Product details
Overview
DMG7702SFG-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET with monolithically integrated Schottky diode in PowerDI®3333-8 package, delivering 7.3 mΩ RDS(on) at VGS = 10V, 13.5A ID, and 4.3 nC Qrr, optimized for high-efficiency DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMG7702SFG-7 datasheet, DMG7702SFG-7 pinout, DMG7702SFG-7 application, or DMG7702SFG-7 equivalent, key selection criteria include its low 0.45V VSD, 1296 pF Ciss, AEC-Q101 qualification, thermally efficient 33% board-area reduction versus SO-8, and gate charge profile enabling high-frequency synchronous rectification.
Technical Context
This DIOFET integrates a MOSFET and Schottky diode on a single die using a patented process, eliminating body diode conduction losses and reducing reverse recovery charge by replacing the parasitic PN junction with a low-VF Schottky. Its gate threshold voltage (1.0–2.5 V) supports 3.3V/5V logic-level drive.
The device operates across –55°C to +150°C, with RθJA of 58°C/W under 1-inch² copper and 145°C/W on standard FR-4, enabling compact thermal design in space-constrained power management modules where pulsed drain current up to 90A must be sustained without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12V input rail applications with 2× safety margin |
| RDS(on) | 7.3 mΩ @ VGS = 10V - Enables <1W conduction loss at 12A continuous load |
| VSD | 0.45 V typical - Reduces forward drop and heat generation during freewheeling vs. standard MOSFET body diode |
| Qrr | 4.3 nC - Minimizes switching loss and EMI during hard-commutation in synchronous buck topologies |
| Ciss | 1296 pF - Supports stable gate drive with standard 1Ω–3Ω external resistors at 500 kHz–1 MHz switching |
| ID (continuous) | 12 A @ TA = 25°C - Sustains full-load operation in 20W–30W DC-DC stages with minimal heatsinking |
| TJ max | +150°C - Allows operation in automotive cabin or industrial ambient environments without derating |
Pinout & Package
Package: PowerDI®3333-8 - 3.3 mm × 3.3 mm × 0.8 mm surface-mount package with exposed drain paddle for enhanced thermal dissipation; occupies only 33% board area of SO-8 while supporting 2.2 W steady-state power dissipation on 1-inch² copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source | Common source connection for all three internal MOSFET cells; tied to PCB ground plane for lowest inductance return path |
| 5, 6, 7, 8 | Drain | Parallel-connected drain terminals feeding output node; electrically tied to exposed paddle for thermal and electrical conduction |
| Pin 1 (top view marker) | Gate | Single gate input controlling all parallel cells; requires ≤3Ω series resistance to prevent oscillation at >1 MHz |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic MOSFET + Schottky integration | Eliminates discrete diode placement and layout parasitics, reducing BOM count and board area in buck converter high-side switches |

FAQ
Is DMG7702SFG-7 pin-compatible with SO-8 MOSFETs?
No. DMG7702SFG-7 uses the PowerDI®3333-8 package with an 8-pin dual-row layout (4-source, 4-drain, 1-gate), differing from SO-8's gull-wing leadframe. Its pin 1 is marked on top view, and the exposed drain paddle requires dedicated thermal pad routing-not a direct SO-8 drop-in replacement.
What is the maximum safe operating frequency for DMG7702SFG-7 in a synchronous buck converter?
Based on its 15.8 ns turn-on delay, 27.8 ns rise time, and 29.7 ns turn-off delay, DMG7702SFG-7 supports stable operation up to 1.2 MHz in well-designed gate-drive circuits with ≤3Ω series resistance and proper PCB layout-verified by Diodes' application note AP02011 for DIOFETs.
Does DMG7702SFG-7 require a gate resistor for EMI suppression?
Yes. A 1.5Ω–3Ω gate resistor is recommended to dampen ringing caused by its 1296 pF Ciss and low 0.26Ω intrinsic gate resistance. This controls dV/dt during switching, reduces radiated emissions, and prevents false triggering in high-noise industrial environments per test data in Figure 14 of DS35248 Rev. 7-3.
Can DMG7702SFG-7 be used in linear regulator applications?
No. Its RDS(on) is optimized for switching operation, and its Safe Operating Area (SOA) limits continuous linear-mode power dissipation to 0.89W on FR-4 (Figure 1). For linear regulation, discrete MOSFETs with wider SOA curves and higher PD ratings are required.
