Overview
The AZ23C27-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 27 V with a tolerance of ±5 %. Electrical testing is conducted at a test current (IZT1) of 2 mA. Key electrical parameters include a maximum reverse leakage current of 50 μA and a dynamic resistance (ZZ) of 80 Ω at 1 kHz. The device operates within a temperature range of -55 °C to +150 °C and supports a power dissipation of up to 500 mW.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Zener voltages graded according to the international E24 standard
- ESD capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Voltage reference circuits requiring dual stable potentials
- Overvoltage protection for sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm RoHS compliance status and material categorization details directly with authorized distributors or the manufacturer before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required. Ensure the 27 V nominal voltage aligns with the target circuit requirements. Verify that the ±5 % tolerance meets the precision needs of the application and that the SOT-23 package footprint fits the PCB layout constraints.
