Product details
Overview
DMG2302UKQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 20V VDSS, 90mΩ RDS(ON) @ 4.5V VGS, and 2.8A continuous drain current at +25°C. It features ESD-protected gate, low input capacitance (130pF Ciss), and fast switching (tR = 2.7ns), enabling use in automotive backlighting and DC-DC converter power stages.
For engineers reviewing the DMG2302UKQ-13 datasheet, DMG2302UKQ-13 pinout, DMG2302UKQ-13 application, or DMG2302UKQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 2.5V logic-level gate drive capability, 120mΩ RDS(ON) @ 2.5V, thermal resistance of 115°C/W on high-copper PCB, and PPAP-capable automotive supply chain support.
Technical Context
This MOSFET operates as a low-side switch in automotive power management circuits, with gate threshold voltage (VGS(TH)) tightly specified from 0.3V to 1.0V and stable across −55°C to +150°C junction temperature. Its body diode supports synchronous rectification in buck converters, with VSD = 0.7–1.2V at 1.0A and tRR = 5.3ns.
The device uses a planar trench process optimized for low RDS(ON) × Qg figure-of-merit (61mΩ × 1.4nC), enabling high-efficiency operation at switching frequencies up to 1MHz. Thermal performance is characterized for both minimum-pad (192°C/W) and high-copper (115°C/W) FR-4 layouts.

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 |
|---|---|---|---|
| DMN2020LFG-7 | Same SOT23 package; lower RDS(ON) (50mΩ @ 4.5V) but higher Qg (2.5nC); not AEC-Q101 qualified | Preferred for non-automotive consumer DC-DC where cost and efficiency outweigh qualification needs | Select when AEC-Q101 is not required and lower conduction loss justifies higher gate drive demand |
| AO3400 | Same 20V rating and SOT23 footprint; RDS(ON) = 44mΩ @ 4.5V but no AEC-Q101 or PPAP support; higher Ciss (370pF) | Suitable for industrial motor drivers where thermal margin exceeds automotive requirements | Choose for legacy designs needing drop-in replacement with improved RDS(ON), accepting reduced switching speed |
Compared with DMN2020LFG-7 and AO3400, DMG2302UKQ-13 uniquely delivers AEC-Q101 reliability, PPAP readiness, and balanced RDS(ON)/Qg for automotive-grade 2.5V–4.5V gate drive systems-making it the only option qualified for safety-critical lighting and power management functions.

FAQ
What is the maximum gate-source voltage rating for DMG2302UKQ-13?
The absolute maximum VGS is ±12V per the datasheet's "Maximum Ratings" table. Exceeding this risks permanent gate oxide damage. For robust operation, gate drive should be limited to 0–8V in standard applications, with transient spikes clamped by external Zener diodes if needed.
Does DMG2302UKQ-13 support 2.5V logic-level drive?
Yes. With VGS(TH) min = 0.3V and RDS(ON) = 120mΩ @ 2.5V VGS, the device fully enhances using standard 2.5V CMOS outputs. This eliminates need for gate drivers in low-power automotive modules like sensor power switches and LED dimming circuits.
How does the thermal performance differ between minimum-pad and high-copper PCB layouts?
On a standard FR-4 board with minimum pad layout, RθJA = 192°C/W; on a 1″×1″ board with 2oz copper, it improves to 115°C/W. This 40% reduction allows 2.8A continuous current at +25°C ambient versus 1.7A on minimal layout-critical for space-constrained automotive modules.
Is DMG2302UKQ-13 suitable for synchronous rectification in buck converters?
Yes. Its body diode has VSD = 0.7–1.2V at 1.0A and tRR = 5.3ns, enabling efficient synchronous operation at up to 1MHz. Combined with low Qgd (0.5nC), it minimizes cross-conduction losses when paired with a complementary high-side switch.
