Product details
Overview
DMP2170U-13 from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in SOT23 package, featuring 90mΩ RDS(ON) at VGS = −4.5V, −3.1A continuous drain current, and AEC-Q101 qualification for automotive-grade reliability-used in battery charging circuits and portable DC-DC converters.
For engineers reviewing the DMP2170U-13 datasheet, DMP2170U-13 pinout, DMP2170U-13 application, or DMP2170U-13 equivalent, key selection criteria include low-voltage gate drive compatibility (−2.5V threshold), thermal resistance (99°C/W on 1-in² copper), body diode recovery (5.5ns tRR), and RoHS/Green compliance for space-constrained power stages.
Technical Context
This P-channel MOSFET operates with a gate threshold voltage of −1.01V (typ), enabling robust turn-on with logic-level or low-voltage microcontroller outputs. Its 303pF input capacitance and 3.6nC total gate charge support fast switching in high-frequency buck and load-switch topologies.
The device integrates a low-leakage body diode (VSD = −0.8V typ at −1A) and exhibits normalized RDS(ON) variation ≤1.4× over −55°C to +150°C junction range-critical for thermally demanding portable power adaptors and automotive accessory modules.
Key Specifications

| RDS(ON) | 90mΩ @ VGS = −4.5V: Delivers <120mW conduction loss at 3.1A, enabling >92% efficiency in 5V-input buck converters. |
| ID (max) | −3.1A @ TA = +25°C: Rated for sustained operation in compact 1.28W thermal envelope with 1-in² copper pad. |
| tRR | 5.5ns: Minimizes reverse-recovery energy loss during synchronous rectification in high-frequency DC-DC stages. |
| Ciss | 303pF: Enables clean gate drive with standard 6Ω series resistor and <20ns rise/fall times under typical layout conditions. |
| Qg | 3.6nC @ VGS = −4.5V: Allows efficient driving from low-power GPIOs without external buffer in always-on load switch applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48mΩ @ −4.5V (lower), but ID = −4.2A (higher); Ciss = 510pF (larger) | Better for high-current, lower-frequency loads; less suitable for >1MHz switching due to higher gate charge | Select when conduction loss dominates and gate drive strength permits higher Qg. |
| AO3401 | RDS(ON) = 85mΩ @ −4.5V (slightly lower); not AEC-Q101 qualified; RθJA = 120°C/W (worse) | Cost-optimized for consumer electronics; unsuitable for automotive or extended-temperature industrial use | Select only for non-automotive, commercial-temperature applications where qualification is not required. |
Compared with DMG2305U-7 and AO3401, DMP2170U-13 offers balanced trade-offs: tighter thermal performance (99°C/W), automotive qualification, and optimized gate charge for mid-frequency switching-making it preferred for space- and reliability-constrained portable power designs.

FAQ
What is the maximum safe operating junction temperature for DMP2170U-13?
The absolute maximum junction temperature is +150°C, validated per JEDEC JESD22-A104. Operation above this limit risks permanent parametric shift or bond-wire failure. Derating is required above +125°C ambient-thermal design must ensure RθJA × PD + TA ≤ 150°C using the 99°C/W value for 1-in² copper.
Can DMP2170U-13 be used in a high-side switch configuration with 3.3V GPIO control?
No-direct 3.3V GPIO cannot drive the gate relative to source in high-side mode. A level-shifting circuit or dedicated high-side driver is required because VGS must be negative relative to source. For true 3.3V-compatible high-side switching, consider an integrated load switch IC instead.
Is the body diode in DMP2170U-13 suitable for synchronous rectification?
Yes-the body diode has 5.5ns reverse recovery time and −0.8V forward voltage at −1A, making it viable for synchronous rectification in low-duty-cycle, high-frequency DC-DC converters up to ~1MHz. However, external Schottky diodes remain preferable above 1.5MHz due to lower QRR.
Does DMP2170U-13 require special PCB layout considerations for thermal performance?
Yes-achieving the 99°C/W RθJA rating requires a 1-inch square copper pour on the SOT23 drain pad, connected via ≥4 thermal vias to inner ground planes. Without this, RθJA degrades to 163°C/W, limiting continuous current to ~1.8A at +70°C ambient.
