Overview
The DZ4J270K0R is a dual Zener diode manufactured by Panasonic Industry, designed for surface-mount applications. It features a nominal Zener voltage of 27V with a tolerance of 5% and a maximum power dissipation of 200mW. The device utilizes the SMini4 F3 B package (SC-113BB), measuring 2 x 1.25 x 0.6mm. Key electrical parameters include a maximum reverse leakage current of 100nA, a Zener impedance of 80 Ohms at a test current of 5mA, and a voltage temperature coefficient of 2.5mV/°C. It operates within a temperature range of -40°C to +150°C.
Feature Summary
- Dual configuration providing two independent Zener diodes in a compact footprint.
- High thermal stability with an extended operating temperature range up to 150°C.
- Low leakage current characteristics suitable for precision voltage reference circuits.
Applications
- Voltage regulation in automotive electronic control units.
- Over-voltage protection for signal lines in industrial equipment.
- Reference voltage generation in portable battery-powered devices.
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status via official datasheets before integration. Check for end-of-life notices as discontinuation may affect long-term supply chain stability. Ensure storage conditions adhere to moisture sensitivity levels specified in the manufacturing data sheet.
Selection Notes
Select this component when dual isolated Zener functions are required in space-constrained designs. Compare Zener impedance and leakage current against circuit requirements for noise-sensitive applications. Verify package compatibility with PCB footprints, specifically the SMini4 F3 B dimensions. Consider the voltage temperature coefficient for environments with significant thermal fluctuations.
Part Context
This part belongs to the Panasonic DZ4J series of surface-mount Zener diodes. The series is characterized by small packages offering high power density relative to size. It complements other Panasonic passive components like capacitors and resistors in complete circuit solutions. The DZ4J series targets automotive and industrial sectors requiring reliable voltage clamping.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Panasonic's official replacement guide or contact technical support for qualified alternatives if this specific model is discontinued or unavailable.
