Overview
The DZ23C3V0-7-F 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 a nominal Zener voltage of 3.0 V and a tolerance range of 2.8 V to 3.2 V at a test current of 5.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. Electrical specifications include a maximum Zener impedance (ZZT) of 95 Ω at 1 kHz and a typical negative temperature coefficient of -0.060 %/°C.
Feature Summary
- Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design.
- Compact SOT-23 surface-mount package optimized for automated insertion processes.
- Low voltage matching between the two internal diodes, ensuring a differential variation of less than 5%.
Applications
- Voltage reference circuits requiring precise low-voltage regulation.
- Clamping applications for protecting sensitive input lines from transient overvoltages.
- Biasing networks in analog signal processing stages.
Procurement Notes
Verify that the ordering suffix matches the required commercial grade specification. Confirm the packaging format corresponds to tape and reel quantities as defined in the manufacturer's documentation. Ensure compliance with RoHS directives and lead-free plating requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution is needed in a minimal footprint. Verify that the 300 mW power rating accommodates the expected thermal load. Check that the negative temperature coefficient aligns with the stability requirements of the target application environment.
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, all sharing the same SOT-23 mechanical outline and common cathode topology.
Replacement Considerations
Compatible substitutes include other dual Zener arrays in SOT-23 packages with similar voltage ratings and power dissipation limits. Verify pinout compatibility and electrical parameters such as impedance and leakage current before substitution.
