Product details
Overview
DMP3164LVT-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in TSOT26 package, rated for -30V VDSS, 95mΩ RDS(ON) @ VGS = -10V, and -2.8A continuous drain current at TA = +25°C. It delivers low conduction loss and fast switching for compact DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMP3164LVT-7 datasheet, DMP3164LVT-7 pinout, DMP3164LVT-7 application, or DMP3164LVT-7 equivalent, key selection criteria include dual-channel P-MOSFET integration, -4.5V logic-level gate drive compatibility, thermal resistance of 108°C/W (with copper pad), and RoHS-compliant green packaging for space-constrained portable power designs.
Technical Context
This dual P-channel MOSFET integrates two matched enhancement-mode transistors in a single TSOT26 package with independent source, gate, and drain terminals per channel. Its gate threshold voltage range (-0.7V to -2.1V) enables reliable turn-on with standard 3.3V/5V logic controllers.
The device features low input capacitance (Ciss = 324pF) and fast switching times (tD(ON) = 7.7ns, tF = 29.5ns), supporting high-frequency synchronous buck topologies. Thermal performance is optimized for FR-4 PCBs with 1-inch² copper plate (RθJA = 108°C/W).
Key Specifications

Applications
| LED Backlight Power Switch | USB-C Power Delivery Load Switch |
|---|---|
|
Use Scenario: Driving white LED strings in thin-profile LCD panels with PWM dimming at 1–20kHz. IC Role / Device Role: High-side P-MOSFET switch controlling current flow from 5V/12V supply to LED anode. Use Value: 95mΩ RDS(ON) limits I²R loss to <120mW at 1.2A, eliminating heatsink need in 5mm-height bezels. |
Use Scenario: Enabling/disabling VBUS on USB-C downstream ports during hot-plug detection. IC Role / Device Role: Dual-channel load switch providing independent control of VCONN and VBUS rails. Use Value: Independent G1/G2 pins allow staggered turn-on to suppress inrush current spikes beyond 3A peak. |
| Industrial Sensor Node PMIC | Portable Medical Device Power Sequencing |
|
Use Scenario: Power gating three isolated sensor subsystems (I²C, analog front-end, RF transceiver) in battery-powered IoT nodes. IC Role / Device Role: Dual P-MOSFET array acting as discrete enable switches with <1µA leakage (IDSS ≤ -1.0µA). Use Value: Ultra-low off-state leakage extends 200mAh coin-cell life by >18 months in sleep mode (typical 50nA system quiescent current). |
Use Scenario: Controlled power-up sequencing of analog signal chain (ADC, op-amps) and digital controller (MCU) in handheld diagnostics tools. IC Role / Device Role: Dual-channel high-side switch implementing time-delayed enable via RC-gated G1/G2 inputs. Use Value: Matched RDS(ON) ensures identical voltage drop across both channels, preventing sequencing skew >100ns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC3025LSD-13 | Single-channel, 30V, 2.5mΩ @ -10V, SO-8 package | Higher current density but no dual integration; requires two devices for same function | Preferred when board area allows SO-8 and RDS(ON) < 3mΩ is mandatory |
| AO4421 | Dual P-channel, -40V, 34mΩ @ -10V, SO-8 package | Higher voltage rating and lower RDS(ON), but larger footprint and higher Ciss (620pF) | Chosen when -40V blocking margin or <35mΩ conduction loss outweighs size constraints |
Compared with DMC3025LSD-13 and AO4421, the DMP3164LVT-7 offers optimal balance of miniaturization (TSOT26), logic-level gate drive (-4.5V), and thermal performance (108°C/W) for space-limited 3.3V/5V systems where dual-channel integration reduces component count by one device.

FAQ
What is the maximum safe operating junction temperature for DMP3164LVT-7?
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 when mounted on FR-4 with minimum pad layout (RθJA = 151°C/W); full-rated current (-2.8A) is maintained up to +70°C ambient with 1-inch² copper (RθJA = 108°C/W).
Can DMP3164LVT-7 be used in a synchronous buck converter as the high-side switch?
Yes - its -30V VDSS, -2.8A ID, and 95mΩ RDS(ON) @ -10V make it suitable for high-side switching in 5V-input buck converters. Gate drive must swing negative relative to source (e.g., using bootstrap or charge-pump circuitry), and body diode conduction should be minimized via precise timing control.
Does DMP3164LVT-7 support 3.3V logic-level gate drive?
Yes - with VGS(TH) ranging from -0.7V to -2.1V and RDS(ON) = 140mΩ @ VGS = -4.5V, it fully enhances using standard 3.3V GPIO (when referenced to source). For lowest RDS(ON), a -5V to -10V gate drive is recommended, achievable via simple inverting level shifter.
How does the TSOT26 package affect thermal performance compared to SO-8?
TSOT26 has higher thermal resistance than SO-8 (108°C/W vs. ~62°C/W), but achieves usable performance via optimized PCB layout: exposed drain pads (Pins 1 & 4) must connect directly to large copper areas. In 5mm × 5mm layouts, it delivers 0.83W dissipation - sufficient for 1.5A loads at +60°C ambient with proper copper fill.
