Product details
Overview
DMN53D0LW-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT323 package, rated for 50V VDSS, 2.0Ω RDS(ON) @ 10V VGS, and 360mA continuous drain current at 25°C. It delivers low on-resistance and fast switching for compact DC-DC converters and battery-powered load switching.
For engineers reviewing the DMN53D0LW-13 datasheet, DMN53D0LW-13 pinout, DMN53D0LW-13 application, or DMN53D0LW-13 equivalent, key selection criteria include gate threshold voltage (0.8–1.5V), input capacitance (45.8pF), ESD-protected gate, thermal resistance (395°C/W), and SOT323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This MOSFET operates as a low-voltage, low-current single-N-channel switch with integrated gate protection diode and ESD-hardened gate oxide. Its 0.73Ω typical RDS(ON) at 10V enables efficient power delivery in portable systems where conduction loss dominates.
The device features a 1.2nC total gate charge and 2.7ns turn-on delay, supporting high-frequency PWM control up to several hundred kHz. Its -55°C to +150°C operating range and JEDEC-qualified reliability suit industrial and extended-temperature embedded applications.
Key Specifications

| VDSS | 50V - supports input rails up to 48V nominal without breakdown risk |
| RDS(ON) | 2.0Ω @ 10V VGS - limits I²R loss to ≤180mW at 300mA, enabling passive cooling |
| ID (continuous) | 360mA @ 25°C - suitable for driving small solenoids, LEDs, or logic-level loads |
| Ciss | 45.8pF - reduces gate drive power requirement and improves switching efficiency |
| Qg | 1.2nC @ 10V - enables clean 2.7ns turn-on with minimal external gate resistor |
| TJ range | -55°C to +150°C - qualified for operation in automotive under-hood or industrial ambient environments |
| PD | 320mW - defines maximum steady-state power dissipation on standard FR-4 board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LK-7 | Higher RDS(ON) (3.5Ω @ 4.5V), same SOT323 package, lower VDSS (20V) | Limited to ≤12V systems; less efficient at 5–12V loads | Select when cost sensitivity outweighs conduction loss in low-voltage consumer gear |
| NX138AK,115 | Lower RDS(ON) (1.2Ω @ 4.5V), same 50V rating, higher ID (500mA), SOT323 | Better thermal margin and drive capability for sustained 400mA loads | Prefer for higher-current or thermally constrained applications requiring tighter RDS(ON) tolerance |
Compared with DMN53D0LW-13, DMN2004LK-7 trades conduction efficiency for cost in sub-12V systems, while NX138AK,115 offers superior RDS(ON) and current headroom at comparable price-making it ideal for designs pushing thermal limits or requiring tighter gate threshold consistency.

FAQ
What is the maximum continuous drain current for DMN53D0LW-13 at 70°C ambient?
The DMN53D0LW-13 supports 250mA continuous drain current at TA = +70°C when VGS = 10V, and 200mA at VGS = 5V. This derating reflects thermal limitations of the 320mW power dissipation rating on standard FR-4 PCBs with minimal copper area.
Does DMN53D0LW-13 include an integrated body diode?
Yes, DMN53D0LW-13 contains an intrinsic parasitic body diode with forward voltage of 0.75–1.2V at 115mA source current. The diode anode connects to the source terminal and cathode to the drain, enabling freewheeling in inductive switching applications without external components.
Can DMN53D0LW-13 be driven directly by a 3.3V microcontroller GPIO?
Yes - its gate threshold voltage ranges from 0.8V to 1.5V, and RDS(ON) drops to 3.0Ω at VGS = 5V and 250mA ID. At 3.3V, it achieves partial enhancement; for reliable saturation, use with 5V logic or ensure load current stays ≤150mA to maintain acceptable on-resistance.
Is DMN53D0LW-13 qualified for automotive applications?
No - DMN53D0LW-13 is not AEC-Q101 qualified. Diodes offers automotive-grade equivalents (e.g., DMN53D0LWQ-13) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. Use only the Q-suffix variant for automotive under-hood or safety-critical systems.
