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 +25°C. It delivers low on-resistance and fast switching in TSOT26 packaging, enabling 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), input capacitance (845pF), thermal resistance (74°C/W with copper pad), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters and LED drivers. Its -0.9V maximum VGS(th) ensures reliable turn-on with low-voltage logic control, while its 10.4nC total gate charge supports efficient high-frequency switching up to several hundred kHz.
The device uses a planar trench process to balance conduction loss and switching speed. Its TSOT26 package provides 0.0013g mass and UL 94V-0 flammability rating, with matte-tin-plated terminals solderable per MIL-STD-202 Method 208.

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) | Limited to lower-power loads (<2A continuous) due to thermal constraints | Select when board space permits larger SOT-23-6 footprint and thermal margin is sufficient |
| AO3401 | Higher RDS(ON) (85mΩ @ -4.5V); no AEC-Q101 qualification; 1000x larger production volume | Suitable for consumer-grade power switches where automotive reliability is not required | Choose for cost-sensitive non-automotive designs with relaxed thermal and qualification requirements |
Compared with DMN2033LSD-13 and AO3401, DMP2033UVT offers superior thermal performance (74°C/W vs. 125°C/W) and automotive qualification, making it optimal for space-constrained, high-reliability 3–4A load switching where gate drive voltage is ≥3.3V.

FAQ
What is the maximum safe operating junction temperature for DMP2033UVT?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Operation at this limit requires strict thermal design: 74°C/W RθJA implies ≤1.7W power dissipation with 1-inch² copper pad. Derating to 125°C junction is recommended for long-term reliability in automotive environments.
Can DMP2033UVT be driven directly by a 3.3V microcontroller GPIO?
Yes - its VGS(th) range of -0.5V to -0.9V ensures full enhancement with 3.3V logic swing (VGS = -3.3V). No level shifter or charge pump is needed. However, ensure the MCU can sink ≥10mA peak gate current during 10.4nC charging to achieve specified 6.5ns turn-on delay.
Does DMP2033UVT have integrated ESD protection?
No integrated ESD protection diode is specified in the datasheet. The device exhibits ±8V maximum gate-source voltage rating, indicating reliance on external TVS or RC filtering for gate protection in noisy environments such as automotive CAN/LIN bus proximity or motor drive PCBs.
How does the TSOT26 package compare thermally to standard SOT-23-6?
TSOT26 offers 27% lower RθJA (74°C/W vs. typical 102°C/W for SOT-23-6) due to exposed drain pads and optimized internal die attach. Its 1.00mm height also reduces board bending stress in automated assembly, critical for automotive module vibration tolerance.
