Overview
The Panasonic DZ4J390K0R is a dual silicon epitaxial planar Zener diode configured as two parallel single units within an SMini4-F3-B package. It provides a nominal Zener voltage of 37.2V with a tolerance range of 37.05V to 40.95V at a test current of 2mA. The device supports a total power dissipation of 200mW and operates within an ambient temperature range of -40°C to +85°C, with a junction temperature limit of 150°C. Key electrical parameters include a maximum reverse leakage current of 0.05µA at 30V, a Zener impedance of 300Ω, and a temperature coefficient of 37.2mV/°C.
Feature Summary
- Dual configuration providing two independent Zener channels in a compact surface-mount footprint.
- Low Zener operating resistance for stable voltage regulation performance.
- Excellent rising characteristics of Zener current for effective surge absorption applications.
Applications
- Constant voltage reference circuits
- Surge absorption circuits
- General office equipment and household appliances
Procurement Notes
Verify the specific ordering suffix K0R against official Panasonic documentation to confirm packaging details and compliance status. Ensure that the selected component meets the required environmental standards for the intended application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel Zener solution is required in a minimal footprint. Consider the 37.2V nominal voltage and 200mW total power dissipation limits during circuit design. Verify thermal management requirements based on the specified derating curve for ambient temperatures exceeding 85°C.
Part Context
This part belongs to the Panasonic DZ4 series of surface mount Zener diodes. It utilizes the SMini4-F3-B package, which is equivalent to the JEITA SC-113BB standard. The series is designed for general-purpose constant voltage and surge protection tasks in consumer electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Panasonic documentation or authorized distributors for cross-reference information if replacement is necessary.
