Product details
Overview
DMP1008UCB9 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a Chip-Scale Package (U-WLB1515-9), rated for -8V VDSS, 5.7mΩ RDS(ON) at VGS = -4.5V, and -13.2A continuous drain current at TA = +25°C. It serves as a high-efficiency load switch or synchronous rectifier in compact DC-DC converters and battery management systems.
For engineers reviewing the DMP1008UCB9 datasheet, DMP1008UCB9 pinout, DMP1008UCB9 application, or DMP1008UCB9 equivalent, key selection criteria include its ultra-low RDS(ON) per mm² footprint, 8.2nC total gate charge for fast switching, -0.6V typical gate threshold voltage, and CSP thermal performance with RθJA = 82°C/W on optimized PCB.
Technical Context
This MOSFET employs third-generation Lateral DMOS (LD-MOS) technology to achieve low figure-of-merit (RDS(ON) × Qg = 46.7 mΩ·nC), enabling high power density in space-constrained applications. Its -0.6V VGS(TH) supports direct logic-level drive from 1.8V/2.5V/3.3V controllers without level shifting.
The U-WLB1515-9 package features nine solderable terminals with SnAgCu finish, 0.60mm height, and 1.5mm × 1.5mm footprint. Thermal resistance is optimized via copper pillar interconnects and direct die-to-PCB heat transfer-confirmed by RθJA = 82°C/W on 1-inch² 2oz Cu FR-4.
Key Specifications

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) = 1.5mΩ @ -4.5V but in larger TSOP-6 (3.05mm × 1.65mm); Qg = 12.5nC | Higher current capacity (-30A) but 2.7× larger footprint and higher gate drive demand | Select when board area permits and higher current headroom is required |
| AO3401 | RDS(ON) = 52mΩ @ -4.5V in SOT-23; Qg = 3.5nC; VDSS = -30V | Lower cost but 9× higher conduction loss; suitable only for ≤1A loads | Select only for cost-sensitive, low-current applications where thermal budget allows |
Compared with DMN10H015LPS-13 and AO3401, DMP1008UCB9 uniquely balances ultra-low RDS(ON), minimal footprint, and logic-level drive-making it optimal for space-constrained, high-efficiency 3–5A power rails where thermal resistance and gate charge directly impact system efficiency.

FAQ
What is the maximum safe operating junction temperature for DMP1008UCB9?
The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C. Derating begins at +70°C ambient for continuous operation on standard FR-4; thermal design must ensure TJ remains below 150°C under worst-case load and airflow conditions.
Does DMP1008UCB9 require a gate resistor for stability?
A gate resistor is recommended to dampen ringing caused by parasitic inductance in high-speed switching. Typical values range from 5Ω to 22Ω depending on driver strength and layout; 10Ω is validated in the datasheet for tD(ON) and tD(OFF) measurements with minimal overshoot.
Can DMP1008UCB9 be used in automotive applications?
DMP1008UCB9 is not AEC-Q101 qualified. For automotive use, Diodes offers pin-compatible AEC-Q101 variants such as DMP1008UCB9Q-7 (qualified per AEC-Q101 Rev G); contact Diodes or Aetrix for PPAP-ready automotive-grade sourcing.
How does the U-WLB1515-9 package affect PCB layout and reflow?
The U-WLB1515-9 requires precise stencil aperture design (0.12mm thickness, 0.25mm × 0.25mm openings) and reflow profile targeting peak temperature of 245°C for 30–60 seconds. Diodes provides recommended pad layout (1.0mm × 1.0mm solder mask defined) to prevent tombstoning and ensure void-free solder joints.
