AZ23B36-G3-18

Overview

The AZ23B36-G3-18 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 provides two independent Zener elements with a nominal voltage of 36 V and a tight tolerance of ±2%. The device operates at a test current of 2 mA and dissipates up to 300 mW on standard FR-4 boards. Electrical characteristics include a maximum reverse leakage current of 50 nA and a dynamic resistance of 87 Ω at 1 kHz.

Feature Summary

• Dual common anode configuration for compact circuit integration
• Tight voltage tolerance of ±2% for precision regulation
• High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Green commercial grade construction compliant with RoHS standards

Applications

• Voltage reference circuits requiring precise dual rails
• Transient voltage suppression in signal conditioning paths
• Over-voltage protection for sensitive input stages

Procurement Notes

Verify the specific ordering suffix -18 against project requirements to confirm the 10,000-unit reel packaging format. Ensure that the ±2% tolerance designation 'B' aligns with the design's voltage accuracy specifications before finalizing procurement documentation.

Selection Notes

Select this component when a dual Zener array with high voltage precision is required in a minimal footprint. The 36 V nominal rating suits applications needing stable references above standard logic levels. Verify thermal management capabilities if operating near the 300 mW dissipation limit on standard PCB footprints.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V in both ±5% and ±2% tolerances. The AZ23B36 variant specifically targets applications demanding tighter voltage control than the standard C-series parts.

Replacement Considerations

AZ23C36-G3-18: Offers identical physical form factor and pinout but features a wider ±5% voltage tolerance instead of ±2%.
