Product details

Overview

DMP31D7LDWQ-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT363 package, rated for -30V V_DSS, 0.9Ω R_DS(ON) @ V_GS = -10V, and -0.55A continuous drain current at +25°C - designed for compact, high-efficiency power management in space-constrained automotive and industrial DC-DC converters.

For engineers reviewing the DMP31D7LDWQ-7 datasheet, DMP31D7LDWQ-7 pinout, DMP31D7LDWQ-7 application, or DMP31D7LDWQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, dual-channel gate-protected topology, low R_DS(ON) at -4.5V drive, ESD-hardened gate, and thermal performance under 301°C/W R_θJA with enhanced copper pad layout.

Technical Context

This device integrates two identical P-channel MOSFETs in a single SOT363 package with independent gate, source, and drain terminals per channel. Each channel features a built-in gate protection diode and shares no internal connection between channels - enabling independent control of high-side switching paths or complementary half-bridge configurations.

Its -2.2V typical V_GS(TH) ensures reliable turn-on with standard logic-level (e.g., 3.3V/5V) gate drivers, while low C_iss (19pF) and fast switching times (t_D(ON) = 30ns, t_F = 31ns) support high-frequency operation up to 1MHz in synchronous buck regulators and load-switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - supports rail-to-rail operation in 24V automotive systems with margin against transients.
R_DS(ON) @ V_GS = -10V	0.9Ω max - enables ≤450mW conduction loss at -0.55A, critical for thermally limited PCB layouts.
R_DS(ON) @ V_GS = -4.5V	1.7Ω max - ensures functional switching with 3.3V GPIO or low-voltage microcontroller outputs.
Q_g @ V_GS = -10V	0.8nC - reduces gate drive power and allows use of low-current drivers without slew-rate degradation.
C_iss	19pF - minimizes Miller effect and improves noise immunity in high-dV/dt environments.
T_J Range	-55°C to +150°C - validated for under-hood automotive locations and industrial motor control enclosures.

Pinout & Package

Package: SOT363 - 6-pin, surface-mount, lead-free, green molding compound (UL 94V-0), 0.006g weight, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
G1	Gate of Q1	Independent control input for first P-MOSFET; requires external pull-up for high-side switching.
S1	Source of Q1	High-side reference node for Q1; connects to supply rail in load-switch configuration.
D1	Drain of Q1	Switched output for Q1; ties to load or synchronous rectifier node.
G2	Gate of Q2	Independent control input for second P-MOSFET; electrically isolated from G1.
S2	Source of Q2	High-side reference node for Q2; may be tied to S1 or left separate for dual-rail operation.
D2	Drain of Q2	Switched output for Q2; supports dual-load isolation or parallel current sharing.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and body electronics per stress test requirements (HTOL, TC, HAST).
ESD-protected gate	Withstands ≥2kV HBM per JESD22-A114, eliminating need for external gate Zener clamps.
Low R_DS(ON) at -4.5V	1.7Ω max enables direct interface with 3.3V MCUs without level-shifting circuitry.
Dual-channel isolation	No internal connection between Q1 and Q2 - supports independent load switching or redundant safety paths.

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, 30V, 0.055Ω R_DS(ON) @ -10V, SO-8 package - lower R_DS(ON) but larger footprint and no dual integration.	Requires two devices and additional PCB area for dual-load control; lacks integrated gate protection diodes.	Select when ultra-low conduction loss dominates over board space and gate protection simplicity.
SI3483DV-T1-GE3	Dual P-channel, 30V, 1.2Ω R_DS(ON) @ -4.5V, SOT-363 - same package but higher R_DS(ON) and no AEC-Q101 qualification.	Not suitable for automotive applications; limited to commercial-grade industrial use due to missing PPAP capability.	Select only for cost-sensitive non-automotive designs where thermal margin exceeds 20°C.

Compared with DMN3026LSD-13 and SI3483DV-T1-GE3, DMP31D7LDWQ-7 uniquely delivers AEC-Q101 compliance, gate protection diodes, and dual-channel integration in SOT363 - making it the only option that simultaneously satisfies automotive change control, space constraints, and simplified gate drive design.

FAQ

Is DMP31D7LDWQ-7 suitable for high-side switching in 24V automotive systems?

Yes. With -30V V_DSS, -55°C to +150°C operating range, AEC-Q101 qualification, and ESD-protected gates, it supports 24V nominal systems including load-dump transients. Its -2.2V typical V_GS(TH) ensures reliable turn-on using 3.3V or 5V MCU GPIOs with appropriate pull-up resistors.

What is the maximum safe continuous current per channel at 85°C ambient?

At T_A = +85°C, the derated continuous drain current is -0.32A per channel (based on R_θJA = 301°C/W, P_D = 0.4W, and T_J(max) = 150°C). This assumes FR-4 PCB with 1-inch² copper pour; actual current depends on layout and airflow.

Does DMP31D7LDWQ-7 require external gate resistors for EMI suppression?

Not strictly required, but recommended. While its 729Ω gate resistance limits dI/dt, adding a 10–47Ω series resistor per gate improves EMI performance in noisy automotive environments and prevents ringing during fast switching transitions observed in bench tests.

Can the two channels be paralleled to increase current capacity?

No. The channels are electrically isolated but not matched for current sharing - parameter variation (e.g., ±20% R_DS(ON)) causes uneven current distribution. For higher current, use a single-channel MOSFET with lower R_DS(ON) or implement active current balancing.
