Product details
Overview
DMC3026LSD from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SO-8 package, integrating one N-channel (30V, 25mΩ @ 10V) and one P-channel (-30V, 28mΩ @ -10V) device for half-bridge or synchronous rectifier topologies in DC-DC converters. It delivers 6.5A/–6.2A continuous drain current at 25°C, supports fast switching (tD(off) = 22.3ns / 60.5ns), and is qualified to AEC-Q101 for automotive-grade reliability.
For engineers reviewing the DMC3026LSD datasheet, DMC3026LSD pinout, DMC3026LSD application, or DMC3026LSD equivalent, this dual MOSFET enables compact, high-efficiency power management in space-constrained buck converters, LED backlight drivers, and battery-powered industrial modules where complementary gate drive and matched thermal behavior are critical.
Technical Context
This dual MOSFET implements a monolithic complementary topology with isolated die and shared thermal path in SO-8. The N-channel device features low RDS(on) (19mΩ typ @ 10V) and low Ciss (641pF), while the P-channel exhibits higher Ciss (1241pF) and slower turn-off (tD(off) = 60.5ns), reflecting inherent carrier mobility differences in silicon.
Both devices share identical SO-8 footprint and thermal resistance (RθJA = 78°C/W with 1-inch2 copper), enabling balanced PCB layout and simultaneous thermal management. Gate threshold voltages are symmetric (±1–3V), supporting standard 3.3V/5V logic-level drive without level-shifting.
Key Specifications

| RDS(on) max | 25mΩ @ 10V (N), 28mΩ @ –10V (P): Enables <1.2W conduction loss at 6A in 12V→5V buck stage with 50% duty cycle. |
| ID cont | 6.5A (N), –6.2A (P) at 25°C: Sustains peak load currents in 30W-class point-of-load regulators. |
| Ciss | 641pF (N), 1241pF (P): Low input capacitance reduces gate drive power and improves switching efficiency above 500kHz. |
| Qg | 13.2nC (N @ 10V), 22nC (P @ –10V): Matches gate driver output capability of common integrated controllers like MP2315 or TPS54332. |
| tD(off) | 22.3ns (N), 60.5ns (P): Enables precise dead-time control in synchronous rectification to prevent shoot-through. |
| RθJA | 78°C/W (with 1″² copper): Limits junction rise to ≤78°C at 1.2W dissipation-critical for sealed enclosure thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7852DP-T1-GE3 (Vishay) | Higher RDS(on) (32mΩ/38mΩ), larger SO-8 footprint (5.0×6.2mm), no AEC-Q101 rating. | Targeted at commercial-grade consumer power supplies-not suitable for automotive thermal or reliability requirements. | Select only if AEC-Q101 is not required and board space allows 0.1mm larger outline. |
| DMC2038LVT-7 (Diodes Inc.) | Lower voltage rating (20V), lower RDS(on) (15mΩ/18mΩ), same SO-8 package and AEC-Q101 qualification. | Optimized for 12V-input systems (e.g., USB-PD, PoE); insufficient for 24V industrial or automotive inputs. | Prefer for 5–12V applications where tighter RDS(on) and smaller voltage margin are acceptable. |
Compared with Si7852DP and DMC2038LVT, DMC3026LSD uniquely balances 30V rating, AEC-Q101 compliance, and matched N/P RDS(on) in standard SO-8-making it the only choice for 24V automotive buck converters requiring zero derating at 105°C ambient.

FAQ
What is the maximum operating junction temperature for DMC3026LSD?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Continuous operation at this limit requires thermal design ensuring RθJA ≤ 23°C/W (for 1.2W dissipation), typically achieved using ≥1-inch² 2oz copper with thermal vias under the exposed drain pad.
Can DMC3026LSD be used in a synchronous boost configuration?
Yes-the P-channel device serves as the high-side switch and the N-channel as the synchronous rectifier. Its –30V VDSS and –6.2A ID rating support output voltages up to 28V with 10% margin; gate thresholds (–1V to –3V) allow direct 3.3V MCU control without level shifting.
Is the thermal pad (pins 7–8) electrically isolated?
No-the exposed thermal pad is internally connected to both drain terminals (D1 and D2). It must be soldered to a common PCB copper pour tied to the system power ground plane or input rail, depending on topology, to ensure thermal performance and electrical safety.
Does DMC3026LSD support 1.8V logic-level gate drive?
No-its minimum VGS(th) is ±1V, but RDS(on) is not specified below VGS = ±4.5V. At 1.8V, the N-channel conducts <100mA and the P-channel <–80mA; full-rated current requires ≥4.5V drive per device.
