DMP31D7LFB-7B

Overview

The DMP31D7LFB-7B is a P-channel enhancement mode MOSFET from Diodes Incorporated, housed in an X1-DFN1006-3 package. It features a drain-source voltage (V_DSS) of -30V and a continuous drain current (I_D) of -0.81A at +25°C. The device offers low on-state resistance (R_DS(ON)) of 0.9Ω at V_GS = -10V and 1.7Ω at V_GS = -4.5V. Key electrical parameters include a gate threshold voltage (V_GS(TH)) ranging from -1V to -2.6V, total gate charge (Q_g) of 0.36nC at V_GS = -4.5V, and input capacitance (C_iss) of 19pF. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Minimized on-state resistance combined with superior switching performance for high-efficiency power management.
• Significantly reduced footprint compared to traditional SOT23 packages.
• Low gate threshold voltage enabling efficient drive characteristics.
• Integrated ESD protection on the gate terminal.

Applications

• High-efficiency power management applications

Procurement Notes

Verify the specific ordering suffix '-7B' against official Diodes Incorporated documentation to confirm packaging details, specifically the 10,000-unit reel quantity and tape width specifications. Ensure compliance with RoHS 3 and halogen-free requirements as defined by the manufacturer's quality definitions before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a footprint significantly smaller than standard SOT23 packages while maintaining reliable switching capabilities. Consider the -30V rating and -0.81A continuous current limits for appropriate load matching. Evaluate the low gate threshold voltage (-1V to -2.6V) suitability for logic-level driving interfaces in compact power management designs.
