Product details
Overview
DMC3028LSDX-13 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in SO-8 package, integrating one 30V/7.2A N-channel and one –30V/–7.6A P-channel MOSFET. It delivers RDS(on) of 27mΩ @ VGS = 10V (Q1) and 25mΩ @ VGS = –10V (Q2), with fast switching (tD(off) = 22.3ns for Q1, 60.5ns for Q2), and is qualified to AEC-Q101 for automotive-grade reliability. It is used in synchronous buck converters for DC-DC power management.
For engineers reviewing the DMC3028LSDX-13 datasheet, DMC3028LSDX-13 pinout, DMC3028LSDX-13 application, or DMC3028LSDX-13 equivalent, key selection criteria include complementary channel pairing, low RDS(on) at 4.5V gate drive, SO-8 thermal performance (RθJA = 85°C/W with copper pad), and AEC-Q101 qualification for automotive power stages.
Technical Context
This dual MOSFET implements a matched N+P channel topology in a single SO-8 footprint, enabling compact half-bridge or synchronous rectifier configurations. Its design emphasizes low gate charge (Qg = 13.2nC for Q1 at 10V, 22nC for Q2 at –10V) and low input capacitance (Ciss = 641pF for Q1, 1241pF for Q2), supporting high-frequency switching up to 1MHz in DC-DC converters.
The device features independent body diodes with VSD = 0.7–1.2V (Q1) and –0.7 to –1.2V (Q2), and operates across –55°C to +150°C junction temperature. Thermal resistance is optimized via exposed copper pad layout: RθJA = 85°C/W (with 1-inch² copper) and RθJC = 14.5°C/W, enabling stable operation under 1.5W continuous dissipation at +25°C ambient.
Key Specifications

| RDS(on) | 27mΩ @ 10V (Q1), 25mΩ @ –10V (Q2): Enables <1.5W conduction loss at 6A load in typical 12V output stage. |
| ID cont. | 7.2A (Q1), –7.6A (Q2) at TA = +25°C: Sustains peak currents in 10A-class synchronous buck phases. |
| Qg | 13.2nC (Q1 @ 10V), 22nC (Q2 @ –10V): Reduces gate drive power and enables >500kHz PWM without excessive driver loss. |
| tD(off) | 22.3ns (Q1), 60.5ns (Q2): Limits shoot-through risk in half-bridge dead-time design. |
| RθJA | 85°C/W (with 1″² copper): Allows ~1.2W continuous power at +70°C ambient before derating. |

|---|---|
|
Use Scenario: Driving 12V solenoids and LED loads in vehicle door modules with reverse-polarity protection and PWM dimming. IC Role / Device Role / Timing Role: Dual-channel power switch: Q1 controls ground return (low-side), Q2 provides reverse-battery protection (high-side P-ch). Use Value: Eliminates need for external Schottky diode and separate high-side driver; AEC-Q101 rating ensures 15-year field reliability. |
Use Scenario: 24V-to-5V synchronous buck converter powering industrial PLC I/O modules. IC Role / Device Role / Timing Role: Integrated half-bridge switch: Q1 as high-side switch, Q2 as synchronous rectifier (replacing catch diode). Use Value: Achieves >94% efficiency at 5A load due to low RDS(on) and matched timing, reducing heatsink size by 40%. |
| Laptop Adapter Secondary Side | LED Backlight Driver |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC3025LSDX-13 | Lower RDS(on): 22mΩ (Q1) / 20mΩ (Q2) @ 10V; higher Qg (15.5nC / 24.8nC); same SO-8 package. | Better conduction efficiency but slower switching; suited for <300kHz applications where thermal headroom is constrained. | Select when priority is minimizing I²R loss over switching loss-e.g., 12V input, 3.3V output point-of-load converters. |
| SI6926ADQ-T1-GE3 | Higher VDSS: ±40V; higher RDS(on): 32mΩ / 30mΩ @ 10V; not AEC-Q101 qualified; different pinout (G1/D1/S1/S2/G2/D2). | Broader voltage margin but no automotive qualification; unsuitable for safety-critical vehicle systems. | Choose only for non-automotive industrial use requiring 40V tolerance-e.g., PoE-powered equipment with transient surges. |
Compared with DMC3028LSDX-13, DMC3025LSDX-13 trades faster switching for lower conduction loss, while SI6926ADQ-T1-GE3 sacrifices automotive compliance and thermal performance for wider voltage capability-making DMC3028LSDX-13 optimal for cost-sensitive, AEC-Q101–required 30V synchronous buck stages.

FAQ
What is the maximum continuous drain current for each channel at +70°C ambient?
At TA = +70°C, the N-channel (Q1) supports 4.1A continuous drain current with VGS = 10V, and the P-channel (Q2) supports –4.3A under the same conditions. These values assume mounting on FR-4 with 1-inch² copper pad per the datasheet's thermal test condition (Note 6).
Can DMC3028LSDX-13 be used in a high-side P-channel switch configuration without a gate driver?
No-it requires a gate driver capable of pulling G2 to ≤ –4.5V relative to S2 for full enhancement. With only 0V/5V logic, Q2 remains partially on (VGS(th) = –1 to –3V), risking excessive RDS(on) and thermal runaway. A dedicated P-ch driver or charge pump is mandatory for reliable high-side operation.
Is the thermal pad (pins 7–8) electrically isolated or internally connected?
The exposed thermal pad is internally connected to both S1 and S2 source terminals-not to drain or gate. It must be soldered to a PCB copper pour tied to the system ground or output rail reference to ensure thermal conduction and electrical integrity; floating the pad degrades RθJA by >30%.
How does the AEC-Q101 qualification differ between DMC3028LSDX-13 and DMC3028LSDXQ?
DMC3028LSDX-13 is the commercial-grade part; its AEC-Q101 qualification is documented in Diodes' internal reliability report (not certified per full AEC-Q101 test plan). DMC3028LSDXQ is the automotive-grade variant-fully tested to AEC-Q101 Rev D, including extended HTOL (1000h at 150°C), and shipped with full PPAP documentation and lot-level traceability.
