Product details
Overview
DMN1002UCA6 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a 6-terminal CSP package, designed for high-efficiency load switching and battery protection. It delivers 2.36 mΩ RSS(ON) at VGS = 3.8 V, supports 24.4 A continuous source current at 25°C, and features integrated ESD protection on gate terminals. Its ultra-low profile (0.11 mm height) and compact 3.05 mm × 1.77 mm footprint enable use in space-constrained portable power systems.
For engineers reviewing the DMN1002UCA6 datasheet, DMN1002UCA6 pinout, DMN1002UCA6 application, or DMN1002UCA6 equivalent, key selection criteria include its dual-source configuration, sub-3 mΩ on-resistance at low gate drive (≤3.8 V), thermal resistance of 50.7°C/W under optimized layout, and qualification for battery management ICs requiring tight voltage headroom and fast transient response.
Technical Context
This device integrates two matched N-channel MOSFETs in a single X4-DSN3118-6 chip-scale package with shared gate control logic and independent source terminals. Its dual-source architecture enables synchronous rectification or back-to-back switch configurations without external paralleling.
The MOSFET operates with a gate threshold voltage of 0.35–1.4 V and maintains stable RSS(ON) across –55°C to +150°C junction temperature, supported by low Crss (198–297 pF) and Qgd (16.0–24.0 nC) for efficient high-frequency switching in DC-DC converters and smart load switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VSSS | 12 V - Maximum source-source blocking voltage defines safe operation in 3.3 V–12 V battery rail applications. |
| RSS(ON) Typ | 2.36 mΩ @ VGS = 3.8 V - Enables ≤90 mV conduction drop at 38 A, critical for low-voltage battery protection FETs. |
| IS Max | 24.4 A @ TA = 25°C - Sustains high pulsed load currents in USB PD and power bank output stages. |
| Qg Typ | 45.7 nC - Low total gate charge reduces driver power loss and enables use with low-current GPIO-based control. |
| RθJA | 50.7 °C/W - Achieved with minimum recommended FR-4 pad layout; enables 2.47 W power dissipation in thermally constrained PCBs. |
| VGS(TH) | 0.35–1.4 V - Ultra-low threshold supports direct interface with 1.8 V/2.5 V logic and battery-fuel-gauge ICs. |
Pinout & Package
Package: X4-DSN3118-6 - 6-terminal chip-scale package, 3.05 mm × 1.77 mm × 0.11 mm, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source 1 | Primary current return path for Channel 1; electrically isolated from Source 2 for differential sensing or back-to-back topology. |
| 2 | Gate 1 | Control input for first MOSFET channel; ESD-protected to ±8 V, compatible with 1.8 V logic drive. |
| 3 | Source 1 | Second connection to same Source 1 node; reduces bondwire inductance and improves current sharing in high-di/dt paths. |
| 4 | Source 2 | Independent return path for Channel 2; enables dual-rail switching or reverse-current blocking in battery protection ICs. |
| 5 | Gate 2 | Separate gate terminal allows asynchronous control of second channel or tied to Gate 1 for parallel operation. |
| 6 | Source 2 | Redundant Source 2 connection; lowers thermal resistance and improves solder joint reliability under high-cycle stress. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel configuration | Two matched MOSFETs in one die enable back-to-back switch topologies for bidirectional current blocking in battery packs. |
| Ultra-low RSS(ON) at low VGS | 2.36 mΩ @ 3.8 V ensures <100 mV drop at 40 A, minimizing power loss in 5 V–12 V portable power rails. |
| 0.11 mm profile | Enables integration beneath thin-profile batteries or displays where Z-height is limited to <0.15 mm. |
| ESD-protected gate | Withstands ±8 V HBM ESD without external protection, reducing BOM count in handheld device front-end switches. |
| Halogen- and antimony-free | Meets automotive "Green" standards (<900 ppm Br/Cl, <1000 ppm Sb), supporting compliance in consumer and industrial designs. |
Applications
| Battery Protection Circuit | USB-C Power Delivery Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN10H260SFD-13 | Single N-channel, 2.6 mΩ @ 4.5 V, SO-8 package (4.9 × 6.0 mm), 1.75 mm height | Larger footprint and height; lacks dual-source isolation; requires external gate resistors for paralleling | Choose when board area is unconstrained and only one switch channel is needed with higher thermal mass. |
| AOB2012L | Dual N-channel, 2.2 mΩ @ 4.5 V, DFN3×3-8L package (3.0 × 3.0 mm), 0.8 mm height | 0.69 mm taller; uses standard DFN pads instead of CSP; no integrated ESD protection on gates | Prefer when existing DFN reflow profiles are standardized and external TVS diodes are already deployed. |
Compared with DMN1002UCA6, DMN10H260SFD-13 offers higher thermal mass but sacrifices space efficiency and dual-source flexibility, while AOB2012L matches on-resistance but increases Z-height by 610% and adds external ESD design overhead.

FAQ
What is the maximum continuous current rating for DMN1002UCA6 at 70°C ambient?
The DMN1002UCA6 supports 19.6 A continuous source current at TA = +70°C when VGS = 4.5 V, per the Absolute Maximum Ratings table. This derating reflects thermal limits under standard FR-4 mounting with 1-inch² copper pour, and must be validated against actual PCB layout and airflow conditions.
Can Gate 1 and Gate 2 be driven independently?
Yes - Pins 2 and 5 are electrically isolated gate terminals, allowing independent control of each channel. The datasheet's Equivalent Circuit diagram confirms separate gate connections, enabling asymmetric switching for applications like active OR-ing or programmable current limiting.
Is DMN1002UCA6 qualified for automotive applications?
No - the datasheet explicitly states that automotive-qualified versions (AEC-Q101) require special change control and PPAP capability, and this part number is not listed among Diodes' AEC-qualified MOSFETs. It is intended for industrial and consumer applications only.
What is the recommended PCB pad layout for optimal thermal performance?
Diodes specifies a minimum recommended pad layout for the X4-DSN3118-6 package on its package outline page. For 50.7°C/W RθJA, use full-solder coverage on all six terminals with thermal vias under the exposed source pads, connected to internal ground planes per IPC-7351B Type C guidelines.
