DZ4J110K0R

Overview

The Panasonic DZ4J110K0R is a dual silicon epitaxial planar Zener diode in an SMini4-F3-B package. It provides two isolated Zener elements with a nominal voltage of 11V at a test current of 5mA and a tolerance of ±5%. The device supports a total power dissipation of 200mW, operating within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum reverse leakage current of 0.1µA at 8V, a typical Zener impedance of 30Ω at 5mA, and a temperature coefficient of 8.3mV/°C. It features high ESD protection rated at ±8kV contact discharge.

Feature Summary

• Dual configuration providing two independent Zener channels within a compact surface-mount footprint.
• High electrostatic discharge (ESD) immunity rated at ±8kV for robust circuit protection.
• Low Zener operating resistance and excellent rising characteristics for stable voltage regulation.
• Halogen-free and RoHS compliant construction suitable for environmentally sensitive applications.

Applications

• Constant voltage reference circuits requiring dual isolated channels.
• Surge absorption and transient voltage suppression in electronic equipment.
• Input/output protection stages in communication devices and measuring instruments.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and marking configurations. Confirm that the component meets all required environmental standards, such as halogen-free status, prior to finalizing procurement orders for production integration.

Selection Notes

Select this component when a dual-channel Zener solution is required in a minimal footprint. Ensure the design accounts for the 200mW total power dissipation limit and the 8.3mV/°C temperature coefficient. Verify that the 11V nominal voltage aligns with the target regulation requirements under the expected operating current conditions.
