UMH25NTN

Overview

The UMH25NTN is a dual N-channel MOSFET array manufactured by Rohm Semiconductor, housed in an SOT-323 (SC-70) surface-mount package. This component integrates two independent N-channel enhancement mode field-effect transistors within a single compact footprint, designed for low-voltage switching applications. Key electrical characteristics include a drain-source voltage rating of 25V and a continuous drain current capability suitable for portable electronics. The device features low on-resistance to minimize power loss during conduction and optimized gate charge parameters for efficient switching performance in space-constrained circuit designs.

Feature Summary

• Dual N-channel configuration providing two independent switching paths in a minimal footprint
• Optimized for low-voltage operation with enhanced thermal stability
• Designed for high-speed switching applications requiring low input capacitance

Applications

• Battery protection circuits in mobile devices
• Load switching for portable consumer electronics
• DC-DC converter output stages

Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications against the official Rohm Semiconductor datasheet before procurement. Ensure that the requested part number matches the exact pinout and electrical ratings required for the target application. Confirm compliance with RoHS directives and check for any recent lifecycle status updates or obsolescence notices directly from authorized distributors or the manufacturer's official channels.

Selection Notes

Select this component when a dual N-channel solution is required in an SOT-323 package for space-constrained designs. Evaluate the maximum operating temperature range and ensure the thermal resistance characteristics meet the system's heat dissipation requirements. Compare the gate threshold voltage and on-resistance values against alternative packages to confirm suitability for the specific voltage levels and current loads present in the circuit design.

Part Context

This component belongs to Rohm's lineup of small-signal MOSFETs intended for portable electronic devices. It serves as a compact alternative to discrete single-transistor solutions, reducing board space and assembly complexity. The dual configuration allows for synchronized switching operations or independent control of multiple loads within tight spatial limitations common in modern handheld and wearable technology.

Replacement Considerations

Consult official substitution guides for equivalent dual N-channel MOSFETs in SOT-323 packages. Verify that potential replacements match the 25V drain-source voltage rating and similar on-resistance specifications. Ensure pin compatibility and thermal performance are comparable to maintain circuit integrity without redesigning the PCB layout.
