Overview
The AZ23B30-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 features a nominal Zener voltage of 30 V with a tight tolerance of ±2%. The device operates at a test current of 2 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 50 μA at 22.5 V and a dynamic resistance of 80 Ω at 2 mA. It 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
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- Green commercial grade construction compliant with RoHS directives
Applications
- Voltage reference circuits requiring precise dual rails
- Transient voltage suppression in signal conditioning paths
- Over-voltage protection for sensitive input stages
- Clamping applications in communication interfaces
Procurement Notes
Verify the specific ordering suffix against official distributor catalogs to confirm reel size and packaging format. Ensure that the component meets the required environmental standards for the intended deployment environment. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing procurement specifications.
Selection Notes
Select this variant when a ±2% tolerance is mandatory, distinguishing it from the standard ±5% 'C' series. Confirm that the 300 mW power dissipation rating on FR-4 substrates aligns with the thermal management strategy. Verify compatibility with automated pick-and-place equipment due to the SOT-23 footprint dimensions.
Part Context
This component belongs to the AZ23-G 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 a compact SOT-23 package. The 'B' designation specifically indicates the tighter ±2% voltage tolerance compared to the standard 'C' grade.

FAQ
What is the difference between the AZ23B30 and AZ23C30 variants?
The primary difference is the Zener voltage tolerance. The AZ23B30 has a ±2% tolerance, while the AZ23C30 has a standard ±5% tolerance.
Is the AZ23B30-G3-18 AEC-Q101 qualified?
Standard parts are not automatically AEC-Q101 qualified; qualification is available upon request directly from the manufacturer.
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
