Product details
Overview
DMP2077UCA3 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a 1.0 mm × 0.6 mm DSN1006-3 package, rated for -20 V VDSS, 78 mΩ RDS(ON) at VGS = -8 V, and -4.0 A continuous drain current at TA = +25°C. It serves as a compact load switch or battery protection device in space-constrained mobile power rails.
For engineers reviewing the DMP2077UCA3 datasheet, DMP2077UCA3 pinout, DMP2077UCA3 application, or DMP2077UCA3 equivalent, key selection criteria include its ultra-low profile (0.20 mm height), low gate charge (Qg = 1.34 nC), and guaranteed RDS(ON) performance down to -55°C junction temperature - critical for portable battery management and always-on power domains.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage of -0.85 V (typical), enabling reliable turn-on from standard logic-level negative gate drive. Its low output capacitance (Coss = 76 pF) and fast switching times (tF = 5.4 ns) support high-frequency load switching up to several MHz in DC-DC post-regulation and USB port power control.
The device integrates an intrinsic body diode with VSD = -0.73 V (typical) at IS = -0.5 A and exhibits normalized RDS(ON) variation of ≤1.4× across -55°C to +150°C, confirming stable conduction in thermally aggressive handheld environments.
Key Specifications

Applications
| Battery Protection Circuit | USB Type-C Port Power Switch |
|---|---|
Use Scenario: Overvoltage and overcurrent cutoff in single-cell Li-ion battery packs. IC Role / Device Role / Timing Role: High-side P-channel MOSFET acting as reverse-polarity and charge/discharge path controller. Use Value: 78 mΩ RDS(ON) limits voltage drop to <300 mV at 3.5 A, preserving battery runtime and thermal margin. | Use Scenario: VBUS enable/disable per USB PD specification in portable accessories. IC Role / Device Role / Timing Role: Load switch isolating downstream 5 V rail during fault or standby. Use Value: 1.34 nC Qg allows clean 100 µs turn-on/off transitions using standard microcontroller GPIOs. |

IC Role / Device Role / Timing Role: Low-leakage (IDSS ≤ -100 nA) hold-off switch preventing self-discharge. Use Value: -100 nA IDSS at -16 V ensures <1 µA quiescent loss over 6-month shelf life. |
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 |
|---|---|---|---|
| DMN2077LFG-7 | Same X4-DSN1006-3 package but N-channel; requires high-side driver or charge pump | Not directly substitutable without gate drive redesign; better for low-side switching topologies | Select only if existing design uses N-channel high-side configuration with integrated driver |
| AO3415 | SO-8 package (4.9 mm × 6.0 mm); RDS(ON) = 50 mΩ @ VGS = -10 V; larger footprint and height | Acceptable where board space permits and lower RDS(ON) justifies size penalty | Choose when thermal budget demands <50 mΩ and PCB real estate is unconstrained |
Compared with DMN2077LFG-7 and AO3415, DMP2077UCA3 uniquely delivers logic-compatible P-channel switching in the smallest industry-standard footprint, eliminating need for external level shifters while maintaining sub-0.2 mm profile - essential for next-generation ultra-thin mobile devices.

FAQ
What is the maximum safe operating junction temperature for DMP2077UCA3?
The absolute maximum junction temperature is +150°C, and the device is characterized for RDS(ON) stability across this full range. Thermal resistance RθJA is 197°C/W on FR-4 with minimum pad layout, meaning 0.66 W power dissipation raises junction temperature by ~130°C above ambient - thus limiting practical continuous use to ≤+25°C ambient unless enhanced cooling is applied.
Does DMP2077UCA3 require a gate resistor for typical GPIO-driven switching?
A series gate resistor is recommended to dampen ringing and limit peak gate current, especially at >1 MHz switching. With Qg = 1.34 nC and typical MCU GPIO drive strength (~20 mA), a 10 Ω resistor yields ~67 ns RC time constant - sufficient for clean edges without excessive delay. No resistor is strictly required for DC on/off control.
Can DMP2077UCA3 be used in automotive cabin applications?
While DMP2077UCA3 meets AEC-Q200 passive stress testing requirements and is manufactured in IATF 16949-certified facilities, it is not officially AEC-Q101 qualified. For production automotive cabin use (e.g., infotainment power rails), Diodes recommends contacting their automotive team for PPAP-capable variants such as the AEC-Q101-compliant DMP2077UCA3-A.
How does the body diode forward voltage affect reverse-current protection?
VSD = -0.73 V (typical) at -0.5 A means the intrinsic body diode conducts with ~730 mV forward drop when reverse-biased - useful for reverse-polarity protection but insufficient alone for high-efficiency back-powering prevention. For true bidirectional blocking, a second MOSFET or dedicated protection IC must be added in series.
