Product details
Overview
DMP31D7LVQ-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT563 package, rated for -30V VDSS, 0.9Ω RDS(on) at VGS = -10V, and -0.62A continuous drain current at +25°C - designed for compact, high-efficiency power management in space-constrained DC-DC converters and motor control circuits.
For engineers reviewing the DMP31D7LVQ-7 datasheet, DMP31D7LVQ-7 pinout, DMP31D7LVQ-7 application, or DMP31D7LVQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (0.36 nC at VGS = -4.5V), dual-channel integration in 1.6 mm × 1.6 mm footprint, and ESD-protected gate enabling robust operation in automotive and industrial environments.
Technical Context
This device integrates two matched P-channel MOSFETs sharing a common source configuration per channel, with independent gate terminals enabling synchronous or complementary switching control. Its -1.0 to -2.6 V gate threshold voltage ensures reliable turn-on with standard logic-level drivers down to -4.5 V.
The MOSFET features low input capacitance (Ciss = 19 pF) and fast switching times (tD(on) = 30 ns, tF = 31 ns), supporting high-frequency operation up to 1 MHz in buck regulators and load switches while minimizing switching losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - maximum blocking voltage for automotive 24 V rail and industrial 28 V systems |
| RDS(on) | 0.9 Ω @ VGS = -10 V - enables <100 mW conduction loss at 330 mA load in compact DC-DC stages |
| ID (continuous) | -0.62 A @ TA = +25°C - supports low-power motor drive and load switch applications with FR-4 PCB layout |
| Qg | 0.36 nC @ VGS = -4.5 V - reduces gate drive power and enables efficient operation with low-current controllers |
| Ciss | 19 pF - minimizes Miller effect and improves noise immunity in high-dV/dt environments |
| TJ range | -55°C to +150°C - qualified for under-hood automotive and industrial ambient conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single-channel, 30 V, 0.055 Ω RDS(on) at -10 V; larger TSOP-6 package (3.05 mm × 1.6 mm) | Requires two devices for dual functionality; higher conduction efficiency but 2.5× larger PCB area | Select when lowest RDS(on) dominates over size and channel integration |
| SI3993DV-T1-GE3 | Dual P-channel, 20 V VDSS, 1.2 Ω RDS(on) at -4.5 V; same SOT563 footprint | Limited to 12 V systems; lower voltage rating restricts use in 24 V automotive subsystems | Select only for cost-sensitive 12 V consumer applications where -30 V margin is unnecessary |
Compared with DMN3026LSD-13 and SI3993DV-T1-GE3, DMP31D7LVQ-7 uniquely balances AEC-Q101 compliance, -30 V rating, dual-channel integration in SOT563, and 0.36 nC gate charge - making it optimal for space-constrained, safety-critical 24 V automotive power nodes.

FAQ
What is the maximum safe operating junction temperature for DMP31D7LVQ-7?
The absolute maximum junction temperature is +150°C, with derating required above +25°C ambient. At TA = +70°C, continuous drain current drops to -0.5 A due to thermal resistance (RθJA = 153°C/W with 1-inch² copper). Operation beyond this limit risks permanent parametric shift or bond-wire failure.
Can DMP31D7LVQ-7 be used in back-to-back configuration for reverse polarity protection?
Yes - its dual P-channel structure supports back-to-back connection (D1–S2 and D2–S1 tied) to block reverse current in USB-C and 24 V automotive inputs. The integrated body diodes provide inherent 0.8 V forward drop, eliminating need for external Schottkys while maintaining <1.2 V total conduction loss at 200 mA.
Is the SOT563 package lead-free and RoHS compliant?
Yes - DMP31D7LVQ-7 uses matte tin annealed over copper leadframe, fully compliant with EU RoHS Directive 2015/863/EU (RoHS 3), with no intentionally added lead, halogens, or antimony. Moisture sensitivity level is rated at Level 1 per J-STD-020, allowing unlimited floor life before reflow.
How does the gate threshold voltage affect drive compatibility with 3.3 V microcontrollers?
VGS(th) ranges from -1.0 V to -2.6 V, meaning full enhancement requires VGS ≤ -2.6 V. A 3.3 V MCU GPIO cannot directly drive it - a level shifter or dedicated gate driver (e.g., TC4427) is required to generate -4.5 V or -10 V gate swing for RDS(on) ≤ 1.7 Ω operation.
