Product details

Overview

DMPH4016SK3Q-13 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, qualified to AEC-Q101 and rated for operation up to +175°C junction temperature. It is designed for high-reliability automotive power-management functions including DC-DC converters and analog switches.

For engineers reviewing the DMPH4016SK3Q-13 datasheet, DMPH4016SK3Q-13 pinout, DMPH4016SK3Q-13 application, or DMPH4016SK3Q-13 equivalent, key selection criteria include its -40V breakdown voltage, low on-resistance at -4.5V gate drive (15 mΩ), 100% production-tested UIS capability, TO252 package thermal performance (R_θJC = 1.1 °C/W), and AEC-Q101 qualification status.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage range (-1.5 V to -2.5 V) ensures robust turn-on margin under supply variation and temperature extremes.

The device integrates an intrinsic body diode with V_SD = -0.7 V typical at -1 A, supporting synchronous rectification and bidirectional current handling in half-bridge configurations. Its C_iss = 5697 pF and Q_g = 112 nC @ V_GS = -10V define gate-drive energy requirements for efficient PWM control in 48V/12V DC-DC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-40 V - Maximum drain-source blocking voltage for 12V/48V automotive rail protection and switching
R_DS(ON) @ V_GS = -10V	11 mΩ - Enables ≤0.88 W conduction loss at -80A, critical for thermally constrained engine-bay modules
R_DS(ON) @ V_GS = -4.5V	15 mΩ - Supports logic-level gate drive from 5V microcontrollers without level-shifting circuitry
T_J max	+175°C - Allows placement near heat sources (e.g., power inductors, engines) without derating
Q_g @ V_GS = -10V	112 nC - Determines gate-driver peak current requirement (~2.2 A for 50 ns rise time)
E_AS	392 mJ - Specifies single-pulse avalanche energy handling for inductive load switching reliability
R_θJC	1.1 °C/W - Enables direct heatsinking via exposed drain pad for >100 W power dissipation capability

Pinout & Package

Package: TO252 (DPAK), surface-mount, with exposed drain pad for thermal and electrical connection. Molded plastic housing rated UL 94V-0; matte tin-plated copper leadframe.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Reference node for gate drive; connects to high-side switch return path or ground-referenced load
Pin 2 (Gate)	Control input	Receives negative gate voltage relative to source to enable conduction; requires <112 nC charge for full turn-on
Pin 3 (Drain)	Power output / high-side switch node	Exposed metal pad - electrically and thermally connected to drain; must be soldered to PCB copper pour for thermal management

Key Features

Feature	Design Value
AEC-Q101 qualified + PPAP capable	Meets automotive qualification for use in safety-critical power systems with documented change control and traceable manufacturing
100% production UIS tested	Each unit validated for unclamped inductive switching stress, eliminating need for external snubbers in relay/buzzer drivers
Low R_DS(ON) at -4.5V	15 mΩ enables direct interface with 5V logic controllers in battery disconnect and load-switch applications
+175°C operating rating	Supports placement in under-hood ECUs without thermal derating, reducing system-level heatsink size and cost
Halogen- and antimony-free "Green" construction	Complies with automotive environmental standards (Br+Cl <1500 ppm, Sb <1000 ppm) and RoHS 3

Applications

Automotive Battery Disconnect Switch

48V–12V DC-DC Converter High-Side Switch

Use Scenario: Isolating 12V battery during vehicle start-stop cycles or fault conditions to prevent parasitic drain.

IC Role / Device Role / Timing Role: High-side P-channel MOSFET controlling main battery path; operates in static on/off mode with slow switching (<1 Hz).

Use Value: 11 mΩ R_DS(ON) limits voltage drop to ≤0.88 V at 80A, preserving cranking voltage; +175°C rating ensures reliability near engine compartment heat sources.

Use Scenario: High-side synchronous rectifier in buck-derived 48V-to-12V conversion for ADAS domain controllers.

IC Role / Device Role / Timing Role: Power switch in high-frequency (200–500 kHz) PWM stage; driven by gate driver with precise timing control.

Use Value: 112 nC total gate charge and 146 ns t_D(OFF) support efficient high-frequency operation; R_θJC = 1.1 °C/W enables direct heatsinking to PCB for >100 W dissipation.

Engine Control Unit (ECU) Power Management

Automotive Analog Signal Switching

Use Scenario: Supply regulation and load switching for fuel injector drivers, solenoid actuators, and sensor bias rails within ECU modules.

IC Role / Device Role / Timing Role: Low-duty-cycle power switch managing intermittent loads; subjected to repetitive avalanche stress during inductive turn-off.

Use Value: 392 mJ E_AS and 100% UIS testing ensure robustness against inductive kickback without external clamping diodes.

Use Scenario: Bidirectional analog signal routing in automotive infotainment audio paths or sensor multiplexing (e.g., temperature, pressure).

IC Role / Device Role / Timing Role: Low-distortion analog switch; operated with V_GS = 0 V (off) or -4.5 V (on) to minimize on-resistance variation across signal swing.

Use Value: 15 mΩ R_DS(ON) at -4.5V provides flat, low-insertion-loss switching; body diode V_SD = -0.7 V supports reverse current flow in AC-coupled paths.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMTH4007LPSQ-13	-40V V_DSS, 7.5 mΩ @ -10V, TO263 package, R_θJC = 0.8 °C/W	Higher thermal performance but larger footprint; requires different PCB layout and heatsink interface	Select when >136 W power dissipation is required and board space permits TO263 mounting.
IPB80P04P4L-02	-40V V_DSS, 8.0 mΩ @ -10V, TO263, AEC-Q101 qualified, higher Q_g (150 nC)	Lower R_DS(ON) but slower switching; less suitable for >300 kHz DC-DC topologies	Prefer for static switching applications where lowest conduction loss dominates over switching loss.

Compared with DMTH4007LPSQ-13 and IPB80P04P4L-02, DMPH4016SK3Q-13 offers optimal balance of low gate charge (112 nC), TO252-compatible footprint, and verified 175°C operation-making it ideal for space-constrained, high-frequency automotive power stages where thermal interface simplicity matters.

FAQ

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

The DMPH4016SK3Q-13 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's junction-to-case path (R_θJC = 1.1 °C/W) and must be validated against actual PCB copper area and ambient conditions.

Is the body diode suitable for reverse-current freewheeling in synchronous rectification?

Yes-the intrinsic body diode has V_SD = -0.7 V typical at -1 A and t_RR = 27 ns, enabling efficient reverse-current conduction in buck converter low-side operation. Its Q_RR = 22 nC minimizes recovery losses when paired with appropriate gate timing.

Does this part require a negative gate drive voltage relative to source?

Yes-this is a P-channel enhancement-mode MOSFET. Full enhancement requires V_GS ≤ -4.5 V (minimum -10 V for rated R_DS(ON)). Gate drive must be referenced to the source terminal, not ground; level-shifting or isolated gate drivers are needed in high-side configurations.

How is moisture sensitivity classified, and what reflow profile should be used?

The DMPH4016SK3Q-13 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and does not require baking before standard Pb-free reflow. Use Diodes' recommended profile: peak 260°C, 20–40 sec above 217°C, ramp rate ≤3°C/s.
