Overview
The DZ23C16-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 16 V with a tolerance range of ±5%. Maximum power dissipation is 300 mW at +25°C, and the junction-to-ambient thermal resistance is 417 °C/W. Electrical characteristics include a maximum Zener impedance (ZZT) of 40 Ω at IZT = 5.0 mA and a typical temperature coefficient of +0.090 %/°C. Operating and storage temperatures range from -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient designs.
- High reliability qualification meeting JEDEC standards for robust performance.
- Fully RoHS compliant and lead-free construction with halogen and antimony-free green materials.
Applications
- Voltage reference circuits requiring stable dual supply rails.
- Over-voltage protection stages in signal conditioning paths.
- Clamping applications in high-reliability electronic assemblies.
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required commercial grade specifications. Ensure packaging details align with automated insertion requirements. Validate compliance documentation against current regulatory standards before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution in a compact SOT-23 footprint is required. Verify that the 16 V breakdown voltage and ±5% tolerance meet circuit design constraints. Consider the positive temperature coefficient for thermal stability analysis. Evaluate the 300 mW power dissipation limit against expected operating currents to ensure safe junction temperatures.
Part Context
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series covers a wide voltage range from 2.7 V to 51 V. All variants share identical mechanical dimensions and electrical testing conditions, differing primarily in breakdown voltage and associated impedance values.
Replacement Considerations
Cross-reference with AZ23C16-7-F if a common anode configuration is preferred. Verify equivalent packages and electrical parameters for other manufacturers' dual Zener arrays. Ensure thermal resistance and power derating curves match application requirements during substitution.
