Diodes Incorporated DMN10H700S-13

Overview

DMN10H700S-13 from Diodes Incorporated is a 100V N-channel enhancement-mode MOSFET in SOT23 package, delivering 700mΩ R_DS(ON) at V_GS = 10V and 0.70A continuous drain current at 25°C. It features low gate threshold voltage (2.0–4.0V), fast switching (t_D(ON) = 2.5ns), and AEC-Q101 qualification for high-reliability power management in space-constrained DC-DC converters.

For engineers reviewing the DMN10H700S-13 datasheet, DMN10H700S-13 pinout, DMN10H700S-13 application, or DMN10H700S-13 equivalent, this page provides verified electrical parameters, thermal behavior under pulsed operation, junction-to-ambient resistance (303°C/W), body diode conduction capability (0.6A), and real-world design implications of its 235pF input capacitance and 4.6nC total gate charge.

Technical Context

This MOSFET operates as a low-side switch with enhancement-mode logic-level gate drive compatibility, supporting direct interface to 3.3V/5V microcontrollers. Its 100V V_DSS rating enables use in buck converters up to 48V input rails, while its 0.4W steady-state power dissipation limits continuous operation to ≤0.56A at 70°C ambient without heatsinking.

The device integrates a monolithic body diode with 0.9–1.1V forward voltage at 1.5A, enabling synchronous rectification or freewheeling in flyback and boost topologies. Its 88°C/W junction-to-case thermal resistance confirms suitability for PCB-mounted thermal relief via copper pour under the drain pad.

FAQ

What is the maximum safe operating temperature for DMN10H700S-13 in continuous conduction mode?

The junction temperature must not exceed +150°C. With R_θJA = 303°C/W and P_D = 0.4W (steady state), the maximum ambient temperature is +30°C without additional copper cooling. Using a 1-inch square 2oz copper pad (R_θJA = 239°C/W), ambient can reach +50°C at full 0.4W dissipation.

Can DMN10H700S-13 be used as a high-side switch?

No-it is optimized as a low-side switch. The SOT23 package lacks isolated source connection required for high-side bootstrap or floating gate drive. Its gate threshold and R_DS(ON) are specified relative to source, making high-side implementation impractical without external level-shifting circuitry.

Does the body diode support reverse recovery in synchronous rectification?

Yes-the body diode has t_RR = 22ns and Q_RR = 15nC at 100V/1.8A, enabling use in discontinuous conduction mode (DCM) flyback or boost converters. However, its 0.9–1.1V V_SD is higher than Schottky alternatives, so efficiency gains are most pronounced above 100kHz switching frequencies.

Is the DMN10H700S-13 compatible with lead-free reflow profiles?

Yes-its lead-free matte tin finish and JEDEC-compliant SOT23 package meet IPC/JEDEC J-STD-020 moisture sensitivity level 1. Standard Pb-free reflow peak temperature (260°C) and dwell time (≤60 seconds) are fully supported without delamination or solder joint integrity issues.
