Overview
The DZ23C27-AU is a dual surface mount Zener diode manufactured by Panjit International Inc. in an SOT-23 plastic package. It features a common cathode configuration with two independent Zener elements sharing a single cathode terminal. The device provides a nominal Zener voltage of 27V, operating within a range of 25.65V to 28.35V. It supports a maximum power dissipation of 300mW and maintains a thermal resistance of 420°C/W. Electrical characteristics include a maximum Zener impedance of 80Ω at 5mA and a reverse leakage current of 0.1μA at 20V. The component operates across a junction temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design
- Qualified for automotive applications under the AEC-Q101 standard
- Manufactured using lead-free materials compliant with EU RoHS directives and halogen-free green molding compounds
Applications
- Voltage regulation in automotive electronic systems
- Surge protection circuits requiring dual-channel clamping
- General-purpose voltage reference applications in industrial equipment
Procurement Notes
Verify the specific ordering suffix to confirm packaging orientation and quantity. The suffix indicates whether the product uses tape and reel or tape and ammunition box formats. Confirm the version code corresponds to the required environmental compliance standards before procurement. Ensure the lot number is recorded for traceability purposes during quality assurance processes.
Selection Notes
Select this component when a dual Zener solution with a shared cathode is required in a compact SOT-23 footprint. Verify that the 27V nominal voltage aligns with the target circuit requirements. Consider the 300mW power dissipation limit and ensure adequate thermal management on the PCB land areas. Confirm compatibility with automated insertion processes if high-volume manufacturing is planned.
Part Context
The DZ23C27-AU belongs to Panjit's Dual Surface Mount Zener Diodes series. This family offers various voltage options within the same SOT-23 package to facilitate standardized inventory management. The common cathode style allows designers to utilize two distinct voltage references or protection channels from a single component location, reducing board space compared to discrete single Zener implementations.
Replacement Considerations
Consult the manufacturer datasheet for the available Common Anode style alternatives within the AZ Series. Verify pinout compatibility and electrical parameters before substituting with other manufacturers' dual Zener devices in the SOT-23 package.
