NX5020UNBKSX

Single Diodes Overview

The NX5020UNBKSX is a dual N-channel enhancement mode Field-Effect Transistor manufactured by Nexperia. It utilizes Trench MOSFET technology within an SOT363 (SC-88) surface-mount package. Key electrical parameters include a drain-source breakdown voltage of 50 V and a continuous drain current of 480 mA. The device features a maximum on-resistance of 6 Ohms at 10 V gate drive. Gate-source voltage limits are ±20 V, with a typical threshold voltage of 950 mV. Total gate charge is specified at 600 pC. Power dissipation reaches 860 mW, operating between -55 °C and +150 °C junction temperature.

Single Diodes Procurement Notes

Verify the specific suffix 'SX' against official Nexperia documentation to confirm reel specifications and tape-and-reel dimensions. Ensure the ordering part number matches the required packaging format for automated assembly lines. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when space constraints require a dual N-channel solution in an SOT363 footprint. The 50 V rating and 480 mA current capability suit low-power switching tasks. Consider the 6 Ohm on-resistance for efficiency requirements in low-voltage logic interfaces. Verify thermal management needs against the 860 mW power dissipation limit in the target enclosure.

Single Diodes Part Context

This device belongs to Nexperia's portfolio of small-signal MOSFETs designed for portable electronics. The SOT363 package allows for high-density PCB layouts. As a dual configuration, it replaces two discrete single transistors, reducing board space and simplifying schematic design for complementary or parallel switching functions.

Single Diodes Replacement Considerations

Check for direct pin-compatible alternatives within the same Nexperia family that share the SOT363 outline and identical electrical ratings. Verify that any substitute maintains the same Trench technology characteristics and ESD protection levels to ensure circuit reliability without redesign.
