Overview
The DZ4J027K0R is a dual silicon epitaxial planar Zener diode manufactured by Panasonic. It provides a nominal Zener voltage of 2.7 V with a tolerance of ±5% at a test current of 5 mA. The device features a low Zener operating resistance of 110 Ohms and a maximum reverse leakage current of 120 uA at 1 V. Total power dissipation is rated at 200 mW, supporting an operating junction temperature up to 150 °C. It is housed in the SMini4-F3-B (JEITA SC-113BB) surface-mount package, measuring 2.0 mm x 2.1 mm x 0.7 mm.
Feature Summary
- Dual configuration providing two independent Zener diodes within a single compact 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 component authenticity through authorized distribution channels. Confirm that the marking symbol '2J' matches the datasheet specifications. Ensure compliance with EU RoHS directives and UL-94 V-0 flammability ratings prior to integration into final assemblies.
Selection Notes
Select this component when a dual-channel Zener solution is required in a minimal surface-mount area. The 2.7 V breakdown voltage suits low-voltage protection tasks. Verify thermal management requirements against the 200 mW total power dissipation limit under expected ambient conditions.
Part Context
This part belongs to the Panasonic DZ4 series of surface mount Zener diodes. It utilizes the SMini4-F3-B package, which offers significantly smaller dimensions compared to previous generations while maintaining high power dissipation capabilities for its size class.
Replacement Considerations
Direct substitutes include the DZ2J027M0L and DZ4J047K0R from Panasonic, provided electrical parameters align with design requirements. Verify pinout compatibility and package dimensions before substitution.
