international E24 standard. The 'B' designation indicates the tighter ±2% tolerance variant, distinguishing it from the standard ±5% 'C' tolerance devices within the same family.
