Product details

Overview

DMP3165L-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V V_DSS, 90mΩ R_DS(ON) @ V_GS = -10V, and -3.3A continuous drain current at T_A = +25°C. It delivers low gate threshold (-1.3V to -2.1V), fast switching (t_D(ON) = 3.7ns), and low input capacitance (C_iss = 300pF), enabling high-efficiency power management in compact DC-DC converters.

For engineers reviewing the DMP3165L-13 datasheet, DMP3165L-13 pinout, DMP3165L-13 application, or DMP3165L-13 equivalent, key selection criteria include verified R_DS(ON) at -4.5V (-134mΩ), thermal resistance (R_θJA = 159°C/W on FR-4), diode forward voltage (V_SD = -0.83V), gate charge (Q_g = 1.0nC @ -4.5V), and RoHS-compliant green packaging.

Technical Context

This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters, leveraging its negative gate threshold and low R_DS(ON) to minimize conduction loss. Its 300pF input capacitance and 12.5Ω gate resistance support stable gate drive with minimal ringing under typical 6Ω source impedance.

The device features integrated body diode with reverse recovery time t_RR = 6.5ns and Q_RR = 1.2nC, enabling efficient freewheeling in discontinuous conduction mode. Junction temperature range of -55°C to +150°C and normalized R_DS(ON) variation ≤1.8× over that range ensure robust operation across industrial ambient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - Maximum blocking voltage before avalanche breakdown; defines safe operating range in 24V rail applications.
R_DS(ON)	90mΩ @ V_GS = -10V - Confirmed conduction loss of 1.0mW per mA² at full rated current; enables <1W dissipation at 3.3A.
I_D	-3.3A @ T_A = +25°C - Continuous DC current capability with standard PCB layout; derates to -2.7A at +70°C ambient.
V_GS(TH)	-1.3V to -2.1V - Ensures reliable turn-on with logic-level gate drivers (e.g., 3.3V GPIO) without requiring level-shifting circuitry.
C_iss	300pF @ V_DS = -10V - Low input capacitance reduces gate drive power and speeds up switching transitions in high-frequency (>1MHz) converters.
t_RR	6.5ns - Fast body diode recovery minimizes shoot-through risk and switching loss during dead-time intervals.
P_D	0.8W @ T_A = +25°C - Power dissipation limit on standard FR-4 board; corresponds to ~240°C/W junction-to-ambient rise at full I_D.

Pinout & Package

Package: SOT23 - Surface-mount plastic package measuring 2.9mm × 1.3mm × 1.0mm (L × W × H), with matte tin–annealed copper leadframe, UL 94V-0 rated molding compound, and moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Current return path for channel conduction; tied to system ground or higher potential in high-side configuration	Primary thermal and current path; connects directly to PCB copper pour for heat dissipation and low-inductance return.
Pin 2 (Gate)	Control electrode for channel modulation	High-impedance input requiring <80nA leakage; sensitive to ESD; must be driven with clean, low-impedance signal to avoid oscillation.
Pin 3 (Drain)	Main current output terminal; connected to load or power rail	Exposed drain pad in top view (D-G-S pinout); carries full switched current; requires adequate trace width and thermal relief.

Key Features

Feature	Design Value
Low R_DS(ON) at -4.5V	134mΩ - Enables use with 5V or 3.3V logic-level gate drivers while maintaining <1.8W conduction loss at 2.5A.
Fast switching speed	t_D(ON) = 3.7ns, t_F = 8.4ns - Reduces transition losses in >500kHz SMPS designs; supports high-frequency operation without excessive gate drive power.
Low gate charge	Q_g = 1.0nC @ -4.5V - Minimizes required gate driver current (e.g., <10mA peak for 1MHz switching), easing driver IC selection.
Green RoHS compliance	Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); fully compliant with EU RoHS 2015/863/EU - Meets global environmental regulations for industrial and consumer end equipment.

Applications

Use Scenario: Controlled hot-swap enable/disable of downstream USB peripherals or accessories.

IC Role / Device Role: P-channel high-side load switch with integrated body diode for reverse-current blocking.

Use Value: -2.1V V_GS(TH) ensures full enhancement with 3.3V GPIO control; 134mΩ R_DS(ON) at -4.5V enables <100mV drop at 300mA, preserving bus voltage stability.

Power Management Unit (PMU)

LED Backlight Driver

IC Role / Device Role: Discrete power switch for auxiliary rails (e.g., VIO, VREF) within PMU subsystems.

Use Value: 159°C/W R_θJA allows operation up to +70°C ambient without heatsink; low leakage (<800nA IDSS) prevents standby current accumulation.

Use Scenario: PWM-controlled current sink for white LED strings in portable displays.

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) = 50mΩ @ -4.5V (lower), V_DSS = -20V (reduced), SOT23 package	Better suited for 5V-input systems; insufficient for 24V rail protection due to lower V_DSS	Select when V_IN ≤ 12V and lowest possible R_DS(ON) is critical; verify gate drive compatibility with -2.0V V_GS(TH).
SI2301DDS-T1-BE3	R_DS(ON) = 115mΩ @ -4.5V (higher), V_DSS = -20V, same SOT23 footprint	Limited to ≤12V applications; higher conduction loss increases thermal stress at >2A loads	Acceptable for cost-sensitive 3.3V/5V logic-driven switches where efficiency is secondary to BOM cost.

Compared with DMG3415L-7 and SI2301DDS-T1-BE3, DMP3165L-13 uniquely balances -30V rating, 134mΩ R_DS(ON) at -4.5V, and 6.5ns t_RR, making it optimal for 24V-input buck converters and industrial load-switching where voltage margin and switching fidelity are jointly critical.

FAQ

What is the maximum continuous drain current for DMP3165L-13 at +70°C ambient?

The maximum continuous drain current is -2.7A at T_A = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations on standard FR-4 PCBs with minimum recommended pad layout; actual current capability improves with enhanced copper area or forced airflow.

Does DMP3165L-13 have an integrated body diode, and what are its key parameters?

Yes, it includes a monolithic body diode with V_SD = -0.83V (typical) at I_S = -2.7A and reverse recovery time t_RR = 6.5ns at I_F = -1.0A, di/dt = 100A/μs. These values are measured with V_GS = 0V and support efficient freewheeling in synchronous rectifier configurations.

Can DMP3165L-13 be driven directly by a 3.3V microcontroller GPIO?

Yes - its gate threshold voltage range of -1.3V to -2.1V ensures full enhancement with 3.3V logic, as V_GS = -3.3V exceeds |V_GS(TH)|. However, gate resistor selection (e.g., 10–47Ω) is recommended to dampen ringing caused by 12.5Ω intrinsic gate resistance and PCB inductance.

What is the thermal resistance junction-to-ambient for DMP3165L-13 on a standard FR-4 board?

R_θJA is 159°C/W for steady-state operation on FR-4 with 2oz copper and minimum recommended pad layout (Note 5). With a 1-inch square copper plate, R_θJA improves to 98°C/W (Note 6), enabling higher power handling in thermally optimized layouts.
