Overview
The Panasonic DZ4J051K0R is a surface-mount Zener diode with a nominal voltage of 5.1V and a maximum power dissipation of 200 mW. It utilizes the SMini4 F3 B package, measuring 2 x 1.25 x 0.6 mm, and features four pins for isolation. The device has a 5% tolerance, a test current of 5 mA, and a maximum reverse leakage current of 100 nA. Its maximum Zener impedance is 60 ohms, with a typical voltage temperature coefficient of 5.8 mV/°C. The component supports a maximum operating temperature of +150 °C.
Feature Summary
- Compact SMini4 F3 B package design for space-constrained applications
- High thermal stability with a maximum operating temperature of +150 °C
- Isolated configuration for precise voltage regulation
Applications
- Voltage reference circuits in compact electronic devices
- Over-voltage protection in low-power systems
- Signal conditioning in consumer electronics
Procurement Notes
Verify the exact manufacturer part number against official Panasonic documentation to ensure compatibility. Confirm package dimensions and pin configurations match your PCB layout requirements. Check for any specific handling or storage instructions provided in the datasheet to maintain component integrity during assembly.
Selection Notes
Select this component when a 5.1V Zener reference is required in a minimal footprint. Ensure the circuit design accommodates the 200 mW power dissipation limit at the expected operating temperature. Verify that the 5% voltage tolerance meets the precision requirements of the target application.
Part Context
This component belongs to the Panasonic DZ4J series of surface-mount Zener diodes. The series is characterized by small packages and high power dissipation capabilities relative to their size. The DZ4J051K0R specifically offers a 5.1V breakdown voltage in the SMini4 F3 B form factor.
Replacement Considerations
Consult official Panasonic substitution guides for verified equivalents. Generic replacements may differ in package dimensions, thermal characteristics, or voltage tolerance. Do not assume cross-compatibility without verifying electrical parameters and physical fit.
