Product details
Overview
DMP32D9UDA-7B from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in an ultra-small X2-DFN0806-6 package (0.8 mm × 0.6 mm), rated for -30 V VDSS, 5 Ω RDS(ON) @ VGS = -4.5 V, and -0.22 A continuous drain current at TA = +25°C. It features low gate threshold voltage (-0.4 to -1.0 V), ESD-protected gates, and is optimized for space-constrained power management and analog switching in portable electronics.
For engineers reviewing the DMP32D9UDA-7B datasheet, DMP32D9UDA-7B pinout, DMP32D9UDA-7B application, or DMP32D9UDA-7B equivalent, key selection criteria include its dual-channel P-MOS topology, sub-1V gate drive capability, 345°C/W thermal resistance, and compatibility with low-voltage logic-level control in battery-powered systems.
Technical Context
This dual P-channel MOSFET integrates two independent enhancement-mode transistors sharing a common source configuration in a monolithic die. Each channel supports bidirectional body diode conduction and operates with gate thresholds as low as -0.4 V, enabling direct interface with 1.8 V and 2.5 V microcontroller I/Os without level shifting.
Its ultra-low input capacitance (Ciss = 21.8 pF) and fast switching times (tD(ON) = 3.5 ns, tF = 8.7 ns) minimize dynamic losses in high-frequency load-switching applications, while the 0.36 W power dissipation rating is validated on minimum-pad-layout PCBs per JESD51-7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum drain-source blocking voltage before avalanche breakdown |
| RDS(ON) @ VGS = -4.5 V | 5 Ω max - Ensures <110 mW conduction loss at -100 mA load current |
| ID Continuous | -0.22 A @ TA = +25°C - Validated under JEDEC-standard thermal test board conditions |
| VGS(TH) | -0.4 to -1.0 V - Enables reliable turn-on with 1.8 V logic outputs |
| Ciss | 21.8 pF - Limits gate drive energy and reduces switching transition time |
| RθJA | 345 °C/W - Defines thermal derating slope for ambient-limited operation on minimal copper |
| Package | X2-DFN0806-6 - 0.8 mm × 0.6 mm footprint with 0.3 mm profile, suitable for 0201-class board space |
Pinout & Package
Package: X2-DFN0806-6 - ultra-compact 6-pin dual-flat no-lead package with exposed thermal pad (non-electrical), matte tin-plated copper leadframe, and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side switch node; connects to load supply rail in high-side load switch configuration |
| G1 | Gate of Channel 1 | Logic-controlled input; requires negative bias relative to S1 for turn-on |
| S1 | Source of Channel 1 | Common reference node for Channel 1; tied to system ground or higher potential depending on topology |
| S2 | Source of Channel 2 | Shared source terminal with S1 in standard dual-P layout; enables synchronous or independent switching |
| G2 | Gate of Channel 2 | Independent control input; electrically isolated from G1 for dual-load management |
| D2 | Drain of Channel 2 | Second load-switch node; supports redundant or parallel power path implementation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low gate threshold | VGS(TH) down to -0.4 V enables direct drive from 1.8 V GPIOs without external level shifters |
| Low RDS(ON) at low VGS | 6 Ω @ VGS = -2.5 V ensures usable on-resistance even with weak pull-down drivers |
| ESD-protected gate structure | HBM rating ≥2 kV (per datasheet note) protects against handling-induced gate oxide damage |
| Minimal input capacitance | Ciss = 21.8 pF reduces gate charge demand and speeds up edge transitions |
| Green, halogen-free construction | <900 ppm Br/Cl and <1000 ppm Sb satisfies strict environmental compliance for consumer and medical devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single P-MOS, 30 V, 2.6 Ω @ -4.5 V, SO-8 package (5 mm × 6 mm) | Requires two devices for dual-channel function; larger footprint and higher RθJA (120°C/W) | Select when board space allows SO-8 and higher current (>0.5 A) per channel is needed |
| AP2310W-7 | Dual P-MOS, 20 V, 12 Ω @ -4.5 V, same X2-DFN0806-6 package | Lower voltage rating limits use to ≤12 V systems; higher RDS(ON) increases conduction loss | Select only for cost-sensitive 3.3 V logic systems where -30 V rating is unnecessary |
Compared with DMN3026LSD-13 and AP2310W-7, DMP32D9UDA-7B uniquely balances ultra-compact size, -30 V robustness, and sub-1V gate drive-making it optimal for space- and voltage-critical battery-powered designs where single-device dual-channel integration matters.

FAQ
What is the maximum safe operating junction temperature for DMP32D9UDA-7B?
The absolute maximum junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. Operation above this limit risks permanent device degradation. Derating begins at +70°C ambient due to its 345°C/W thermal resistance; full-rated current is only sustainable below +25°C ambient on minimum-pad layouts.
Can DMP32D9UDA-7B be used in back-to-back configuration for AC blocking?
Yes-its dual P-channel structure supports back-to-back connection (D1–S2 and D2–S1 tied) to block bidirectional current flow. The matched channel characteristics and integrated ESD protection make it suitable for USB Type-C port protection, though external TVS diodes are still recommended for full IEC 61000-4-2 compliance.
Is the thermal pad on the X2-DFN0806-6 package electrically connected?
No-the exposed thermal pad is non-electrical and intended solely for solder-based thermal conduction to the PCB. It must be connected to a large copper pour or internal ground plane via multiple thermal vias to achieve the published RθJA of 345°C/W; leaving it unconnected degrades thermal performance by >50%.
Does DMP32D9UDA-7B require external gate resistors for EMI suppression?
Not inherently-its low Ciss (21.8 pF) and fast switching (tF = 8.7 ns) reduce ringing risk, but a 10–47 Ω series gate resistor is recommended when driving from high-impedance sources or in noisy environments to dampen oscillation and limit peak gate current during transitions.
