Overview
The DZ23C39_R1_00001 is a dual surface mount Zener diode from the DZ23C series manufactured by Panjit. It features a common cathode configuration within an SOT-23 plastic package. The nominal Zener voltage is 39 V, with a maximum Zener impedance of 90 Ohms at a test current of 5 mA and a maximum reverse leakage current of 100 nA at 29 V. The device supports a power dissipation rating of 300 mW and operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-saving designs.
- Manufactured using lead-free materials compliant with EU RoHS 2.0 standards.
- Utilizes green molding compound adhering to IEC 61249 environmental specifications.
Applications
- Voltage regulation circuits requiring compact dual-channel solutions.
- Clipping and clamping applications in signal processing.
- Reference voltage generation in low-power electronic systems.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging orientation and reel size. Confirm compliance requirements such as RoHS 2.0 and IEC 61249 green compound standards prior to procurement. Ensure that the component lot number is recorded for traceability purposes during quality assurance processes.
Selection Notes
Select this component when a dual Zener solution in a common cathode arrangement is required within an SOT-23 footprint. Evaluate the 300 mW power dissipation limit and thermal resistance characteristics against the expected operating conditions. Consider the 90 Ohm impedance value for circuit stability requirements.
Part Context
This part belongs to the DZ23C2V4 series, which covers nominal Zener voltages ranging from 2.4 V to 51 V. The series provides various voltage options within the same SOT-23 package form factor, allowing designers to standardize on a single package type across different voltage reference needs.
Replacement Considerations
Direct substitutes include other DZ23C series variants with identical pinouts but different voltage ratings, such as DZ23C36 or DZ23C43. Cross-brand replacements must match the SOT-23-3 package, 300 mW power rating, and common cathode configuration.
FAQ
What is the marking code for the DZ23C39?
The marking code for the DZ23C39 variant is V29.
What is the thermal resistance of the junction to ambient air?
The thermal resistance (RΘJA) is 420 °C/W when mounted on 5mm² land areas.
Is a common anode version available in this series?
Yes, a common anode style is available; refer to the AZ Series for those options.
