Product details
Overview
DMP32D5LFA-7B from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for low-voltage load switching in space-constrained portable electronics. It features -30V V(BR)DSS, 1.5 Ω RDS(on) at VGS = -4.5V, -0.3A continuous drain current, and an ultra-low-profile X2-DFN0806-3 package (0.4mm height), enabling use in thin battery-powered devices such as wearables and IoT sensors.
For engineers reviewing the DMP32D5LFA-7B datasheet, DMP32D5LFA-7B pinout, DMP32D5LFA-7B application, or DMP32D5LFA-7B equivalent, key selection criteria include gate-threshold voltage (-0.4V to -1.2V), ESD protection, ultra-small footprint (0.48mm²), low RDS(on) at 2.5V drive, and thermal resistance (353°C/W) on FR-4 PCB.
Technical Context
This MOSFET operates as a single-polarity high-side load switch with integrated gate protection diode and ESD-hardened structure. Its low VGS(th) enables direct battery-level control (e.g., from 2.5–3.6V Li-ion cells), while its 0.4mm profile supports stacked PCB architectures in ultra-thin form factors.
The device uses a silicon die in a thermally enhanced, lead-free X2-DFN0806-3 package with NiPdAu-plated terminals. Junction-to-ambient thermal resistance is 353°C/W under standard FR-4 mounting, and safe operating area (SOA) is defined up to 10s DC pulse at TJ ≤ 150°C with VDS = -15V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -30V - maximum blocking voltage before avalanche conduction begins |
| RDS(on) | 1.5 Ω @ VGS = -4.5V - ensures <150mW conduction loss at 0.3A load current |
| ID (continuous) | -0.3 A @ TA = +25°C - usable for low-power peripheral enable/disable functions |
| VGS(th) | -0.4 to -1.2 V - allows reliable turn-on from single-cell lithium batteries without level shifting |
| Qg | 0.7 nC - enables fast switching with minimal gate-drive power in duty-cycled applications |
| RθJA | 353 °C/W - defines thermal derating on minimal-pad FR-4 layout; limits power dissipation to 360mW at ambient |
| Ciss | 40.9 pF - impacts gate-drive loop stability and switching speed in high-frequency PWM control |
Pinout & Package
Package: X2-DFN0806-3 - 0.4mm height, 0.48mm² footprint, 3-terminal bottom-exposed thermal pad (no internal thermal slug connection), RoHS-compliant NiPdAu finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel conduction | Connected to system ground or common rail; ties to internal body diode cathode |

| 3 (Gate) | Control electrode for channel modulation | Driven by microcontroller GPIO; protected by integrated gate diode and ESD structures |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.4mm height enables stacking in <1.0mm total Z-height assemblies (e.g., smart badges) |
| Direct battery drive | VGS(th) down to -0.4V supports activation from 2.5V–3.6V Li-ion/Li-Po without gate driver IC |
| ESD protection | HBM ≥ 2kV per JESD22-A114 - eliminates need for external TVS in handheld ESD environments |
| Green packaging | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); UL 94V-0 mold compound |
Applications
| Wearable Power Management | USB-C Port Power Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LFG-7 | RDS(on) = 2.2 Ω @ VGS = -4.5V; larger X1-DFN1006-3 package (0.55mm height) | Higher conduction loss limits use to sub-0.2A loads; less suitable for <0.8mm Z-height designs | Prefer where higher surge current (IDM = -2.5A) is required over footprint minimization |
| AO3401 | RDS(on) = 0.085 Ω @ VGS = -4.5V; SOT-23 package (1.45mm height, 2.9mm² footprint) | Lower RDS(on) reduces heat but increases board area by 16× and height by >3.5× | Choose when thermal budget dominates over mechanical constraints and cost is secondary |
Compared with DMN3026LFG-7 and AO3401, DMP32D5LFA-7B uniquely balances ultra-thin packaging (0.4mm), battery-direct drive capability (VGS(th) ≤ -0.4V), and sufficient RDS(on) for sub-0.3A loads-making it optimal for next-gen compact, battery-sensitive systems where volume and Z-height are non-negotiable.

FAQ
What is the maximum continuous drain current for DMP32D5LFA-7B at 70°C ambient?
The maximum continuous drain current is -0.2 A at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations on the X2-DFN0806-3 package with standard FR-4 mounting and minimum recommended pad layout.
Does DMP32D5LFA-7B include intrinsic ESD protection, and what level is rated?
Yes, DMP32D5LFA-7B integrates on-die ESD protection rated to ≥2 kV HBM (Human Body Model) per JESD22-A114. No external ESD components are required for typical handheld or portable equipment environments.
Can DMP32D5LFA-7B be used with a 2.5V GPIO for gate drive?
Yes - its gate-threshold voltage range of -0.4 V to -1.2 V ensures full enhancement with 2.5V logic-high signals (VGS = -2.5V), delivering RDS(on) ≤ 2.5 Ω and supporting -0.2 A continuous current at that drive level.
Is the thermal pad on the X2-DFN0806-3 package electrically connected to any terminal?
No - the bottom thermal pad in the X2-DFN0806-3 package is electrically isolated and serves only for thermal conduction to the PCB. It must be soldered to a copper pour for thermal performance but must not be shorted to Source, Drain, or Gate.
