Product details
Overview
DMP3050LVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDSS, 50 mΩ RDS(ON) @ VGS = -10V, and -4.5A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities for automotive power management, backlighting, and DC-DC converter applications.
For engineers reviewing the DMP3050LVTQ datasheet, DMP3050LVTQ pinout, DMP3050LVTQ application, or DMP3050LVTQ equivalent, key selection criteria include its low on-resistance at -4.5V gate drive, fast switching (tD(OFF) = 28.4 ns), TSOT26 package thermal performance (RθJA = 78 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This MOSFET operates as a high-side load switch or synchronous rectifier in automotive power rails, leveraging its negative threshold voltage (-1.0 to -2.0 V) and low gate charge (Qg = 10.5 nC @ VGS = -10V) for efficient gate driving in 12V systems. Its body diode exhibits VSD = -0.7 V @ IS = -1A, supporting bidirectional current handling in buck converters.
The device's dynamic characteristics-Ciss = 620 pF, Coss = 83 pF, and Crss = 62 pF at VDS = -15V-are optimized for reduced switching losses in high-frequency DC-DC topologies. Thermal design is enabled by its RθJC = 13 °C/W and validated SOA up to 10s pulses at TJ = 150°C on FR-4 with 1-inch² copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage for 12V automotive rail protection and reverse-polarity circuits. |
| RDS(ON) | 50 mΩ @ VGS = -10V - Enables <150 mW conduction loss at 1.7A, suitable for compact LED backlight drivers. |
| ID Continuous | -4.5 A @ TA = +25°C - Supports sustained load switching in infotainment power domains without forced cooling. |
| Qg | 10.5 nC @ VGS = -10V - Reduces gate driver power demand and enables <30 ns turn-off delay in high-speed PWM control. |
| tD(OFF) | 28.4 ns - Limits dead-time requirements in synchronous buck converters operating above 500 kHz. |
| RθJA | 78 °C/W - Allows 1.6 W dissipation on standard FR-4 PCB with 2 oz copper, eliminating need for thermal vias in space-constrained modules. |
Pinout & Package

| 3 (Drain) | Main current path terminal | High-side connection point for load; bonded to large copper pad for thermal conduction to PCB. |
| 4 (Source) | Redundant source connection | Parallel source bond wire reduces package inductance and improves current sharing in high-di/dt switching. |
| 5 (Drain) | Redundant drain connection | Second drain bond enhances thermal transfer and supports >25A pulsed current capability. |
| 6 (Source) | Third source terminal | Provides additional low-inductance return path for body diode conduction during synchronous rectification. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3006LPSQ-13 | RDS(ON) = 4.5 mΩ @ VGS = -10V; larger PowerDI3333 package (RθJA = 50 °C/W); higher Qg = 22 nC | Better thermal performance but requires larger board area; suited for >5A continuous loads | Select when >3.5A steady-state current or lower junction temperature is required; not drop-in due to footprint mismatch. |
| SI7157DP-T1-GE3 | RDS(ON) = 48 mΩ @ VGS = -10V; SO-8 package; AEC-Q101 qualified; higher Ciss = 1050 pF | Standard SO-8 footprint eases prototyping but increases parasitic inductance vs. TSOT26 | Prefer for legacy board rework or where manual soldering is needed; avoid in >1 MHz switching due to higher input capacitance. |
Compared with DMP3050LVTQ, DMT3006LPSQ-13 delivers lower conduction loss but demands more gate drive energy and board space, while SI7157DP-T1-GE3 offers familiar assembly but compromises high-frequency efficiency and thermal density.

FAQ
What is the maximum gate-source voltage rating for DMP3050LVTQ in automotive applications?
The absolute maximum VGS is ±25 V per datasheet, but AEC-Q101 qualification restricts operational use to ±20 V. Exceeding ±20 V risks gate oxide degradation under automotive transient conditions like load dump or jump-start events, even if within the absolute maximum rating.
Can DMP3050LVTQ be used as a synchronous rectifier in a 1 MHz buck converter?
Yes-its tF = 12.4 ns, Coss = 83 pF, and Qgd = 1.9 nC enable reliable operation up to 2 MHz. However, gate drive must deliver ≥±2A peak current to achieve full switching speed; insufficient drive causes increased switching loss and thermal stress.
Does DMP3050LVTQ require external gate resistors for EMI control in automotive PCB layouts?
Not inherently-the integrated 10.8 Ω gate resistance provides moderate damping. For CAN/LIN bus proximity or EMC-critical zones, a 5–10 Ω series resistor is recommended to suppress 100–500 MHz ringing without compromising tD(OFF) beyond 35 ns.
How does the TSOT26 package affect thermal performance compared to SO-8 in automotive under-hood applications?
TSOT26 achieves lower RθJA (78 °C/W vs. ~110 °C/W for SO-8 on same PCB) due to shorter thermal path and exposed drain pad. At 1.2W dissipation, junction temperature rises 94°C above ambient in TSOT26 versus 132°C in SO-8-critical for under-hood operation near 105°C ambient.
