AZ23B3V0-E3-08

Overview

The AZ23B3V0-E3-08 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 3.0 V with a tight tolerance of ±2%. The device operates within a test current range of 1 to 5 mA and exhibits a maximum reverse leakage current of 1 µA at 1 V. Dynamic resistance is specified at 95 Ω, while the temperature coefficient ranges from -9 to -3 x 10⁻⁴/°C. Rated for a maximum power dissipation of 300 mW on an FR-4 board, it supports an operating temperature range of -55°C to +150°C and utilizes a compact SOT-23 surface-mount package.

Feature Summary

• Dual common anode configuration for space-efficient circuit integration
• High precision ±2% voltage tolerance for accurate reference applications
• Robust ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant commercial grade construction

Applications

• Precision voltage reference circuits requiring dual channels
• Over-voltage protection in low-power signal lines
• Clamping applications in sensitive analog front-ends

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape-and-reel dimensions and quantity. Confirm RoHS compliance status and material categorization requirements prior to finalizing procurement orders. Ensure that the selected packaging aligns with automated assembly equipment specifications.

Selection Notes

Select this component when a dual-channel solution with high voltage accuracy is required. The ±2% tolerance distinguishes it from standard ±5% variants. Verify thermal management capabilities if operating near the upper temperature limits or under continuous load conditions.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the 'C' series. The 'E3' suffix denotes RoHS compliance, while '-08' specifies the 3000-unit reel packaging format.
