DMP1046UFDB-13

Overview

The DMP1046UFDB-13 is a dual P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a U-DFN2020-6 (Type B) surface-mount package with a maximum height of 0.6mm. The device supports a drain-source voltage (BVDSS) of -12V and offers a maximum continuous drain current (ID) of -3.8A at +25°C. Static drain-source on-resistance (RDS(ON)) is specified as 61mΩ max at VGS = -4.5V, 81mΩ max at VGS = -2.5V, and 115mΩ max at VGS = -1.8V. Total gate charge (Qg) reaches 17.9nC max at VGS = -8V. Operating temperature range spans from -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the required tape and reel packaging quantity of 10,000 units. Confirm that the U-DFN2020-6 (Type B) case material and terminal finish meet the mechanical requirements of the target PCB assembly process. Ensure compliance with J-STD-020 moisture sensitivity level 1 handling protocols during storage and manufacturing.

Selection Notes

Select this component when a compact dual P-channel solution is required for low-voltage power switching. The device provides optimized on-resistance across multiple gate drive voltages (-4.5V, -2.5V, -1.8V), allowing flexibility in logic-level control interfaces. The small footprint and low thermal resistance support dense board layouts in portable electronics where space constraints are critical.

Part Context

This part belongs to the DMP1046 series of dual P-channel MOSFETs from Diodes Incorporated. It utilizes the U-DFN2020-6 package type, which is distinct from larger packages like SOT-23 or SOIC. The 'DMP' prefix indicates a dual P-channel configuration, while 'UFDB' specifies the specific electrical characteristics and package variant within the product line.

Replacement Considerations

The datasheet lists DMP1046UFDB-7 as an alternative version of the same device, differing only in the tape and reel packaging quantity (3,000 units instead of 10,000). No other cross-references or substitute part numbers are provided in the official documentation.
