Product details
Overview
DMC6040SSD from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SO-8 package, integrating an N-channel (60V, 40mΩ @ 10V) and P-channel (-60V, 110mΩ @ -10V) device for half-bridge or dual-switching power stages. It delivers 6.5A/–3.9A continuous drain current at +25°C and supports high-efficiency DC-DC converters and backlight power management.
For engineers reviewing the DMC6040SSD datasheet, DMC6040SSD pinout, DMC6040SSD application, or DMC6040SSD equivalent, this dual-MOSFET solution enables compact synchronous rectification, bidirectional load switching, and space-constrained power-management designs requiring matched thermal and electrical characteristics across both channels.
Technical Context
This device implements two discrete enhancement-mode MOSFETs-Q1 (N-channel) and Q2 (P-channel)-in one monolithic SO-8 package with electrically isolated dies. Each channel features independent gate control, defined threshold voltages (1–3V for Q1, –1 to –3V for Q2), and body diodes rated for 2.1A/–2.1A forward conduction.
The structure supports complementary switching in buck-boost, H-bridge, and OR-ing configurations. Its low RDS(ON) values (33mΩ/86mΩ typical at VGS = ±10V), fast switching times (tD(on) = 3.6ns/3.7ns), and matched thermal resistance (RθJA = 80°C/W) ensure balanced dynamic performance and thermal coupling under shared PCB layout conditions.
Key Specifications

|---|---|
|
Use Scenario: Synchronous rectification in 12V-to-5V/3.3V step-down converters for industrial HMIs and embedded controllers. IC Role / Device Role / Timing Role: Q1 acts as high-side main switch; Q2 serves as low-side synchronous rectifier, replacing Schottky diode to reduce conduction loss. Use Value: Achieves >92% efficiency at 3A load due to combined RDS(ON) of 119mΩ and fast trr-controlled commutation. |
Use Scenario: Constant-current LED string control in automotive instrument clusters and display backlighting. IC Role / Device Role / Timing Role: Q1 controls PWM dimming via high-side switching; Q2 provides reverse-polarity protection and current sink path during off-cycle. Use Value: Enables precise 0–100% dimming with <1% current ripple using matched gate timing and low Ciss-driven slew rates. |
| Load Switching | H-Bridge Motor Control |
|
Use Scenario: Dual-rail power sequencing in FPGA or SoC power domains requiring independent 5V and –5V supply enable. IC Role / Device Role / Timing Role: Q1 switches positive rail; Q2 switches negative rail; both controlled by independent logic-level signals. Use Value: Eliminates need for separate level-shifters or P-channel-only solutions, simplifying control logic and reducing BOM count. |
Use Scenario: Bidirectional 24V brushed DC motor control in smart actuators and HVAC dampers. IC Role / Device Role / Timing Role: Q1/Q2 form one half-bridge leg; paired with external N/P pair for full H-bridge; body diodes handle freewheeling current. Use Value: Supports 3.9A peak motor current with <0.5V saturation drop per channel, minimizing heat generation in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC6040SSDQ | Automotive-grade variant qualified to AEC-Q101; identical electrical specs but with extended temperature screening and traceability. | Required for automotive ECUs and ADAS modules where PPAP documentation and lot-level traceability are mandatory. | Select DMC6040SSDQ only when automotive qualification is contractually required; otherwise DMC6040SSD offers same performance at lower cost. |
| SI6926ADQ-T1-GE3 | Higher RDS(ON) (50mΩ/130mΩ), larger Qg (24nC/22nC), and SO-8 package with different pinout (G1/D1/S1/G2/D2/S2). | Not pin-compatible; requires PCB redesign; suitable only when higher thermal margin or legacy design reuse is prioritized over efficiency. | Use only if existing layout accommodates SI6926ADQ pin mapping; avoid for new designs targeting <1.2W total loss or <15ns trr-critical timing. |
Compared with DMC6040SSD, DMC6040SSDQ adds automotive qualification without altering electrical behavior, while SI6926ADQ-T1-GE3 trades efficiency and timing precision for broader legacy compatibility-making DMC6040SSD optimal for cost-sensitive, space-constrained industrial power stages.

FAQ
What is the maximum safe operating voltage for each channel of the DMC6040SSD?
The N-channel (Q1) has a guaranteed drain-source breakdown voltage (BVDSS) of 60V, and the P-channel (Q2) is rated for –60V. These values represent the absolute maximum DC blocking capability before avalanche conduction begins. Operation above ±60V-even briefly-risks irreversible damage. Derating to ±50V is recommended for reliable long-term use under transient conditions.
Can the DMC6040SSD be used in a synchronous buck converter without external gate drivers?
Yes, but only at moderate switching frequencies (<500kHz) and low load currents (<2A). The device's Qg values (20.8nC/19.4nC) require ~20mA average gate current at 1MHz; microcontroller GPIOs lack sufficient drive strength. For full-rated 6.5A/–3.9A operation, a dedicated gate driver (e.g., TC4427) is required to achieve clean turn-on/turn-off and prevent shoot-through.
How does the thermal performance of the DMC6040SSD compare between its two channels?
Both channels share identical thermal resistance (RθJA = 80°C/W on FR-4 with minimum pads) and junction-to-case (RθJC = 14.7°C/W), meaning they dissipate heat at equal rates under matched electrical loading. However, the P-channel (Q2) exhibits higher RDS(ON), resulting in ~2.6× greater conduction loss than Q1 at equal current-so Q2 will run hotter in asymmetric duty-cycle applications unless thermally balanced via layout.
Is the DMC6040SSD suitable for automotive applications?
The standard DMC6040SSD is not automotive-qualified. Diodes offers the DMC6040SSDQ variant, which undergoes AEC-Q101 stress testing and includes full PPAP documentation. While the base part meets JEDEC reliability standards and operates across –55°C to +150°C, it lacks the traceability, screening, and failure-rate validation required for safety-critical automotive systems.
