Overview
The AZ23B36-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a surface-mount SOT-23 package. It provides two independent Zener elements sharing a common anode terminal. The nominal Zener voltage is 36 V with a tight tolerance of ±2%. Electrical characteristics are measured at a test current of 2 mA, yielding a maximum dynamic resistance of 87 Ω and a reverse leakage current of 50 nA at 27 V. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
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 dual rails
- Transient voltage suppression in signal lines
- Over-voltage protection for sensitive inputs
- Clamping circuits in communication interfaces
Procurement Notes
Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure the procurement channel sources directly from authorized distributors to guarantee compliance with material categorization and environmental standards.
Selection Notes
Select this variant when a precise 36 V breakdown voltage with ±2% accuracy is required in a compact footprint. The dual common anode structure allows for efficient use of board space compared to discrete single diodes. Verify that the operating current aligns with the 2 mA test condition to maintain specified impedance and voltage tolerances.
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 standardized voltages graded according to the E24 standard. The 'B' designation specifically indicates the tighter ±2% tolerance band, distinguishing it from the standard ±5% 'C' grade variants within the same package family.
Replacement Considerations
Direct substitutes include other AZ23B36-G3-08 units from Vishay or equivalent dual common anode Zener arrays with matching 36 V nominal voltage, ±2% tolerance, and SOT-23-3 packaging. Verify thermal resistance and power dissipation ratings match the original design constraints before substitution.
FAQ
What is the marking code for the AZ23B36-G3-08?
