Product details
Overview
DMP2165UW-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT323 package, rated for -20V VDSS, 90mΩ RDS(ON) @ VGS = -4.5V, and -2.5A continuous drain current at TA = +25°C. It delivers low on-resistance and fast switching for compact power management circuits in space-constrained portable electronics.
For engineers reviewing the DMP2165UW-13 datasheet, DMP2165UW-13 pinout, DMP2165UW-13 application, or DMP2165UW-13 equivalent, key selection criteria include gate threshold voltage (-0.4 to -1.0V), junction-to-ambient thermal resistance (175°C/W under high-copper layout), body diode forward voltage (-0.7 to -1.1V), total gate charge (3.5nC), and safe operating area limits for pulsed loads.
Technical Context
This device operates as a single P-channel switch with depletion-free enhancement-mode behavior, requiring negative gate drive relative to source. Its low RDS(ON) at -4.5V gate bias enables efficient load switching in battery-powered systems where supply headroom is limited.
The MOSFET integrates a monolithic body diode with reverse recovery time of 9ns and QRR of 1.5nC, supporting synchronous rectification and flyback energy recirculation in DC-DC converters and motor H-bridge half-bridges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum drain-source blocking voltage before avalanche conduction |
| RDS(ON) | 90mΩ @ VGS = -4.5V - On-resistance determines I²R conduction loss in load-switching path |
| ID (max) | -2.5A @ TA = +25°C - Continuous current capability under standard PCB thermal conditions |
| VGS(TH) | -0.4 to -1.0V - Gate threshold range defines minimum negative bias needed to initiate channel conduction |
| Qg | 3.5nC - Total gate charge governs required drive strength and switching transition time |
| Ciss | 335pF - Input capacitance affects gate driver loading and high-frequency stability |
| tRR | 9ns - Reverse recovery time of integrated body diode critical for snubberless flyback and buck-boost topologies |
Pinout & Package
SOT323 surface-mount package with 3 terminals: Drain (D), Gate (G), Source (S). Molded plastic case meets UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | High-side switched output node | Connected to load return or supply rail; carries full load current and withstands full VDSS during off-state |
| G (Gate) | Control input | Receives negative voltage relative to source to turn on; requires <3.5nC charge for full enhancement |
| S (Source) | Reference terminal | Biased at system ground or positive rail; serves as return path for gate drive and body diode conduction |
Key Features
| Feature | Design Value |
|---|---|

| Fast switching speed | Turn-on delay 3.7ns + rise time 8.7ns supports >1MHz PWM in compact DC-DC regulators |
| Low input/output leakage | IDSS ≤ -1.0µA @ VDS = -20V ensures minimal standby current in always-on power rails |
| Green packaging | Halogen- and antimony-free compound (<900ppm Br/Cl, <1000ppm Sb) meets RoHS 3 and JEDEC green standards |

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 @ VGS = -4.5V; higher ID max = -4.2A; same SOT323 package | Higher current handling suits larger motors but increases gate charge (6.5nC) and cost | Select when >2.5A continuous load or lower conduction loss is required |
| AO3401 | RDS(ON) = 85mΩ @ VGS = -4.5V; PD = 1.4W; TO-236AB (SOT23) package | Larger thermal mass improves power dissipation but occupies 2.9 × 1.3mm vs. SOT323's 2.2 × 2.15mm | Select when board-level thermal relief is prioritized over footprint size |
Compared with DMG2305U-7 and AO3401, the DMP2165UW-13 offers optimal balance of ultra-compact SOT323 footprint, moderate gate charge (3.5nC), and verified 9ns body diode recovery-making it preferred for space-limited, medium-current, high-frequency load switching where thermal budget is managed via layout.

FAQ
What is the maximum allowable gate-source voltage for DMP2165UW-13?
The absolute maximum VGS is ±12V per the datasheet's Maximum Ratings table. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be clamped between -12V and 0V, with recommended bias of -4.5V for full enhancement and minimal RDS(ON).
Can DMP2165UW-13 be used in place of an N-channel MOSFET in high-side switching?
No-it is a P-channel device designed for high-side switching without level shifting, unlike N-channel MOSFETs that require gate voltage above the source. Its -20V VDSS and -1.0V typical VGS(TH) allow direct logic-level control from 3.3V or 5V microcontrollers when source is tied to VCC.
Does DMP2165UW-13 have a built-in ESD protection diode?
No dedicated on-chip ESD protection diode is specified in the datasheet. The device meets HBM ESD rating of ±2kV (per JEDEC JESD22-A114), achieved through process-level design-not discrete protection structures. External TVS or RC filtering is recommended for board-level ESD robustness in handheld applications.
How does junction temperature affect RDS(ON) performance?
RDS(ON) increases with junction temperature: Figure 6 shows ~1.6× increase from -55°C to +150°C at VGS = -4.5V. At 125°C, RDS(ON) rises to ~140mΩ-requiring derating of continuous current to ~1.8A to maintain thermal stability on standard FR-4 layouts.
