Overview
The Nexperia PZU5.1DB2,115 is a dual isolated general-purpose Zener diode housed in the SOT353 (SC-88A) surface-mounted package. It features a nominal working voltage of 5.1 V with a tolerance of approximately ±2%. The device supports a total power dissipation of up to 250 mW and a non-repetitive peak reverse power dissipation of 40 W. Key electrical characteristics include a differential resistance of 60 Ω at IZ = 5 mA, a maximum reverse current of 2 μA, and a temperature coefficient of 0.3 mV/K. It is qualified according to AEC-Q101 standards.
Feature Summary
- Dual isolated diode configuration within a compact five-lead plastic package
- High precision voltage regulation with approximately ±2% tolerance series
- Automotive-grade qualification compliant with AEC-Q101 standards
- Halogen-free dark-green plastic package suitable for surface-mount design
Applications
- General regulation functions
- Voltage reference circuits
- Over-voltage protection in automotive electronics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and marking codes. Confirm that the component meets the required AEC-Q101 automotive qualification standards for the intended application environment. Cross-reference the datasheet revision history to ensure the latest thermal and electrical specifications are applied during design integration.
Selection Notes
Select this component when space-constrained designs require dual independent Zener regulators in a minimal footprint. The ±2% tolerance makes it suitable for precision applications compared to standard ±5% variants. Ensure the operating junction temperature remains within the specified -55 °C to +150 °C range to maintain performance reliability under varying thermal conditions.
Part Context
This part belongs to the PZUxDB2 series, which offers a wide working voltage range from 2.7 V to 24 V. The series utilizes the SOT353 package to provide a small standard plastic solution for surface-mounted designs. It serves as a compact alternative to through-hole or larger SMD packages for high-density circuit layouts requiring dual regulation capabilities.
Replacement Considerations
Direct substitutes within the same series include other PZUxDB2 types with different voltage ratings but identical pinouts and package dimensions. Verify compatibility by checking the specific Zener voltage requirements and ensuring the replacement maintains the ±2% tolerance and AEC-Q101 qualification if automotive use is required.
