Product details

Overview

DMP3097L-13 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 +25°C. It delivers low gate threshold voltage (-1.0 to -2.1V), fast switching (t_D(ON) = 10ns), and low input capacitance (C_iss = 563pF), enabling high-efficiency operation in compact DC-DC converters and LED backlighting circuits.

For engineers reviewing the DMP3097L-13 datasheet, DMP3097L-13 pinout, DMP3097L-13 application, or DMP3097L-13 equivalent, key selection criteria include verified R_DS(ON) at -4.5V (99mΩ), thermal resistance (R_θJA = 123°C/W on FR-4), SOA compliance up to 150°C junction temperature, and SOT23 footprint compatibility with space-constrained power stages.

Technical Context

This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters and boost regulators. Its P-channel architecture eliminates external level-shifting circuitry, while the -2.1V maximum V_GS(TH) ensures reliable turn-on with standard 3.3V/5V logic-level gate drive.

The device features a fully characterized body diode (V_SD = -0.85V at -2.7A) and low Crss (41pF), minimizing Miller-induced shoot-through risk during hard-switching. Thermal performance is validated under two PCB conditions: 123°C/W (minimum pad) and 82°C/W (1-inch² copper plate), supporting design margining for ambient temperatures up to +70°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - Maximum blocking voltage before avalanche conduction in high-side switch configurations
R_DS(ON)	65mΩ @ V_GS = -10V - Confirmed on-resistance enabling ≤0.25W conduction loss at 2A load current
I_D (max)	-3.9A @ T_A = +25°C - Continuous current rating defining safe operating area for 1W power dissipation
V_GS(TH)	-1.0 to -2.1V - Gate threshold range ensuring full enhancement with 3.3V microcontroller outputs
C_iss	563pF - Input capacitance determining gate drive energy requirement (Q_g = 6.6nC at -4.5V)
R_θJA	123°C/W - Junction-to-ambient thermal resistance on standard FR-4 board, limiting max ambient to +70°C at full load
t_D(ON)	10ns - Turn-on delay time critical for PWM frequencies above 1MHz in high-frequency DC-DC designs

Applications

LED Backlight Control

USB Power Switch

Use Scenario: Driving white LED strings in portable displays using PWM dimming at 1–5kHz.

IC Role / Device Role / Timing Role: High-side current switch controlling LED anode connection to V_IN; synchronously modulated by MCU PWM signal.

Use Value: 65mΩ R_DS(ON) limits conduction loss to <0.26W at 2A, preserving battery runtime; fast t_F = 11ns prevents LED current overshoot during dimming transitions.

Use Scenario: Enabling/disabling 5V USB VBUS power to peripheral devices in host controllers.

IC Role / Device Role / Timing Role: Load switch isolating downstream ports; controlled by USB enumeration logic or system PMIC.

Use Value: -2.1V V_GS(TH) ensures full turn-on with 3.3V GPIO; low IDSS (<800nA) prevents standby leakage that would violate USB suspend current limits.

DC-DC Synchronous Rectifier

Industrial Sensor Bias Supply

Use Scenario: Replacing Schottky diode in buck converter output stage for improved efficiency at 12V→3.3V conversion.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier commutated by controller's complementary gate signal; body diode conducts during dead time.

Use Value: 99mΩ R_DS(ON) at -4.5V reduces conduction loss by 65% vs. 0.4V Schottky; C_oss = 48pF minimizes reverse recovery energy loss.

Use Scenario: Providing regulated 5V bias to analog sensor front-ends in factory automation modules.

IC Role / Device Role / Timing Role: Pass element in linear post-regulator stage following switching converter; configured as source-follower for ripple rejection.

Use Value: 1.52W PD rating supports 300mA at 5V with 123°C/W thermal resistance; low V_GS(TH) tolerance ensures stable regulation across -40°C to +85°C industrial temperature range.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3026LFD-7	R_DS(ON) = 42mΩ @ -10V but higher Q_g (12.5nC); SOT23-3L package with same pinout	Better conduction loss at high gate drive, but increased gate drive power and slower switching (t_D(ON) = 14ns)	Select when efficiency at >3A load dominates over switching frequency or gate drive capability constraints
AO3401	R_DS(ON) = 85mΩ @ -4.5V; higher V_GS(TH) (-0.7 to -1.3V); identical SOT23 footprint	Marginally higher conduction loss and narrower gate drive margin; lower cost in high-volume procurement	Select for cost-sensitive consumer applications where 3.3V logic margin is sufficient and 100mΩ R_DS(ON) is acceptable

Compared with DMN3026LFD-7 and AO3401, DMP3097L-13 offers optimal balance of low R_DS(ON) at -4.5V (99mΩ), minimal gate charge (6.6nC), and tight V_GS(TH) distribution (-1.0 to -2.1V), making it preferred for space-constrained, medium-current DC-DC and load-switching designs requiring predictable turn-on behavior across temperature.

FAQ

What is the maximum continuous drain current for DMP3097L-13 at +70°C ambient?

The maximum continuous drain current is -3.1A at T_A = +70°C, as specified in the Absolute Maximum Ratings table. This derating accounts for thermal limitations on standard FR-4 PCBs with minimum pad layout (R_θJA = 123°C/W). At higher ambient temperatures or with enhanced copper heatsinking, current must be further reduced per the SOA curve in Figure 12.

Does DMP3097L-13 support gate drive from a 1.8V microcontroller I/O?

No - the guaranteed V_GS(TH) range is -1.0V to -2.1V, meaning full enhancement requires |V_GS| ≥ 2.1V. A 1.8V I/O cannot reliably turn the device fully on; 3.3V or higher gate drive is recommended. For 1.8V systems, consider alternatives with lower |V_GS(TH)| such as DMG2305UVT.

Is the SOT23 package of DMP3097L-13 compatible with automated optical inspection (AOI) after reflow?

Yes - the SOT23 package uses matte tin annealed terminals with defined coplanarity (≤0.1mm) and solderable per MIL-STD-202 Method 208. Its standardized dimensions (2.4mm × 1.3mm × 0.915mm) and visible top-side marking (D98/YM) enable reliable AOI detection of solder joint integrity and placement accuracy in high-volume SMT lines.

Can DMP3097L-13 be used in automotive applications?

Not as qualified - the DMP3097L-13 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., DMP3097LQ-7) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. For automotive use, contact Diodes' automotive sales team to obtain the qualified version and associated change control documentation.
