Product details
Overview
DMP3098LSS-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOP-8L package, rated for -30 V VDSS, -5.3 A continuous drain current at 25°C, and 65 mΩ RDS(on) at VGS = -10 V. It serves as a high-efficiency load switch or reverse-polarity protection device in automotive body control modules and industrial power supplies.
For engineers reviewing the DMP3098LSS-13 datasheet, DMP3098LSS-13 pinout, DMP3098LSS-13 application, or DMP3098LSS-13 equivalent, key selection criteria include verified gate threshold (-1 to -2.1 V), low-input capacitance (336 pF Ciss), AEC-Q101 qualification, and SOP-8L thermal performance (RθJA = 50 °C/W).
Technical Context
This MOSFET operates in enhancement mode with negative gate drive, requiring VGS ≤ -1 V to initiate conduction and fully turning on at VGS = -10 V. Its internal structure integrates a body diode with -0.5 to -1.2 V forward voltage at -2 A, enabling bidirectional current handling in DC-DC synchronous rectification paths.
The device exhibits fast switching dynamics: 6.0 ns turn-on delay, 5.0 ns rise time, and 9.5 ns fall time under defined test conditions (VDS = -15 V, ID = -1 A, RG = 6.0 Ω). Gate charge values (QG = 7.8 nC at -10 V) confirm suitability for medium-frequency PWM control up to ~500 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage before avalanche breakdown in reverse-biased drain-source path |
| RDS(on) | 65 mΩ @ VGS = -10 V - On-resistance determines conduction loss and junction temperature rise under 5.3 A load |
| ID (continuous) | -5.3 A @ TA = 25°C - Continuous safe operating current with 2 oz. copper PCB heatsinking |
| Ciss | 336 pF - Input capacitance governs gate drive energy requirement and switching speed limit |

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) = 45 mΩ @ -4.5 V; smaller SOT-23-6 package; lower ID = -4 A | Better suited for space-constrained, lower-current (<3 A) portable electronics | Select when board area is critical and thermal budget permits higher RDS(on) at elevated ambient temperatures |
| SI3457DV-T1-GE3 | RDS(on) = 80 mΩ @ -4.5 V; same SOP-8L footprint; higher VGS(th) (-0.4 to -1.2 V) | More sensitive to gate drive noise due to lower threshold; less stable at marginal VGS | Prefer only if existing layout uses identical footprint and gate drive reliably exceeds -4.5 V |
Compared with DMG3415L-7 and SI3457DV-T1-GE3, DMP3098LSS-13 delivers balanced performance: higher current rating than DMG3415L-7, tighter VGS(th) tolerance than SI3457DV-T1-GE3, and AEC-Q101 validation not offered by either alternative.

FAQ
What is the maximum pulsed drain current rating for DMP3098LSS-13?
The pulsed drain current (IDM) is -20 A, specified under conditions of pulse width ≤10 μs and duty cycle ≤1%. This rating applies only for short-duration transients and must be derated based on ambient temperature and PCB thermal design to avoid exceeding the 150 °C maximum junction temperature.
Does DMP3098LSS-13 require a gate resistor for safe operation?
A gate resistor is recommended to dampen ringing and control slew rate-typical values range from 10 Ω to 100 Ω depending on driver strength and layout parasitics. The datasheet specifies switching times using RG = 6.0 Ω, confirming that external gate resistance improves EMI performance and reduces risk of oscillation during fast transitions.
Can DMP3098LSS-13 be used in synchronous rectification topologies?
Yes-the integrated body diode has a forward voltage of -0.5 to -1.2 V at -2 A and exhibits low reverse recovery charge, making it suitable for low-frequency synchronous rectification in flyback or buck converters where gate drive timing accommodates diode conduction during dead time.
Is the SOP-8L package thermally enhanced compared to standard SO-8?
Yes-the SOP-8L variant features an exposed drain pad (pins 5–8) soldered directly to PCB copper, reducing thermal resistance by ~30% versus standard SO-8. When mounted on 2 oz. copper pads per datasheet test condition, RθJA is 50 °C/W, enabling 2.5 W power dissipation at 70 °C ambient without forced airflow.
