Overview
The AZ23C33-G3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 33 V with a standard tolerance of ±5%. Electrical testing occurs at a test current of 2 mA, yielding a maximum dynamic resistance of 80 Ω and a reverse leakage current of 50 μA at 25 V. The device supports a maximum power dissipation of 300 mW on FR-4 boards and operates across a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for integrated circuit protection
- Silicon planar construction ensuring high reliability
- Green commercial grade material categorization
Applications
- Voltage reference circuits requiring stable dual-channel regulation
- Input/output protection in portable electronic devices
- Overvoltage clamping in automotive-grade signal lines
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm RoHS compliance status and material categorization details directly from the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when a dual common anode topology is required for shared ground references. Ensure the operating current remains near the specified 2 mA test point to maintain accurate voltage regulation. Verify that the thermal resistance characteristics align with the target PCB footprint design.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes. The 'C' designation indicates a standard ±5% voltage tolerance, while the 'G3' suffix denotes green commercial grade packaging. The '-18' suffix specifies the standard 10,000-unit reel format.
