Product details

Overview

DMP3097L-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V V_DSS, 65mΩ R_DS(ON) at V_GS = -10V, and -3.9A continuous drain current at T_A = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters and LED backlighting circuits.

For engineers reviewing the DMP3097L-7 datasheet, DMP3097L-7 pinout, DMP3097L-7 application, or DMP3097L-7 equivalent, key selection criteria include gate threshold voltage (-1.0 to -2.1V), low input capacitance (563pF), fast switching times (t_D(ON) = 10ns), thermal resistance (82°C/W with copper pad), and RoHS-compliant "Green" packaging.

Technical Context

This MOSFET employs planar trench-gate technology optimized for low R_DS(ON) while maintaining controlled gate charge (Q_g = 6.6nC at V_GS = -4.5V) and low Crss (41pF), enabling efficient operation in 3.3V/5V logic-driven power stages. Its negative V_GS(TH) ensures reliable turn-on with standard microcontroller GPIOs.

The device features integrated body diode with V_SD = -0.85V at -2.7A and exhibits stable R_DS(ON) over temperature (±15% variation from -55°C to +150°C at fixed V_GS), supporting robust performance in automotive cabin modules and industrial PMICs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - Withstands reverse-biased drain-source voltage up to 30V without breakdown in high-side or floating-switch configurations.
R_DS(ON)	65mΩ @ V_GS = -10V - Delivers ≤250mW conduction loss at 3.8A, critical for thermally constrained portable power rails.
I_D (continuous)	-3.9A @ T_A = +25°C - Supports sustained load currents in space-limited 1W-class buck regulators and LED drivers.
Q_g	6.6nC @ V_GS = -4.5V - Enables fast, low-energy gate drive with standard 3.3V logic, reducing switching losses below 1MHz.
C_iss	563pF @ V_DS = -25V - Limits Miller-induced shoot-through risk in synchronous rectification and improves EMI margin.
T_J range	-55°C to +150°C - Qualified for under-hood automotive modules and industrial control environments without derating.

Pinout & Package

Package: SOT23 - Surface-mount plastic package with matte tin-plated copper lead-frame, UL 94V-0 rated, moisture sensitivity level 1, weight ≈0.008g.

Low input capacitance	C_iss = 563pF - Reduces gate drive power and improves noise immunity in high-frequency switching nodes.
Fast switching speed	t_D(ON) = 10ns, t_F = 11ns - Minimizes transition losses in 500kHz–1MHz DC-DC topologies.
Thermally enhanced layout support	R_θJA = 82°C/W with 1-inch² copper pad - Enables 1.52W dissipation in compact PCB areas without heatsinks.
Halogen- and antimony-free "Green" construction	<900ppm Br, <900ppm Cl, <1000ppm Sb - Meets IEC 61249-2-21 and automotive OEM environmental requirements.

Applications

LED Backlight Control

USB-C Power Delivery Switch

Use Scenario: Driving white LED strings in thin-profile LCD displays using PWM dimming at 1–20kHz.

IC Role / Device Role / Timing Role: Low-side current sink switch with fast fall time (11ns) to preserve PWM duty cycle fidelity and minimize ghosting.

Use Value: 65mΩ R_DS(ON) limits voltage drop to <120mV at 1.8A, preserving forward voltage headroom for 3–4 LED series stacks.

Use Scenario: Reverse-voltage protection and load switching in USB-C 5V/3A power paths.

IC Role / Device Role / Timing Role: P-channel high-side switch controlled by USB PD controller GPIO, leveraging -2.1V V_GS(TH) for direct 3.3V logic compatibility.

Use Value: Low 99mΩ R_DS(ON) at V_GS = -4.5V ensures <450mV dropout at 3A, meeting USB-C voltage regulation spec.

Industrial Sensor Power Gating

Automotive Cabin Lighting Dimmer

Use Scenario: Enabling/disabling 24V analog sensor supplies in PLC I/O modules during sleep mode.

IC Role / Device Role / Timing Role: Load switch with ultra-low IDSS (<800nA) to prevent leakage-induced bias errors in precision signal chains.

Use Value: -800nA max zero-gate leakage preserves µA-level standby current budgets across 100+ sensor channels.

Use Scenario: PWM-controlled dimming of 12V incandescent or RGB LED cabin lights in passenger vehicles.

IC Role / Device Role / Timing Role: Synchronous rectifier in buck-based constant-current driver, operating at 200–500kHz with 150°C junction rating.

Use Value: Stable R_DS(ON) over -40°C to +125°C ambient enables consistent brightness without thermal compensation circuitry.

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) = 42mΩ @ V_GS = -4.5V; higher Q_g = 11.5nC; same SOT23 package	Better conduction efficiency but slower switching; suited for lower-frequency, high-current loads	Select when minimizing I²R loss dominates over switching loss, e.g., 100kHz buck converters with >4A output.
AO3401	R_DS(ON) = 52mΩ @ V_GS = -4.5V; V_GS(TH) = -0.7 to -1.3V; non-AEC-Q qualified	Lower gate threshold enables weaker drive strength but lacks automotive qualification and tighter parametric spread	Prefer for cost-sensitive consumer electronics where AEC-Q101 compliance and 150°C operation are not required.

Compared with DMG3415L-7 and AO3401, DMP3097L-7 offers balanced trade-off between gate drive simplicity (low V_GS(TH)), switching speed (10ns t_D(ON)), and thermal ruggedness (150°C T_J), making it optimal for space-constrained, medium-frequency power management where reliability and ease of drive matter.

FAQ

What is the maximum safe operating voltage for DMP3097L-7 in blocking mode?

The absolute maximum drain-source voltage is -30V, verified per JEDEC JESD78 testing. Operation beyond this rating risks avalanche breakdown and irreversible damage. For 24V systems, a 20% derating yields -24V max recommended working voltage to ensure long-term reliability under transients.

Can DMP3097L-7 be used in high-side switch configurations?

Yes - as a P-channel MOSFET, it is inherently suited for high-side switching. Gate must be driven 10–15V below the source (e.g., source at 12V, gate at 0–2V) to achieve full enhancement. Its -2.1V max V_GS(TH) allows use with simple resistive or GPIO-based level-shifting networks.

Does DMP3097L-7 meet AEC-Q101 requirements for automotive use?

No - the DMP3097L-7 is not AEC-Q101 qualified. Diodes Incorporated offers the pin-compatible DMP3097LQ-7 variant, which undergoes stress testing per AEC-Q101 Rev D and is manufactured in IATF 16949-certified facilities for automotive applications.

How does thermal performance change when mounted on standard FR-4 versus enhanced copper pad layouts?

R_θJA degrades from 82°C/W (with 1-inch² copper) to 123°C/W (minimum pad layout). At 1.52W dissipation, junction temperature rises by ~51°C on standard layout versus enhanced layout - potentially exceeding 150°C. Use of thermal vias and copper pour is strongly advised for continuous >1W operation.
