Overview
The AZ23C16-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration within a single SOT-23 package. The nominal Zener voltage is 16 V with a tolerance range of 15.3 V to 17.1 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 40 Ohms. The device operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a common anode configuration for space-efficient designs.
- High reliability qualification compliant with JEDEC standards and AEC-Q101 ESD ratings.
- Lead-free and fully RoHS compliant construction utilizing halogen and antimony-free green materials.
Applications
- Voltage reference circuits requiring dual regulated rails.
- ESD protection for sensitive signal lines.
- Clamping applications in automated assembly processes.
Procurement Notes
Verify the complete part number includes the suffix '-7-F' to confirm commercial grade qualification and tape & reel packaging containing 3,000 units. Ensure compatibility with standard SMT reflow profiles and verify that the application environment remains within the specified operating temperature limits.
Selection Notes
Select this component when a dual Zener solution sharing a common ground or supply rail is required. The common anode topology simplifies circuit layout compared to discrete components. Confirm that the 16 V breakdown voltage aligns with the target regulation requirements and that the 300 mW power rating accommodates the expected thermal load.
Part Context
This device belongs to the AZ23C series, which covers a wide range of Zener voltages from 2.7 V to 51 V. All variants share identical mechanical dimensions and pinout configurations, allowing for design flexibility across different voltage requirements without altering the PCB footprint.
Replacement Considerations
The AZ23C16Q-7-F serves as the automotive qualified alternative within the same family. Other manufacturers may offer functionally equivalent dual Zener arrays in SOT-23 packages, but electrical parameters such as impedance and leakage current should be verified against the official datasheet specifications.
