The DMP22D5UFB4-7R is a single P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a drain-source voltage (V_DSS) of -20 V and a continuous drain current (I_D) of -0.4 A at +25°C. The device offers a maximum on-resistance (R_DS(on)) of 1.9 Ω at V_GS = -4.5 V, with higher resistance values at lower gate voltages. It operates within a temperature range of -55°C to +150°C and utilizes an X2-DFN1006-3 package.
Verify the specific ordering suffix '-7R' against official Diodes Incorporated documentation to confirm reel size and packing quantity specifications. Ensure that the X2-DFN1006-3 package dimensions and thermal characteristics align with your printed circuit board layout requirements before finalizing procurement.
Select this component when space constraints are critical due to its ultra-small footprint. Consider the R_DS(on) variations at different gate drive voltages (-1.5V to -4.5V) to ensure compatibility with your system's logic levels. Verify thermal dissipation capabilities based on your specific PCB copper area and via configuration.
This part belongs to the DMP22 series of P-channel MOSFETs from Diodes Incorporated. It is designed to balance low on-resistance with superior switching performance in a miniature surface-mount package suitable for modern portable devices.
