Product details
Overview
DMG7702SFG-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET monolithically integrated with a Schottky diode in a PowerDI3333-8 package, delivering 7.3 mΩ RDS(on) at VGS = 10V, 13.5A drain current, and 0.45V forward diode voltage. It serves as a high-efficiency synchronous rectifier or power switch in DC-DC converters.
For engineers reviewing the DMG7702SFG-13 datasheet, DMG7702SFG-13 pinout, DMG7702SFG-13 application, or DMG7702SFG-13 equivalent, key selection criteria include its integrated Schottky's low Qrr (4.3 nC), low VSD, gate charge profile (Qg = 31.6 nC @ 10V), thermal resistance (RθJA = 58 °C/W with 1-inch copper), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This DIOFET combines a trench-gate MOSFET and Schottky diode on a single die to eliminate body diode conduction losses and reduce reverse recovery energy. Its low Qgd/Qg ratio (5.0/31.6 ≈ 16%) minimizes risk of shoot-through during high-frequency switching.
The device operates across –55°C to +150°C junction temperature, supports ±20V gate drive, and achieves 10mΩ RDS(on) at 10V while maintaining 15mΩ at 4.5V - enabling robust operation in 3.3V and 5V control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage compatible with 24V rail and 12V automotive systems. |
| RDS(on) | 7.3 mΩ @ VGS = 10V, ID = 13.5A - Enables <1W conduction loss at 12A continuous current. |
| VSD | 0.45 V @ IS = 1A - Integrated Schottky reduces forward drop by ~0.25V vs. standard body diode, cutting diode conduction loss. |
| Qrr | 4.3 nC - Low reverse recovery charge minimizes switching loss and EMI in hard-switched topologies. |
| RθJA | 58 °C/W (with 1″² copper) - Enables 2.2W steady-state dissipation at +70°C ambient without forced cooling. |
| ID (max) | 16.0 A (pulsed, t<10s) - Supports peak load handling in transient conditions like motor startup or inrush limiting. |
| AEC-Q101 | Qualified - Validated for automotive applications including infotainment power supplies and LED driver modules. |
Pinout & Package
Package: PowerDI3333-8 - thermally enhanced 8-pin surface-mount package with exposed drain pad; footprint occupies only 33% of SO-8 area and delivers 11 °C/W junction-to-case thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source | Common source terminals tied internally; low-inductance parallel connection improves current sharing and thermal spreading. |
| 5, 6, 7, 8 | Drain | Exposed drain pad + four top-side drain pins - optimized for high-current paths and PCB heat sinking via thermal pad. |
| Pin 1 (marked) | Gate | Single gate input; low gate resistance (Rg = 1.6 Ω typical) enables fast turn-on with minimal external gate resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic DIOFET integration | Eliminates discrete Schottky placement error and parasitic inductance, ensuring precise timing alignment between MOSFET and diode switching. |
| Low Qgd/Qg ratio | 15.8% (5.0/31.6 nC) - reduces Miller plateau duration and improves immunity to dv/dt-induced false turn-on in high-side configurations. |
| Thermally efficient layout | 0.072 g mass and 58 °C/W RθJA enable compact, fanless designs in space-constrained backlighting and portable power modules. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, HTRB, and UHAST - suitable for under-hood and cabin electronics without derating. |

FAQ
Is DMG7702SFG-13 recommended for new designs?
No - Diodes Incorporated explicitly marks DMG7702SFG as "NOT RECOMMENDED FOR NEW DESIGN" in its official datasheet (Rev. 7-3, August 2018). This designation indicates the part is in mature phase with no roadmap for future revisions or long-term availability guarantees. Existing designs may continue using it, but new projects should select qualified alternatives.
What is the thermal pad connection requirement for PowerDI3333-8?
The exposed drain pad (pins 5–8) must be soldered to a minimum 1-inch² copper pour on the PCB for rated 2.2W power dissipation. The datasheet specifies this layout uses 2 oz copper and defines RθJA = 58 °C/W under those conditions. Omitting the thermal pad increases RθJA to 145 °C/W, limiting usable power to 0.89W.
Does DMG7702SFG-13 integrate a Schottky diode in antiparallel or series configuration?
The integrated Schottky diode is connected in antiparallel (source-to-drain) with the MOSFET channel, functioning as a low-loss freewheeling path during discontinuous conduction mode. This configuration replaces the intrinsic body diode, delivering VSD = 0.45V instead of ~1.2V, confirmed by Figure 11 and the "DIOFET" process description in the datasheet.
Can DMG7702SFG-13 operate reliably at 150°C junction temperature?
Yes - the device is rated for TJ = –55°C to +150°C and tested per AEC-Q101. Figure 8 shows normalized RDS(on) remains ≤1.6× nominal at 150°C, and Figure 10 confirms VGS(th) stays within 1.0–2.5V across that range. Derating is required: at TA = +70°C, maximum continuous ID drops to 9.5A (VGS = 10V) to maintain TJ ≤ 150°C.
