Product details
Overview
DMP2021UTSQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSSOP-8 package, rated for -20V VDSS, 16mΩ RDS(ON) @ VGS = -4.5V, and -18A continuous drain current at TC = +25°C. It is AEC-Q101 qualified, ESD-protected, and designed for automotive battery management and DC-DC converter high-side switching.
For engineers reviewing the DMP2021UTSQ-13 datasheet, DMP2021UTSQ-13 pinout, DMP2021UTSQ-13 application, or DMP2021UTSQ-13 equivalent, key selection criteria include gate threshold voltage (-0.35V to -1.0V), low RDS(ON) at low VGS, 100% unclamped inductive switching rating, and thermal resistance (RθJA = 95°C/W with 1-inch2 copper).
Technical Context
This MOSFET operates as a high-side load switch in automotive power rails, leveraging its low gate threshold (VGS(TH) down to -0.35V) to enable robust turn-on with 3.3V or 5V logic-level gate drive. Its integrated body diode supports synchronous rectification in buck converters.
The device features 100% UIS-rated avalanche capability (IAS = -25A, EAS = 32mJ), ensuring reliability under inductive load transients. Thermal design is supported by RθJC = 16°C/W and dual power dissipation ratings (0.9W on FR-4, 1.3W with enhanced copper).

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT6009LPS-13 | RDS(ON) = 9.5mΩ @ -4.5V but larger SO-8 package; higher Qg (52nC) | Better conduction loss but slower switching; less suitable for >200kHz DC-DC | Prefer when thermal headroom exists and lowest RDS(ON) dominates over switching speed |
| IPD80P03P4L-13 | VDSS = -30V, RDS(ON) = 3.4mΩ @ -10V; requires higher gate drive voltage | Over-spec'd voltage rating adds cost and gate drive complexity in 12V systems | Select only if future 24V system compatibility or higher surge margin is required |
Compared with DMT6009LPS-13 and IPD80P03P4L-13, DMP2021UTSQ-13 uniquely balances low-voltage gate drive compatibility, TSSOP-8 space savings, and verified UIS ruggedness-making it optimal for space-constrained, logic-driven automotive power switches where 20V blocking suffices.

FAQ
Is DMP2021UTSQ-13 suitable for hot-swap applications?
Yes. Its low gate threshold (-0.35V min), 100% UIS rating, and integrated ESD protection make it suitable for controlled hot-swap insertion in automotive modules. The device sustains repetitive inductive energy pulses up to 32mJ without degradation, and its tight VGS(TH) distribution ensures consistent turn-on timing during live insertion.
What is the maximum recommended gate resistor for PWM switching at 500kHz?
A 10Ω gate resistor is recommended for 500kHz operation. With Qg = 34nC and typical gate driver sink/source capability of ±2A, this yields ~170ns effective rise/fall time-well within the safe operating area defined in Figure 12 and compatible with the device's 125ns tD(OFF) and 96ns tF values.
Does DMP2021UTSQ-13 require external gate pull-down resistors in automotive MCU interfaces?
No external pull-down is required. The device's gate leakage (±10µA max) and low input capacitance (2760pF Ciss) allow direct connection to open-drain or push-pull MCU GPIOs. However, a 100kΩ pull-down is recommended in systems where MCU reset states are undefined to prevent unintended turn-on during boot.
How does the TSSOP-8 package perform thermally in reflow-soldered automotive PCBs?
When mounted per Diodes' recommended pad layout (1-inch² copper pour), the TSSOP-8 achieves RθJA = 95°C/W. At 1.3W dissipation, junction temperature rise is ~124°C above ambient-within the -55°C to +150°C operating range. No thermal vias are required, but 4–6 thermal vias under the exposed drain pads further reduce RθJA by ~15%.
