Product details

Overview

DMN16M9UCA6-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in a 6-pin CSP package (X3-DSN2718-6 Type B), rated for 12 V V_SSS, 6.5 mΩ R_SS(ON) at V_GS = 4.5 V, and 16.6 A continuous source current at T_A = +25°C. It serves as a low-profile load switch or battery protection device in space-constrained portable electronics.

For engineers reviewing the DMN16M9UCA6-7 datasheet, DMN16M9UCA6-7 pinout, DMN16M9UCA6-7 application, or DMN16M9UCA6-7 equivalent, key selection criteria include ultra-low on-resistance at low gate drive (2.5–4.5 V), ESD-protected gate, sub-0.25 mm height, and thermal performance under FR-4 PCB mounting conditions.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for simultaneous low R_SS(ON) and fast switching, with gate threshold voltage (V_GS(TH)) tightly specified between 0.5 V and 1.3 V. Its dynamic parameters-C_iss = 2360 pF, Q_g = 35.2 nC, and t_F = 3812 ns-are calibrated for efficient operation in high-frequency DC-DC and battery-switching topologies.

The device integrates intrinsic body diode functionality with V_SS(diode) = 0.7–1.2 V at I_S = 3 A and exhibits normalized R_SS(ON) variation of ≤1.5× across −55°C to +150°C junction temperature, enabling stable performance in wide-temperature industrial and automotive cabin applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_SSS	12 V - Maximum blocking voltage for battery-side switching in single-cell Li-ion systems.
R_SS(ON)	6.5 mΩ @ V_GS = 4.5 V - Enables <100 mW conduction loss at 12 A, critical for thermal budget in thin PCBs.
I_S (cont.)	16.6 A @ T_A = +25°C - Supports high-current load switching without external heatsinking on standard FR-4.
Q_g	35.2 nC - Determines gate driver power requirement and switching transition time in PWM control loops.
R_θJA	51.5 °C/W - Measured with minimum recommended pad layout; defines maximum power dissipation before thermal derating.
Package	X3-DSN2718-6 (Type B) - 2.70 × 1.81 × 0.21 mm CSP footprint compatible with fine-pitch automated assembly.

Pinout & Package

Package: X3-DSN2718-6 (Type B), 6-terminal chip-scale package with NiPdAu-plated terminals, moisture sensitivity level 1 per J-STD-020.

G1	Gate 1	Main gate input; ESD-protected structure enables robust handling in low-voltage portable manufacturing.
S2	Source 2	Secondary source connection; parallel routing reduces package inductance and improves current sharing.
G2	Gate 2	Redundant gate terminal; improves gate drive uniformity and mitigates bond-wire resistance effects.
S3	Source 3	Third source terminal; enhances thermal spreading and lowers effective R_DS(on) in PCB layout.
M2 / MC	Marking Code Pad	Non-functional test pad used for laser marking; not connected to internal circuitry.

Key Features

Feature	Design Value

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	R_SS(ON) = 9.5 mΩ @ V_GS = 4.5 V; 10 V V_SSS; same X3-DSN2718-6 package	Lower voltage rating limits use to sub-10 V systems; higher R_SS(ON) increases conduction loss by ~46% at 12 A	Select when 10 V max blocking suffices and cost sensitivity outweighs efficiency requirements.
AOZ1280CI	Integrated gate driver, thermal shutdown, and enable logic; SO-8 package; 15 V V_SSS	Requires external control signals; larger footprint and height preclude ultra-thin designs	Choose when system-level protection features (OTP, UVLO) and ease of drive are prioritized over size and raw efficiency.

Compared with DMN10H5D0L-7 and AOZ1280CI, DMN16M9UCA6-7 delivers the lowest R_SS(ON) in the smallest form factor, making it optimal for thermally constrained, high-current battery-switching roles where discrete control and minimal bill-of-materials are required.

FAQ

What is the maximum continuous drain current for DMN16M9UCA6-7 at 70°C ambient?

At T_A = +70°C and V_GS = 4.5 V, the continuous source current is 13.2 A. This value is derived from thermal derating based on R_θJA = 51.5 °C/W and P_D = 2.4 W under minimum pad layout conditions, ensuring safe operation without exceeding T_J = 150°C.

Does DMN16M9UCA6-7 require external gate resistors for typical load-switch applications?

No external gate resistor is required for basic on/off switching at frequencies below 100 kHz. The device's Q_g = 35.2 nC and low C_iss/C_rss ratio allow clean turn-on with standard 3.3 V MCU GPIOs. A 10 Ω series resistor may be added only if EMI reduction or dV/dt control is needed in high-noise environments.

Can DMN16M9UCA6-7 be used in bidirectional current flow applications?

Yes-the MOSFET's intrinsic body diode supports reverse current flow from source to drain when V_SS < 0 V, enabling use in battery charging paths and OR-ing configurations. However, forward conduction through the body diode incurs ~0.7–1.2 V drop; synchronous rectification requires external control of a second FET.

Is the X3-DSN2718-6 package compatible with standard reflow profiles for lead-free soldering?

Yes-this package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard SnAgCu reflow profiles with peak temperatures up to 260°C. The NiPdAu terminal finish ensures reliable wetting and intermetallic formation without voiding or dewetting on OSP- or ENIG-finished PCBs.
