Overview
The DZ23C12Q-7-F is an automotive-grade dual Zener diode array manufactured by Diodes Incorporated. It features a common cathode configuration within a compact SOT-23 surface-mount package. The nominal Zener voltage is 12V, with an operating range of 11.4V to 12.7V at a test current of 5.0mA. Maximum power dissipation is rated at 300mW, supported by a thermal resistance of 417°C/W from junction to ambient air. The device operates reliably across a temperature range of -65°C to +150°C and meets AEC-Q101 qualification standards for high-reliability automotive applications.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration
- Qualified to AEC-Q101 standards for automotive reliability
- Lead-free construction fully compliant with RoHS directives
- Halogen and antimony-free green device packaging
Applications
- Automotive voltage regulation circuits
- Signal clamping and protection in vehicle electronics
- Reference voltage generation in high-reliability systems
Procurement Notes
Verify the Q-suffix indicates AEC-Q101 automotive qualification rather than commercial grade. Confirm the specific ordering suffix matches the required tape and reel shipping format. Ensure the component source aligns with IATF 16949 certified manufacturing facilities as specified for automotive parts.
Selection Notes
Select this part when dual independent Zener channels are required in a minimal footprint. The common cathode topology simplifies circuit design compared to discrete components. Verify that the 300mW power rating accommodates the expected thermal load without exceeding the maximum junction temperature limits under worst-case conditions.
Part Context
This component belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The 'Q' designation specifically identifies it as the automotive-grade variant within the broader product family. It shares mechanical dimensions and basic electrical characteristics with commercial counterparts but adheres to stricter automotive quality control requirements.
