Overview
The AZ23B7V5-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 package. It features a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 5 V and a dynamic resistance of 7 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
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- Lead-free construction compliant with RoHS standards
Applications
- Voltage reference circuits requiring precise dual rails
- ESD protection for sensitive signal lines
- Clamping applications in low-power consumer electronics
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm tape-and-reel specifications and quantity per reel. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Confirm compliance requirements such as RoHS status prior to finalizing orders.
Selection Notes
Select this part when a dual Zener array with high voltage accuracy is required in a compact surface-mount footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Consider the thermal resistance and power dissipation limits relative to the ambient operating conditions and PCB copper area available for heat spreading.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in a standardized SOT-23 package. The 'B' designation indicates the tighter 2% tolerance grade compared to the 'C' grade.
