Product details
Overview
DMPH3010LK3-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDS, 7.5mΩ RDS(ON) at VGS = -10V, and -50A continuous drain current at TC = +25°C, housed in a TO252 (DPAK) package. It is AEC-Q101 qualified and rated for operation up to +175°C junction temperature, making it suitable for automotive power management and high-temperature DC-DC converter primary-side switching.
For engineers reviewing the DMPH3010LK3-13 datasheet, DMPH3010LK3-13 pinout, DMPH3010LK3-13 application, or DMPH3010LK3-13 equivalent, key selection criteria include its low RDS(ON) at -4.5V gate drive, 100% production-tested UIS capability, and thermal resistance of 1.0°C/W (junction-to-case), critical for thermally constrained automotive and industrial power stages.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance while maintaining fast switching performance-evidenced by 9.0ns turn-on delay, 255ns turn-off delay, and 21.7nC Qgd at VGS = -10V. Its body diode exhibits 27ns reverse recovery time and 21nC QRR under -10A/−100A/μs conditions.
The device is characterized for stable operation across −55°C to +175°C, with RDS(ON) normalized to ≤1.5× nominal at 175°C (VGS = -4.5V). Its 1.0°C/W RθJC enables direct heatsinking via the exposed drain pad, supporting high-power density designs without external thermal vias.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH3010LPSQ-13 | Same die, but in SO-8 package; RθJA = 62°C/W (vs. 38°C/W for TO252); no exposed drain pad | Limited to <2.5W ambient operation; unsuitable for high-current automotive under-hood use | Select only when board space is constrained and thermal budget allows ≥50°C/W total resistance |
| IPB80P03P4L-04 | Infineon OptiMOS P4; -30V, 4.0mΩ @ -10V, but 150°C TJ max and non-AEC-Q101 | Higher efficiency at high current, but not qualified for automotive mission-critical systems | Prefer for industrial power supplies where AEC-Q101 is not required and lower RDS(ON) is prioritized |
Compared with DMTH3010LPSQ-13 and IPB80P03P4L-04, DMPH3010LK3-13 uniquely combines AEC-Q101 qualification, +175°C operation, and TO252 thermal performance-making it the only option for thermally demanding automotive high-side switching where reliability and junction temperature margin are non-negotiable.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMPH3010LK3-13 supports -40A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This reflects a 20% reduction from its -50A rating at 25°C, consistent with its thermal derating curve and 1.0°C/W RθJC.
Is the TO252 package lead-free and RoHS compliant?
Yes-the DMPH3010LK3-13 uses a matte tin finish over copper leadframe and green molding compound, meeting EU RoHS Directive 2011/65/EU and Diodes Incorporated's halogen- and antimony-free "Green" standard (<900ppm Br, <900ppm Cl, <1000ppm Sb).
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to control dV/dt and prevent oscillation-especially given its 139nC total gate charge and 6.2Ω intrinsic gate resistance. Typical values range from 10Ω to 47Ω depending on switching frequency and driver capability, per layout-dependent ringing analysis.
Can DMPH3010LK3-13 be used in linear mode (Ohmic region) operation?
No-it is not characterized or rated for linear (saturation) mode operation. The Safe Operating Area (SOA) chart shows only single-pulse capability down to 10μs, and its RDS(ON) is specified only in enhancement mode; sustained linear operation risks thermal runaway due to positive temperature coefficient behavior.
