Product details

Overview

DMP3165L-7 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 serves as a high-efficiency synchronous rectifier or load switch in compact DC-DC converters.

For engineers reviewing the DMP3165L-7 datasheet, DMP3165L-7 pinout, DMP3165L-7 application, or DMP3165L-7 equivalent, key selection criteria include gate threshold voltage (-1.3 to -2.1V), low input capacitance (300pF C_iss), fast switching (3.7ns t_D(ON)), thermal resistance (98°C/W with copper pad), and RoHS-compliant green packaging.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while preserving fast turn-on/turn-off dynamics. Its -2.1V maximum V_GS(TH) enables direct logic-level drive from 3.3V microcontrollers without level-shifting.

The device integrates an intrinsic body diode with V_SD = -0.83V @ I_S = -2.7A and exhibits low Q_gd/Q_g ratio (0.5nC / 2.0nC), supporting high-frequency PWM operation up to 1MHz in buck converter topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - supports 24V rail derating and transient clamping in industrial power supplies
R_DS(ON)	90mΩ @ V_GS = -10V - limits conduction loss to ≤0.8W at 3A, enabling thermally constrained layouts
I_D (continuous)	-3.3A @ T_A = +25°C - sufficient for 5–10W point-of-load converters with minimal heatsinking
C_iss	300pF - reduces gate drive power requirement and EMI generation in high-speed switching
t_D(ON)	3.7ns - enables clean edge control in 500kHz–1MHz synchronous rectification
V_GS(TH)	-1.3 to -2.1V - ensures reliable turn-on with standard 3.3V GPIOs, eliminating external bias networks
P_D (with pad)	1.3W - achievable on FR-4 with 1-inch² copper pour, supporting unregulated thermal design

Pinout & Package

Package: SOT23 - surface-mount plastic case, 0.008g weight, UL 94V-0 rated, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for P-channel channel	Connected to higher potential rail; referenced for gate drive and body diode cathode
2 (Gate)	Control electrode for channel inversion	Low-input-capacitance node requiring <2nC total charge for full enhancement
3 (Drain)	Main current output terminal	Connected to load or switching node; carries reverse recovery current during freewheeling

Key Features

Feature	Design Value
Low R_DS(ON) at -4.5V	134mΩ - enables 3.3V logic-driven operation in battery-powered systems without gate boosters
Fast switching speed	t_F = 8.4ns - minimizes overlap loss in synchronous buck converters operating >300kHz
Low gate leakage	±80nA @ V_GS = ±12V - prevents unintended turn-on in high-impedance gate drive circuits
Green packaging	Halogen- and antimony-free, <900ppm Br/Cl - meets IPC-1752A Class 3 material declarations for automotive Tier 1

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3165L-7	N-channel counterpart with identical R_DS(ON) and package; requires high-side gate driver	Used in high-side switch configurations where bootstrap or charge-pump drive is available	Select when topology permits N-channel use for lower gate charge and better R_DS(ON) scalability
AO3401	Higher R_DS(ON) (85mΩ @ -4.5V vs. 134mΩ); larger C_iss (490pF); same SOT23 footprint	Preferred in cost-sensitive consumer power banks where 5% efficiency loss is acceptable	Choose only if BOM cost reduction outweighs thermal derating and EMI impact in high-frequency designs

Compared with DMN3165L-7 and AO3401, DMP3165L-7 uniquely balances logic-level drivability, low dynamic losses, and thermal performance in space-constrained P-channel roles-making it optimal for 3.3V-controlled buck stages and USB PD protection where gate simplicity and efficiency are co-prioritized.

FAQ

What is the maximum safe operating junction temperature for DMP3165L-7?

The absolute maximum junction temperature is +150°C per the datasheet. Operation above +125°C requires derating of continuous current to maintain reliability; at +150°C ambient, the device supports only ~1.1A continuous due to R_DS(ON) increase and thermal resistance limitations.

Can DMP3165L-7 be used in linear regulator pass transistor applications?

No-it is not characterized or qualified for linear mode operation. The Safe Operating Area (SOA) curve shows pulse-limited capability only; sustained linear operation risks thermal runaway due to positive temperature coefficient of R_DS(ON) and lack of SOA-rated DC dissipation.

Does DMP3165L-7 require a gate resistor for stability in switching applications?

A gate resistor (typically 10–47Ω) is recommended to dampen ringing caused by gate-drain capacitance and PCB trace inductance. Without it, measured V_GS overshoot exceeds ±20V rating under fast-edge drive, risking long-term gate oxide degradation.

Is the body diode of DMP3165L-7 suitable for reverse-current blocking in bidirectional power paths?

Yes-the body diode has V_SD = -0.83V typical at -2.7A and t_RR = 6.5ns, making it suitable for reverse-blocking in USB Type-C DRP applications when paired with appropriate gate control logic to prevent shoot-through.
