Product details

Overview

DMP3099LQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V V_DSS, 65 mΩ R_DS(ON) at V_GS = -10 V, and -3.8 A continuous drain current at T_A = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power management functions including backlighting and DC-DC converters.

For engineers reviewing the DMP3099LQ-13 datasheet, DMP3099LQ-13 pinout, DMP3099LQ-13 application, or DMP3099LQ-13 equivalent, key selection criteria include gate threshold voltage (-1.0 to -2.1 V), low input capacitance (563 pF C_iss), fast switching (4.8 ns t_D(ON)), thermal resistance (115 °C/W R_θJA), and SOT23 package compatibility with high-reliability automotive PCB layouts.

Technical Context

This MOSFET operates as a high-side load switch in automotive power rails, leveraging its negative gate threshold and low R_DS(ON) to minimize conduction loss in 12 V systems. Its -30 V V_DSS rating supports transient overvoltage tolerance up to ISO 7637-2 Pulse 1/2a, and its 10.3 Ω gate resistance enables controlled turn-on/turn-off without external gate resistors in many designs.

The device integrates a body diode with -1.26 V forward voltage at -2.7 A, enabling synchronous rectification or freewheeling in buck converters. Its 10.2 mJ avalanche energy (E_AS) and 14.3 A I_AS support robust operation under inductive switching stress common in automotive solenoid and motor control circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30 V - Withstands reverse-biased drain-source transients up to automotive load-dump conditions
R_DS(ON)	65 mΩ @ V_GS = -10 V - Enables ≤0.25 W conduction loss at 2 A continuous load
I_D (max)	-3.8 A @ T_A = +25°C - Supports typical automotive LED backlight strings or small-signal power switches
C_iss	563 pF - Low input capacitance reduces gate drive power and speeds switching in 100–500 kHz DC-DC stages
t_D(ON)	4.8 ns - Enables precise timing control in high-frequency PWM-driven power paths
R_θJA	115 °C/W - Requires minimal copper area (0.5 in² 2 oz) for thermal compliance in sealed automotive enclosures
V_GS(TH)	-1.0 to -2.1 V - Compatible with 3.3 V and 5 V logic-level gate drivers without level shifting

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG3415L-7	R_DS(ON) = 45 mΩ @ V_GS = -4.5 V; higher ID max (-4.5 A); same SOT23 package	Better conduction efficiency at lower gate drive; suited for higher-current 12 V loads	Select when lower R_DS(ON) at 4.5 V drive is required and thermal margin allows higher power dissipation
AO3401	R_DS(ON) = 52 mΩ @ V_GS = -4.5 V; not AEC-Q101 qualified; similar C_iss (570 pF)	Cost-optimized alternative for non-automotive industrial or consumer use only	Use only in non-automotive applications where AEC-Q101 compliance and PPAP are not mandated

Compared with DMG3415L-7 and AO3401, DMP3099LQ-13 offers verified AEC-Q101 qualification and tighter V_GS(TH) distribution for deterministic gate drive in safety-critical automotive subsystems, while maintaining competitive R_DS(ON) and switching performance in SOT23 footprint.

FAQ

Is DMP3099LQ-13 suitable for hot-swap applications?

Yes - its -30 V V_DSS, 14.3 A I_AS, and 10.2 mJ E_AS provide robust transient handling during live insertion. The device's low R_DS(ON) and fast switching also limit inrush current spikes. However, external current limiting or soft-start circuitry is recommended for sustained hot-swap duty cycles above 1 A.

What is the maximum allowable gate-source voltage for DMP3099LQ-13?

The absolute maximum V_GS is ±20 V per the datasheet. Operation beyond ±12 V is not recommended for long-term reliability, and gate drive circuits should clamp at ±15 V to prevent oxide stress. The device's V_GS(TH) range (-1.0 to -2.1 V) ensures reliable turn-on with standard 3.3 V or 5 V logic-level drivers.

Does DMP3099LQ-13 require a gate resistor in typical automotive applications?

A gate resistor is not strictly required due to the device's internal 10.3 Ω gate resistance, which dampens ringing and controls dV/dt. However, a 10–47 Ω external resistor is recommended when driving from high-speed controllers to fine-tune rise/fall times and suppress EMI in sensitive infotainment or ADAS subsystems.

How does the SOT23 package affect thermal performance in enclosed automotive modules?

With R_θJA = 115 °C/W on 0.5 in² 2 oz copper, the SOT23 limits power dissipation to ~0.94 W at 85°C ambient. For sustained >0.5 W loads, thermal vias under the pad and connection to inner-layer ground planes are essential. Derating to -2.9 A at T_A = +70°C reflects this constraint, making it ideal for intermittent or low-duty-cycle automotive loads.
