Product details

Overview

DMN4035L-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 40V V_DSS, 42 mΩ R_DS(ON) @ 10V V_GS, and 4.6A continuous drain current - optimized for high-efficiency DC-DC converters and portable power adaptors where low conduction loss and fast switching are critical.

For engineers reviewing the DMN4035L-13 datasheet, DMN4035L-13 pinout, DMN4035L-13 application, or DMN4035L-13 equivalent, key selection criteria include its 4.5V gate drive compatibility (52 mΩ R_DS(ON)), 574 pF C_iss, 12.5 nC total gate charge at 10V, thermal resistance of 93°C/W under enhanced layout, and JEDEC-qualified reliability for industrial power management designs.

Technical Context

This MOSFET employs planar trench-gate technology to achieve low R_DS(ON) while maintaining controlled Q_g (12.5 nC @ 10V) and fast switching (t_r = 2.6 ns, t_f = 5.5 ns). Its V_GS(TH) range (1–3 V) ensures robust turn-on with standard logic-level drivers.

Designed for unidirectional power switching in synchronous buck topologies, it integrates a body diode with V_SD = 0.7–1.1 V @ 1.25 A and t_RR = 6.5 ns, enabling efficient freewheeling in compact DC-DC stages without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage in high-side or low-side switch configurations without avalanche breakdown.
R_DS(ON)	42 mΩ @ V_GS = 10 V, I_D = 4.3 A - Enables ≤180 mW conduction loss at 4.6 A, critical for thermally constrained portable designs.
I_D (continuous)	4.6 A @ T_A = 25°C - Supports sustained load currents in 1–3 W power rails when mounted on 2 oz copper FR-4 with thermal bias.
C_iss	574 pF @ V_DS = 20 V - Limits gate drive power requirement and enables clean switching with low-impedance 6 Ω gate resistor.
t_r/t_f	2.6 ns / 5.5 ns @ V_DD = 20 V, R_G = 6 Ω - Reduces switching transition time, minimizing overlap loss in 500 kHz–1 MHz converters.
Q_g	12.5 nC @ V_GS = 10 V - Determines gate driver current demand (e.g., 1.25 A peak for 10 ns rise) in high-frequency PWM control.

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin–annealed copper leadframe, UL 94V-0 rated, moisture sensitivity level 1, weight ≈ 0.008 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for drain current	Connected to ground or low-side reference; forms body diode cathode; requires low-inductance layout for EMI control.
2 (Gate)	Control terminal for channel modulation	High-impedance input requiring RC snubber or gate resistor (6 Ω typical) to damp ringing and limit dV/dt-induced shoot-through.
3 (Drain)	Main power output node	Carries switched load current; connects to inductor or input rail; must be routed with minimal loop area to reduce radiated noise.

Key Features

Feature	Design Value
Low R_DS(ON) at 4.5 V	52 mΩ - Enables full-load operation with 3.3 V or 5 V microcontroller GPIOs without level-shifting.
Fast switching speed	t_D(ON) = 3.1 ns, t_F = 5.5 ns - Reduces energy loss per cycle in high-frequency DC-DC regulators (≥1 MHz).
Low gate charge	Q_g = 5.9 nC @ 4.5 V - Lowers average gate drive power, easing thermal design for integrated FET controllers.
JEDEC-qualified reliability	Qualified to AEC-Q standards for high-reliability industrial use - supports long-term deployment in non-automotive embedded power systems.

Applications

Battery Charging Circuits

USB-C Power Delivery Adaptors

Use Scenario: Synchronous rectification in 5–20 V, 3–5 A battery charging paths for Li-ion packs in portable medical devices.

IC Role / Device Role: Low-side switch replacing Schottky diode to reduce forward drop and improve efficiency by ≥8% at 3 A.

Use Value: 42 mΩ R_DS(ON) cuts conduction loss to <190 mW vs. >500 mW for 40 V/3 A Schottky, extending runtime and reducing thermal pad area.

