Product details
Overview
DMN16M7UCA6-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET optimized for ultra-low on-resistance (3.4 mΩ @ VGS = 3.8 V) and high-current capability (19.2 A at TA = +25°C), housed in a 2.70 mm × 1.81 mm CSP package with 0.12 mm profile. It serves as a high-efficiency load switch or battery protection device in space-constrained portable electronics.
For engineers reviewing the DMN16M7UCA6-7 datasheet, DMN16M7UCA6-7 pinout, DMN16M7UCA6-7 application, or DMN16M7UCA6-7 equivalent, key selection criteria include its 12 V VSSS, ±8 V gate rating, ESD-protected gate, thermal resistance of 58.4 °C/W under standard FR-4 layout, and compatibility with low-voltage gate drive down to 2.5 V.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve sub-4 mΩ RSS(ON) while maintaining fast switching performance (Qg = 45.4 nC, tF = 4.7 ns). Its low-profile DSN2718-6 package enables direct integration into battery management ICs and compact power rails.
The device features a body diode with VFSS = 0.7–1.2 V at 3 A and exhibits stable threshold voltage (VGS(TH) = 0.5–1.3 V) across −55°C to +150°C, supporting robust operation in automotive and industrial environments where thermal cycling is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VSSS | 12 V - Maximum source-source blocking voltage; defines safe operating range in 3.3 V/5 V/12 V battery systems. |
| RSS(ON) | 3.4 mΩ @ VGS = 3.8 V - Enables <100 mW conduction loss at 18 A, critical for thermal budget in thin PCBs. |
| IS Max | 19.2 A @ TA = +25°C - Supports high-current load switching without external heatsinking on minimal copper area. |
| Qg | 45.4 nC - Determines gate driver current requirement; enables efficient PWM control up to ~1 MHz with moderate drive strength. |
| RθJA | 58.4 °C/W - Measured on FR-4 with 1 in² 2 oz Cu; defines junction-to-ambient rise per watt under standard layout. |
| VGS(TH) | 0.7 V Typ - Ensures reliable turn-on with 2.5 V logic-level gate drive, compatible with modern PMICs and microcontrollers. |
| Ciss | 2333 pF - Impacts high-frequency switching losses and EMI behavior in DC-DC converter output stages. |

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 |
|---|---|---|---|
| DMN10H5D0L-7 | RSS(ON) = 4.5 mΩ @ 4.5 V; higher VSSS = 10 V; same X4-DSN2718-6 package. | Lower voltage rating restricts use to ≤5 V systems; better suited for 3.3 V logic-driven battery switches. | Select when gate drive is fixed at 4.5 V and system voltage is capped at 5 V; avoid in 12 V BMS nodes. |
| AOZ1280CI | Integrated load switch IC (with enable, fault flag, soft-start); RDS(ON) = 5.2 mΩ; SO-8 package (4.9 × 6.0 mm). | Larger footprint and added control logic increase board area but simplify system-level protection design. | Choose when diagnostic signaling (OCP/OTP flag) and soft-start are required; not suitable for space-limited CSP-only layouts. |
Compared with DMN10H5D0L-7, the DMN16M7UCA6-7 delivers 24% lower RSS(ON) at 3.8 V drive and supports 12 V systems, while versus AOZ1280CI it trades integrated features for 75% smaller footprint and direct gate control-ideal for custom BMS firmware implementations.

FAQ
What is the maximum continuous current rating for DMN16M7UCA6-7 at 70°C ambient?
The DMN16M7UCA6-7 supports 15.4 A continuous source current at TA = +70°C with VGS = 4.5 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits under standard FR-4 PCB conditions (1 in² 2 oz Cu), not package intrinsic capability.
Does DMN16M7UCA6-7 require external gate resistors for typical load-switch operation?
No external gate resistor is required for basic on/off switching at frequencies below 100 kHz. The device's low Qg (45.4 nC) and gate capacitance allow direct drive from most microcontroller GPIOs; however, a 10 Ω series resistor is recommended to dampen ringing in high-di/dt (>5 A/ns) applications.
Can DMN16M7UCA6-7 be used in automotive-grade designs?
While DMN16M7UCA6-7 is not AEC-Q101 qualified, Diodes offers automotive-grade variants (e.g., DMN16M7UCA6Q-7) with PPAP documentation and IATF 16949 manufacturing. For non-automotive applications, its −55°C to +150°C operating range and robust ESD protection support industrial and medical use cases.
How does the dual-gate (G1/G2) structure impact PCB layout?
The G1 and G2 terminals are internally shorted, so both must be connected to the same gate drive net. Layout best practice is to route symmetric traces from the driver to each gate pad, minimizing loop inductance and ensuring balanced gate charge distribution-critical for simultaneous turn-on of all internal parallel cells.
