Overview
The AZ23B3V3-E3-08 is a dual common anode silicon planar Zener diode array from Vishay Semiconductors. It features a nominal Zener voltage of 3.3 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 5 μA at 3 V. Dynamic resistance is specified at 95 Ω, with a temperature coefficient ranging from -8 to -3 x 10⁻⁴/°C. It is housed in a compact SOT-23 package, supporting surface mount assembly with a maximum power dissipation of 300 mW on FR-4 boards.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- High precision ±2% Zener voltage grading per E24 standard
- Robust electrostatic discharge protection exceeding 8 kV HBM
Applications
- Precision voltage reference circuits requiring low tolerance
- Overvoltage protection for sensitive signal lines
- Voltage clamping in portable electronic devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure compliance with RoHS directives and material categorization requirements relevant to the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with high voltage accuracy is required in a small footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Confirm that the operating temperature range of -55 °C to +150 °C aligns with the system's thermal constraints and that the SOT-23 package dimensions fit the PCB layout.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of Zener voltages from 2.2 V to 75 V in both single and dual configurations. The 'B' designation indicates the tighter ±2% tolerance grade compared to the standard 'C' grade.
