Product details
Overview
DMC2038LVTQ-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single TSOT26 package, integrating an N-channel (20V, 35mΩ @ 4.5V) and P-channel (-20V, 74mΩ @ -4.5V) device for half-bridge or level-shifting power stages. It delivers 4.5A/–3.1A continuous drain current at +25°C and supports motor control, DC-DC converters, and backlighting with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the DMC2038LVTQ-7 datasheet, DMC2038LVTQ-7 pinout, DMC2038LVTQ-7 application, or DMC2038LVTQ-7 equivalent, key selection criteria include dual-channel RDS(ON) matching at low gate drive (1.8V–4.5V), thermal resistance (RθJA = 114°C/W with 1-inch copper), and TSOT26 footprint compatibility for space-constrained power management designs.
Technical Context
This dual MOSFET implements complementary switching in a monolithic TSOT26 package, enabling compact high-side/low-side drive without external pairing. Its N-channel Q1 and P-channel Q2 share matched gate thresholds (±0.4–1.0V) and exhibit tightly coupled dynamic parameters: Ciss of 400–530pF (Q1) and 530–705pF (Q2), with tD(ON)/tD(OFF) under 20ns/40ns respectively.
The device uses a lead-free, halogen-free "Green" molding compound (UL 94V-0) and is qualified to AEC-Q101 for operation from –55°C to +150°C junction temperature. Thermal performance is specified for two PCB conditions: 0.8W/1.1W power dissipation on standard FR-4 (2oz Cu) and enhanced 1-inch copper plate layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V (N-ch) / –20V (P-ch): Supports 12V rail switching and 5V logic-level gate drive without level shifters. |
| RDS(ON) | 35mΩ @ 4.5V (Q1), 74mΩ @ –4.5V (Q2): Enables <1W conduction loss at 3A load in typical DC-DC phase-leg configurations. |
| ID Continuous | 4.5A (Q1), –3.1A (Q2) at TA = +25°C: Sustains motor stall currents and transient loads in automotive body electronics. |
| Ciss | 400–530pF (Q1), 530–705pF (Q2): Low input capacitance reduces gate drive power and enables >1MHz PWM operation. |
| tD(ON)/tD(OFF) | 5–10ns / 25–40ns (Q1); 11–20ns / 21–34ns (Q2): Fast switching minimizes overlap losses in synchronous rectification and H-bridge control. |
| RθJA | 114°C/W (enhanced layout): Allows 1.1W operation at ambient ≤70°C-critical for sealed automotive modules without forced airflow. |
| AEC-Q101 | Qualified: Meets stress test requirements for automotive power semiconductors including HTOL, TC, and ESD. |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (2.90 × 2.80 × 0.85 mm) with exposed drain pad for thermal relief; RoHS-compliant matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | N-channel source | Common source node for N-ch; ties to ground or low-side return path in half-bridge topologies. |
| 2 (G1) | N-channel gate | Direct logic-level input for PWM control; low Ciss enables drive from microcontroller GPIOs. |
| 3 (D1) | N-channel drain | Connects to load or high-side switch node; electrically isolated from P-ch drain (D2). |
| 4 (D2) | P-channel drain | Shared drain connection point with Q1 drain in common-drain configuration (e.g., level shifter). |
| 5 (G2) | P-channel gate | Inverted logic interface; pulled high to disable P-ch, driven low to activate-no external inverter needed. |
| 6 (S2) | P-channel source | Connects to VCC rail; forms high-side output when used as load switch or active pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary Pair Integration | Single TSOT26 package replaces discrete N+P MOSFETs-reduces PCB area by >40% and eliminates inter-device timing skew. |
| Low-Voltage Gate Drive Compatibility | Specified RDS(ON) down to VGS = 1.8V (Q1) and –1.8V (Q2), enabling direct interface with 1.8V/3.3V MCUs without gate drivers. |
| Fast Switching with Low Qg | Total gate charge of 5.7nC (Q1) and 7nC (Q2) at rated VGS, minimizing driver power and propagation delay in high-frequency converters. |
| AEC-Q101 Qualification | Validated for automotive applications including engine control modules, HVAC actuators, and LED lighting-ensures long-term reliability under thermal cycling and vibration. |
| Halogen- and Antimony-Free "Green" Construction | Meets JESD22-A112 (MSL Level 1) and EU RoHS 3 (2015/863/EU); <900ppm Br, <900ppm Cl, <1000ppm Sb-supports eco-design compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2053UVT | Higher RDS(ON): 48mΩ/105mΩ @ ±4.5V; lower ID: 3.8A/–2.7A; same TSOT26 package. | Better suited for cost-sensitive consumer applications where 15% higher conduction loss is acceptable. | Select when thermal margin exceeds 20°C and AEC-Q101 is not required-offers 12% lower unit cost. |
| Si3588DV-T1-GE3 | Discrete dual N/P pair in SC-70-6; RDS(ON) 40mΩ/85mΩ @ ±4.5V; no AEC-Q101 qualification. | Limited to industrial/commercial use; lacks automotive stress testing and MSL Level 1 moisture rating. | Choose only for non-automotive prototypes where board space is less constrained and qualification traceability is not mandated. |
Compared with DMC2038LVTQ-7, DMC2053UVT trades 20% higher RDS(ON) for lower cost and broader commercial availability, while Si3588DV-T1-GE3 sacrifices automotive reliability for legacy footprint compatibility-neither matches the original's combination of AEC-Q101, 1.8V drive, and thermal performance in TSOT26.

FAQ
What is the maximum safe operating junction temperature for DMC2038LVTQ-7?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Operation above +125°C requires derating based on RθJA = 114°C/W (enhanced layout) and must maintain TJ ≤ 150°C under worst-case ambient and power dissipation. Thermal shutdown is not integrated-external monitoring is required for safety-critical designs.
Can DMC2038LVTQ-7 be used in a common-source configuration for high-side switching?
No-it is not designed for common-source high-side use. The P-channel device (Q2) has its source tied to VCC and drain to the load, requiring gate drive referenced to VCC. For true high-side switching with ground-referenced control, a dedicated high-side driver IC or bootstrap circuit is necessary; this device functions optimally in common-drain (source-follower) or half-bridge arrangements.
Is the TSOT26 package of DMC2038LVTQ-7 compatible with standard reflow profiles?
Yes-the TSOT26 package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 20–40s above 217°C). The exposed drain pad improves thermal transfer but does not require solder paste stencil modification beyond Diodes' recommended pad layout (available in DS35417 Rev. 9, page 9).
Does DMC2038LVTQ-7 include integrated ESD protection on gate terminals?
Yes-each gate terminal (G1 and G2) is protected to ≥2kV HBM per JEDEC JS-001, verified during AEC-Q101 qualification. This allows direct handling and assembly without additional gate protection diodes in most automotive and industrial environments, though system-level TVS remains recommended for load-dump or inductive switching transients.
