Overview
The DZ23C16-7 is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two silicon junctions within a single molded plastic case. The nominal Zener voltage is 16 V, with a specified 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 device supports an operating temperature range from -65°C to +150°C. Electrical characteristics include a maximum Zener impedance (ZZT) of 40 Ohms at 1 kHz and a typical temperature coefficient of +0.090 %/°C.
Feature Summary
- Dual Zener diodes integrated in a common cathode configuration for space-efficient circuit design.
- High reliability qualification meeting JEDEC standards for robust performance.
- Environmentally compliant construction that is lead-free, halogen-free, and antimony-free.
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 the specific ordering suffix against manufacturer documentation to confirm commercial versus automotive grade status. Ensure the selected variant matches the required packaging format and quality certifications before finalizing procurement orders.
Selection Notes
Select this component when a matched pair of Zener diodes is required in a minimal footprint. Verify that the 16 V breakdown voltage aligns with the target circuit requirements and that the 300 mW power rating accommodates the expected thermal load.
Part Context
This part belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, offering consistent electrical characteristics and mechanical dimensions across different voltage options.
Replacement Considerations
Compatible substitutes include other dual Zener arrays in SOT-23 packages with matching 16 V ratings and common cathode configurations. Verify pinout compatibility and thermal resistance values before implementation.
FAQ
What is the polarity configuration of the DZ23C16-7?
The device utilizes a common cathode configuration, where the cathodes of both internal Zener diodes are connected to a single terminal.
How does the Zener voltage vary with temperature?
The DZ23C16-7 has a positive temperature coefficient of approximately +0.090 %/°C, meaning the breakdown voltage increases as temperature rises.
Is the DZ23C16-7 suitable for automated assembly?
Yes, the datasheet explicitly states that the device is ideally suited for automated insertion due to its standardized SOT-23 packaging.
