Product details
Overview
DMP2033UVT from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for high-efficiency power management, featuring -20V V(BR)DSS, 65mΩ RDS(ON) @ VGS = -4.5V, and -4.2A continuous drain current at TA = +25°C. It serves as a synchronous rectifier or load switch in compact DC-DC converters and backlighting circuits.
For engineers reviewing the DMP2033UVT datasheet, DMP2033UVT pinout, DMP2033UVT application, or DMP2033UVT equivalent, key selection criteria include gate threshold voltage (-0.5 to -0.9V), low input capacitance (845pF Ciss), fast switching (6.5ns tD(on)), thermal resistance (74°C/W RθJA with copper plate), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, requiring VGS ≤ -0.9V to fully enhance. Its low RDS(ON) at low gate drive (-2.5V) enables efficient operation in 3.3V- and 5V-controlled power rails.
The TSOT26 package supports high-density PCB layouts, and its internal structure integrates a body diode with VF ≈ 1.0V at IS = 10A and TJ = 125°C, enabling bidirectional current handling in buck or reverse-polarity protection topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -20V - Maximum drain-source blocking voltage before avalanche conduction |
| RDS(ON) | 65mΩ @ VGS = -4.5V, ID = -4.2A - On-resistance defining conduction loss in 5V-gate-driven loads |
| ID (continuous) | -4.2A @ TA = +25°C - Max steady-state current under standard FR-4 board conditions with 1-inch² copper |
| Ciss | 845pF - Input capacitance determining gate drive strength requirement and switching speed limit |
| tD(on) | 6.5ns - Turn-on delay time critical for high-frequency PWM operation above 1MHz |
| RθJA | 74°C/W - Thermal resistance with enhanced copper layout, enabling 1.7W dissipation at ambient |
| VGS(th) | -0.5 to -0.9V - Gate threshold range ensuring reliable turn-on with 3.3V logic-level drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2033LSD-13 | Same RDS(ON) spec (65mΩ @ -4.5V) but in SOT-23-6 package; higher RθJA (125°C/W) due to smaller pad area | Limited to lower-power applications (<1W dissipation); not AEC-Q101 qualified | Select when footprint compatibility with legacy SOT-23-6 designs is required and automotive qualification is unnecessary |
| Si2301DDS-T1-GE3 | Higher RDS(ON) (115mΩ @ -4.5V); lower Qg (5.2nC); same TSOT26 footprint | Better suited for ultra-low-power always-on circuits where gate drive energy matters more than conduction loss | Prefer when optimizing for battery-powered standby current rather than high-current efficiency |
Compared with DMN2033LSD-13 and Si2301DDS-T1-GE3, DMP2033UVT delivers superior thermal performance (74°C/W vs. 125°C/W) and automotive qualification, making it the only choice for thermally constrained or automotive-grade 4A load switching.

FAQ
What is the maximum safe operating junction temperature for DMP2033UVT?
The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C. Derating begins at TJ > 125°C, where RDS(ON) increases ~0.5%/°C. For continuous 4.2A operation, thermal design must maintain TJ ≤ 135°C using the 74°C/W RθJA value with enhanced copper layout.
Can DMP2033UVT be used in a high-side switch configuration with 5V gate drive?
No - as a P-channel device, DMP2033UVT requires the gate to be *lower* than the source to turn on. In high-side configuration (source tied to VIN), a gate voltage ≤ VIN – |VGS(th)| is needed. A 5V gate drive alone cannot achieve this without a charge pump or level shifter to generate a negative gate bias relative to source.
Does the body diode support continuous reverse current in synchronous rectification?
Yes - the intrinsic body diode has VF ≈ 1.0V at 10A and TJ = 125°C, and is rated for continuous forward current up to -3.4A at TA = +70°C. However, for optimal efficiency in synchronous rectification, the MOSFET channel should be actively driven during the diode conduction interval to minimize VF-related losses.
Is DMP2033UVT compatible with lead-free reflow profiles?
Yes - the TSOT26 package uses matte tin-plated terminals and is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. Moisture sensitivity level is Level 1, so no baking is required prior to assembly.
