AZ23B5V1-G3-08

Overview

The AZ23B5V1-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 5.1 V with a tight ±2 % tolerance, indicated by the 'B' designation. The device operates at a test current of 5 mA and dissipates up to 300 mW on FR-4 boards. Electrical characteristics include a maximum reverse leakage current of 2 µA and a dynamic resistance of 60 Ω at 1 kHz. It supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• Tight ±2 % Zener voltage tolerance for precision regulation
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• Lead-free construction compliant with RoHS standards

Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• Signal clamping applications

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm reel size and tape specifications. Confirm that the component meets all required environmental and material compliance standards for the intended application before finalizing procurement.

Selection Notes

Select this part when a dual Zener array with high voltage accuracy is required. The ±2 % tolerance distinguishes it from standard ±5 % variants. Ensure the thermal management design accommodates the specified power dissipation limits under expected ambient conditions.
