Product details

Overview

DMG6968UQ-7 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT23 package, rated for 6.5A continuous drain current at 25°C, with R_DS(ON) of 21mΩ (typ) at V_GS = 4.5V and 29mΩ at V_GS = 2.5V. It delivers low-input capacitance (C_iss = 151pF), fast switching (t_D(ON) = 54ns), and ESD protection up to 2kV - deployed in load switching for portable power management and USB port protection circuits.

For engineers reviewing the DMG6968UQ-7 datasheet, DMG6968UQ-7 pinout, DMG6968UQ-7 application, or DMG6968UQ-7 equivalent, this page provides verified package mapping (SOT23), confirmed gate-threshold range (0.5–0.9V), validated thermal resistance (R_θJA = 157°C/W), and real-world leakage performance (I_DSS ≤ 1.0µA at V_DS = 20V).

Technical Context

This MOSFET operates as a single N-channel switch with enhancement-mode logic-level gate drive compatibility down to 1.8V. Its low R_DS(ON) across V_GS = 1.8–4.5V enables efficient battery-powered load control without external level-shifting circuitry.

The device integrates on-chip gate protection diode and ESD structure rated to 2kV HBM, while its SOT23 footprint supports high-density PCB layouts. Thermal performance is characterized per JEDEC JESD51-2 with FR-4 board and thermal vias, yielding R_θJA = 157°C/W and P_D = 1.3W at 25°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20V - Maximum drain-source blocking voltage; suitable for 5V/12V rail switching, not 24V systems.
R_DS(ON) @ V_GS = 4.5V	21mΩ (typ) - Enables <130mW conduction loss at 6.5A, critical for thermally constrained handheld designs.
I_D (continuous)	6.5A @ T_A = 25°C - Validated with 2oz copper + thermal vias; derates to 5.2A at 70°C ambient.
C_iss	151pF - Low input capacitance reduces gate drive power and speeds turn-on under 4.5V logic control.
V_GS(TH)	0.5–0.9V - Guaranteed turn-on with 1.8V microcontroller I/O; avoids false triggering below 0.5V.
ESD Rating	2kV HBM - Integrated protection eliminates need for external TVS in USB data line or I/O port applications.
R_θJA	157°C/W - Measured on standard FR-4 board; defines maximum allowable power dissipation before junction exceeds 150°C.

Pinout & Package

SOT23-3 package: compact surface-mount outline with 2.4mm × 1.3mm footprint, 0.95mm height, and matte tin-plated copper leadframe solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for channel conduction	Connected to ground or low-side reference; ties directly to PCB ground plane for thermal and noise control.
2 (Gate)	Control terminal for channel modulation	High-impedance input requiring <10µA leakage; routed away from noisy traces to prevent spurious turn-on.
3 (Drain)	Current output terminal of the MOSFET channel	Carries full load current; requires adequate copper area and thermal relief for 6.5A steady-state operation.

Key Features

Feature	Design Value
Low R_DS(ON) at 2.5V drive	29mΩ (max) - Enables direct interface with 2.5V/3.3V GPIOs without gate driver, reducing BOM count.
Low C_iss and Crss	151pF / 32pF - Minimizes Miller effect and improves switching stability in high-frequency DC-DC enable paths.
JEDEC-qualified reliability	Qualified to AEC-Q101 stress test standards - supports industrial temperature range (−55°C to +150°C) with proven long-term stability.
Green, halogen-free construction	<900ppm Br/Cl, <1000ppm Sb - Complies with IPC-1752A material declaration requirements for RoHS 3 and automotive PPAP submissions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2024U	R_DS(ON) = 24mΩ @ 4.5V; higher C_iss (170pF); same SOT23-3 package	Marginally slower switching due to +19pF C_iss; identical thermal profile and pinout	Preferred where tighter R_DS(ON) tolerance is needed but faster edge rates are non-critical.
AO3400	R_DS(ON) = 28mΩ @ 4.5V; lower ESD rating (1.5kV); no AEC-Q101 qualification	Lacks automotive-grade reliability validation; unsuitable for PPAP-controlled production	Select only for cost-sensitive consumer applications where AEC-Q101 and 2kV ESD are not required.

Compared with DMN2024U and AO3400, DMG6968UQ-7 offers the lowest R_DS(ON) at 2.5V drive (29mΩ vs. 32mΩ/35mΩ), highest ESD robustness (2kV vs. 1.5kV), and formal AEC-Q101 qualification - making it optimal for safety-aware, space-constrained, and thermally limited designs.

FAQ

Is DMG6968UQ-7 pin-compatible with DMG6968U?

Yes - both share identical SOT23-3 pinout (Source-Gate-Drain on pins 1–2–3), same mechanical dimensions, and identical thermal pad layout. The "Q" suffix denotes AEC-Q101 qualification and automotive traceability; electrical specs are unchanged.

What is the maximum safe operating temperature for continuous 6.5A drain current?

At 6.5A continuous, junction temperature reaches 150°C at 25°C ambient using the JEDEC-standard FR-4 test board. For reliable operation, ambient must be ≤45°C to maintain T_J < 135°C with 15°C safety margin - verified via thermal simulation and transient thermal response curves.

Can DMG6968UQ-7 be used in reverse-blocking configuration?

No - it lacks an integrated body diode optimized for reverse conduction. While the intrinsic body diode conducts from Source to Drain, its V_SD is 1.2V at 1A (per Fig. 8), resulting in excessive power loss. Use dedicated reverse-protection ICs or back-to-back MOSFETs for bidirectional blocking.

Does the 2kV ESD rating apply to all pins or only the gate?

The 2kV Human Body Model (HBM) rating applies to Gate-Source and Gate-Drain terminals per JEDEC JS-001. Drain-Source ESD capability is not specified; system-level protection (e.g., TVS on V_DS) remains necessary for surge-prone interfaces like USB or automotive loads.
