Product details
Overview
DMG5802LFX-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a W-DFN5020-6 package, rated for 24V V(BR)DSS, 15mΩ RDS(ON) at 4.5V VGS, and 6.5A continuous drain current at 25°C. It delivers low conduction loss and fast switching for compact DC-DC converters and power management circuits in space-constrained industrial and consumer systems.
For engineers reviewing the DMG5802LFX-7 datasheet, DMG5802LFX-7 pinout, DMG5802LFX-7 application, or DMG5802LFX-7 equivalent, key selection criteria include its dual-channel layout, 2.5V logic-level gate drive compatibility, 3kV ESD protection, thermal resistance of 126.5°C/W, and AEC-Q101 qualification for reliability-critical designs.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection-each channel operates independently with separate source, gate, and drain terminals. Its 0.8mm height and 2.0×5.0mm footprint enable high-density PCB layouts while maintaining thermal performance via exposed drain pads.
The device uses trench-gate technology to achieve low RDS(ON) down to 11mΩ (typical) at 4.5V VGS and maintains stable threshold voltage (0.6–1.5V) across –55°C to +150°C ambient, supporting robust operation in thermally variable environments without gate drive overdesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 24V - supports input rails up to 20V DC-DC stages with 20% safety margin |
| RDS(ON) | 15mΩ @ 4.5V VGS - enables ≤98mW conduction loss at 6.5A, critical for <1W power stages |
| ID (continuous) | 6.5A @ 25°C - sustains full load in dual-phase buck controllers with FR-4 PCB layout |
| Qg | 14.5nC @ 4.5V - allows efficient 1MHz switching with <1W gate drive power at 5V logic |
| Ciss | 1066pF - determines Miller effect magnitude and gate driver sizing for hard-switched topologies |
| TJ range | –55°C to +150°C - qualified for under-hood automotive and industrial ambient conditions |
| ESD rating | 3kV HBM - eliminates need for external TVS on gate lines in handheld and portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN5011LFG-7 | Single-channel, same W-DFN5020-6 package, 11mΩ RDS(ON) @ 4.5V but no dual configuration | Requires two devices for dual functionality; higher board area and gate drive complexity | Select when discrete channel isolation or staggered timing is required beyond dual integration |
| SI6926ADQ-T1-GE3 | 6-pin SO-8, 22mΩ RDS(ON) @ 4.5V, 5.3A ID, no AEC-Q101 qualification | Larger footprint (5×6mm), higher thermal resistance (130°C/W), unsuitable for automotive under-hood use | Choose for cost-sensitive industrial controls where AEC-Q101 and space constraints are not mandatory |
Compared with DMN5011LFG-7 and SI6926ADQ-T1-GE3, the DMG5802LFX-7 uniquely combines dual-channel integration, AEC-Q101 qualification, and sub-15mΩ RDS(ON) in a 2.0×5.0mm footprint-making it optimal for space- and reliability-constrained dual-switching nodes where board area and thermal budget are primary constraints.

FAQ
What is the maximum safe operating temperature for DMG5802LFX-7?
The DMG5802LFX-7 has a specified junction temperature range of –55°C to +150°C. Its absolute maximum storage temperature is also –55°C to +150°C. When mounted on an FR-4 PCB with minimum recommended pad layout, the device achieves a thermal resistance of 126.5°C/W, allowing sustained operation at 6.5A only if ambient temperature remains ≤75°C or board-level cooling is applied.
Can DMG5802LFX-7 be used in a synchronous buck converter's high-side position?
Yes-DMG5802LFX-7 supports high-side switching when driven by a bootstrap gate driver capable of delivering ≥4.5V above the source potential. Its 12V maximum gate-source voltage rating and 15mΩ RDS(ON) at 4.5V VGS make it suitable for high-side roles in 12V-input buck converters operating up to 500kHz, provided dead-time control prevents shoot-through.
Does DMG5802LFX-7 have integrated body diodes, and what is their forward voltage?
Yes-each channel includes a monolithic body diode with typical forward voltage of 0.6V at 1A source current and 25°C ambient. This diode enables freewheeling in buck and flyback topologies and supports reverse-current protection in load-switch configurations without external components.
Is the W-DFN5020-6 package lead-free and RoHS compliant?
Yes-the DMG5802LFX-7 is fully lead-free and RoHS 2 (2011/65/EU) compliant, with no intentionally added lead, halogen, or antimony. Its molding compound meets UL 94V-0 flammability rating and contains <900ppm bromine, <900ppm chlorine, and <1000ppm antimony, satisfying JEDEC JS709B "Green" definitions.