Use Scenario: Output-side power switch in compact 27 W USB-C PD adaptors with 9 V/3 A or 15 V/1.8 A profiles.

IC Role / Device Role: Secondary-side synchronous FET in flyback or active-clamp forward topology.

Use Value: 574 pF C_iss and 12.5 nC Q_g allow clean 600 kHz switching with minimal gate drive loss, supporting >92% peak efficiency.

Point-of-Load DC-DC Converters

Portable Power Bank Management

Use Scenario: High-side switch in 12 V input → 3.3 V/5 V buck converters for FPGA I/O banks or sensor subsystems.

IC Role / Device Role: Main switching element in discrete or controller-based buck stage operating at 1–2 MHz.

Use Value: 2.6 ns rise time and 5.5 ns fall time minimize dead-time losses, enabling stable regulation under dynamic 10 A/μs load transients.

Use Scenario: Load switch between Li-ion cell and USB OTG output port in dual-role power banks.

IC Role / Device Role: Reverse-current blocking and soft-start controlled power path switch.

Use Value: V_GS(TH) = 1–3 V ensures reliable turn-on with 3.3 V system rail; 1.5 A body diode rating supports safe reverse-conduction during hot-plug events.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3029L-13	30 V V_DSS, 29 mΩ R_DS(ON) @ 10 V, same SOT23 package	Lower voltage rating limits use to ≤24 V systems; better R_DS(ON) improves efficiency below 30 V but sacrifices 40 V margin.	Select when input voltage is strictly ≤24 V and ultra-low conduction loss is prioritized over voltage headroom.
AO3400A	30 V V_DSS, 42 mΩ R_DS(ON) @ 10 V, 4.2 A I_D, same footprint	Lower continuous current rating (4.2 A vs. 4.6 A) and higher C_iss (750 pF) increase switching loss at >500 kHz.	Acceptable for cost-sensitive 30 V applications with moderate frequency; verify thermal margin at full load due to 100°C/W R_θJA.

Compared with DMN3029L-13 and AO3400A, DMN4035L-13 uniquely balances 40 V capability, 4.6 A current handling, and 574 pF input capacitance - making it the preferred choice for 36 V nominal input DC-DC stages where both voltage margin and high-frequency efficiency matter.

FAQ

What is the maximum junction temperature for DMN4035L-13?

The DMN4035L-13 has a specified operating junction temperature range of –55°C to +150°C. Its absolute maximum T_J is 150°C, and thermal derating begins above 25°C ambient based on R_θJA = 93°C/W under enhanced PCB layout (2 oz copper with thermal bias). Exceeding 150°C risks permanent parametric shift or failure.

Is DMN4035L-13 suitable for automotive applications?

DMN4035L-13 is not AEC-Q200 qualified. For automotive use, Diodes offers the pin-compatible DMN4035LQ variant - qualified to AEC-Q101, manufactured in IATF 16949 facilities, and PPAP-capable. The standard DMN4035L-13 is intended for industrial, computing, and consumer power management only.

What is the gate threshold voltage range, and how does it affect drive requirements?

V_GS(TH) is specified from 1 V to 3 V at I_D = 250 μA. This allows reliable turn-on with 3.3 V logic, but full enhancement (≤42 mΩ R_DS(ON)) requires ≥10 V V_GS. At 4.5 V, R_DS(ON) rises to 52 mΩ - acceptable for many portable applications but necessitates verification of conduction loss versus thermal budget.

Does DMN4035L-13 have integrated ESD protection?

No integrated ESD protection structure is specified in the datasheet. The device exhibits ±20 V gate-source rating (V_GSS) and ±100 nA gate leakage at ±20 V, indicating standard MOSFET gate oxide robustness - but external TVS or RC filtering is recommended on gate traces in noisy environments to prevent electrostatic damage during handling or operation.
