Product details
Overview
DMP1070UCA3-7A from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for low-RDS(ON) and fast switching in compact power management circuits. It delivers 70 mΩ @ VGS = −4.5 V, −3.6 A continuous drain current at +25°C, and −12 V drain-source breakdown voltage - enabling high-efficiency load switching in space-constrained battery-powered systems.
For engineers reviewing the DMP1070UCA3-7A datasheet, DMP1070UCA3-7A pinout, DMP1070UCA3-7A application, or DMP1070UCA3-7A equivalent, key selection criteria include gate threshold voltage (−0.40 to −0.95 V), ultra-low profile (0.22 mm height), ESD-protected gate (4 kV HBM), and thermal resistance (92.2 °C/W under recommended layout).
Technical Context
This MOSFET operates as a single P-channel switch with depletion-free enhancement-mode behavior, requiring negative gate drive relative to source. Its low Qg (1.45 nC) and Qgd (0.28 nC) support efficient high-frequency PWM control in DC-DC converters and load switches.
The device integrates an intrinsic body diode with VSD = −0.7 to −1.0 V at −0.4 A and exhibits RDS(ON) variation of <±15% over −55°C to +150°C junction temperature - critical for stable operation in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −12 V - supports 12 V rail switching without avalanche stress |
| RDS(ON) | 70 mΩ @ VGS = −4.5 V - enables <0.1 W conduction loss at 3.6 A |
| ID (continuous) | −3.6 A @ TA = +25°C - sufficient for USB-C PD load switches and battery protection FETs |
| Qg | 1.45 nC - reduces gate drive power and switching transition time |
| RθJA | 92.2 °C/W - achievable with minimum FR-4 pad layout per datasheet Figure 5 |
| VGS(TH) | −0.66 V typical - ensures reliable turn-on with standard logic-level controllers |
| HBM ESD | 4 kV - eliminates need for external gate protection in handheld designs |
Pinout & Package
Package: X4-DSN0607-3 - ultra-thin 0.6 mm × 0.7 mm, 3-terminal leadless package with NiPdAu-plated terminals and 0.22 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (S) | Common reference node for gate drive; connected to higher potential in P-channel configuration |

| ESD-protected gate | 4 kV HBM rating - eliminates external TVS diodes in portable electronics |
| Low gate charge | Qg = 1.45 nC - reduces driver IC power consumption and heat generation |
| Thermally enhanced layout | Exposed drain pad - improves PCB heat spreading and lowers RθJA to 92.2 °C/W |
| Halogen- and antimony-free | <900 ppm Br/Cl, <1000 ppm Sb - meets IPC-1752a Class 3 environmental compliance |
Applications
| Battery Protection Circuit | USB-C Power Delivery Switch |
|---|---|
|
Use Scenario: Reverse-current blocking and overcurrent shutdown in Li-ion battery packs. IC Role / Device Role / Timing Role: High-side P-channel switch controlled by battery management IC to isolate cell stack during fault conditions. Use Value: 70 mΩ RDS(ON) limits voltage drop to <250 mV at 3.6 A, preserving battery runtime and thermal margin. |

Use Scenario: Isolation of charging circuitry from main system during sleep mode in hearables and fitness trackers. IC Role / Device Role / Timing Role: Compact, low-height load switch placed adjacent to battery connector. Use Value: 0.22 mm height prevents interference with flex cable routing and housing clearance constraints. |
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 |
|---|---|---|---|
| DMN1070UCB-7 | Same RDS(ON) (70 mΩ @ −4.5 V) but larger X2-DSN1006-3 package (1.0 × 0.6 mm, 0.35 mm height) | Less suitable for ultra-thin wearables due to 59% greater height and 67% larger footprint | Select when board assembly uses reflow profiles incompatible with X4-DSN0607-3's fine-pitch terminals |
| Si2301DDS-T1-GE3 | Higher RDS(ON) (115 mΩ @ −4.5 V), lower ID (−2.7 A), no HBM ESD rating specified | Requires external gate protection and heatsinking in >2 A applications | Choose only if cost sensitivity outweighs reliability and size requirements |
Compared with DMN1070UCB-7 and Si2301DDS-T1-GE3, DMP1070UCA3-7A provides the smallest form factor with certified ESD robustness and lowest thermal resistance - making it optimal for next-generation portable devices where board area and reliability are co-constrained.

FAQ
What is the maximum safe operating junction temperature for DMP1070UCA3-7A?
The device is rated for TJ = −55°C to +150°C. At +150°C, RDS(ON) increases by ~35% versus room temperature (per Figure 6), and continuous ID derates to −2.4 A at TA = +70°C (per Maximum Ratings table). Thermal design must maintain TJ ≤ 150°C under worst-case ambient and power dissipation.
Can DMP1070UCA3-7A be used in automotive applications?
While not AEC-Q101 qualified, the device meets key automotive-environment requirements: operation to +150°C, 4 kV HBM ESD rating, and halogen/antimony-free construction. For production automotive use, Diodes offers AEC-Q101 variants like DMP1070UCA3Q-7A - contact Diodes or Aetrix for PPAP-capable versions.
What is the recommended PCB pad layout for X4-DSN0607-3 package?
Per Diodes' package outline DS39833 Rev. 5-2 page 6, the recommended pad layout uses C = 0.40 mm, C1 = 0.35 mm, X = 0.15 mm, X1 = 0.25 mm, Y = 0.15 mm, Y1 = 0.50 mm, with solder mask defined pads and thermal relief for the exposed drain. This layout achieves RθJA = 92.2 °C/W.
Does DMP1070UCA3-7A have a built-in body diode, and what is its forward voltage?
Yes - it includes an integrated parasitic body diode with VSD = −0.7 V (typical) to −1.0 V (max) at −0.4 A and TJ = +25°C (per Electrical Characteristics table). The diode is unidirectional and conducts from source to drain when VDS > 0, enabling reverse-current blocking functionality.
