Overview
The AZ23C24-G3-18 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 a nominal Zener voltage of 24 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 50 μA at 18 V and a dynamic resistance of 70 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Silicon planar construction ensuring robust performance
- Green commercial grade material composition
Applications
- Voltage reference circuits requiring dual regulation channels
- Clamping and protection applications in signal processing
- Power supply stabilization modules
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 code suffix matches the specified reel quantity and tape width requirements for automated assembly processes.
Selection Notes
Select this variant when a 24 V Zener voltage with ±5% tolerance is required in a compact SOT-23 footprint. Ensure the application environment supports the specified operating temperature range and power dissipation limits on the target PCB layout.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes. The 'C' designation indicates the ±5% voltage tolerance grading, while the '-18' suffix specifies packaging in 10,000-unit reels on 13-inch tapes. It complements other variants in the series offering different voltage levels and tighter tolerances.
