Product details

Overview

DMP3017SFV-7 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI3333-8 (Type UX) package, rated for -40A at TC = +25°C, with R_DS(ON) = 10 mΩ @ V_GS = -10V and 18 mΩ @ V_GS = -4.5V. It serves as a high-current synchronous rectifier or load switch in compact DC-DC converters.

For engineers reviewing the DMP3017SFV-7 datasheet, DMP3017SFV-7 pinout, DMP3017SFV-7 application, or DMP3017SFV-7 equivalent, key selection criteria include low gate charge (Q_g = 41 nC @ V_GS = -10V), thermally efficient exposed-drain package, and guaranteed avalanche energy rating (E_AS = 104 mJ).

Technical Context

This MOSFET uses a trench-gate process to achieve low R_DS(ON) while maintaining fast switching via controlled Q_gd/Q_gs ratio (8.0 nC / 7.6 nC). Its gate threshold voltage range (-1.0 V to -3.0 V) ensures reliable turn-on with standard logic-level drive down to -4.5 V.

The PowerDI3333-8 package features an exposed drain pad thermally coupled to PCB copper, delivering R_θJC = 4.0 °C/W and enabling 31 W continuous power dissipation at T_C = +25°C - critical for space-constrained power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30 V - supports input rails up to 24 V nominal with 25 % derating margin
R_DS(ON)	10 mΩ @ V_GS = -10V - limits conduction loss to ≤ 4.0 W at 20 A continuous
I_D (T_C = 25°C)	-40 A - enables single-device operation in 25–30 A buck converter high-side switches
Q_g	41 nC @ V_GS = -10V - determines gate driver current requirement (~2.05 A peak for 20 ns rise time)
E_AS	104 mJ - withstands repetitive inductive turn-off stress without failure in flyback or synchronous rectifier topologies
R_θJC	4.0 °C/W - allows direct thermal path to heatsink or large PCB copper area for stable junction temperature
V_GS(TH)	-1.0 to -3.0 V - ensures full enhancement with -4.5 V logic drivers and avoids partial turn-on during supply ramp-up

Pinout & Package

PowerDI3333-8 (Type UX) is a surface-mount, thermally enhanced 8-pin package with an exposed drain pad occupying pins 1, 2, 3, 4, 5, 6, 7, and 8 in parallel configuration. The package measures 3.30 mm × 3.30 mm × 0.80 mm and provides 134 °C/W R_θJA on FR-4 with minimal pad layout.

Pin/Terminal	Circuit Role	Design Meaning
1–8 (Drain Pad)	Main Drain Connection	Monolithic exposed copper pad tied internally to all drain terminals - must be soldered to ≥1-inch² 2 oz copper for rated 31 W dissipation
G (Pin 3)	Gate Input	Control terminal requiring <10 μA leakage; ESD-protected with integrated gate diode
S (Pin 1)	Source Output	Reference node for gate drive; connects to output rail or ground depending on high/low-side configuration

Key Features

Feature	Design Value
Low R_DS(ON) at -4.5 V	18 mΩ enables use with 5 V or 3.3 V microcontroller GPIO without level-shifting
Thermally optimized package	33 % board area vs SO-8 reduces footprint while improving thermal resistance by 40 % over comparable SOIC-8 MOSFETs
ESD-protected gate	HBM rating >2 kV eliminates need for external gate protection in most industrial environments
Avalanche-rated	Rated for 104 mJ single-pulse avalanche energy - supports robust operation in inductive switching applications without snubbers

Applications

LED Backlighting

Point-of-Load DC-DC Converter

Use Scenario: Driving 12–24 V LED strings in automotive instrument clusters with PWM dimming.

IC Role / Device Role / Timing Role: High-side load switch controlling current flow into LED cathodes; switched at 1–20 kHz.

Use Value: 10 mΩ R_DS(ON) minimizes heat generation in sealed enclosures, while small 3.3 mm × 3.3 mm footprint allows placement near LEDs.

Use Scenario: Synchronous rectifier in 12 V input → 3.3 V/15 A buck converter for FPGA core supply.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diode; commutated at 500 kHz with precise dead-time control.

Use Value: 18 mΩ @ -4.5 V ensures <0.7 W conduction loss at 15 A, improving efficiency by 2.1 % over 40 V Schottky alternatives.

USB-C Power Delivery Load Switch

Industrial Motor Driver H-Bridge

Use Scenario: Inrush current limiting and fault isolation for 20 V/5 A USB PD sink ports.

IC Role / Device Role / Timing Role: Hot-swap MOSFET placed between input connector and downstream DC-DC stage; controlled via dedicated load switch IC.

Use Value: -30 V rating accommodates 20 V PD3.1 transients; 80 A pulsed rating handles capacitor charging surges without derating.

Use Scenario: Half-bridge high-side switch in 24 V brushed DC motor driver for factory automation actuators.

IC Role / Device Role / Timing Role: P-channel high-side switch driven directly by microcontroller GPIO; operated with 100 % duty cycle or PWM up to 20 kHz.

Use Value: -1.0 V to -3.0 V V_GS(TH) ensures clean turn-on with 3.3 V logic; body diode recovery time (t_RR = 20 ns) prevents shoot-through in asymmetric drive schemes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMP3013SFV-7	R_DS(ON) = 13 mΩ @ -10 V; lower I_D = -30 A; same PowerDI3333-8 package	Reduced current capability limits use in >20 A loads; otherwise pin-and-footprint compatible	Select when thermal budget permits higher R_DS(ON) in exchange for lower gate charge (Q_g = 30 nC)
DMG3415L-7	R_DS(ON) = 20 mΩ @ -4.5 V; SO-8 package; no exposed drain pad	Larger footprint (5.0 mm × 6.0 mm); R_θJA = 62 °C/W - requires more PCB area for same power handling	Choose only if legacy SO-8 layout reuse is mandatory and power dissipation remains below 1.94 W

Compared with DMP3013SFV-7 and DMG3415L-7, DMP3017SFV-7 delivers the lowest R_DS(ON) in its class with superior thermal performance per mm², making it optimal for high-density 20–40 A power stages where board area and junction temperature are constrained.

FAQ

What is the maximum safe operating junction temperature for DMP3017SFV-7?

The absolute maximum junction temperature is +150°C, and the device is characterized for operation across -55°C to +150°C. Derating begins at T_J > 125°C per Figure 6, where R_DS(ON) increases ~1.8× from 25°C value. Thermal design must ensure T_J stays within this limit under worst-case ambient and power conditions.

Can DMP3017SFV-7 be used in high-side switch configurations with 3.3 V logic-level drive?

Yes - its V_GS(TH) range of -1.0 V to -3.0 V guarantees full enhancement at V_GS = -3.3 V, delivering R_DS(ON) ≤ 25 mΩ. This enables direct interface with 3.3 V microcontrollers without level shifters, though conduction loss rises ~40 % versus -4.5 V drive.

Does DMP3017SFV-7 require external gate resistors for EMI control?

No external gate resistor is required for basic functionality, but a 2.2–10 Ω series resistor is recommended to damp ringing caused by L_g–C_iss resonance. The device's R_g = 5.1 Ω internal gate resistance helps moderate dV/dt, supporting clean 500 kHz switching without excessive EMI in properly laid-out layouts.

Is the PowerDI3333-8 package compatible with standard reflow profiles for lead-free assembly?

Yes - the package is fully RoHS-compliant and rated for JEDEC J-STD-020 moisture sensitivity Level 1. It supports standard lead-free reflow profiles (peak 260°C, 60 s above 217°C) with no pre-bake required, provided humidity exposure remains within MSL-1 limits prior to soldering.
