Overview
The AZ23B15-G3-08 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 sharing a common anode terminal. The nominal Zener voltage is 15 V with a tight tolerance of ±2%. Electrical testing is conducted at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Tight voltage tolerance of ±2% for precision regulation applications
- AEC-Q101 qualified for automotive reliability standards
- High electrostatic discharge protection capability
Applications
- Voltage reference circuits requiring dual rails
- Overvoltage protection for sensitive electronic components
- Clamping circuits in automotive electronics
- Signal conditioning and level shifting
Procurement Notes
Verify compliance with RoHS directives and material categorization requirements before procurement. Confirm that the specific ordering suffix matches the required tape and reel quantity. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to prevent package damage during soldering processes.
Selection Notes
Select this component when a dual Zener array with high voltage accuracy is required in a compact footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Verify that the 300 mW power dissipation rating aligns with the thermal management capabilities of the target PCB layout under expected operating temperatures.
