Product details

Overview

DMPH4016SK3 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V V_DSS, 11 mΩ R_DS(ON) @ V_GS = -10V, and -80A continuous drain current at T_C = +25°C, operating up to +175°C junction temperature. It serves as a high-current, low-loss power switch in synchronous rectification and load switching circuits.

For engineers reviewing the DMPH4016SK3 datasheet, DMPH4016SK3 pinout, DMPH4016SK3 application, or DMPH4016SK3 equivalent, key selection criteria include its 1.1 °C/W R_θJC, 100% production-tested UIS capability, -1.5 to -2.5 V gate threshold, and TO252 (DPAK) thermal pad layout compatibility.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while preserving fast switching performance: t_D(ON) = 11.5 ns, t_F = 165 ns, and Q_gd = 18 nC at V_GS = -10V. Its body diode exhibits V_SD = -0.7 V @ I_S = -1 A and t_RR = 27 ns under defined di/dt conditions.

Thermal design is enabled by direct thermal conduction through the exposed drain pad: R_θJC = 1.1 °C/W and R_θJA = 31 °C/W on FR-4 with 2 oz copper. The device sustains 392 mJ single-pulse avalanche energy (E_AS) with L = 1 mH, validated per production UIS test.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-40 V - Maximum blocking voltage before avalanche onset; defines safe DC-DC input/output rail separation
R_DS(ON)	11 mΩ @ V_GS = -10V - Enables <1.1 W conduction loss at 10 A; critical for high-efficiency buck converter low-side switches
I_D (T_C = +25°C)	-80 A - Continuous current rating with heatsink; supports high-power industrial motor drivers and server VRMs
T_J Range	-55°C to +175°C - Extended thermal envelope allows operation in under-hood automotive or sealed industrial enclosures
Q_g	112 nC @ V_GS = -10V - Gate drive energy requirement determines driver IC selection and switching loss budget
E_AS	392 mJ - Single-pulse avalanche robustness enables reliable operation during inductive load turn-off transients
R_θJC	1.1 °C/W - Thermal resistance from junction to case enables accurate heatsink sizing when mounted on copper thermal pad

Pinout & Package

Package: TO252 (DPAK), surface-mount, thermally enhanced with exposed drain pad occupying the full bottom footprint. Molded plastic housing meets UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Primary current return path; connects to ground or low-side reference; electrically tied to gate driver return
Pin 2 (Gate)	Control input	High-impedance MOSFET control node; requires ≤±20 V drive; R_g = 7 Ω internal gate resistance affects switching speed
Pin 3 (Drain)	Power output / high-side switch node	Exposed metal pad on underside; carries full load current and dissipates heat directly to PCB copper

Key Features

Feature	Design Value
+175°C rated junction temperature	Enables deployment in engine control units, industrial inverters, and sealed power supplies without derating at ambient >125°C
100% production UIS tested	Guarantees avalanche ruggedness across all shipped units-no statistical sampling; eliminates field failure risk from inductive kickback
Low R_DS(ON) × Q_g product	11 mΩ × 112 nC = 1.23 Ω·nC - Balances conduction and switching losses for high-frequency (>500 kHz) DC-DC converters
Matte tin finish, lead-free	RoHS 3 compliant (Br+Cl <1500 ppm, Sb <1000 ppm); solderable per MIL-STD-202 Method 208; compatible with standard reflow profiles
Fast body diode recovery	t_RR = 27 ns, Q_RR = 22 nC - Reduces reverse recovery loss in synchronous rectifier applications and bidirectional power stages

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel high-current power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMTH4007LPS-13	R_DS(ON) = 7.5 mΩ @ -10 V but rated only to +150°C; lower Q_g (75 nC); TO263 package	Better conduction loss at high current, but limited thermal headroom in sealed enclosures	Select when peak ambient <130°C and PCB space allows larger TO263 footprint
IPB80P04P4L-04	R_DS(ON) = 4.0 mΩ @ -10 V; AEC-Q101 qualified; TO263; higher Q_g (160 nC)	Automotive-qualified with PPAP support; higher gate drive demand increases driver loss	Select for automotive OEM programs requiring AEC-Q101 compliance and change control

Compared with DMTH4007LPS-13 and IPB80P04P4L-04, DMPH4016SK3 uniquely balances +175°C operation, 11 mΩ R_DS(ON), and TO252 manufacturability-making it optimal for industrial power modules where thermal margin and assembly yield are prioritized over absolute lowest R_DS(ON).

FAQ

What is the maximum continuous drain current at T_C = +100°C?

The DMPH4016SK3 supports -55 A continuous drain current at case temperature +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO252 package and must be applied when heatsinking is insufficient to maintain T_C ≤ +25°C under full load.

Is the body diode suitable for synchronous rectification?

Yes-the body diode has t_RR = 27 ns and Q_RR = 22 nC at I_F = -9.8 A and di/dt = -100 A/µs, enabling use in synchronous rectifier topologies up to 1 MHz. However, external Schottky diodes may still be preferred for ultra-low forward voltage requirements below 0.5 V.

Does this MOSFET require a gate driver for 3.3 V logic control?

No-its V_GS(TH) range is -1.5 V to -2.5 V, so it fully enhances with -3.3 V gate drive. However, achieving 11 mΩ R_DS(ON) requires V_GS ≤ -10 V; for optimal conduction loss, a dedicated negative gate driver or charge pump is recommended.

What is the meaning of "100% UIS tested" in production?

Every unit undergoes unclamped inductive switching stress at I_AS = -28 A and L = 1 mH, verifying 392 mJ avalanche energy capability. This is not a sample test-it guarantees avalanche ruggedness across the entire production lot, eliminating latent field failures from transient overvoltage events.
