Product details
Overview
DMC3730UFL3-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single X2-DFN1310-6 (Type B) package, integrating an N-channel (30V, 460mΩ @ 4.5V, 1.1A) and P-channel (–30V, 1000mΩ @ –4.5V, –0.7A) device with ESD-protected gates, low gate threshold voltage, and ultra-small 1.3 mm² footprint - used in compact DC-DC load switches and dual-rail motor drivers.
For engineers reviewing the DMC3730UFL3-7 datasheet, DMC3730UFL3-7 pinout, DMC3730UFL3-7 application, or DMC3730UFL3-7 equivalent, key selection criteria include dual-channel RDS(ON) matching at low VGS, thermal resistance (RθJA = 330°C/W on FR-4), gate charge (QG = 0.9 nC per channel), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual MOSFET implements independent N- and P-channel enhancement-mode transistors sharing no internal connection except substrate isolation; each channel features integrated gate protection diodes and operates with separate gate control. The N-channel delivers 1.1A continuous drain current at VGS = 4.5V with RDS(ON) = 460mΩ, while the P-channel supports –0.7A at VGS = –4.5V with RDS(ON) = 1000mΩ - both rated for ±8V gate-source voltage and –55°C to +150°C junction temperature.
Thermal performance is defined for two mounting conditions: 330°C/W RθJA on standard FR-4 (2 oz Cu, minimal pad), and 156°C/W with 1-inch² copper pour. Dynamic parameters include matched total gate charge (0.9 nC), low reverse transfer capacitance (CRSS ≤ 4.3 pF N-ch / 4.1 pF P-ch), and fast switching (tF = 6.9 ns N-ch / 15.5 ns P-ch).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V (N-ch), –30V (P-ch): Supports dual-rail 3.3V/5V logic-level switching without level shifters |
| RDS(ON) @ VGS = 4.5V | 460mΩ (N-ch), 1000mΩ (P-ch): Enables <1W conduction loss at 1A load in compact space-constrained designs |
| ID Continuous | 1.1A (N-ch), –0.7A (P-ch) at TA = +25°C: Sufficient for LED backlight dimming and small-signal motor control |
| QG | 0.9 nC per channel: Reduces gate drive power and enables high-frequency PWM operation up to 1 MHz |
| RθJA | 330°C/W (standard layout): Requires careful thermal pad design for >150mW sustained dissipation |
| ESD Rating | HBM ≥ 2kV: Integrated gate protection eliminates need for external TVS in low-energy interfaces |
| Qualification | AEC-Q101 qualified: Validated for automotive infotainment and body electronics applications |
Pinout & Package
Package: X2-DFN1310-6 (Type B), ultra-low-profile 1.3 mm × 1.0 mm × 0.35 mm surface-mount package with exposed thermal pad (pin 6), NiPdAu-plated terminals, and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D1) | N-channel drain | Main current path for high-side N-MOSFET; connected to load supply rail |
| 2 (S1) | N-channel source | Return path for N-ch; tied to ground or low-side switch node in H-bridge |
| 3 (G1) | N-channel gate | Logic-level control input; threshold 0.45–0.95V enables direct MCU GPIO drive |
| 4 (D2) | P-channel drain | Main current path for low-side P-MOSFET; connects to load return or ground |
| 5 (S2) | P-channel source | Connected to VCC rail; forms high-side switch when P-ch is used in source-follower configuration |
| 6 (EP) | Exposed thermal pad | Primary heat dissipation path; must be soldered to PCB copper pour for RθJA reduction |
Key Features
| Feature | Design Value |
|---|---|
| Complementary dual-channel integration | Single-package N+P pair eliminates board space and layout mismatch vs discrete solutions |
| Ultra-small footprint (1.3 mm²) | Reduces PCB area by >60% vs SO-8 or SC-70 dual MOSFETs - critical for wearables and TWS earbuds |
| Low VGS(TH) | 0.45–0.95V (N-ch) and –0.5 to –1.1V (P-ch): Ensures full enhancement with 1.8V/2.5V/3.3V I/O domains |
| Fast switching (tF ≤ 15.5 ns) | Minimizes transition losses in 500 kHz–1 MHz DC-DC converters and Class-D audio drivers |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (–40°C to +125°C case) and mechanical shock/vibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary dual-MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVT-7 | Higher RDS(ON) (600mΩ N-ch / 1200mΩ P-ch @ 4.5V), larger 2.0 mm² footprint, same X2-DFN package | Suitable for cost-sensitive industrial controls where thermal margin exceeds requirement | Select when lower gate charge (0.7 nC) and tighter RDS(ON) tolerance are not required |
| SI6926ADQ-T1-GE3 | Different pinout (G1/D1/S1/G2/S2/D2), higher QG (2.1 nC), no AEC-Q101 qualification | Better suited for consumer-grade AC-DC standby supplies than automotive systems | Choose only if AEC-Q101 compliance is unnecessary and board layout allows pinout rework |
Compared with DMC3730UFL3-7, DMC2038LVT-7 trades off on-resistance and size for cost, while SI6926ADQ-T1-GE3 offers higher current capability but lacks automotive qualification and requires PCB redesign due to pinout mismatch.

FAQ
What is the maximum safe operating junction temperature for DMC3730UFL3-7?
The absolute maximum junction temperature is +150°C, validated across the full operating range per AEC-Q101 stress testing. Derating begins at +125°C ambient when mounted on standard FR-4; thermal design must limit power dissipation to maintain TJ ≤ 150°C under worst-case load and ambient conditions.
Can DMC3730UFL3-7 be used in a high-side P-channel switch configuration?
Yes - the P-channel device (Q2) is fully specified for high-side switching with VGS = –4.5V, supporting loads up to 0.7A at 30V. Its –1.1V maximum VGS(TH) ensures reliable turn-on with 3.3V logic-level gate drive when referenced to the source terminal.
Does the exposed pad (Pin 6) require electrical connection?
No - Pin 6 is a thermal pad only, not an electrical terminal. It must be soldered to a PCB copper pour for thermal conduction but must remain electrically isolated from all signals and power planes to avoid short circuits and ensure proper device biasing.
Is DMC3730UFL3-7 compatible with lead-free reflow profiles?
Yes - it is fully RoHS-compliant and qualified for standard JEDEC J-STD-020 Level 1 moisture sensitivity. The package withstands peak reflow temperatures up to 260°C and is compatible with SnAgCu solder paste and standard 240°C peak profiles.
