Diodes Incorporated DMN5L06T-7

Overview

DMN5L06T-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT-523 package, rated for 50 V V_DSS, 280 mA continuous drain current, and 1.6 Ω R_DS(on) at V_GS = 2.7 V. It features ultra-low gate threshold voltage (0.49–1.2 V), low input capacitance (50 pF C_iss), and fast switching speed-designed for space-constrained load switching in portable power management circuits.

For engineers reviewing the DMN5L06T-7 datasheet, DMN5L06T-7 pinout, DMN5L06T-7 application, or DMN5L06T-7 equivalent, key selection criteria include its low V_GS(th) enabling direct 1.8 V/2.5 V logic-level drive, minimal thermal resistance (833 °C/W), RoHS-compliant "Green" packaging, and suitability for high-density battery-powered systems requiring low quiescent leakage and fast turn-on.

Technical Context

This discrete MOSFET operates in enhancement mode with a single N-channel silicon structure. Its gate threshold voltage range (0.49–1.2 V) ensures reliable turn-on from low-voltage microcontrollers, while the 50 V breakdown rating supports operation across 3.3 V, 5 V, and 12 V rail domains. The device uses a standard planar process with alloy-42 leadframe and matte tin plating.

Thermal performance is defined by FR-4 PCB mounting per AP02001 layout (1" × 0.85"), yielding 150 mW P_D and 833 °C/W R_θJA. Electrical behavior includes low gate leakage (±20 nA at V_GS = ±20 V) and controlled dynamic parameters: C_iss = 50 pF, C_oss = 25 pF, Crss = 5.0 pF at V_DS = 25 V.

FAQ

What is the maximum gate-source voltage rating for DMN5L06T-7?

The DMN5L06T-7 has a continuous gate-source voltage rating of ±20 V and a pulsed rating of ±40 V. Exceeding ±20 V continuously risks oxide layer damage; pulsed operation above this must remain within the absolute maximum ratings table and avoid exceeding total energy limits defined by gate capacitance and pulse width.

Can DMN5L06T-7 be used in reverse conduction (source-to-drain) mode?

Yes-the DMN5L06T-7 contains an intrinsic body diode with V_SD = 0.5–1.4 V at I_S = 115 mA. It supports limited reverse current flow, but sustained reverse conduction increases junction temperature and may exceed P_D limits unless thermally managed per the derating curve in Figure 11.

Is DMN5L06T-7 suitable for PWM motor control at 20 kHz?

It is viable for low-power PWM loads (<280 mA) due to its 50 pF C_iss and fast switching characteristics, but not recommended for continuous motor drive. Thermal limitations (150 mW P_D) and lack of integrated gate driver make it appropriate only for signal-level gating-not high-current inductive loads requiring robust shoot-through immunity.

Does the SOT-523 package support automated optical inspection (AOI) after reflow?

Yes-its standardized footprint, visible top-side marking (K5L YM), and coplanar lead geometry meet IPC-A-610 Class 2 requirements for AOI. The matte tin finish provides consistent reflectivity, and the UL 94V-0 mold compound resists post-reflow discoloration, enabling reliable solder-joint and alignment verification.
