Product details
Overview
DMC3025LNS-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single POWERDI®3333-8 (UXB) package, integrating one N-channel (30V, 25mΩ @ 10V) and one P-channel (−30V, 28mΩ @ −10V) device. It delivers 7.2A/−6.8A continuous drain current at 25°C and supports high-efficiency dual-rail power management in compact DC-DC converters and load switches.
For engineers reviewing the DMC3025LNS-7 datasheet, DMC3025LNS-7 pinout, DMC3025LNS-7 application, or DMC3025LNS-7 equivalent, key selection criteria include verified RDS(ON) matching across both channels, thermal resistance (RθJA = 69°C/W with thermal pad), gate charge asymmetry (Qg = 9.8nC / 19.7nC), and complementary threshold voltages (VGS(TH) = +1.0–2.0V / −1.2–−2.4V).
Technical Context
This dual-channel MOSFET uses planar silicon process technology to achieve matched on-resistance and fast switching (tF = 5.8ns / 22ns) while maintaining low input capacitance (Ciss = 500pF / 1188pF). Its complementary topology enables synchronous half-bridge and H-bridge configurations without external level-shifting circuitry.
The device operates across −55°C to +150°C junction temperature, with avalanche-rated energy handling (EAS = 9.8mJ / 24mJ) and body diode recovery (tRR = 5.6ns / 10.4ns). Thermal design leverages the UXB package's low RθJC = 15°C/W and exposed thermal pad for PCB heat spreading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | ±30V - Supports dual-rail 24V systems with 20% headroom for transients |
| RDS(ON) (Q1/Q2) | 25mΩ / 28mΩ @ VGS = ±10V - Enables <1W conduction loss at 7A per channel |
| ID Continuous | 7.2A / −6.8A @ TA = 25°C - Sustains >6A load current in thermally optimized 2oz copper layouts |
| Qg | 9.8nC / 19.7nC @ VGS = ±10V - Determines gate drive power requirement for 1MHz switching |
| Ciss | 500pF / 1188pF @ VDS = ±15V - Sets Miller effect magnitude and EMI filtering needs |
| tF | 5.8ns / 22ns - Defines minimum dead-time requirement to prevent shoot-through |
| RθJA | 69°C/W - Achievable only with 1-inch² thermal pad on bottom layer; 105°C/W without |

Key Features
| Feature | Design Value |

| Complementary Pair Integration | Single-package N+P pairing eliminates layout mismatch and reduces board area by >40% vs discrete solutions |
| Low RDS(ON) Asymmetry | Q1/Q2 on-resistance ratio = 25/28 = 0.89 - Enables balanced conduction loss in bidirectional switches |
| Fast Body Diode Recovery | tRR = 5.6ns (N) / 10.4ns (P) - Minimizes reverse recovery loss in synchronous rectification |
| Thermal Pad Performance | RθJC = 15°C/W - Enables >1.5W dissipation with 30°C rise using standard FR-4 PCB |
| Green Compliance | Halogen-free, antimony-free, RoHS-compliant - Meets IPC-1752A Class 3 material declaration requirements |
Applications
| USB Power Delivery Switch | Industrial I/O Protection |
|---|---|
|
Use Scenario: Bidirectional 5–20V USB PD port protection with overcurrent and reverse-polarity blocking. IC Role / Device Role / Timing Role: Dual-channel load switch controlling VBUS path and CC line isolation; operates as back-to-back MOSFET pair. Use Value: Eliminates need for separate N/P drivers and level shifters; RDS(ON) < 30mΩ ensures <120mV drop at 4A. |
Use Scenario: 24V industrial digital input module with polarity reversal and surge protection. IC Role / Device Role / Timing Role: Complementary front-end switch enabling reverse-voltage blocking and hot-swap sequencing. Use Value: Integrated body diodes handle transient clamping; tF < 22ns prevents latch-up during ESD events. |
| DC-DC Synchronous Rectifier | Motor Driver Half-Bridge |
|
Use Scenario: Secondary-side synchronous rectification in isolated 12V→5V flyback converters. IC Role / Device Role / Timing Role: N-channel (high-side) and P-channel (low-side) rectifiers driven by transformer-coupled gate signals. Use Value: Matched Qg/RDS(ON) enables <92% efficiency at 5A; Coss < 160pF minimizes switching loss. |
Use Scenario: Low-power brushed DC motor control in battery-powered tools and actuators. IC Role / Device Role / Timing Role: Half-bridge driver stage where Q1 controls PWM high-side and Q2 provides freewheeling path. Use Value: Avalanche-rated EAS = 24mJ absorbs inductive kickback; tD(OFF) = 36ns allows precise dead-time tuning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVT-7 | Lower voltage rating (±20V), higher RDS(ON) (40mΩ/45mΩ), smaller 2×2mm package | Better suited for 5V/12V logic-level interfaces; insufficient for 24V industrial rails | Select when board space is constrained and voltage stress <20V; avoid for 30V bus applications. |
| SI6926ADQ-T1-GE3 | Same 30V rating but asymmetric packaging (SO-8), higher Qg (15nC/25nC), no thermal pad | Requires larger PCB footprint and external heatsinking for >1W operation | Choose if SO-8 compatibility is mandatory; expect 25°C higher junction temp at same current. |
Compared with DMC3025LNS-7, DMC2038LVT-7 trades voltage margin for size reduction, while SI6926ADQ-T1-GE3 sacrifices thermal performance for legacy package compatibility-neither matches the UXB's RθJA = 69°C/W or integrated thermal pad.

FAQ
What is the maximum safe operating junction temperature for DMC3025LNS-7?
The absolute maximum junction temperature is +150°C, validated across all operating conditions per DS38130 Rev. 3-2. Derating begins at +125°C ambient when mounted on 2oz copper with thermal bias; sustained operation above +135°C junction requires active cooling or reduced current.
Can DMC3025LNS-7 be used in a synchronous buck converter as both high-side and low-side switches?
No-it integrates an N-channel and P-channel MOSFET, not two N-channels. The P-channel device serves as a low-side switch but lacks the gate drive compatibility for standard N-channel synchronous buck controllers. It is appropriate for buck-derived topologies like floating-gate P-channel low-side or complementary PWM stages.
Does the POWERDI®3333-8 package require solder paste stencil adjustments versus standard SO-8?
Yes-the UXB package has a 3.3mm × 3.3mm body and exposed thermal pad requiring a 0.15mm-thick stencil with 70% aperture opening (0.23mm × 0.23mm) for optimal void control. Standard SO-8 stencils produce excessive solder volume and tombstoning risk on the 0.32mm lead width.
How does the gate threshold voltage mismatch between Q1 and Q2 affect turn-on timing?
Q1 VGS(TH) = +1.0–2.0V and Q2 VGS(TH) = −1.2–−2.4V create a natural 200–400mV turn-on offset, reducing simultaneous conduction risk. This inherent asymmetry simplifies dead-time design in complementary switching, eliminating need for external delay circuits.
