Product details

Overview

DMP1070UCA3 from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for low-R_DS(ON) and fast switching in compact power management circuits. It delivers 70 mΩ @ V_GS = −4.5 V, −3.6 A continuous drain current at +25°C, and operates with −12 V V_DSS, targeting battery protection and load-switching functions in space-constrained portable electronics.

For engineers reviewing the DMP1070UCA3 datasheet, DMP1070UCA3 pinout, DMP1070UCA3 application, or DMP1070UCA3 equivalent, key selection criteria include gate threshold voltage (−0.40 to −0.95 V), thermal resistance (92.2 °C/W under recommended layout), ESD rating (4 kV HBM), and its X4-DSN0607-3 0.22 mm profile package for high-density PCB integration.

Technical Context

This MOSFET employs a trench-gate process to achieve low on-resistance while maintaining controlled gate charge (Q_g = 1.45 nC) and low reverse transfer capacitance (C_rss = 30 pF). Its −0.66 V typical V_GS(TH) enables reliable turn-on from standard logic-level negative gate drive.

The device integrates an intrinsic body diode with V_SD = −0.7 to −1.0 V at −0.4 A and exhibits normalized R_DS(ON) variation of ≤1.8× across −55°C to +150°C junction temperature, supporting stable operation in thermally dynamic battery systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−12 V - Withstands up to −12 V drain-source blocking voltage without breakdown.
R_DS(ON)	70 mΩ @ V_GS = −4.5 V - Enables <0.1 W conduction loss at 3.6 A, critical for efficiency in battery-fed loads.
I_D (continuous)	−3.6 A @ T_A = +25°C - Supports sustained 3.6 A load switching on FR-4 PCB with minimum pad layout.
Q_g	1.45 nC - Reduces gate drive power and switching transition time in high-frequency PWM control.
V_GS(TH)	−0.40 to −0.95 V - Ensures robust turn-on with common −3.3 V or −5 V logic-compatible gate drivers.
R_θJA	92.2 °C/W - Specifies thermal rise per watt under recommended single-sided FR-4 layout, guiding heatsinking decisions.
ESD Rating	4 kV HBM - Protects gate oxide during handling and board assembly without external clamping.

Pinout & Package

Package: X4-DSN0607-3 - ultra-thin (0.22 mm height), 3-terminal leadless package with NiPdAu or NiAu terminations, footprint 0.60 × 0.69 mm, pitch 0.40 mm.

3 (Drain)	Power output	Switched high-side or low-side power node; connects to battery cathode or load return in protection circuits.

Key Features

Feature	Design Value
Low Q_g & Q_gd	1.45 nC total gate charge and 0.28 nC gate-drain charge minimize Miller-induced switching delay and EMI.
0.22 mm profile	Enables stacking with other ultra-thin components in slim consumer devices like wearables and hearing aids.
ESD-protected gate	4 kV HBM rating eliminates need for external gate protection diodes in most production environments.
Lead-free & green	Fully RoHS 3 compliant with <900 ppm Br+Cl and <1000 ppm Sb, meeting automotive and medical regulatory requirements.

Applications

Battery Protection Circuit

Load Switch for Portable Device

Use Scenario: Reverse-current and overcurrent protection in Li-ion battery packs for tablets and power banks.

IC Role / Device Role / Timing Role: High-side P-MOSFET switch controlling battery cathode connection; activated only when system voltage and current are within safe limits.

Use Value: 70 mΩ R_DS(ON) limits voltage drop to <260 mV at 3.6 A, preserving battery runtime and reducing thermal stress on adjacent cells.

Use Scenario: Controlled power-up sequencing for USB-C peripheral modules in docking stations.

IC Role / Device Role / Timing Role: Low-side load switch enabling/disabling 3.3 V or 5 V rail to downstream ICs based on host controller command.

Use Value: −0.66 V typical V_GS(TH) ensures clean turn-on with standard GPIO, while 0.22 mm height avoids interference with stacked connectors.

Smartphone Power Path Management

Wireless Earbud Charging Case

Use Scenario: Dual-path power routing between USB input and battery during charging in smartphones.

IC Role / Device Role / Timing Role: P-MOSFET used in ideal diode configuration to prevent backfeed and enable seamless source selection.

Use Value: Low C_iss (147 pF) and C_rss (30 pF) reduce gate drive burden and improve transient response during path switching.

Use Scenario: Isolating battery from charging circuitry during earbud insertion/removal in compact charging cases.

IC Role / Device Role / Timing Role: Compact load switch placed between case battery and earbud charging contacts to prevent leakage and accidental discharge.

Use Value: X4-DSN0607-3 footprint (0.60 × 0.69 mm) fits tight spacing between battery and PCB edge, enabling sub-20 mm case thickness.

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
DMN10H023LPS-13	R_DS(ON) = 23 mΩ @ V_GS = −4.5 V; larger TSOP-6 package (1.6 × 2.9 mm); higher I_D = −8.5 A	Suitable for higher-current industrial load switching where board area is less constrained	Select when >3.6 A continuous current or lower R_DS(ON) is required, accepting larger footprint and higher cost
AO3401	R_DS(ON) = 85 mΩ @ V_GS = −4.5 V; SOT-23 package (2.9 × 1.6 mm); 1.1 mm height	Compatible with legacy SOT-23 footprints but lacks 4 kV HBM ESD rating and green compliance	Choose for cost-sensitive, non-automotive designs where existing SOT-23 layout reuse is prioritized over miniaturization and reliability

Compared with DMN10H023LPS-13 and AO3401, DMP1070UCA3 uniquely balances ultra-low profile (0.22 mm), industry-leading ESD robustness (4 kV HBM), and green compliance in a 0.6 × 0.7 mm footprint-making it optimal for next-gen wearable and hearable power switches where vertical stack height and regulatory alignment are critical.

FAQ

What is the maximum continuous drain current for DMP1070UCA3 at +70°C ambient?

At T_A = +70°C, the DMP1070UCA3 supports −2.9 A continuous drain current when V_GS = −4.5 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations under standard FR-4 mounting conditions with minimum recommended copper area.

Does DMP1070UCA3 require external gate resistors for typical load-switch applications?

No external gate resistor is required for basic on/off load switching at frequencies below 100 kHz. The device's low Q_g (1.45 nC) and integrated ESD protection allow direct GPIO or microcontroller drive; however, a 10–100 Ω series resistor is recommended if EMI reduction or ringing suppression is needed in high-speed PWM use.

Can DMP1070UCA3 be used in automotive-grade designs?

DMP1070UCA3 is not AEC-Q101 qualified. While it meets RoHS 3 and green standards, Diodes specifies that automotive applications require explicit qualification-contact Diodes or an authorized representative for PPAP-capable, IATF 16949-manufactured alternatives such as the DMP1045UFD-7.

How does the X4-DSN0607-3 package affect solder reflow profile requirements?

The X4-DSN0607-3 package has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH without baking. Reflow must follow Diodes' recommended profile: peak temperature ≤260°C, time above 217°C ≤60 seconds, with ramp rates ≤3°C/s to avoid die attach voiding or package warpage.
