MMFTN620KDW is listed in the FET, MOSFET Arrays range at ChipApex. The manufacturer field lists Diotec Semiconductor. Its product description is MOSFET SOT363 N+N 60V 0.35A 2OHM. Review the specifications below when checking this part for your BOM.
The MMFTN620KDW is a dual N-channel enhancement mode MOSFET in an SOT-363 package. It features a drain-source voltage of 60 V and a continuous drain current of 350 mA. The on-state resistance is less than 2 Ω at VGS = 2.5 V. Power dissipation reaches 410 mW with adequate copper pads. Gate-source voltage withstands ±20 V DC or ±2 kV ESD. Operating temperature spans -55°C to +150°C.
Verify the specific suffix when ordering, as it determines automotive qualification status. Confirm RoHS compliance and REACH registration requirements against project specifications. Ensure the selected packaging matches the intended assembly line equipment capabilities. Validate thermal performance parameters based on actual PCB copper pad dimensions used in the design.
Select this component for applications requiring dual N-channel isolation in minimal space. Evaluate the low threshold voltage against the driving circuit's output levels. Consider the thermal resistance values relative to the available copper area on the printed circuit board. Verify that the peak drain current meets transient load requirements during operation.
This device belongs to Diotec Semiconductor's MMFTN series of small-signal MOSFETs. It utilizes silicon technology optimized for commercial and industrial grade reliability. The SOT-363 footprint allows for dense board layouts compared to single-transistor alternatives.
No official substitutes are listed by the manufacturer. When evaluating alternatives, ensure the replacement supports dual configurations in SOT-363 packages. Verify matching electrical characteristics, specifically the 60 V breakdown voltage and low on-resistance thresholds.
The gate-source voltage can withstand up to ±2 kV under electrostatic discharge conditions.
Power dissipation increases from 320 mW to 410 mW when mounted on a PCB with 625 mm² copper pads per terminal.
Standard versions are commercial/industrial grade. Versions with the -Q or -AQ suffixes are AEC-Q101 compliant or qualified.
