PZU7.5DB2,115

Overview

The Nexperia PZU7.5DB2,115 is a dual isolated general-purpose Zener diode housed in an SOT353 (SC-88A) surface-mounted package. It features a nominal working voltage of 7.5 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 maximum reverse current of 10 μA at IZ = 0.5 mA and a differential resistance of 4 Ω at IZ = 5 mA. It operates within a junction temperature range of -55 °C to +150 °C.

• Dual isolated diode configuration for independent circuit control
• Halogen-free plastic package suitable for surface-mounted design
• Qualified according to AEC-Q101 standards for automotive applications

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and material specifications. Confirm that the component status remains active or qualified for your intended production timeline, as product availability and longevity are subject to change by the manufacturer.

Selection Notes

Select this component when a compact dual Zener solution is required in an SOT353 footprint. Ensure the circuit design accommodates the specified 2% voltage tolerance and thermal constraints. Verify that the operating current aligns with the differential resistance and leakage current specifications provided in the datasheet for optimal performance.

Part Context

This part belongs to the PZUxDB2 series of dual Zener diodes manufactured by Nexperia. The series offers various nominal voltages ranging from 2.7 V to 24 V, all sharing the same SOT353 package and general electrical characteristics. The PZU7.5DB2 variant specifically targets applications requiring a 7.5 V reference or regulation point within a small form factor.

Replacement Considerations

Direct replacements must match the SOT353 package, dual isolated configuration, and 7.5 V nominal voltage. Verify compatibility with AEC-Q101 requirements if used in automotive contexts. Check pinout definitions and thermal resistance values to ensure equivalent performance in the existing PCB layout.
