Product details
Overview
DMP1080UCB4-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a 1.0 mm × 1.0 mm U-WLB1010-4 chip-scale package, rated for -12 V VDSS, 65 mΩ RDS(ON) at VGS = -4.5 V, and 2.5 nC total gate charge, optimized for compact battery protection and load switching circuits.
For engineers reviewing the DMP1080UCB4-7 datasheet, DMP1080UCB4-7 pinout, DMP1080UCB4-7 application, or DMP1080UCB4-7 equivalent, key selection criteria include low-threshold turn-on (-0.6 V typ.), ultra-low profile (0.62 mm height), JEDEC-qualified reliability, and CSP footprint compatibility with space-constrained portable power rails.
Technical Context
This MOSFET employs LD-MOS technology to achieve a low figure of merit (RDS(ON) × Qg = 162.5 mΩ·nC), enabling high-efficiency operation in bidirectional blocking configurations. Its -0.6 V typical VGS(TH) supports direct interfacing with 1.8 V/3.3 V logic without level shifting.
The device features ESD protection rated to 3 kV HBM on the gate terminal and operates across -55 °C to +150 °C junction temperature range. Thermal resistance RθJA is 150 °C/W on FR-4 with minimum pad layout, confirming suitability for thermally constrained PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -12 V - Maximum drain-source voltage before avalanche breakdown; defines safe operating ceiling in battery-input circuits. |
| RDS(ON) | 65 mΩ @ VGS = -4.5 V - On-resistance directly determines conduction loss in load-switch applications at nominal bias. |
| Qg | 2.5 nC - Total gate charge governs drive strength requirement and switching transition time in PWM-controlled paths. |
| VGS(TH) | -0.6 V typ. - Gate threshold enables reliable turn-on from low-voltage microcontrollers and PMIC outputs. |
| Package | U-WLB1010-4 - 1.0 mm × 1.0 mm × 0.62 mm wafer-level CSP; supports fine-pitch routing and minimal board area usage. |
| TJ Range | -55 °C to +150 °C - Validated junction temperature range ensures robustness in automotive cabin and industrial battery environments. |
Pinout & Package
U-WLB1010-4 is a 4-terminal wafer-level chip-scale package with bottom-side solderable terminals. The device uses a standard source-drain-gate configuration with no exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Top-left) | Source | Main current return path; tied to system ground or battery negative in high-side switch topologies. |
| Terminal 2 (Top-right) | Drain | Power input/output node; connects to battery anode or protected load rail in reverse-polarity protection. |
| Terminal 3 (Bottom-right) | Source | Second source connection; paralleled internally with Terminal 1 to reduce package resistance and improve current sharing. |
| Terminal 4 (Bottom-left) | Gate | Control input; requires <1.0 V overdrive margin for full enhancement due to -0.6 V VGS(TH). |
Key Features
| Feature | Design Value |
|---|---|
| LD-MOS process technology | Delivers industry-leading RDS(ON) × Qg figure of merit (162.5 mΩ·nC), minimizing both conduction and switching losses simultaneously. |
| Ultra-low profile | 0.62 mm maximum height enables integration into slim consumer wearables and stacked PCB assemblies where Z-height is constrained. |
| 3 kV HBM ESD rating | Protects gate oxide during board handling and assembly, reducing field failure risk in unshielded portable electronics production. |
| JEDEC-qualified reliability | Meets AEC-Q200 stress test requirements for passive components, supporting use in automotive-grade power management modules. |
Applications
| Battery Protection Circuit | USB-C Power Path Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN10H015LPS-13 | RDS(ON) = 15 mΩ @ -4.5 V but larger 2.0 mm × 2.0 mm SO-8 package; Qg = 12.5 nC. | Higher current capacity (-15 A) but unsuitable for sub-2 mm² layouts; better for high-power industrial loads. | Select when >5 A continuous current is required and board area permits SO-8 mounting. |
| AO3415 | RDS(ON) = 50 mΩ @ -4.5 V in SOT-23; Qg = 3.9 nC; VGS(TH) = -1.0 V min. | Requires higher gate drive voltage; less suitable for 1.8 V logic interfaces; lower thermal performance (RθJA = 200 °C/W). | Choose only if SOT-23 reflow compatibility is mandatory and gate drive voltage ≥2.5 V is available. |
Compared with DMN10H015LPS-13 and AO3415, DMP1080UCB4-7 uniquely balances ultra-compact size, low-threshold logic compatibility, and JEDEC reliability-making it optimal for space- and voltage-constrained portable battery systems where thermal headroom is limited.

FAQ
What is the maximum continuous drain current for DMP1080UCB4-7 at 70°C ambient?
At TA = +70°C with VGS = -4.5 V, the continuous drain current is -2.7 A. This value is derived from thermal derating based on RθJA = 150 °C/W and PD = 0.82 W, ensuring safe operation without exceeding TJ = +150°C under standard FR-4 mounting conditions.
Does DMP1080UCB4-7 support reverse battery protection?
Yes-its -12 V VDSS rating and P-channel topology allow it to block reverse polarity when placed in the high-side position. When the battery is inserted backward, the body diode remains reverse-biased, and the channel stays off unless actively driven, preventing damage to downstream circuitry.
Is the U-WLB1010-4 package compatible with standard reflow profiles?
Yes-the U-WLB1010-4 package is qualified for lead-free reflow per J-STD-020, supporting peak temperatures up to 260°C. Its copper pillar interconnects and mold compound withstand standard Pb-free thermal cycles without delamination or solder joint fracture.
Can DMP1080UCB4-7 be used in automotive cabin modules?
While not AEC-Q101 qualified, DMP1080UCB4-7 meets JEDEC high-reliability standards and operates from -55°C to +150°C. For automotive cabin applications below engine bay temperature grades, it may be deployed subject to customer qualification-Diodes offers AEC-Q101 variants (e.g., DMP1080UCB4Q) with PPAP support.
