AZ23B36-E3-18

Overview

The AZ23B36-E3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 36 V with a tight tolerance of ±2%. The device operates within a test current range of 2 mA to 5 mA and exhibits a maximum reverse leakage current of 50 µA at 27 V. Dynamic resistance is specified at 87 Ω, while the temperature coefficient ranges from 8 to 10 x 10⁻⁴/°C. Designed for surface mount applications in SOT-23 packages, it supports power dissipation up to 500 mW and functions reliably across an operating temperature range of -55°C to +150°C.

Feature Summary

• Dual common anode configuration providing two independent Zener references in a single compact package
• High precision voltage grading with ±2% tolerance for stable reference applications
• Robust ESD protection capability exceeding 8 kV via human body model standards
• RoHS-compliant commercial grade construction suitable for automated surface mount assembly

Applications

• Precision voltage reference circuits requiring dual polarity or split supply rails
• Overvoltage protection stages in sensitive signal processing paths
• Clamping networks for transient suppression in communication interfaces

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status matches project requirements. Validate that the specific ordering suffix corresponds to the desired tape and reel packaging format. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering.

Selection Notes

Select this variant when strict ±2% voltage accuracy is mandatory compared to standard ±5% options. Consider the dual common anode topology for space-constrained designs needing multiple reference points. Evaluate thermal management needs as power dissipation capabilities vary significantly between board-mounted and lead-clamped scenarios.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance grade. The 'E3' suffix denotes RoHS compliance and halogen-free material composition. The '-18' suffix specifies the 10,000-unit tape and reel packaging format on a 13-inch reel.

Replacement Considerations

AZ23B36-E3-08 offers identical electrical characteristics but utilizes 3,000-unit tape and reel packaging. AZ23B36-HE3_A variants provide AEC-Q101 automotive qualification for enhanced reliability in harsh environments.
