Product details
Overview
DMP2035UVT-13 from Diodes Incorporated is a -20V P-channel enhancement-mode MOSFET in TSOT26 package, featuring 35mΩ RDS(ON) at VGS = -4.5V, -6.0A continuous drain current, and ESD protection to 3kV. It serves as a high-efficiency power switch in low-voltage DC-DC converters and motor control circuits where compact size and low conduction loss are critical.
For engineers reviewing the DMP2035UVT-13 datasheet, DMP2035UVT-13 pinout, DMP2035UVT-13 application, or DMP2035UVT-13 equivalent, key selection criteria include verified RDS(ON) at -2.5V gate drive, thermal resistance (RθJA = 65°C/W with 1-inch2 copper), body diode forward voltage (VSD = -0.7V @ -1A), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This P-channel MOSFET operates with a gate threshold voltage (VGS(TH)) of -0.4V to -1.5V and exhibits strong temperature stability: RDS(ON) increases only ~1.5× from -55°C to +150°C at fixed VGS. Its low input capacitance (Ciss = 1610–2400pF) and fast switching (tD(ON) = 17–33ns, tF = 42–64ns) support high-frequency synchronous rectification.
The integrated body diode has VSD = -0.7V at -1A and reverse recovery charge QRR = 4–8nC, enabling efficient freewheeling in buck converters and H-bridge motor drivers. Thermal design is supported by RθJC = 11.8°C/W and validated steady-state power dissipation of 2.0W on FR-4 with enhanced copper area.

FAQ
What is the maximum safe operating junction temperature for DMP2035UVT-13?
The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C. Derating begins at TA > +70°C per the datasheet's continuous current curves; thermal design must maintain TJ ≤ 150°C under worst-case power dissipation and ambient conditions.
Can DMP2035UVT-13 be driven directly by a 3.3V microcontroller GPIO?
No - as a P-channel MOSFET, it requires a gate voltage *lower* than the source to turn on. With source at 5V or 12V, a 3.3V GPIO cannot pull the gate sufficiently negative. A level-shifting circuit or dedicated gate driver is required unless the source is at 3.3V and gate is pulled to GND.
Is the body diode in DMP2035UVT-13 suitable for reverse polarity protection?
Yes - the integrated body diode blocks reverse current when the drain is biased negative relative to the source. For reverse polarity protection, connect source to input and drain to load; the diode conducts only during correct polarity, limiting forward drop to VSD ≈ -0.7V at rated current.
Does DMP2035UVT-13 require external gate resistors for reliable switching?
A gate resistor (typically 5–22Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss) and PCB inductance. The datasheet specifies tD(ON)/tF test conditions using RG = 6Ω, confirming that moderate gate resistance ensures clean edges and EMI control without sacrificing speed.
