PZU16DB2,115

Overview

The PZU16DB2,115 is a dual isolated general-purpose Zener diode from the PZUxDB2 series, manufactured by Nexperia. It is housed in a SOT353 (SC-88A) very small Surface-Mounted Device plastic package with five leads. The device features two electrically isolated diodes within a single component, offering a nominal working voltage of 16 V with a tolerance series B2 of approximately ±2%. Key electrical parameters include a total power dissipation of 250 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. The junction temperature range extends from -55 °C to +150 °C, and the device is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual isolated diode configuration allowing independent operation within a compact footprint
• Halogen-free dark-green plastic package suitable for surface-mounted design
• AEC-Q101 qualification ensuring suitability for demanding automotive environments
• Wide working voltage range across the series with precise ±2% tolerance options

Applications

• General regulation functions
• Voltage reference circuits requiring isolated channels
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing origin. Ensure compatibility with the SOT353 footprint during PCB layout. Confirm that the selected variant meets the required thermal resistance and power dissipation limits for the intended operating environment before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require two isolated Zener regulators in a single package. The SOT353 package offers a minimal footprint compared to discrete solutions. Consider the ±2% tolerance series if tight voltage accuracy is critical. Verify that the 250 mW total power dissipation rating aligns with the thermal management capabilities of the target application board.

Part Context

The PZU16DB2 belongs to the PZUxDB2 series, which provides dual isolated Zener diodes in the SOT353 package. This series covers nominal voltages from 2.7 V to 24 V, allowing designers to choose specific breakdown voltages while maintaining consistent pinout and package dimensions. The 'B2' designation indicates the specific tolerance class for the Zener voltage.

Replacement Considerations

Direct replacements must match the SOT353 package, dual isolated topology, and 16 V nominal voltage. Verify that any substitute component meets or exceeds the 250 mW total power dissipation and AEC-Q101 qualification requirements to ensure functional equivalence in automotive-grade applications.
