Product details
Overview
DMP3045LVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDSS, 42 mΩ RDS(ON) at VGS = -10V, and -5.4A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power-management functions including backlighting and DC-DC converters.
For engineers reviewing the DMP3045LVTQ datasheet, DMP3045LVTQ pinout, DMP3045LVTQ application, or DMP3045LVTQ equivalent, key selection criteria include its low on-resistance at -4.5V gate drive, fast switching speed (tF = 26 ns), ESD-protected gate, TSOT26 package thermal performance (RθJA = 104 °C/W), and automotive qualification status.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage of -1 to -2.1 V, enabling robust turn-on control in low-voltage automotive systems. Its body diode supports reverse-current conduction in synchronous rectification and load-switching topologies.
The device features low input capacitance (Ciss = 749 pF) and low gate charge (Qg = 7 nC at VGS = -4.5V), reducing driver losses and improving efficiency in high-frequency DC-DC conversion stages operating up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage in off-state; suitable for 24V automotive rail protection |
| RDS(ON) | 42 mΩ @ VGS = -10V - Low conduction loss at full gate drive; enables <1.2 W dissipation at 5.4A |
| RDS(ON) | 65 mΩ @ VGS = -4.5V - Validated operation from standard 3.3V/5V logic-level controllers |
| Qg | 7 nC @ VGS = -4.5V - Enables fast switching with minimal gate driver power demand |
| Ciss | 749 pF - Limits Miller-induced turn-on risk in high-dV/dt environments |
| TJ Range | -55 to +150 °C - Supports under-hood deployment without derating in most automotive zones |
| PD | 1.2 W - Power handling on FR-4 PCB with minimum pad layout; defines thermal design margin |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3045LVTQ-13 | N-channel counterpart with identical RDS(ON) and package; requires high-side gate driver or bootstrap circuitry | Not suitable for high-side switch without level shift; preferred only where N-channel topology simplifies layout | Select only when existing design uses N-channel biasing and driver ICs are already present |
| IPD25N031L3ATMA1 | Higher RDS(ON) (3.1 mΩ) but TO-252 package; 25A rating; higher thermal mass and cost | Better suited for >10A continuous loads; incompatible with space-constrained TSOT26 footprints | Choose only when board area permits larger package and system requires >10A peak current capability |

FAQ
What is the maximum continuous drain current at +105°C ambient?
At TA = +105°C, the DMP3045LVTQ delivers -2.7A continuous drain current with VGS = -10V, based on thermal derating from its 1.2 W power dissipation limit and 104 °C/W RθJA on standard FR-4 PCB. This value assumes no additional heatsinking and accounts for junction temperature reaching 150°C.
Does this MOSFET require external gate resistors for automotive EMI compliance?
No external gate resistor is required solely for EMI suppression-the device's 749 pF Ciss and 79 pF Crss> inherently limit dv/dt. However, a 10 Ω series gate resistor is recommended to dampen ringing during fast switching in high-inductance PCB layouts, especially in CAN/LIN bus proximity zones.
Can DMP3045LVTQ replace DMP3045LVT in existing designs?
Yes-DMP3045LVTQ is a direct replacement for DMP3045LVT, sharing identical electrical specifications, TSOT26 package dimensions, and pinout. The "Q" suffix denotes AEC-Q101 qualification and PPAP capability; no layout or firmware changes are needed for drop-in upgrade in automotive production.
What is the safe operating area (SOA) limitation at 100 μs pulse width?
At 100 μs pulse width and TC = 25°C, the SOA curve supports up to -12A at VDS = -10V. This is limited by RDS(ON) conduction heating rather than avalanche energy, making it suitable for short-circuit protection response in automotive fusing circuits.
