Product details
Overview
DMS3012SFG-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET monolithically integrated with a Schottky diode in a single PowerDI3333-8 die, delivering 7.3 mΩ RDS(ON) @ VGS = 10V, 12 A continuous drain current at +25°C, and 4.3 nC Qrr, optimized for high-frequency DC-DC converter power stages.
For engineers reviewing the DMS3012SFG-13 datasheet, DMS3012SFG-13 pinout, DMS3012SFG-13 application, or DMS3012SFG-13 equivalent, key selection criteria include its integrated Schottky's low VSD (0.45 V), low gate charge ratio (Qgd/Qg ≈ 16%), 100% UIS rating, and thermally efficient 3333-8 footprint occupying only 33% board area vs. SO-8.
Technical Context
This DIOFET device uses a patented monolithic process to co-integrate an N-channel MOSFET and Schottky diode on one silicon die, eliminating parasitic body diode conduction losses and enabling fast reverse recovery (trr = 13.1 ns) without external diode placement.
Its gate threshold voltage (VGS(TH) = 1.0–2.5 V) supports 4.5 V logic-level drive, while low input capacitance (Ciss = 1296–4310 pF) and 0.26–2.6 Ω gate resistance enable stable high-frequency switching up to 1 MHz in synchronous buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage in off-state; suitable for 24 V rail and 12 V automotive input systems. |
| RDS(ON) | 7.3 mΩ @ VGS = 10 V - Enables <1.0 W conduction loss at 12 A, critical for high-efficiency power stages. |
| ID (continuous) | 12 A @ TA = +25°C - Sustained output capability with 2.2 W power dissipation on 1-in² copper pad. |
| VSD | 0.45 V @ IS = 1 A - Integrated Schottky reduces freewheeling loss by ~60% vs. standard MOSFET body diode. |
| Qrr | 4.3 nC - Low reverse recovery charge minimizes switching loss and EMI during hard commutation. |
| RθJA | 58 °C/W (with 1-in² copper) - Enables operation up to +125°C ambient in compact DC-DC modules. |
| trr | 13.1 ns - Fast recovery supports >500 kHz PWM frequencies without shoot-through risk. |
Pinout & Package
Package: PowerDI3333-8 - thermally enhanced, lead-free, halogen-free surface-mount package with exposed drain paddle for low RθJC = 11 °C/W; footprint occupies 3.3 × 3.3 mm, 33% area of SO-8.
| 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 low-inductance return path. |
| 5, 6, 7, 8 | Drain | Parallel-connected drain terminals linked to internal Schottky cathode; requires thermal pad connection to heatsink plane. |
| Gate | Control terminal | Single gate pad (pin not assigned; located between pins 4 and 5 per bottom view); accepts 4.5–10 V logic-level drive with 31.6 nC total gate charge. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic MOSFET + Schottky integration | Eliminates discrete diode placement, reduces layout parasitics, and cuts BOM count by one component. |
| Low Qrr / Qg ratio | Qrr = 4.3 nC, Qg = 31.6 nC → ratio = 0.136 - suppresses cross-conduction in synchronous rectification. |
| 100% UIS rated | Withstands 43 mJ single-pulse avalanche energy (EAS) - ensures robustness against inductive load transients. |
| Thermally optimized package | RθJA = 58 °C/W (1-in² copper) enables 12 A operation without forced air cooling in space-constrained modules. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - suitable for under-hood DC-DC converters. |

FAQ
What is the maximum junction temperature for DMS3012SFG-13?
The device is rated for TJ = –55°C to +150°C. With RθJA = 58 °C/W on a 1-inch square copper pad and 2.2 W power dissipation, maximum ambient temperature is +112°C before reaching 150°C junction limit - verified per JEDEC JESD51-2 thermal test conditions.
Is DMS3012SFG-13 pin-compatible with standard SO-8 MOSFETs?
No - it uses the PowerDI3333-8 package (3.3 × 3.3 mm), which has different pin spacing, thermal pad layout, and terminal assignment than SO-8 (4.9 × 6.0 mm). The pinout is non-interchangeable: all sources are on pins 1–4, all drains on pins 5–8, and gate is a center pad not aligned with SO-8 pin 1.
Does the integrated Schottky diode conduct during normal MOSFET turn-off?
Yes - the Schottky conducts during the dead-time interval when both high-side and low-side switches are off. Its forward voltage (VSD = 0.45 V @ 1 A) is significantly lower than the MOSFET's body diode (~1.2 V), reducing freewheeling loss and improving light-load efficiency.
Can DMS3012SFG-13 be used in linear regulator applications?
No - it is optimized for switching operation only. Its RDS(ON) variation over temperature (±30% from –55°C to +150°C) and lack of Safe Operating Area (SOA) characterization beyond pulsed conditions make it unsuitable for linear pass-element use.
