Product details

Overview

DMN3033LSNQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SC-59 package, rated for 30V V_DSS, 6A continuous drain current at 25°C, and 30mΩ R_DS(on) at V_GS = 10V. It delivers low gate charge (10.5nC) and fast switching for high-efficiency DC-DC converters and motor control in automotive and industrial power management.

For engineers reviewing the DMN3033LSNQ-13 datasheet, DMN3033LSNQ-13 pinout, DMN3033LSNQ-13 application, or DMN3033LSNQ-13 equivalent, key selection criteria include its 4.5V logic-level gate drive capability, 90°C/W thermal resistance on FR-4 PCB, AEC-Q101 qualification, and SC-59 footprint compatibility with space-constrained board layouts.

Technical Context

This MOSFET operates as a single N-channel power switch with enhancement-mode threshold (V_GS(th) = 1.0–2.1V) and integrated body diode (V_SD = 0.7–1.1V at 2.25A). Its dynamic parameters-Q_g = 10.5nC, Q_gd = 2.9nC, and t_D(off) = 63ns-support high-frequency synchronous rectification and PWM-driven loads.

The device uses a copper leadframe with matte tin annealed terminals and green molding compound (UL 94V-0), meeting J-STD-020 Level 1 moisture sensitivity. Thermal performance is specified for 1"×1" FR-4 board with 2 oz. copper, enabling reliable operation up to +150°C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - Maximum drain-source blocking voltage before avalanche conduction begins
R_DS(on) @ V_GS = 10V	30mΩ max - On-resistance at full gate drive, defining conduction loss in 6A continuous load paths
R_DS(on) @ V_GS = 4.5V	40mΩ max - Confirmed logic-level drive capability compatible with 3.3V/5V microcontrollers
Q_g	10.5nC - Total gate charge determining driver strength requirement and switching energy loss
t_D(off)	63ns - Turn-off delay time critical for minimizing shoot-through risk in half-bridge topologies
P_D @ T_A = 25°C	1.4W - Power dissipation limit on standard FR-4 PCB, constraining thermal design margin
T_J Range	−55°C to +150°C - Junction temperature range supporting under-hood automotive and industrial ambient conditions

Pinout & Package

Package: SC-59 (SOT-23 variant), surface-mount, 3-terminal plastic case with matte tin-plated copper leadframe; UL 94V-0 rated, 0.014g weight, moisture sensitivity Level 1.

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
DMN3023LSD-13	Lower R_DS(on) (23mΩ @ 10V), same SC-59 package, higher Q_g (14.5nC)	Better conduction loss but slower switching; less suitable for >1MHz DC-DC	Select when thermal headroom is limited and switching frequency ≤500kHz
AO3400	Same V_DSS/R_DS(on) specs, but not AEC-Q101 qualified; TO-236AB package	Not approved for automotive use; lacks PPAP documentation and stress test validation	Select only for non-automotive industrial or consumer applications requiring cost optimization

Compared with DMN3033LSNQ-13, DMN3023LSD-13 trades faster switching for lower conduction loss, while AO3400 omits automotive qualification and reliability testing-making DMN3033LSNQ-13 the sole choice where AEC-Q101 compliance and balanced R_DS(on)/Q_g are required.

FAQ

Is DMN3033LSNQ-13 suitable for 12V automotive battery systems?

Yes. With 30V V_DSS, −55°C to +150°C operating range, and AEC-Q101 qualification, it supports 12V nominal systems including load dump transients up to 30V. Its 40mΩ R_DS(on) at 4.5V ensures compatibility with 5V MCU outputs commonly used in body control modules.

What is the maximum continuous drain current at 70°C ambient?

The datasheet specifies 5A continuous drain current at T_A = +70°C on a 1"×1" FR-4 board with 2 oz. copper. This derating reflects thermal limits imposed by the 90°C/W R_θJA and 1.4W P_D rating-not device failure, but safe sustained operation under defined PCB conditions.

Does DMN3033LSNQ-13 have integrated ESD protection?

No. The datasheet does not specify on-chip ESD protection structures. External TVS diodes or series resistors are recommended for gate protection in environments with high static discharge risk, especially in automotive assembly lines or handheld device integration.

Can DMN3033LSNQ-13 be used in parallel configurations?

Yes, but with caution. Its positive temperature coefficient for R_DS(on) (shown in Fig. 6) supports current sharing; however, layout symmetry, individual gate resistors, and thermal coupling must be carefully managed to avoid imbalance-especially above 8A total current.
