Diodes Incorporated DMN3052L-7

Overview

DMN3052L-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in SOT-23 package, rated for 5.4A continuous drain current at 25°C, with R_DS(ON) = 32mΩ @ V_GS = 10V and 42mΩ @ V_GS = 4.5V, designed for low-voltage DC-DC power switches and load switching in space-constrained portable electronics.

For engineers reviewing the DMN3052L-7 datasheet, DMN3052L-7 pinout, DMN3052L-7 application, or DMN3052L-7 equivalent, key selection criteria include gate threshold voltage (0.62–1.2V), thermal resistance (90°C/W), AEC-Q101 qualification, and SOT-23 terminal layout compatibility with high-density PCB routing.

Technical Context

This discrete MOSFET operates as a single N-channel switch with enhancement-mode behavior, requiring positive gate drive relative to source. Its low V_GS(th) enables direct interfacing with 3.3V and 5V logic controllers without level-shifting circuitry.

Dynamic performance is defined by C_iss = 555pF, C_oss = 109pF, and Q_g = 6.3nC at V_GS = 4.5V, supporting fast turn-on/turn-off transitions while maintaining low switching losses in PWM-driven loads.

FAQ

Is DMN3052L-7 suitable for automotive applications?

Yes - it is qualified to AEC-Q101 standards, including temperature cycling, highly accelerated stress testing, and ESD verification. It supports operating temperatures from −55°C to +150°C and is used in body control modules, lighting, and infotainment power rails where reliability and thermal stability are essential.

What is the maximum safe continuous drain current at 85°C ambient?

At T_A = 85°C, the continuous drain current is derated to approximately 3.4A based on thermal resistance (90°C/W) and maximum junction temperature (150°C). This assumes operation on a standard FR-4 PCB with no additional heatsinking or airflow.

Can DMN3052L-7 be used in a high-side configuration?

No - it is optimized as a low-side switch. Using it as a high-side switch would require gate drive ≥30V to ensure full enhancement, exceeding its ±12V V_GS rating. A dedicated high-side driver or P-channel alternative is required for that topology.

Does DMN3052L-7 have integrated ESD protection?

It features inherent gate oxide ESD robustness validated per AEC-Q101, with |I_GSS| ≤800nA at ±19V gate stress. However, no external ESD protection diode is integrated - system-level TVS or RC filtering is recommended for harsh environments like automotive or industrial interfaces.
