Overview
The PZU12DB2,115 is a dual Zener diode array manufactured by Nexperia USA Inc., designed for surface-mount applications. It features two independent Zener diodes housed in a compact SOT-363 (SC-88) package. The nominal Zener voltage is 12 V with a tolerance of ±2%. Each diode supports a maximum power dissipation of 250 mW at ambient temperature. The device operates within a junction temperature range of -55°C to +150°C and is qualified under the AEC-Q101 standard for automotive reliability. Reverse leakage current is specified at 5 µA when tested at 1 V.
Feature Summary
- Dual independent Zener configuration in a single compact surface-mount package
- High voltage regulation accuracy with ±2% tolerance
- Automotive-grade qualification compliant with AEC-Q101 standards
- Extended operating temperature range suitable for harsh environments
Applications
- Voltage reference circuits requiring precise dual rails
- Over-voltage protection for sensitive signal lines
- Clamping applications in automotive electronic control units
Procurement Notes
Verify the specific suffix 'B2' indicates the ±2% tolerance variant during sourcing. Confirm the package designation matches SOT-363 requirements for PCB layout. Ensure supply chain sources provide valid AEC-Q101 certification documentation for automotive integration projects.
Selection Notes
Select this component when space-constrained designs require two isolated voltage references or clamping functions. The ±2% tolerance offers tighter regulation than standard ±5% devices. Verify that the 250 mW per-diode power rating suffices for the expected thermal conditions in the final assembly.
Part Context
This part belongs to Nexperia's PZUXDB series of dual Zener arrays. These components are engineered to replace discrete dual-diode solutions, reducing board area and assembly complexity. The series provides various voltage options and tolerance grades to support diverse analog and digital circuit protection needs.
Replacement Considerations
Direct substitutes include other Nexperia dual Zener arrays in SOT-363 packages with matching 12 V nominal voltage and ±2% tolerance, such as variants from the same PZUXDB family. Cross-brand replacements must match the pinout, package dimensions, and electrical characteristics precisely.
