Product details
Overview
DMHC3025LSDQ-13 from Diodes Incorporated is a 30V complementary enhancement-mode MOSFET H-bridge IC containing two N-channel and two P-channel MOSFETs in a single SO-8 package. It delivers 6.0A N-channel and –4.2A P-channel continuous drain current at VGS = ±10V, with RDS(on) as low as 25mΩ (N) and 50mΩ (P), and is AEC-Q101 qualified for automotive solenoid and DC motor drive applications.
For engineers reviewing the DMHC3025LSDQ-13 datasheet, DMHC3025LSDQ-13 pinout, DMHC3025LSDQ-13 application, or DMHC3025LSDQ-13 equivalent, key selection criteria include bidirectional H-bridge switching capability, SO-8 thermal performance (RθJA = 83°C/W), AEC-Q101 qualification, and gate charge values (Qg = 11.7nC/11.4nC at ±10V) critical for PWM-driven motor control timing.
Technical Context
This H-bridge integrates matched N- and P-channel pairs to enable full four-quadrant control of inductive loads without external bootstrap circuitry. Its dual-channel symmetry supports bidirectional current flow, while low Ciss (590pF/631pF) and fast switching (tD(on) = 11.2ns/7.5ns) reduce switching losses in 20–100 kHz PWM motor drives.
The device operates across –55°C to +150°C junction temperature and features integrated body diodes with Qrr = 12nC (N) and 15.3nC (P), enabling efficient freewheeling in brushed DC motor commutation. Gate threshold voltages (1–2V N, –1 to –2V P) ensure reliable turn-on with standard 3.3V/5V logic-level microcontroller outputs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMHC3025LSD-13 | Same die, non-automotive grade; lacks AEC-Q101 qualification and PPAP documentation | Suitable for industrial or consumer products where automotive reliability is not mandated | Select when cost sensitivity outweighs automotive compliance requirements |
| Si7850DP-T1-GE3 | Single-chip dual-N H-bridge (no integrated P-FETs); requires external high-side driver or charge pump | Used in space-constrained designs where only N-channel topology is acceptable | Choose only if existing system already implements bootstrap gate drive infrastructure |
Compared with DMHC3025LSD-13, the -13 suffix variant adds AEC-Q101 validation and traceable automotive sourcing; versus Si7850DP, it eliminates external gate drive complexity but trades off higher RDS(on) on P-side for full integration.

FAQ
What is the maximum safe operating frequency for PWM switching with DMHC3025LSDQ-13?
The device supports PWM frequencies up to 100 kHz in thermally managed layouts. At 25°C ambient and 1.5W total dissipation, its 11.2ns/7.5ns turn-on delays and 8.7ns/13.5ns fall times allow clean edges; however, above 50 kHz, gate driver strength and PCB layout parasitics become dominant limiting factors-not the MOSFET itself.
Can DMHC3025LSDQ-13 drive a 36V motor?
No. Its absolute maximum VDSS is ±30V, and operation above this risks avalanche breakdown. For 36V systems, a 40V-rated H-bridge such as DMHC4035LSDQ-13 is required-this part's RDS(on) increases to 35mΩ (N) and 65mΩ (P), directly impacting conduction loss at rated current.
Does the SO-8 package require thermal vias for automotive operation?
Yes. With RθJA = 83°C/W on standard FR-4, thermal vias under the exposed pad (Pin 2/8 common source nodes) are essential to achieve the 1.5W rating at TA = 85°C. Diodes' AP02002 recommends ≥6 thermal vias (0.3mm diameter, 0.8mm pitch) connected to internal ground planes.
How does the body diode forward voltage affect freewheeling efficiency?
VSD is 0.70–1.2V (N) and –0.7 to –1.2V (P) at IS = 1.7A. This results in ~1.1W freewheeling loss per diode at peak current, making synchronous rectification (using MOSFET channel conduction instead of body diode) mandatory above 10 kHz to maintain >90% efficiency in motor drive applications.
