AZ23C15-E3-08

Overview

The AZ23C15-E3-08 is a silicon planar Zener diode from Vishay Semiconductors, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 15 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and includes ESD protection exceeding 8 kV (HBM) and 800 V (MM). Packaged in reels of 3000 units, it utilizes a common anode configuration for dual-diode applications.

Feature Summary

• Silicon planar construction with graded Zener voltages according to the international E24 standard
• ESD capability compliant with AEC-Q101 standards for robustness
• RoHS-compliant commercial grade material categorization

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific ordering code suffix against project requirements before procurement. Confirm that the commercial grade designation meets environmental specifications. Ensure the reel quantity aligns with manufacturing volume needs. Validate RoHS compliance documentation for regulatory adherence. Cross-reference the manufacturer part number with distributor listings to ensure authenticity.

Selection Notes

Select this component when a 15 V Zener voltage with ±5% tolerance is required in a compact SOT-23 footprint. Consider the 300 mW power rating on FR-4 boards for thermal management. Evaluate the common anode configuration suitability for the circuit topology. Verify operating temperature range compatibility with the intended environment.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of Zener voltages from 2.2 V to 75 V in the same SOT-23 package family. The 'C' designation indicates the standard ±5% voltage tolerance available in this product line.

Replacement Considerations

Direct replacements include other AZ23 series variants with identical packaging but different voltage ratings. Alternative manufacturers may offer functionally equivalent Zener diodes in SOT-23 packages, though electrical parameters must be verified against the original datasheet specifications.
