Product details
Overview
DMP32D9UDAQ-7B from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in an X2-DFN0806-6 package, rated for -30V VDSS, 5Ω RDS(ON) @ VGS = -4.5V, and -0.22A continuous drain current at +25°C - designed for ultra-compact, low-voltage power switching in space-constrained automotive and portable electronics.
For engineers reviewing the DMP32D9UDAQ-7B datasheet, DMP32D9UDAQ-7B pinout, DMP32D9UDAQ-7B application, or DMP32D9UDAQ-7B equivalent, key selection criteria include gate threshold voltage (-0.4 to -1.0V), ultra-low input capacitance (21.8 pF), AEC-Q101 qualification, and dual-channel integration in a 0.8 mm × 0.6 mm footprint.
Technical Context
This dual P-MOSFET integrates two matched enhancement-mode channels with ESD-protected gates and body diodes, enabling bidirectional load switching or complementary control in low-power DC-DC bias rails. Its low VGS(TH) allows direct drive from 1.8V/2.5V logic without level shifting.
The device operates across -55°C to +150°C, with thermal resistance RθJA = 345°C/W on minimum pad layout and RDS(ON) stable over temperature - critical for automotive cabin modules and battery-powered sensor nodes where ambient heat and supply headroom are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - supports 24V automotive systems with margin against transients |
| RDS(ON) @ VGS = -4.5V | 5 Ω max - enables <110 mW conduction loss at 150 mA load |
| ID (continuous, +25°C) | -0.22 A - suitable for LED backlight dimming or I/O port protection switches |
| VGS(TH) | -0.4 to -1.0 V - ensures turn-on with 1.8V GPIO, eliminating external driver need |
| Ciss | 21.8 pF - minimizes gate drive energy and switching losses in high-frequency PWM |
| PD | 0.36 W - defines maximum steady-state power in compact 0.8×0.6 mm DFN layout |
| AEC-Q101 Qualified | Yes - validated for automotive applications including infotainment and body control units |

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-channel, 30V, 2.6Ω @ -4.5V, SO-8 package (5×6 mm) | Larger footprint, higher RDS(ON), no AEC-Q101 rating | Use only in non-automotive industrial controls where board space is not constrained |
| AO6401 | Dual P-channel, -30V, 75 mΩ @ -4.5V, TSOP-6 (3×3 mm) | Lower RDS(ON) but larger size, no AEC-Q101, higher gate charge (Qg = 10 nC) | Preferred for high-current (>500 mA) non-automotive applications needing lower conduction loss |

FAQ
What is the maximum junction temperature and thermal resistance of DMP32D9UDAQ-7B?
The device is rated for TJ = -55°C to +150°C. Its thermal resistance from junction to ambient (RθJA) is 345°C/W when mounted on the minimum recommended pad layout per the datasheet. This value assumes a 10μs pulse with 1% duty cycle and is measured on a standard test board - actual performance depends on PCB copper area and airflow.
Does DMP32D9UDAQ-7B support 1.8V logic-level gate drive?
Yes. With a gate threshold voltage range of -0.4 V to -1.0 V and guaranteed turn-on at VGS = -1.5 V (RDS(ON) ≤ 10 Ω), the device fully supports direct drive from 1.8V GPIO outputs. No level shifter is required, simplifying design and reducing BOM count in low-voltage microcontroller systems.
Is the body diode in each channel suitable for reverse-current blocking?
Yes. Each channel includes an integrated body diode with forward voltage VSD = -0.6 to -1.0 V at IS = -10 mA. The diode is rated for continuous forward current up to -0.8 A and supports reverse-biased blocking in high-side switch configurations - confirmed by the -30V VDSS rating and safe operating area curves in the datasheet.
How does the X2-DFN0806-6 package affect solder reflow and reliability?
The X2-DFN0806-6 uses matte tin–annealed copper leads, compliant with MIL-STD-202 Method 208, and has moisture sensitivity level 1 (MSL-1). It requires standard SnPb or lead-free reflow profiles; no special pre-bake is needed. Its 0.36 mm height and symmetric thermal pad design promote uniform solder joint formation and mechanical robustness in vibration-prone automotive environments.
