Product details
Overview
DMC3025LDV-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single PowerDI3333-8 (Type UXC) package, integrating an N-channel (30V, 25mΩ @ 10V) and P-channel (-30V, 25mΩ @ -10V) device for half-bridge or level-shifting power management. It delivers 15A/–15A continuous drain current at TC = +25°C with low gate charge (9.8nC/19.7nC), fast switching (tD(ON) = 3.9ns/3.7ns), and low input capacitance (500pF/1188pF), enabling high-efficiency synchronous buck converters and motor drivers.
For engineers reviewing the DMC3025LDV-7 datasheet, DMC3025LDV-7 pinout, DMC3025LDV-7 application, or DMC3025LDV-7 equivalent, key selection criteria include complementary RDS(ON) matching at 4.5V/–4.5V, thermal resistance (RθJC = 15°C/W), avalanche energy ratings (9.8mJ/24mJ), and PowerDI3333-8 footprint compatibility with space-constrained DC-DC modules.
Technical Context
This dual MOSFET implements a matched complementary topology optimized for bidirectional control and synchronous rectification. The N-channel device features VGS(TH) = 1.0–2.0V and RDS(ON) = 25mΩ @ 10V/35mΩ @ 4.5V; the P-channel counterpart has VGS(TH) = –1.2 to –2.4V and RDS(ON) = 25mΩ @ –10V/38mΩ @ –4.5V - enabling robust gate drive across standard logic-level interfaces.
Thermal design leverages a low RθJC of 15°C/W to the exposed drain pad, supported by FR-4 PCB layouts with 2oz copper thermal bias. Dynamic performance is characterized by asymmetric gate charge (Qg = 9.8nC vs. 19.7nC) and reverse recovery metrics (tRR = 5.6ns/10.4ns), reflecting tailored channel engineering for reduced shoot-through risk in bridge configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LSD-7 | Lower voltage (20V), lower RDS(ON) (12mΩ), smaller PowerDI3333-8 footprint but no avalanche rating | Better suited for 5V/12V logic-level POLs; unsuitable for 24V industrial transients | Select when operating below 18V and avalanche immunity is not required |
| SI6926ADQ-T1-GE3 | Higher RDS(ON) (32mΩ/42mΩ @ 4.5V), larger SO-8 package, higher Ciss (720pF/1400pF) | Compatible with legacy SO-8 layouts but requires 30% larger board area and higher gate drive power | Select only for drop-in replacement in existing SO-8 designs where thermal performance is secondary |
Compared with DMC3025LDV-7, DMC2038LSD-7 trades voltage headroom for lower conduction loss in low-voltage apps, while SI6926ADQ-T1-GE3 sacrifices thermal density and switching speed for package familiarity - making DMC3025LDV-7 optimal for new 24V space-constrained designs demanding avalanche ruggedness.

FAQ
What is the maximum continuous drain current for each channel at TC = +70°C?
The N-channel device supports 12A and the P-channel device supports –12A at TC = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI3333-8 package under sustained power dissipation; actual usable current depends on PCB copper area and ambient temperature.
Does DMC3025LDV-7 support 3.3V logic-level gate drive?
No - the N-channel VGS(TH) min is 1.0V but RDS(ON) rises to 35mΩ at VGS = 4.5V, and the P-channel requires –4.5V for 38mΩ operation. Driving from 3.3V logic results in excessive conduction loss (>100mΩ) and unreliable turn-on; a gate driver with ≥5V output is required.
How is thermal performance affected when both channels operate simultaneously?
Simultaneous operation increases junction temperature due to shared thermal path through the common exposed drain pad. The datasheet specifies RθJC = 15°C/W for each channel independently; combined dissipation requires derating using the transient thermal impedance curve (Figure 25) and duty-cycle-adjusted RθJA values.
Can DMC3025LDV-7 be used in linear regulator applications?
No - it is not characterized or rated for linear mode operation. The Safe Operating Area (SOA) curves (Figures 12 and 24) show limited DC capability (≤1A at VDS = 15V), and the body diode forward voltage (0.7–1.0V) lacks the precision and stability required for pass-element regulation.
