Product details
Overview
DMP3025LK3-13 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in TO252-3L package, featuring 25 mΩ RDS(on) at VGS = −10 V, −16.1 A continuous drain current at TA = 25°C, and fast switching with 3.5 ns turn-on delay. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and backlighting circuits.
For engineers reviewing the DMP3025LK3-13 datasheet, DMP3025LK3-13 pinout, DMP3025LK3-13 application, or DMP3025LK3-13 equivalent, key selection criteria include verified RDS(on) at −4.5 V (41 mΩ), body diode forward voltage (−0.80 to −1.2 V), SOA limits under pulsed conditions, and thermal resistance (RθJA = 29.0 °C/W on 50 mm × 50 mm 2 oz FR4).
Technical Context
This P-channel MOSFET operates with gate threshold voltage (VGS(th)) between −1.0 V and −3.0 V, enabling robust turn-on control in low-voltage logic-driven power stages. Its 1678 pF input capacitance (Ciss) and 178 pF reverse transfer capacitance (Crss) support stable high-frequency switching up to several hundred kHz in buck and boost topologies.
The device integrates a monolithic body diode with 16.2 ns reverse recovery time and 10 nC Qrr, allowing efficient synchronous rectification without external Schottky diodes. Thermal design is enabled by RθJL = 1.02 °C/W and validated derating curves for both 25 mm × 25 mm (1 oz) and 50 mm × 50 mm (2 oz) PCB layouts.
Key Specifications

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 | RDS(on) = 32 mΩ @ −4.5 V; lower ID (−7.5 A); smaller SOT-23 package | Not suitable for >5 A continuous loads; limited thermal mass for power dissipation | Select when board space is constrained and current demand is ≤5 A with forced air cooling. |
| SI2305DS-T1-GE3 | RDS(on) = 50 mΩ @ −4.5 V; higher VGS(th) (−1.5 to −2.5 V); SOT-23 package | Higher conduction loss at same current; less gate drive margin in noisy environments | Choose only if cost sensitivity outweighs efficiency requirements and thermal budget permits ≥2× RDS(on) loss. |
Compared with DMG3415L-7 and SI2305DS-T1-GE3, DMP3025LK3-13 delivers superior thermal performance via TO252-3L package and lowest RDS(on) at −4.5 V, making it optimal for high-current, high-reliability industrial power switches where PCB area allows.

FAQ
Is DMP3025LK3-13 still in active production?
No - Diodes Incorporated has officially discontinued DMP3025LK3-13, as confirmed in the May 2013 datasheet revision. However, Aetrix Electronics maintains legacy inventory with full traceability and supports last-time buy programs for industrial customers requiring extended supply continuity.
What is the maximum safe operating temperature for DMP3025LK3-13?
The absolute maximum junction temperature is 150°C, and the storage temperature range is −55°C to +150°C. For reliable long-term operation, junction temperature should be kept below 125°C using the provided RθJA = 29.0 °C/W (50 mm × 50 mm 2 oz FR4) derating curve and thermal pad layout guidelines.
Can DMP3025LK3-13 be used in linear regulation mode?
Yes - its SOA curve (page 3 of datasheet) validates safe linear operation up to −10 V VDS and −10 A ID at TA = 25°C with appropriate heatsinking. However, power dissipation must remain within PD = 4.3 W (steady-state) or follow the linear derating factor of 34.5 mW/°C above 25°C ambient.
Does DMP3025LK3-13 require a gate resistor for stability?
Yes - the datasheet recommends RG ≅ 6.0 Ω for switching characterization. A 4.7–10 Ω gate resistor suppresses ringing caused by Lg–Ciss resonance, ensures controlled dV/dt, and prevents false triggering due to Miller effect in high-di/dt applications like motor drives or hot-swap circuits.
