Overview
The AZ23B2V7-G3-08 is a silicon planar Zener diode from the Vishay AZ23-G series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with a nominal Zener voltage of 2.7 V and a tight tolerance of ±2%. The device operates at a test current of 5 mA, dissipating up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 20 μA and a dynamic resistance of 83 Ω at 1 kHz. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Tight ±2% Zener voltage tolerance for precision applications
- ESD protection exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping and protection stages in signal processing paths
- Biasing networks in portable electronic devices
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm tape-and-reel packaging specifications. Ensure that the procurement channel sources components directly from authorized distributors to maintain compliance with RoHS directives and material categorization standards defined by Vishay.
Selection Notes
Select this component when a precise 2.7 V reference is required within a compact SOT-23 footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Designers must account for the 83 Ω dynamic resistance and negative temperature coefficient when calculating thermal stability in high-precision analog environments.
Part Context
This part belongs to the AZ23-G series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes silicon planar technology and offers a wide range of graded voltages from 2.2 V to 75 V. The 'B' designation specifically indicates the tighter ±2% tolerance grade compared to the standard 'C' grade.
