Product details
Overview
DMP3098LSD from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -30V V(BR)DSS, 65mΩ RDS(on) at VGS = -10V, and -4.4A continuous drain current at TA = +25°C. It serves as a compact, high-efficiency load or analog switch in space-constrained DC-DC and power management circuits.
For engineers reviewing the DMP3098LSD datasheet, DMP3098LSD pinout, DMP3098LSD application, or DMP3098LSD equivalent, key selection criteria include its dual-channel P-channel topology, low gate threshold (–1.0 to –2.1V), fast switching (td(on) = 6.0ns), low Ciss (336pF), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent P-channel MOSFETs sharing no internal connection-each with separate source, drain, and gate terminals. Its enhancement-mode operation requires negative gate-source voltage for conduction, and it features body diodes with VSD = –0.5 to –1.2V at IS = –2.6A.
The SO-8 package supports dual-channel layout with symmetrical thermal resistance (RθJA = 70°C/W on 1"×1" 2 oz Cu), and its low Qg (4.0–7.8nC) enables efficient gate drive in high-frequency switching applications up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | –30V - Maximum blocking voltage before avalanche conduction in each channel |
| RDS(on) max | 65mΩ @ VGS = –10V - Ensures ≤330mW conduction loss at –5A per channel |
| ID (continuous) | –4.4A @ TA = +25°C - Supports sustained load switching up to ~15W per channel with proper PCB copper |
| VGS(th) | –1.0 to –2.1V - Enables logic-level compatibility with 3.3V microcontroller GPIO when used with level-shifting or pull-up networks |
| Ciss | 336pF - Limits gate drive power and influences switching speed in PWM control loops |
| Qg | 4.0–7.8nC - Determines minimum gate driver current requirement for <100ns turn-on in synchronous buck topologies |
| PD | 1.8W - Specifies maximum steady-state power dissipation on standard FR-4 PCB without heatsink |
Pinout & Package
Package: SO-8, surface-mount, lead-free, RoHS-compliant molded plastic case (UL 94V-0). Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D1) | Drain of Channel 1 | Main current sink node for first MOSFET; connected to high-side rail in high-side switch configuration |
| 2 (S1) | Source of Channel 1 | Reference node for Channel 1; ties to load or ground depending on switch topology |
| 3 (G1) | Gate of Channel 1 | Control input requiring negative bias relative to S1 to turn on; isolated from other channel |
| 4 (S2) | Source of Channel 2 | Independent reference node for second MOSFET; not internally tied to S1 |
| 5 (D2) | Drain of Channel 2 | Second independent current sink; usable for dual-rail or redundant load control |
| 6 (G2) | Gate of Channel 2 | Separate control input; allows asynchronous or complementary switching of two loads |
| 7, 8 (NC) | No Connect | Not internally bonded; left floating or grounded per layout best practice to reduce noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent P-channel structure | Enables two separate high-side switches in one SO-8 footprint, reducing board area vs. discrete solutions |
| Low RDS(on) at –4.5V VGS | 115mΩ ensures <500mW loss at –3.2A, supporting 3.3V logic-driven power gating |
| AEC-Q101 qualified | Validated for automotive ambient temperature range (–55°C to +150°C) and mechanical stress requirements |
| Low Ciss and Crss | 336pF/49pF minimizes Miller effect, enabling stable 500kHz+ PWM operation with standard gate drivers |
| Halogen- and antimony-free "Green" construction | Meets IEC 61249-2-21:2010 with Br+Cl <1500ppm and Sb <1000ppm for eco-sensitive industrial deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LSD-7 | RDS(on) = 75mΩ @ –10V; higher Qg (9.5nC); same SO-8 footprint | Slightly lower efficiency at high frequency due to increased switching loss | Preferred where cost sensitivity outweighs 5% conduction loss penalty |
| SI3483DV-T1-GE3 | Single-channel only; RDS(on) = 50mΩ @ –4.5V; different pinout (no G2/S2/D2 mapping) | Requires two devices and additional routing for dual-load use | Chosen when design already uses Vishay's ecosystem and needs tighter RDS(on) tolerance |
Compared with DMC2038LSD-7 and SI3483DV-T1-GE3, the DMP3098LSD uniquely delivers dual-channel integration with AEC-Q101 qualification and balanced trade-offs between gate drive simplicity, conduction loss, and thermal performance in SO-8.

FAQ
What is the maximum safe operating junction temperature for DMP3098LSD?
The absolute maximum junction temperature is +150°C, and the device is characterized across –55°C to +150°C ambient. Thermal derating begins at TJ > 125°C, where RDS(on) increases by ~0.5%/°C above 25°C, requiring PCB copper area ≥1"×1" 2 oz for full-rated current at elevated ambient temperatures.
Can DMP3098LSD be used in a synchronous rectifier configuration?
No - DMP3098LSD is a P-channel enhancement-mode MOSFET optimized for high-side switching, not synchronous rectification. Its body diode forward voltage (–0.5 to –1.2V) and lack of integrated gate driver timing control make it unsuitable for flyback or LLC secondary-side rectification where low VSD and precise gate timing are required.
Is the SO-8 package thermally enhanced or standard outline?
It uses the standard SO-8 outline (JEDEC MS-012) with no exposed pad or thermal tab. Thermal performance relies entirely on PCB copper area: RθJA = 70°C/W is measured on 1"×1" 2 oz Cu pads on FR-4. For higher power, designers must implement external copper pour or thermal vias - no internal thermal enhancement is present.
Does DMP3098LSD support 1.8V logic-level gate drive?
No - its gate threshold voltage range is –1.0V to –2.1V, and RDS(on) rises sharply below –2.5V VGS. At 1.8V drive (i.e., VGS ≈ –1.8V), RDS(on) exceeds 250mΩ, causing >1.2W loss at –3A. A minimum –3.3V gate drive is recommended for reliable operation with acceptable conduction loss.
