Diodes Incorporated DMP31D7LV-13

Overview

DMP31D7LV-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT563 package, rated for -30V V_DSS, 0.9Ω R_DS(ON) at V_GS = -10V, and -0.62A continuous drain current at T_A = +25°C. It delivers low on-resistance with fast switching and ESD-protected gate, targeting compact DC-DC converters and motor control circuits.

For engineers reviewing the DMP31D7LV-13 datasheet, DMP31D7LV-13 pinout, DMP31D7LV-13 application, or DMP31D7LV-13 equivalent, key selection factors include its dual-channel P-MOS topology, thermal resistance of 153°C/W (with copper plate), gate threshold of -2.0V typical, and compatibility with 4.5V logic-level drive in space-constrained power stages.

Technical Context

This dual P-channel MOSFET integrates two matched enhancement-mode transistors in a single 6-pin SOT563 package, sharing no internal connection between channels-each has independent source, drain, and gate terminals. Its design emphasizes low R_DS(ON) at low gate drive (1.7Ω @ V_GS = -4.5V) and low input capacitance (C_iss = 19pF), enabling efficient synchronous rectification and load-switching.

The device features an integrated gate protection diode per channel, ±20V V_GSS rating, and guaranteed safe operation up to 150°C junction temperature. Its transient thermal resistance curve supports pulsed operation up to 2.4A (10µs, 1% duty), with SOA limited by R_DS(ON) at low V_DS and package dissipation at higher voltages.

FAQ

What is the maximum continuous drain current for each channel at +70°C ambient?

Each channel supports -0.5A continuous drain current at T_A = +70°C with recommended PCB layout (2oz copper, 1-inch square pad). This is derated from -0.62A at +25°C due to thermal resistance limitations, and assumes no mutual heating between channels in the SOT563 package.

Can DMP31D7LV-13 be used in a synchronous buck converter's high-side position?

No-it is a P-channel device and cannot serve as a high-side switch in standard synchronous buck topologies that require N-channel high-side FETs with bootstrap gate drive. It is appropriate for low-side synchronous rectification or as a high-side switch in buck-derived topologies like reverse buck or load-switch configurations where gate can be pulled below source.

Does the device include body diodes, and what is their forward voltage?

Yes-each channel has an intrinsic body diode with typical V_SD of -0.8V at -0.23A and T_A = +25°C. The diode is rated for -0.38A maximum continuous forward current and supports freewheeling in inductive load applications such as motor drives and DC-DC converters.

Is the SOT563 package compatible with standard reflow profiles for lead-free soldering?

Yes-the SOT563 package uses matte tin annealed over copper leadframe and complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1, allowing use with standard Pb-free reflow profiles (peak 260°C, 20–40s above 217°C) without preconditioning or special handling.
