Product details
Overview
DMN22M5UCA10-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET optimized for low-RDS(ON) and high-efficiency power switching in compact battery management systems. It delivers 3.1 mΩ typical RSS(ON) at VGS = 3.8 V, supports 26.5 A continuous source current at +25°C, and features a 24 V VSSS rating - enabling use as a high-current load switch in space-constrained portable electronics.
For engineers reviewing the DMN22M5UCA10-7 datasheet, DMN22M5UCA10-7 pinout, DMN22M5UCA10-7 application, or DMN22M5UCA10-7 equivalent, key selection criteria include ultra-low-profile CSP packaging (0.120 mm height), gate ESD protection, thermal resistance of 39.8 °C/W under recommended layout, and compatibility with 2.5–4.5 V logic-level drive in battery protection circuits.
Technical Context
This dual-source MOSFET uses a trench-gate silicon process to achieve sub-4 mΩ on-resistance while maintaining fast switching performance: tD(ON) = 326 ns and Qg = 40.7 nC at VDD = 12 V. Its integrated gate protection diode and ±12 V VGSS rating support robust operation in transient-prone battery paths.
The device operates across –55°C to +150°C junction temperature range and exhibits stable VGS(TH) (0.4–1.3 V) and RSS(ON) over temperature - critical for reliable overcurrent detection and thermal foldback in load-switch ICs and smart battery packs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VSSS | 24 V - Maximum source-source blocking voltage for 2-cell Li-ion battery stack protection |
| RSS(ON) Typ | 3.1 mΩ @ VGS = 3.8 V - Enables <100 mW conduction loss at 18 A, reducing thermal stress in thin PCBs |
| IS Continuous | 26.5 A @ TA = +25°C - Supports high-current USB-C PD power path and e-fuse applications |
| Qg | 40.7 nC - Determines gate driver strength requirement for <1 µs turn-on in synchronous buck controllers |
| RθJA | 39.8 °C/W - Measured on FR-4 with minimum pad layout; defines heatsinking needs for 0.96 W steady-state dissipation |
| VGS(TH) | 0.4–1.3 V - Ensures turn-on with standard 1.8 V/3.3 V I/O, compatible with low-voltage microcontroller GPIO |
| Ciss | 3490 pF - Impacts high-frequency gate drive losses and EMI in DC-DC converter sync-FET applications |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Source 1 | Primary current return path; electrically tied to Source 2 for paralleled low-inductance conduction |
| 3 | Gate | Control input with integrated ESD protection diode to Source; requires <12 V max drive |
| 6, 7, 9, 10 | Source 2 | Secondary source connection; combined with Source 1 to reduce package inductance and improve current sharing |
| 8 | Gate 2 | Not applicable - single-gate device; Pin 8 is unused (no internal connection) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile CSP | 0.120 mm height enables integration beneath batteries or in stacked modules where Z-height is constrained |
| Logic-level gate threshold | VGS(TH) down to 0.4 V ensures reliable turn-on with 1.8 V microcontrollers without level-shifting circuitry |
| Integrated gate ESD protection | Withstands >2 kV HBM per JESD22-A114 - eliminates need for external TVS in portable product ESD test compliance |
| Lead-free & halogen-free | RoHS 3 and "Green" compliant (Br+Cl <1500 ppm, Sb <1000 ppm) - meets automotive and medical regulatory requirements |
| Low thermal resistance | RθJA = 39.8 °C/W on minimal FR-4 pad - allows 0.96 W power dissipation without heatsink in handheld devices |
Applications
| Battery Protection Circuit | USB-C Power Delivery Path |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2020LFG-7 | RDS(ON) = 4.5 mΩ @ 4.5 V; larger DFN2020 package (2.0 × 2.0 mm); no integrated gate ESD diode | Higher thermal resistance (RθJA = 100 °C/W); less suitable for ultra-thin wearables | Choose when cost sensitivity outweighs height constraint and external ESD protection is acceptable |
| AOZ8802DI | Integrated eFuse with current sensing; RDS(ON) = 5.2 mΩ; 2.5 × 2.5 mm QFN package | Includes overcurrent flag and thermal shutdown - adds functionality but increases BOM count and footprint | Choose when programmable current limiting and fault reporting are required beyond basic switching |
Compared with DMN22M5UCA10-7, DMN2020LFG-7 trades lower cost for higher on-resistance and taller profile, while AOZ8802DI replaces discrete switching with intelligent protection - making DMN22M5UCA10-7 optimal for minimal-footprint, high-current, logic-level-driven load switching where system-level intelligence resides elsewhere.

FAQ
What is the maximum gate-source voltage rating for DMN22M5UCA10-7?
The absolute maximum VGS rating is ±12 V, as specified in the Maximum Ratings table. Exceeding this voltage risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 0–4.5 V in standard logic-level applications, with transient spikes clamped by the integrated gate protection diode to Source.
Can DMN22M5UCA10-7 be used in automotive applications?
DMN22M5UCA10-7 is not AEC-Q101 qualified per its datasheet. While it meets RoHS 3 and operates from –55°C to +150°C, Diodes explicitly states that automotive-grade versions require PPAP capability and IATF 16949 manufacturing - which this part does not carry. It is intended for industrial and consumer applications only.
How does the dual-source terminal configuration affect PCB layout?
The four-source terminals (Pins 1,2,4,5 and 6,7,9,10) must be connected to the same low-impedance copper pour to minimize current imbalance and parasitic inductance. The recommended pad layout specifies symmetric thermal vias and equal-length traces to both source groups - critical for achieving the rated 26.5 A current and 39.8 °C/W thermal resistance.
Is there a recommended gate resistor value for switching applications?
No fixed gate resistor is specified, but design guidance indicates that Rg = 281 Ω (typical) is intrinsic to the device. External gate resistance should be selected based on desired dV/dt control and EMI targets - typically 1–10 Ω for high-speed switching or 10–47 Ω for reduced ringing in noise-sensitive battery systems.
