Product details

Overview

DMP3025LK3-13-01 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in TO252-3L (DPAK) package, featuring 25 mΩ R_DS(on) at V_GS = −10 V and −16.1 A continuous drain current at T_A = 25°C. It delivers low conduction loss and fast switching for high-efficiency power management in DC-DC converters and LED backlighting circuits.

For engineers reviewing the DMP3025LK3-13-01 datasheet, DMP3025LK3-13-01 pinout, DMP3025LK3-13-01 application, or DMP3025LK3-13-01 equivalent, key selection criteria include verified R_DS(on) at −4.5 V (41 mΩ), body diode forward voltage (−0.80 to −1.2 V), safe operating area limits, thermal resistance (R_θJA = 29.0 °C/W on 50 mm × 50 mm 2 oz FR4), and gate charge (Q_g = 31.6 nC at V_GS = −10 V).

Technical Context

This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters, leveraging its negative threshold voltage (V_GS(th) = −1.0 to −3.0 V) and low gate-to-drain capacitance (C_rss = 178 pF) to minimize Miller-induced turn-off delay. Its integrated body diode supports freewheeling with t_rr = 16.2 ns and Q_rr = 10 nC.

The device uses a planar trench-gate structure optimized for R_DS(on)–Q_g trade-off, with specified linear derating (34.5 mW/°C) and junction-to-lead thermal resistance (R_θJL = 1.02 °C/W), enabling reliable operation up to T_J = 150°C in surface-mount power stages.

Key Specifications

Parameter	Value and Actual Design Meaning

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) = 28 mΩ @ −4.5 V; Q_g = 22 nC; TO252 package	Lower gate charge improves switching efficiency but higher R_DS(on) increases conduction loss above 5 A	Select when gate drive strength is limited and average load current stays below 6 A
SI2301DS-T1-BE3	R_DS(on) = 115 mΩ @ −4.5 V; SOT-23 package; I_D = −2.7 A	Smaller footprint and lower cost, but unsuitable for >3 A continuous loads due to thermal limits	Select only for space-constrained, low-power bias rails where peak current ≤2 A

Compared with DMG3415L-7 and SI2301DS-T1-BE3, DMP3025LK3-13-01 offers superior R_DS(on)–Q_g balance for medium-power (>6 A) applications, with validated thermal performance on standard DPAK footprints and proven reliability in industrial DC-DC modules.

FAQ

What is the maximum continuous drain current for DMP3025LK3-13-01 at 70°C ambient?

The maximum continuous drain current is −12.9 A at T_A = 70°C when mounted on a 50 mm × 50 mm × 1.6 mm FR4 PCB with 2 oz copper, per the linear derating curve (34.5 mW/°C). This reflects thermal limitation-not silicon current capability-and assumes still-air conditions.

Does DMP3025LK3-13-01 have a built-in body diode, and what are its key parameters?

Yes, it integrates a source-drain body diode with forward voltage V_SD = −0.80 to −1.2 V at I_S = −1.7 A and reverse recovery time t_rr = 16.2 ns at dI/dt = 100 A/µs. These values are measured with V_GS = 0 V and define freewheeling behavior in synchronous rectifier applications.

Can DMP3025LK3-13-01 be driven directly by a 3.3 V microcontroller GPIO?

No-its gate threshold voltage range is −1.0 to −3.0 V, requiring a negative gate-source bias for full enhancement. A 3.3 V GPIO cannot produce the required −4.5 V or −10 V drive; a dedicated gate driver or level-shifting circuit is mandatory for reliable switching.

What is the moisture sensitivity level (MSL) and reflow profile compliance for this part?

DMP3025LK3-13-01 has MSL Level 1 per J-STD-020D, meaning it is not moisture-sensitive and may be stored indefinitely at ≤30°C/60% RH without dry-pack requirements. Reflow must follow Diodes' recommended profile: peak temperature ≤260°C, time above 217°C ≤60 seconds, and ramp rate ≤3°C/s.
