Product details

Overview

DMP3056L-13 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in SOT23 package, featuring 50 mΩ R_DS(ON) at V_GS = −10 V, −4.3 A continuous drain current at 25°C, and low gate threshold voltage (−1 to −2.1 V). It serves as a high-efficiency load switch or power rail controller in compact DC-DC converter output stages.

For engineers reviewing the DMP3056L-13 datasheet, DMP3056L-13 pinout, DMP3056L-13 application, or DMP3056L-13 equivalent, key selection criteria include verified R_DS(ON) at −4.5 V, thermal resistance (91 °C/W), fast switching (t_R = 4.7 ns), and RoHS-compliant SOT23 footprint compatibility with space-constrained PCB layouts.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low on-resistance while maintaining controlled gate charge (Q_G = 5.8 nC at V_GS = −4.5 V) and low input capacitance (C_iss = 642 pF). Its negative V_GS(TH) enables direct logic-level drive from 3.3 V or 5 V microcontrollers without level-shifting.

The device integrates an intrinsic body diode with V_SD = −1.2 V at −1.7 A and exhibits stable R_DS(ON) over temperature (1.0× at 150°C vs. 25°C under V_GS = −4.5 V), supporting reliable operation in ambient temperatures up to +125°C in thermally constrained enclosures.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V - Withstands reverse-biased drain-source voltage up to 30 V in high-side switch or reverse-polarity protection configurations.
R_DS(ON)	50 mΩ @ V_GS = −10 V - Enables ≤215 mW conduction loss at −4.3 A, critical for thermally limited SOT23 applications.
I_D (continuous)	−4.3 A @ T_A = 25°C - Supports sustained load currents in USB-powered peripherals and battery management circuits.
Q_G	5.8 nC @ V_GS = −4.5 V - Allows efficient gate drive with low-current GPIOs and minimizes switching energy loss in PWM control.
R_θJA	91 °C/W - Defines junction-to-ambient thermal rise per watt; requires minimal copper area for ≤1.38 W dissipation in standard FR-4 layout.
V_GS(TH)	−1 to −2.1 V - Ensures full enhancement with 3.3 V logic outputs, eliminating need for external gate pull-up resistors in low-voltage systems.

Pinout & Package

Package: SOT23 (Standard), surface-mount plastic case with matte tin–annealed copper leadframe; UL 94V-0 rated; moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Main current path output terminal	Connected to high-side power rail or load return; carries full switched current and must be routed with adequate copper width.
2 (Gate)	Control input for channel conduction	Accepts negative V_GS to turn on; requires low-impedance drive due to 15 Ω gate resistance and 642 pF input capacitance.
3 (Source)	Reference node for gate control and current return	Biased at system V_CC or ground depending on high/low-side configuration; forms cathode of integrated body diode.

Key Features

Feature	Design Value
Low R_DS(ON) at logic-level drive	70 mΩ @ V_GS = −4.5 V - Enables use with 3.3 V MCU I/O without gate driver, reducing BOM count in portable electronics.
Fast switching speed	t_R = 4.7 ns, t_F = 18.2 ns - Supports >1 MHz PWM frequencies in synchronous buck converters with minimal dead-time loss.
Low gate leakage	I_GSS ≤ ±100 nA @ V_GS = ±20 V - Prevents unintended turn-on during long standby periods in always-on IoT sensor nodes.
Halogen- and antimony-free "Green" construction	<900 ppm Br, <900 ppm Cl, <1000 ppm Sb - Meets IPC-1752A material declaration requirements for automotive and medical OEMs.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG3415L-7	R_DS(ON) = 42 mΩ @ −4.5 V; higher Q_G = 10.5 nC; same SOT23 package	Better conduction loss but slower switching; less suitable for >500 kHz PWM	Select when lowest static loss dominates over switching frequency constraints.
SI2301DS-T1-BE3	R_DS(ON) = 115 mΩ @ −4.5 V; lower V_GS(TH) = −0.45 V; same SOT23 footprint	Higher on-resistance but enhanced gate sensitivity; prone to partial turn-on near logic thresholds	Prefer only in ultra-low-voltage (1.8–2.5 V) gate drive scenarios where margin is critical.

Compared with DMG3415L-7 and SI2301DS-T1-BE3, DMP3056L-13 delivers optimal balance of R_DS(ON), Q_G, and V_GS(TH) for 3.3 V–5 V logic-driven load switching-enabling faster transitions than SI2301DS and lower dynamic loss than DMG3415L in mid-frequency DC-DC applications.

FAQ

What is the maximum safe operating junction temperature for DMP3056L-13?

The absolute maximum junction temperature is +150°C, validated per JEDEC JESD22-A104. Operation above +125°C requires derating of I_D and P_D based on Figure 5 and Figure 7 in DS37386 Rev. 6–2; thermal vias and ≥1 in² 2 oz copper are recommended for sustained 1.38 W dissipation.

Can DMP3056L-13 be used in high-side switch configurations with 3.3 V microcontroller GPIOs?

Yes-its V_GS(TH) range (−1 to −2.1 V) ensures full enhancement with 3.3 V logic outputs driving the gate negative relative to source. A 10 kΩ pull-down resistor on gate is recommended to prevent floating during reset, and gate drive impedance must remain ≤100 Ω for t_R/t_F compliance.

Does DMP3056L-13 include built-in ESD protection?

No-this MOSFET lacks on-chip ESD protection structures. Per DS37386 Section 1, handling requires ANSI/ESDA/JEDEC JS-001 Class 1B compliance; board-level TVS diodes or series resistors are mandatory for I/O pins exposed to user-accessible connectors or cables.

Is the SOT23 package of DMP3056L-13 compatible with reflow profiles for lead-free assembly?

Yes-the device is fully RoHS 3 compliant (≤1000 ppm antimony, ≤900 ppm bromine/chlorine) and qualified for Pb-free reflow per J-STD-020, Level 1 moisture sensitivity. Peak temperature must not exceed 260°C for ≤30 seconds, with ramp rates ≤3°C/s before and after reflow.
