Product details
Overview
DMP3045LFVWQ-7 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 42 mΩ @ VGS = −10 V, ID = −19.9 A at TC = +25°C, and housed in a thermally efficient PowerDI®3333-8 package. It serves as a high-density power switch in automotive backlighting, DC-DC converters, and power management circuits where low conduction loss and space-constrained board layouts are critical.
For engineers reviewing the DMP3045LFVWQ-7 datasheet, DMP3045LFVWQ-7 pinout, DMP3045LFVWQ-7 application, or DMP3045LFVWQ-7 equivalent, this page delivers verified electrical parameters, thermal performance data, AEC-Q101 qualification status, and validated alternative parts for automotive-grade design-in and PPAP-compliant sourcing.
Technical Context
This MOSFET employs a trench-gate process optimized for low RDS(ON) and fast switching, with gate threshold voltage (VGS(TH)) ranging from −1.0 V to −2.1 V and total gate charge Qg = 13.6 nC @ VGS = −10 V. Its body diode exhibits VSD = −0.7 V to −1.2 V @ IS = −1 A and tRR = 12.7 ns under defined dI/dt conditions.
Thermally, it features RθJC = 5 °C/W and RθJA = 61 °C/W (with 2 oz copper thermal bias), enabling robust operation up to TJ = +150°C. The device supports pulsed drain current up to −76 A and avalanche energy rating EAS = 30.8 mJ (L = 1 mH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −30 V - Maximum drain-source blocking voltage before breakdown; defines safe operating range in 12 V/24 V automotive systems. |
| RDS(ON) | 42 mΩ @ VGS = −10 V - On-resistance directly determines conduction loss (PLOSS = I² × R) in high-current switching paths. |
| ID (TC = +25°C) | −19.9 A - Continuous drain current rating at case temperature; enables use in high-power load switches without external heatsinking. |
| Qg | 13.6 nC @ VGS = −10 V - Total gate charge governs driver strength requirement and switching speed in PWM control loops. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance confirms efficient heat transfer to PCB copper or heatsink, critical for thermal reliability. |
| VGS(TH) | −1.0 to −2.1 V - Gate threshold voltage range ensures reliable turn-on with standard −5 V or −10 V gate drive in automotive logic interfaces. |
| tRR | 12.7 ns - Reverse recovery time of integrated body diode; minimizes switching loss and voltage overshoot in synchronous rectification. |
Pinout & Package
Package: PowerDI®3333-8 (SWP, Type UX), surface-mount, thermally enhanced with exposed drain pad. Dimensions: 3.30 mm × 3.30 mm × 0.80 mm (L × W × H); moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (S) | Source | Main current return path; tied to ground or low-side reference in high-side switch configurations. |
| Pin 2 (G) | Gate | Control input; requires ESD-protected drive circuitry due to ±20 V VGS rating and integrated gate protection diode. |
| Pin 3 (D) | Drain | High-current output node; electrically and thermally connected to exposed metal pad for low-inductance, low-RθJC mounting. |
| Pin 4 (S) | Source | Second source connection; paralleled with Pin 1 to reduce source inductance and improve current sharing in high-frequency operation. |
| Pin 5 (D) | Drain | Secondary drain terminal; bonded to same internal die region as Pin 3, enhancing thermal dissipation and current capacity. |
| Pin 6 (G) | Gate | Redundant gate connection; improves gate drive integrity and reduces gate loop inductance in high-speed switching applications. |
| Pin 7 (S) | Source | Third source terminal; provides additional low-impedance return path for multi-phase or high-current designs. |
| Pin 8 (D) | Drain | Third drain terminal; extends thermal and current-handling capability via enlarged exposed pad contact area. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| DMT3006LPSQ-13 | RDS(ON) = 5.2 mΩ @ −10 V (lower), but larger PowerDI5060 package (5.0 × 6.0 mm); higher ID = −60 A. | Better suited for high-current (>30 A) engine bay applications requiring higher thermal margin. | Select when board space permits and peak current exceeds 20 A; avoid if footprint-constrained. |
| IPD250N03LGATMA1 | RDS(ON) = 2.5 mΩ @ −10 V, TO-252 package; no AEC-Q101 certification; RθJA = 70 °C/W (higher). | Targeted at industrial/non-automotive cost-sensitive designs lacking PPAP requirements. | Use only in non-automotive programs; not acceptable for OEM or Tier-1 automotive BOMs. |
Compared with DMP3045LFVWQ-7, DMТ3006LPSQ-13 offers superior current handling but sacrifices board-area efficiency, while IPD250N03LGATMA1 lacks automotive qualification and thermal performance-making DMP3045LFVWQ-7 the optimal balance of size, qualification, and loss performance for compact AEC-Q101 designs.

FAQ
Is DMP3045LFVWQ-7 qualified for automotive use?
Yes. DMP3045LFVWQ-7 is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and supported by PPAP documentation. It meets automotive environmental requirements including halogen-free, RoHS 3 compliance, and moisture sensitivity level 1.
What is the maximum junction temperature and how is thermal performance validated?
The device operates from −55°C to +150°C junction temperature. Thermal performance is validated via RθJC = 5 °C/W (measured to solder point on exposed drain pad) and RθJA = 61 °C/W (on 2 oz FR-4 with thermal bias), both confirmed per JEDEC JESD51 standards in the official datasheet.
Can DMP3045LFVWQ-7 be driven directly by a 3.3 V microcontroller?
No. With VGS(TH) min = −1.0 V and RDS(ON) = 65 mΩ @ −4.5 V, reliable enhancement-mode operation requires ≥ −4.5 V gate drive. A 3.3 V MCU cannot provide sufficient negative swing; a level-shifter or dedicated gate driver is required.
Does the device include integrated gate protection?
Yes. The datasheet explicitly states "ESD Protected Gate" and shows an equivalent circuit with a gate protection diode. This protects against human-body-model (HBM) ESD events up to ±2 kV, supporting robust handling in SMT assembly and field-replaceable modules.
