NTLUD3A50PZTAG

Overview

The NTLUD3A50PZTAG is a dual P-channel MOSFET from onsemi's uCool Power series, housed in a compact 6-UDFN (2x2 mm) package with an exposed pad. It features a drain-source voltage rating of -20V and a continuous drain current of -5.6A at 25°C. The device exhibits a maximum on-resistance of 50mΩ at Vgs = -4.5V. Key electrical characteristics include a gate charge of 10.4nC at 4.5V, input capacitance of 920pF at 15V, and a threshold voltage of 1V at 250µA. It supports a junction temperature range of -55°C to +150°C with a power dissipation of 500mW.

Feature Summary

• Dual P-channel configuration integrated into a single compact surface-mount package for space-constrained designs.
• Logic-level gate drive capability allowing direct interfacing with standard logic outputs.
• uCool Power technology optimized for low on-resistance and efficient thermal performance.

Applications

• Low-voltage DC-DC converter synchronous rectification
• Load switching applications in portable electronics
• Power management circuits requiring dual high-side or low-side control

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and REACH declaration requirements for specific regions. Check for potential supply chain disruptions as the manufacturer has announced discontinuation. Ensure storage conditions meet moisture sensitivity level specifications prior to assembly.

Selection Notes

Select this component when a dual P-channel solution is required in a minimal footprint. Verify that the -20V voltage rating and -5.6A current capacity align with system load requirements. Consider the 50mΩ on-resistance impact on conduction losses. Evaluate thermal management needs given the 500mW power dissipation limit in the small UDFN package.

Part Context

This part belongs to onsemi's NTLUD3 family of dual MOSFETs designed for ultra-small form factors. It complements single-channel variants by providing two independent P-channel devices in one package. The series targets mobile and consumer electronics where board space is critical. It utilizes advanced silicon process technology to achieve high performance in a tiny outline no-lead package.

Replacement Considerations

FDMA1023PZ is a documented alternative offering similar -20V dual P-channel specifications. Verify pinout compatibility and thermal characteristics before substitution. Review datasheet differences regarding gate charge and on-resistance to ensure circuit stability.
