Overview
The AZ23C20-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 voltage regulation channels sharing a single anode terminal. The nominal Zener voltage is 20 V with a standard tolerance of ±5%. Electrical testing is conducted at a test current (IZT1) of 5 mA. Key electrical parameters include a maximum reverse leakage current of 0.05 µA and a dynamic resistance (ZZ) of 50 Ω at the specified test current.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Graded Zener voltages conforming to international E24 standards
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual regulated rails
- Overvoltage protection for sensitive input lines
- Clamping applications in signal conditioning paths
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's document number 86339 and revision 1.2 against official Vishay records. Confirm that the ordering suffix -G3-08 corresponds to green commercial grade packaging on an 8 mm tape reel containing 3000 units. Ensure compliance with RoHS directives as indicated in the datasheet specifications.
Selection Notes
Select this specific part when a dual-channel voltage regulator with a shared anode is required within a compact SOT-23 footprint. The ±5% tolerance suits general-purpose applications where tight voltage precision is not critical. Verify that the operating temperature range of -55 °C to +150 °C aligns with the environmental conditions of the target system.
Part Context
This device belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of Zener voltages from 2.2 V to 75 V in both 5% and 2% tolerance grades. The AZ23C20 variant specifically targets the 20 V nominal requirement within this standardized lineup.
