Product details
Overview
DMN53D0LTQ-13 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT523 package, rated for 50 V VDSS, 1.6 Ω RDS(ON) @ 10 V VGS, and 350 mA continuous drain current at +25°C - designed for automotive load switching in space-constrained ECUs and body control modules.
For engineers reviewing the DMN53D0LTQ-13 datasheet, DMN53D0LTQ-13 pinout, DMN53D0LTQ-13 application, or DMN53D0LTQ-13 equivalent, key selection criteria include low gate threshold (0.8–1.5 V), ultra-small footprint, AEC-Q101 qualification, and verified performance under -55°C to +150°C junction temperature range.
Technical Context
This discrete MOSFET operates as a low-side switch with enhancement-mode gate control, optimized for DC load switching where fast turn-on (tD(ON) = 2.7 ns) and low dynamic losses (Qg = 1.4 nC @ 10 V) are critical. Its 0.88 V typical source-drain diode forward voltage supports bidirectional current handling in motor commutation paths.
The device uses a fully lead-free, halogen- and antimony-free "Green" molding compound (UL 94V-0), with matte tin-plated Alloy 42 leadframe and J-STD-020 Level 1 moisture sensitivity - enabling reflow compatibility without baking in automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 50 V - supports 24 V automotive systems with ≥100% safety margin against transients. |
| RDS(ON) | 1.6 Ω @ VGS = 10 V - enables ≤0.28 W conduction loss at 350 mA, minimizing thermal rise on FR-4 boards. |
| VGS(TH) | 0.8–1.5 V - ensures reliable turn-on with 3.3 V or 5 V logic-level microcontrollers without level-shifting. |
| Ciss | 46 pF - reduces gate drive power requirement and improves switching efficiency in high-frequency PWM loads. |
| PD | 300 mW - defines maximum steady-state power dissipation on standard 1-inch² 2 oz copper pad layout. |
| TJ Range | -55°C to +150°C - meets extended temperature requirements for engine bay and transmission control units. |
| Qg | 1.4 nC @ 10 V - determines gate driver current demand for <30 ns total switching time in 100 kHz+ applications. |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), UL 94V-0 rated, with 0.50 mm lead pitch and 0.002 g mass. Designed for high-density automotive PCBs with minimal board area impact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN5L05TQ-13 | Lower RDS(ON) (0.8 Ω @ 10 V), higher ID (500 mA), same SOT523 package and AEC-Q101 qualification. | Better suited for higher-current solenoids or dual-motor drivers where thermal headroom is constrained. | Select when >350 mA continuous load current or lower conduction loss is required without changing PCB layout. |
| DMN3022LFG-7 | Higher VDSS (30 V), smaller RDS(ON) (0.45 Ω @ 4.5 V), WDFN-6 package (1.5 × 1.5 mm), AEC-Q101 qualified. | Offers superior thermal performance (RθJA = 120°C/W) but requires different footprint and solder stencil design. | Choose for thermally demanding applications where board space allows WDFN-6 and higher current density is needed. |
Compared with DMN5L05TQ-13 and DMN3022LFG-7, the DMN53D0LTQ-13 provides optimal balance of ultra-small size, low-threshold drive, and proven reliability in cost-sensitive, space-limited automotive modules - especially where 350 mA load current and 50 V transient tolerance define the operating envelope.

FAQ
Is DMN53D0LTQ-13 suitable for 3.3 V microcontroller gate drive?
Yes. With a gate threshold voltage range of 0.8–1.5 V and guaranteed turn-on at VGS = 2.5 V (RDS(ON) = 4.5 Ω), the DMN53D0LTQ-13 fully enhances using standard 3.3 V GPIO outputs. Its low input capacitance (46 pF) further reduces drive current demand.
What is the maximum pulsed drain current rating?
The DMN53D0LTQ-13 supports 1.0 A pulsed drain current under 10 µs pulse width and 1% duty cycle conditions, as specified in the Absolute Maximum Ratings table. This enables short-duration surge handling in motor startup or solenoid actuation events.
Does this MOSFET require external gate resistor for automotive EMI compliance?
A 10–22 Ω series gate resistor is recommended to dampen ringing caused by parasitic inductance in PCB traces, especially in high-speed PWM applications. The device's 51 Ω intrinsic gate resistance helps limit peak dI/dt, but external tuning ensures robust EMC performance per CISPR 25 Class 5.
Can DMN53D0LTQ-13 replace older SOT-23 MOSFETs in existing designs?
No - the SOT523 package is physically smaller than SOT-23 (1.6 × 1.6 mm vs. 2.9 × 1.3 mm) and has different pinout (G-S-D vs. G-D-S). Direct replacement requires PCB redesign, though the electrical specs allow functional equivalence in new compact layouts.
