Product details

Overview

DMTH10H015LK3-13 from Diodes Incorporated is a 100V, N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for continuous drain current up to 52.5A at TC = +25°C, with R_DS(ON) of 15mΩ @ V_GS = 10V and qualified to AEC-Q101 for automotive-grade reliability. It operates up to +175°C junction temperature and supports high-efficiency DC-DC converters and backlighting power stages.

For engineers reviewing the DMTH10H015LK3-13 datasheet, DMTH10H015LK3-13 pinout, DMTH10H015LK3-13 application, or DMTH10H015LK3-13 equivalent, key selection criteria include its 100V V_DSS, low 15mΩ on-resistance at 10V gate drive, 33.3nC total gate charge, 100% unclamped inductive switching rating, and thermal resistance of 2°C/W (junction-to-case).

Technical Context

This MOSFET employs planar silicon process technology optimized for low R_DS(ON) and fast switching in high-current, high-temperature power conversion topologies. Its gate threshold voltage range (1.4–3.5V) enables compatibility with standard 3.3V/5V/10V logic-level drivers, while its 100% UIS-rated ruggedness ensures robust operation under inductive load transients.

The device features a thermally enhanced DPAK package with direct die-to-case thermal path (R_θJC = 2°C/W), enabling high-power dissipation in compact layouts. Its dynamic parameters-including C_iss = 1871pF, Q_G = 33.3nC, and t_F = 8.1ns-support efficient hard-switched and synchronous rectifier applications up to several hundred kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100V - Supports input rails up to 80V DC-DC converters with margin for voltage spikes
R_DS(ON)	15mΩ @ V_GS = 10V - Enables <1.5W conduction loss at 40A, critical for thermal management
I_D (continuous)	52.5A @ T_C = +25°C - Sustains high output current in buck converter high-side switches
Q_G	33.3nC - Determines gate driver power requirement and switching speed trade-off
T_J max	+175°C - Allows operation in under-hood automotive or industrial enclosures without derating
R_θJC	2°C/W - Enables direct heatsinking to PCB copper or external metal, reducing thermal bottleneck

FAQ

What is the maximum safe operating temperature for DMTH10H015LK3-13?

The device is rated for junction temperatures from –55°C to +175°C, with guaranteed electrical performance across this full range. Thermal design must ensure T_J does not exceed +175°C under worst-case ambient and power dissipation conditions, using R_θJC = 2°C/W and appropriate PCB copper area per datasheet layout guidelines.

Can DMTH10H015LK3-13 be driven directly by a 3.3V microcontroller GPIO?

No-its gate threshold voltage ranges from 1.4V to 3.5V, but R_DS(ON) is only specified at V_GS = 4.5V, 6V, and 10V. At 3.3V, R_DS(ON) exceeds 30mΩ (estimated), causing excessive conduction loss. A dedicated gate driver or level shifter is required for reliable switching.

Is the exposed drain pad electrically isolated from other pins?

No-the exposed pad is internally connected to the drain terminal and must be soldered to a PCB copper pour designated as the drain net. It serves both thermal conduction and electrical connection; isolation would compromise thermal performance and violate the device's mechanical design.

Does DMTH10H015LK3-13 include integrated body diode recovery optimization?

Yes-the datasheet specifies reverse recovery time t_RR = 37.9ns and Q_RR = 51.9nC at IF = 10A and di/dt = 100A/µs, indicating optimized body diode characteristics for synchronous rectification and freewheeling in buck and flyback topologies.
