Product details
Overview
DMHC4035LSDQ-13 from Diodes Incorporated is a 40V complementary enhancement-mode MOSFET H-bridge IC containing two N-channel and two P-channel MOSFETs in a single SO-8 package. It delivers 4.5A N-channel and –3.7A P-channel continuous drain current at VGS = ±10V, with RDS(ON) of 45mΩ (N) and 65mΩ (P), and is AEC-Q101 qualified for automotive solenoid and DC motor drive applications.
For engineers reviewing the DMHC4035LSDQ-13 datasheet, DMHC4035LSDQ-13 pinout, DMHC4035LSDQ-13 application, or DMHC4035LSDQ-13 equivalent, this device supports bidirectional load control with fast switching (tF = 5.5ns N-ch / 15.3ns P-ch), low gate charge (Qg = 12.5nC N-ch / 11.1nC P-ch), and thermal resistance RθJA = 85°C/W on FR-4 PCB.
Technical Context
This H-bridge integrates matched N- and P-channel pairs to enable full four-quadrant motor control without external level-shifting circuitry. Its dual-channel architecture supports synchronous rectification and regenerative braking via independent gate control of all four switches.
The device uses trench-gate MOSFET technology to achieve low RDS(ON) at 4.5V gate drive, enabling operation from standard 5V logic rails. Body diodes are optimized for low VSD (0.7V N-ch / –0.7V P-ch) and fast reverse recovery (tRR = 6.5ns / 15.5ns), reducing switching losses in PWM-driven loads.
Key Specifications

|---|---|
| VDSS | ±40V - Supports 24V automotive systems with 100% margin against load-dump transients. |
| RDS(ON) (N/P @ 10V) | 45mΩ / 65mΩ - Enables <1.8W conduction loss at 4A N-ch and 3.7A P-ch continuous operation. |
| ID Continuous (TA = 25°C) | 4.5A / –3.7A - Sustains rated motor stall current without derating on standard 2oz copper PCB. |
| Qg Total (N/P @ 10V) | 12.5nC / 11.1nC - Reduces gate driver power demand and enables >100kHz PWM switching efficiency. |
| tRR (N/P) | 6.5ns / 15.5ns - Minimizes shoot-through risk and commutation losses during direction reversal. |
| RθJA | 85°C/W - Allows 1.5W total dissipation with ≤127.5°C junction rise above 25°C ambient on FR-4 board. |
| AEC-Q101 Qualified | Yes - Validated for automotive under-hood temperature cycling (–40°C to +150°C) and mechanical shock. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMHC4035LSD-13 | Same die, non-automotive grade (no AEC-Q101 qualification); identical electrical specs and pinout. | Not suitable for automotive production; acceptable for industrial prototypes or cost-sensitive non-automotive designs. | Select only if AEC-Q101 compliance is not required and PPAP documentation is unnecessary. |
| Si9986EDY-T1-GE3 | Higher RDS(ON) (60mΩ/100mΩ @ 10V), larger SO-8 footprint (5.0×6.0mm vs. 4.9×6.0mm), no AEC-Q101 certification. | Limited to industrial motor control; lacks automotive qualification and tighter thermal resistance (RθJA = 95°C/W). | Use only when Diodes' supply chain constraints exist; verify PCB pad compatibility and thermal margin at full load. |
Compared with DMHC4035LSDQ-13, the DMHC4035LSD-13 offers identical performance at lower cost but forfeits automotive traceability, while Si9986EDY-T1-GE3 trades higher conduction loss and weaker thermal performance for broader distributor availability-neither matches the combined AEC-Q101 reliability, SO-8 compactness, and 45mΩ/65mΩ RDS(ON) benchmark.

FAQ
What is the maximum safe operating junction temperature for DMHC4035LSDQ-13?
The absolute maximum junction temperature is +150°C, with continuous operation supported from –55°C to +150°C. Thermal design must ensure TJ ≤ 150°C under worst-case power dissipation (1.5W) and ambient conditions, using the specified RθJA = 85°C/W on FR-4 with 1-inch² copper pour.
Can DMHC4035LSDQ-13 drive a 24V DC motor directly from a 3.3V microcontroller?
No-gate threshold voltages are 1–3V (N-ch) and –1 to –3V (P-ch), but full enhancement requires ≥4.5V for acceptable RDS(ON). At 3.3V, N-ch RDS(ON) rises to ~70mΩ and P-ch exceeds 150mΩ, causing excessive heating. A level-shifting gate driver or 5V IO supply is required for reliable operation.
Does DMHC4035LSDQ-13 include internal protection features like overtemperature or overcurrent shutdown?
No-the device contains no integrated thermal shutdown, current limiting, or fault reporting circuitry. System-level protection must be implemented externally via current-sense resistors, microcontroller ADC monitoring, and software-controlled gate disable, as specified in Diodes' application guidelines for H-bridge motor control.
How does the SO-8 package's thermal performance compare between DMHC4035LSDQ-13 and discrete MOSFET solutions?
The SO-8 package achieves RθJA = 85°C/W with 1-inch² copper, outperforming typical discrete SO-8 MOSFETs (RθJA ≈ 95–110°C/W) due to optimized internal die placement and shared thermal path. However, discrete solutions with exposed-pad packages (e.g., PowerPAK SO-8) offer lower RθJA (<50°C/W) at the cost of board area and layout complexity.
