NX5020UNBKWX

Single Diodes Overview

The NX5020UNBKWX is a dual N-channel enhancement mode Field-Effect Transistor manufactured by Nexperia. It utilizes Trench MOSFET technology to achieve logic-level compatibility and very fast switching speeds within a compact SOT363 (SC-88) surface-mount plastic package. The device is qualified under the AEC-Q101 standard for automotive applications. Key electrical parameters include a drain-source breakdown voltage of 50 V, a continuous drain current of 480 mA, and a maximum on-resistance of 6 Ohms. It operates with a gate-source voltage range of -20 V to +20 V and supports junction temperatures up to 150 C.

Single Diodes Procurement Notes

Verify the specific suffix 'BX' or 'SX' against the official Nexperia datasheet to confirm the exact tape and reel packaging format required for your assembly line. Ensure the component version matches the intended automotive or industrial reliability requirements. Cross-reference the ordering part number with the manufacturer's latest release notes to confirm availability status and any potential lifecycle changes before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a dual N-channel solution is required in a minimal footprint. The low on-resistance and fast switching make it suitable for high-frequency applications. Verify that the 50 V drain-source voltage rating exceeds the maximum circuit voltage. Confirm that the 480 mA continuous current capability meets the load requirements. Ensure the logic-level threshold allows for proper drive from the available control voltage source.

Single Diodes Part Context

This part belongs to Nexperia's portfolio of small-signal MOSFETs designed for space-constrained designs. The NX5020 series specifically targets applications requiring multiple switching elements in a single package to reduce board area. The use of Trench technology distinguishes it from older planar devices by offering improved switching performance and lower conduction losses in a similar physical form factor.

Single Diodes Replacement Considerations

Direct substitutes must match the SOT363 package, dual N-channel configuration, and 50 V/480 mA ratings. Verify pinout compatibility to prevent circuit damage during replacement. Check if alternative manufacturers offer equivalent AEC-Q101 qualified parts if automotive reliability is mandatory.
