Product details
Overview
DMP3045LVT-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSOT26 package, rated for -30V VDSS, 42 mΩ RDS(ON) @ VGS = -10V, and -5.4A continuous drain current at TA = +25°C. It serves as a high-efficiency power switch in DC-DC converter high-side or load-switch configurations.
For engineers reviewing the DMP3045LVT-13 datasheet, DMP3045LVT-13 pinout, DMP3045LVT-13 application, or DMP3045LVT-13 equivalent, key selection criteria include gate threshold voltage (-1 to -2.1 V), low input capacitance (749 pF), fast switching times (tD(ON) = 4.4 ns), thermal resistance (RθJA = 104 °C/W), and AEC-Q101 readiness for automotive-grade power management.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) while maintaining controlled gate charge (Qg = 14.3 nC @ VGS = -10V) and low Crss (79 pF). Its body diode exhibits VSD = -0.7 to -1.2 V at IS = -1 A, supporting synchronous rectification in buck converters.
The device operates across -55°C to +150°C junction temperature range with ESD-protected gate (HBM > 2 kV), and is characterized for stable RDS(ON) performance up to 150°C (normalized drift < 1.8× at VGS = -10V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage in high-side switch or reverse-polarity protection circuits |
| RDS(ON) | 42 mΩ @ VGS = -10V - Enables ≤100 mW conduction loss at 5 A, critical for thermally constrained PCBs |
| ID (max) | -5.4 A @ TA = +25°C - Supports compact 5–6 A load switches without heatsinking on standard FR-4 |
| Ciss | 749 pF - Low input capacitance reduces gate drive power and enables >1 MHz switching in point-of-load regulators |
| tD(ON) | 4.4 ns - Fast turn-on delay minimizes overlap loss in synchronous buck topologies |
| RθJA | 104 °C/W - Thermal limit defines safe continuous operation at ~1.15 W dissipation on minimal copper pad layout |
| VGS(TH) | -1 to -2.1 V - Logic-level compatible with 3.3 V or 5 V microcontroller GPIO for direct drive |
Pinout & Package
Package: TSOT26 - 6-pin ultra-thin surface-mount package (2.9 × 1.6 × 0.6 mm), RoHS-compliant matte tin finish, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (P-channel) | Common return path for load current; tied to system ground or positive rail depending on topology |
| 2 (Gate) | Control input | Accepts negative VGS to enhance channel; requires level-shifting for high-side floating drive |
| 3 (Drain) | Power output node | Connects to load or inductor; handles full switched current and blocking voltage |
| 4 (Source) | Source terminal (redundant) | Internally bonded to Pin 1; improves current sharing and thermal conduction in high-current layouts |
| 5 (Drain) | Drain terminal (redundant) | Internally bonded to Pin 3; enhances current handling and reduces package inductance |
| 6 (Drain) | Drain terminal (redundant) | Internally bonded to Pins 3 & 5; provides third drain connection for optimal thermal and electrical performance |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 65 mΩ @ VGS = -4.5V enables efficient 3.3 V–controlled load switching without gate driver IC |
| ESD-protected gate | HBM > 2 kV rating allows safe handling and assembly in non-ESD-controlled environments |
| Low Qgd/Qg ratio | Qgd = 3 nC / Qg = 14.3 nC = 0.21 - Reduces Miller-induced shoot-through risk in hard-switched converters |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive environmental compliance |
| Thermal robustness | RθJC = 19.6 °C/W supports direct thermal pad attachment to PCB copper for enhanced power cycling reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | RDS(ON) = 50 mΩ @ -4.5 V; higher Ciss (920 pF); same TSOT26 package | Marginally slower switching; less suitable for >500 kHz DC-DC topologies | Prefer for cost-sensitive 12 V automotive loads where 50 mΩ RDS(ON) is acceptable |
| AO3415 | RDS(ON) = 48 mΩ @ -4.5 V; lower Qg (11.5 nC); no AEC-Q101 qualification | Lacks automotive change control and PPAP support; not recommended for safety-critical modules | Choose for commercial-grade consumer power switches requiring faster gate drive |
Compared with DMG3415L-7 and AO3415, DMP3045LVT-13 delivers superior RDS(ON) at -4.5 V (65 mΩ vs. 50/48 mΩ), tighter VGS(TH) tolerance, and formal AEC-Q101 qualification-making it the preferred choice for thermally demanding, automotive-compliant designs.

FAQ
Is DMP3045LVT-13 qualified to AEC-Q101?
Yes, DMP3045LVT-13 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It supports PPAP documentation and change control required for automotive applications, including body electronics and infotainment power stages.
What is the maximum safe operating temperature for continuous use?
The junction temperature must not exceed +150°C. With RθJA = 104 °C/W on standard FR-4 (2 oz Cu, minimum pad), the device supports continuous 1.2 W dissipation at +25°C ambient-equivalent to ~5.4 A at 42 mΩ under ideal thermal conditions.
Can DMP3045LVT-13 be driven directly from a 3.3 V microcontroller GPIO?
Yes. Its VGS(TH) range of -1 to -2.1 V ensures reliable enhancement at VGS = -3.3 V. However, gate drive strength must overcome Qg = 14.3 nC to achieve specified switching speeds; a 10–22 Ω series resistor is recommended for ringing suppression.
Does this MOSFET include integrated ESD protection?
Yes, the gate is ESD-protected per HBM Class 2 (>2 kV), verified per JESD22-A114. This eliminates need for external gate protection diodes in most board-level ESD environments, simplifying layout and reducing BOM count.
