Product details
Overview
DMG1029SV-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in SOT563 package, integrating one N-channel (60V, 1.7Ω @ 10V) and one P-channel (–60V, 4Ω @ –10V) device for bidirectional switching in compact power management circuits. It delivers low gate threshold voltage (1.0–2.5V for Q1, –1.0 to –3.0V for Q2), fast switching (tD(on) ≤ 5.5ns for Q2), and ultra-small footprint for space-constrained DC-DC converters and load switches.
For engineers reviewing the DMG1029SV-7 datasheet, DMG1029SV-7 pinout, DMG1029SV-7 application, or DMG1029SV-7 equivalent, key selection criteria include complementary VDS rating symmetry, RDS(on) matching at 4.5V/–4.5V, thermal resistance (RθJA = 129°C/W under 1-in² copper), and AEC-Q101 qualification for automotive-grade reliability validation.
Technical Context
This dual MOSFET implements independent N- and P-channel channels sharing a common SOT563 thermally optimized leadframe. Each channel features low-input capacitance (Ciss = 30pF / 25pF), tightly controlled VGS(th) windows, and body diodes with VSD = ±1.4V rated at ±115mA - enabling efficient synchronous rectification and bidirectional current control without external diodes.
The device operates across –55°C to +150°C junction temperature, with pulsed drain current ratings of 1A (Q1) and –650mA (Q2), and thermal derating defined for both steady-state (RθJA = 281°C/W on minimal pad) and enhanced layout (RθJA = 129°C/W on 1-in² copper). Gate charge values (Qg = 0.3nC / 0.28nC) support high-frequency PWM operation up to several MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 60V (N-ch), –60V (P-ch): Enables rail-to-rail switching in 24V/48V industrial and automotive supply domains. |
| RDS(on) @ VGS = 10V/–10V | 1.7Ω (Q1), 4Ω (Q2): Supports ≥500mA continuous conduction with <0.425W conduction loss at full load. |
| RDS(on) @ VGS = 4.5V/–4.5V | 3Ω (Q1), 6Ω (Q2): Ensures functional switching down to 3.3V logic-level drive in battery-powered systems. |
| Qg | 0.3nC (Q1), 0.28nC (Q2): Minimizes gate drive power and enables <10ns switching transitions with 25Ω source impedance. |
| TJ Range | –55°C to +150°C: Qualified for under-hood automotive and industrial ambient environments without derating. |
| PD (1-in² copper) | 1W at +25°C: Allows sustained 500mA operation in compact PCB layouts with localized thermal relief. |
Pinout & Package
SOT563 is a 6-pin ultra-thin, lead-free surface-mount package (1.6mm × 1.2mm × 0.5mm) with exposed thermal pad and matte tin-plated copper leadframe. Its symmetrical pin arrangement supports dual-channel routing with minimal board area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | N-channel gate | Logic-level input for high-side N-MOS control; requires no level-shifting when driven by 3.3V/5V microcontrollers. |
| 2 (S1) | N-channel source | Common source node for N-ch; connects to ground or low-side return path in half-bridge configurations. |
| 3 (D1) | N-channel drain | High-side output node; carries load current to VIN in high-side switch applications. |
| 4 (D2) | P-channel drain | Low-side output node; sinks current from load to ground in complementary switching topologies. |
| 5 (S2) | P-channel source | Common source node for P-ch; ties to VIN in high-side P-MOS or bidirectional switch designs. |
| 6 (G2) | P-channel gate | Inverted logic input; active-low control enables direct interface with open-drain drivers or inverted PWM signals. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary channel pairing | Matched VDS, VGS(th), and RDS(on) tolerance enables balanced push-pull and H-bridge operation without external balancing components. |
| Low gate threshold voltage | VGS(th) = 1.0–2.5V (Q1), –1.0 to –3.0V (Q2) ensures reliable turn-on with standard logic outputs and reduces gate drive complexity. |
| Ultra-small SOT563 footprint | 1.6mm × 1.2mm outline saves >60% board area vs. discrete SO-8 dual MOSFETs, critical for wearables and portable medical devices. |
| AEC-Q101 qualification | Validated for automotive applications including body control modules and LED lighting drivers requiring PPAP documentation and zero-defect reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2053LW-7 | Single N-channel only (20V, 0.045Ω), no P-channel complement; requires external P-MOS for bidirectional use. | Limited to high-side-only or discrete half-bridge designs; lacks integrated thermal tracking between channels. | Select when only N-ch switching is needed and board space allows separate P-MOS placement. |
| FDMA1027NZ | Complementary pair in WDFN-6 (2×2mm); RDS(on) = 2.2Ω/4.5Ω @ 4.5V, higher Ciss (42pF/35pF), no AEC-Q101 rating. | Suitable for consumer-grade power tools but not qualified for automotive temperature cycling or humidity testing. | Prefer for cost-sensitive non-automotive applications where 0.4mm height tolerance permits larger package. |
Compared with DMN2053LW-7 and FDMA1027NZ, DMG1029SV-7 uniquely combines AEC-Q101 qualification, matched complementary RDS(on) at logic-level drive, and smallest industry-standard footprint - making it optimal for space- and reliability-critical automotive and portable medical systems.

FAQ
What is the maximum continuous drain current for each channel at +70°C ambient?
At TA = +70°C, the N-channel (Q1) supports 400mA continuous drain current with VGS = 10V, while the P-channel (Q2) supports –280mA with VGS = –10V. These values reflect thermal derating per the datasheet's "Steady State" condition on FR-4 with minimum pad layout; using 1-inch square copper increases Q1 to 480mA and Q2 to –320mA.
Can DMG1029SV-7 be used in a synchronous buck converter as high-side and low-side switches?
No - DMG1029SV-7 integrates one N-channel and one P-channel MOSFET, but its P-channel is not optimized for low-side synchronous rectification due to higher RDS(on) (4Ω vs. typical <10mΩ in dedicated low-side N-MOS). It is designed for complementary load switching, not power-stage topology replacement. Use discrete N-N pairs like DMN3029LSD-13 for true synchronous buck stages.
Is the SOT563 package thermally enhanced, and how does it compare to SOT23-6?
Yes - the SOT563 package features an exposed thermal pad and 0.5mm profile optimized for heat dissipation in ultra-thin assemblies. Compared to SOT23-6, it offers 35% smaller footprint (1.6×1.2mm vs. 2.9×1.6mm) and lower RθJA (129°C/W vs. ~200°C/W on identical copper area), enabling higher power density in wearable and implantable electronics.
Does the DMG1029SV-7 meet halogen-free and antimony-free "Green" requirements?
Yes - DMG1029SV-7 is certified halogen- and antimony-free per Diodes Incorporated's "Green" definition: Br < 900ppm, Cl < 900ppm (total Br+Cl < 1500ppm), and Sb < 1000ppm. It is also fully RoHS 2 compliant (2011/65/EU) with matte tin annealed leadframe and green molding compound rated UL 94V-0.
