Product details

Overview

DMP3068L-13 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in SOT-23 package, delivering 72 mΩ R_DS(on) at V_GS = −10 V and −3.9 A continuous drain current at T_A = +25°C. It serves as a low-side load switch or reverse-polarity protection device in compact DC/DC converters, USB power switches, and battery-powered systems.

For engineers reviewing the DMP3068L-13 datasheet, DMP3068L-13 pinout, DMP3068L-13 application, or DMP3068L-13 equivalent, key selection criteria include verified R_DS(on) at −4.5 V (85 mΩ), gate threshold voltage range (−0.5 to −1.3 V), thermal resistance (182 °C/W), and SOT-23 terminal layout compatibility with space-constrained PCBs.

Technical Context

This MOSFET uses planar trench-gate technology optimized for low on-resistance while maintaining fast switching speed (t_d(on) = 3.5 ns, t_f = 33.9 ns) and low gate charge (Q_G = 7.3 nC at V_GS = −4.5 V). Its −1.3 V maximum V_GS(th) enables reliable turn-on with 3.3 V logic-level control.

The device integrates a body diode with V_SD = −1.2 V at I_S = −1.0 A and exhibits low output capacitance (C_oss = 57 pF) and reverse transfer capacitance (C_rss = 47 pF), supporting high-frequency synchronous rectification and PWM-driven power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V: Maximum blocking voltage for 12 V and 24 V rail protection applications.
R_DS(on)	72 mΩ @ V_GS = −10 V: Enables ≤0.12 W conduction loss at 3.9 A, critical for thermally constrained designs.
I_D (continuous)	−3.9 A @ T_A = +25°C: Supports medium-power load switching without forced airflow.
Q_G	7.3 nC @ V_GS = −4.5 V: Reduces gate drive power and enables efficient operation with low-current microcontroller GPIOs.
C_iss	708 pF @ V_DS = −15 V: Determines input impedance and gate drive timing in high-speed switching circuits.
R_θJA	182 °C/W (FR-4, min pad): Defines thermal derating curve-limits usable power to ~0.7 W at ambient 50°C.

Pinout & Package

SOT-23 (Standard) surface-mount package with 3 terminals: Drain (D), Gate (G), Source (S). Molded plastic case rated UL 94V-0; weight ≈ 0.006 g. Moisture sensitivity level 1 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
D (Drain)	High-side or low-side power path connection	Connected to input rail in high-side switch; tied to load return in low-side configuration.
G (Gate)	Control electrode	Accepts negative bias relative to source; −1.3 V max V_GS(th) ensures full enhancement with 3.3 V logic.
S (Source)	Reference node for gate drive and current return	Bonded to PCB ground plane in low-side switch; requires stable reference for accurate V_GS control.

Key Features

Feature	Design Value
Low R_DS(on) at −4.5 V	85 mΩ enables 3.3 V MCU-compatible switching with <0.15 W loss at 3.6 A.
Low gate threshold voltage	V_GS(th) down to −0.5 V ensures robust turn-on margin across temperature and process variation.
Fast switching with low Q_G	7.3 nC total gate charge reduces driver stress and minimizes transition losses in 500 kHz+ SMPS.
Low C_rss/C_iss ratio	47 pF / 708 pF = 6.6% supports stable gate drive under high dV/dt conditions without oscillation.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG3415L-7	R_DS(on) = 50 mΩ @ −4.5 V; higher Q_G = 12.5 nC; same SOT-23 package.	Better conduction loss but slower switching; suited for lower-frequency (<200 kHz) load switching.	Select when minimizing I²R loss dominates over switching loss and gate drive capability is sufficient.
SI2301DDS-T1-GE3	R_DS(on) = 115 mΩ @ −4.5 V; lower V_GS(th) = −0.4 V; 1.4× higher C_iss.	Higher on-resistance increases conduction loss; better low-voltage turn-on margin for 1.8 V systems.	Prefer for ultra-low-voltage control interfaces where −0.4 V V_GS(th) guarantees turn-on below 2.0 V.

Compared with DMG3415L-7 and SI2301DDS-T1-GE3, DMP3068L-13 offers balanced performance: lower Q_G than DMG3415L-7 for faster switching, and significantly lower R_DS(on) than SI2301DDS-T1-GE3 for reduced conduction loss in 3.3 V–5 V systems.

FAQ

What is the maximum continuous drain current for DMP3068L-13 at 70°C ambient?

The maximum continuous drain current is −3.2 A at T_A = +70°C with standard FR-4 mounting (Note 6). This derating reflects junction-to-ambient thermal resistance of 103 °C/W under enhanced 2 oz copper layout, ensuring safe operation below T_J(max) = +150°C.

Does DMP3068L-13 support 3.3 V logic-level gate drive?

Yes. With V_GS(th) ranging from −0.5 V to −1.3 V and R_DS(on) = 85 mΩ at V_GS = −4.5 V, it fully enhances using 3.3 V logic referenced to source-no level-shifting required. Gate leakage remains ±100 nA at ±12 V, ensuring low static power.

Is the body diode suitable for reverse recovery in synchronous rectification?

The integrated body diode has V_SD = −1.2 V at I_S = −1.0 A and exhibits soft recovery behavior typical of planar MOSFETs. While not optimized for high-frequency freewheeling like dedicated Schottkys, it supports synchronous rectification up to 1 MHz with appropriate dead-time control.

What is the moisture sensitivity level (MSL) and reflow profile compliance?

DMP3068L-13 is rated MSL Level 1 per J-STD-020, meaning unlimited floor life at ≤30°C/60% RH and compatibility with standard lead-free reflow profiles (peak 260°C). The matte tin finish on Alloy 42 leadframe ensures solderability per MIL-STD-202, Method 208.
