Product details
Overview
DMP3037LSSQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET qualified to AEC-Q101 for automotive use, featuring -30V VDSS, 32mΩ RDS(ON) @ VGS = -10V, and -5.8A continuous drain current at +25°C; it serves as a high-reliability power switch in DC-DC converters and backlighting circuits.
For engineers reviewing the DMP3037LSSQ-13 datasheet, DMP3037LSSQ-13 pinout, DMP3037LSSQ-13 application, or DMP3037LSSQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, SO-8 package thermal performance (RθJA = 77°C/W with 2oz copper), low gate charge (Qg = 17.3nC @ VGS = -10V), and robust UIS capability (EAS = 15mJ).
Technical Context
This MOSFET employs a trench-gate structure optimized for low RDS(ON) and fast switching in high-side configurations. Its gate threshold voltage range (-1.0V to -2.4V) ensures stable turn-on under automotive supply variations, while the integrated body diode supports synchronous rectification and flyback energy recovery.
The device is characterized for operation across -55°C to +150°C junction temperature, with RDS(ON) increasing only 1.6× from 25°C to 150°C at VGS = -10V. Its Ciss (969pF), Coss (138pF), and Crss (102pF) values are specified at VDS = -15V, enabling accurate snubber and gate-drive design in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum blocking voltage in high-side switch configuration without avalanche breakdown |
| RDS(ON) | 32mΩ @ VGS = -10V - Enables ≤185mW conduction loss at -5.8A, critical for thermally constrained automotive modules |
| Qg | 17.3nC @ VGS = -10V - Determines gate driver current requirement (e.g., 1.73mA avg for 1MHz switching) |
| EAS | 15mJ - Confirmed 100% production-tested unclamped inductive switching margin for load dump survival |
| RθJA | 77°C/W - Measured on 2oz FR-4 board with thermal bias; defines maximum power dissipation before thermal shutdown |
| tF | 20ns - Fast fall time enables <100ns total switching transitions, reducing switching losses in 500kHz+ DC-DC stages |
| IAS | -17A - Avalanche current rating supporting transient overcurrent events without failure |

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 |
|---|---|---|---|
| DMT3007LPSQ-13 | Lower RDS(ON) (22mΩ @ -10V) but higher Qg (24nC); same SO-8 package and AEC-Q101 grade | Better conduction efficiency in <300kHz designs; less suitable for >1MHz due to increased gate drive loss | Select when thermal budget is tighter than switching frequency constraints |
| IPD250N03LG | Higher VDSS (-40V), lower RDS(ON) (25mΩ @ -10V), but no 100% UIS test; TO-252 package | Requires PCB redesign for thermal pad; lacks production-screened avalanche robustness for safety-critical loads | Choose only if higher voltage margin is mandatory and UIS testing is handled at system level |
Compared with DMT3007LPSQ-13 and IPD250N03LG, the DMP3037LSSQ-13 delivers optimal balance of gate drive simplicity (low Qg), proven avalanche ruggedness, and SO-8 manufacturability-making it preferred for cost-sensitive, high-volume automotive power switches where reliability validation is non-negotiable.

FAQ
Is DMP3037LSSQ-13 suitable for high-side switching in 24V automotive systems?
Yes. With -30V VDSS and AEC-Q101 qualification, it supports nominal 24V systems including load dump transients up to ISO 7637-2 Pulse 5a (−120V/100ms). Its RDS(ON) remains stable across −40°C to +125°C ambient, ensuring consistent performance in under-hood environments.
What is the maximum continuous drain current at +105°C ambient?
At TA = +105°C with 2oz copper board (Note 6), the derated continuous drain current is −3.2A. This is calculated from PD = 1.0W and RDS(ON) ≈ 38mΩ at 105°C, yielding ID = √(PD/RDS(ON)) ≈ 5.1A, then further limited by package thermal resistance and board layout.
Does DMP3037LSSQ-13 require a gate resistor for stability?
Yes. A 10Ω to 22Ω series gate resistor is recommended to suppress oscillation caused by gate-drain capacitance (Crss = 102pF) interacting with PCB trace inductance. Without it, ringing exceeding ±30V can occur during 10ns rise/fall edges, risking gate oxide damage.
Can this MOSFET replace N-channel devices in existing designs?
No. As a P-channel device, it operates with inverted logic: gate driven negative relative to source. Replacing an N-channel high-side switch requires inverting the gate drive signal and verifying voltage headroom, since VGS must reach −10V for optimal RDS(ON), not +10V.
