Overview
The AZ23C33-E3-18 is a dual common-anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 33 V with a ±5% tolerance, tested at a current of 2 mA. The device has a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C. Packaged in a surface-mount SOT-23 (TO-236-3) housing, it provides reverse leakage current of 50 μA maximum at 25 V and dynamic resistance of 80 Ω at the test current.
Feature Summary
- Dual common-anode configuration for space-efficient circuit designs
- Silicon planar construction ensuring stable electrical characteristics
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual regulated rails
- Clamping and protection stages in signal processing paths
- Biasing networks in analog integrated circuits
Procurement Notes
Verify the specific ordering code suffix against project requirements. The '-E3' designation confirms RoHS compliance for commercial grade applications. Confirm that the '-18' suffix aligns with the required tape and reel packaging specifications for automated assembly processes.
Selection Notes
Select this component when a dual Zener array with a 33 V nominal rating is required. Ensure the application current does not exceed the 2 mA test condition limits to maintain accuracy. Verify thermal management capabilities if operating near the upper junction temperature limit of 150 °C.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers various voltage grades according to the E24 standard. The 'C' in the part number indicates the standard ±5% voltage tolerance available in the commercial grade product line.
