Product details

Overview

DMP3045LFVW-7 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI®3333-8 package, featuring 42 mΩ R_DS(ON) at V_GS = −10 V, −19.9 A continuous drain current at T_C = +25°C, and thermally optimized 5°C/W R_θJC. It serves as a high-density load switch in power management rails and battery protection circuits.

For engineers reviewing the DMP3045LFVW-7 datasheet, DMP3045LFVW-7 pinout, DMP3045LFVW-7 application, or DMP3045LFVW-7 equivalent, this page delivers verified electrical parameters, validated thermal performance, confirmed PowerDI3333-8 terminal mapping, and real-world switching behavior for low-voltage DC-DC and USB-C power path design.

Technical Context

This MOSFET employs a trench-gate silicon process to achieve low on-resistance while maintaining fast switching (t_D(OFF) = 24.6 ns, Q_g = 13.6 nC at V_GS = −10 V) and robust avalanche capability (E_AS = 30.8 mJ). Its gate threshold voltage range of −1.0 V to −2.1 V enables reliable turn-on with standard logic-level drive.

The device integrates an ESD-protected gate (±20 V V_GSS) and uses a thermally efficient exposed-drain PowerDI3333-8 package with 0.072 g mass and UL 94V-0 molding compound. Junction-to-case thermal resistance is fixed at 5°C/W, enabling predictable thermal design when mounted to PCB copper planes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−30 V - Withstands up to 30 V reverse drain-source voltage before breakdown, suitable for 24 V system rails.
R_DS(ON)	42 mΩ @ V_GS = −10 V - Delivers <0.25 W conduction loss at 4.9 A, critical for efficiency in portable power switches.
I_D (T_C = +25°C)	−19.9 A - Supports high-current load switching when heatsinked to case, e.g., in hot-swap controllers.
Q_g	13.6 nC @ V_GS = −10 V - Enables fast turn-on with low gate driver current demand, reducing switching losses in PWM applications.
R_θJC	5°C/W - Allows direct thermal modeling from junction to PCB copper pad, simplifying thermal layout for compact designs.
V_GS(TH)	−1.0 to −2.1 V - Ensures full enhancement with 3.3 V or 5 V logic-level gate drive without level-shifting circuitry.
E_AS	30.8 mJ - Absorbs inductive energy during fault events (e.g., motor stall), improving system robustness without external snubbers.

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) = 45 mΩ @ −4.5 V; smaller PowerDI3333-8 footprint but lower I_D (−12 A at T_C = +25°C).	Suitable for lower-current 3.3 V–driven loads where gate drive voltage is limited.	Select when V_GS ≤ −4.5 V is guaranteed and peak current <12 A; avoid if 19.9 A capability is required.
SI2301DS-T1-BE3	R_DS(ON) = 115 mΩ @ −4.5 V; SOT-23 package, 3.2 A I_D rating, no exposed drain pad.	Fits ultra-compact layouts but lacks thermal headroom for sustained >2 A operation.	Choose only for space-limited prototypes or low-duty-cycle signals; not recommended for continuous power switching.

Compared with DMG3415L-7 and SI2301DS-T1-BE3, DMP3045LFVW-7 delivers superior current handling and thermal performance in the same footprint, making it optimal for production-grade 24 V industrial and automotive power switches requiring reliability under sustained load.

FAQ

What is the maximum safe operating temperature for DMP3045LFVW-7?

The junction temperature must not exceed +150°C under any condition. At T_A = +25°C with minimum FR-4 pad layout, power dissipation is limited to 0.9 W (R_θJA = 135°C/W); with 2 oz copper thermal bias, it rises to 2.1 W (R_θJA = 61°C/W). Derating curves in Figure 12 define safe operating area for pulsed conditions.

Can DMP3045LFVW-7 be used in synchronous rectification?

No - it is a single P-channel MOSFET without integrated driver or bootstrap circuitry. Its body diode forward voltage (V_SD = −0.7 to −1.2 V) and reverse recovery time (t_RR = 12.7 ns) are not optimized for high-frequency synchronous rectification; dedicated SR controllers or dual-N-channel configurations are preferred.

Is the exposed drain pad electrically isolated?

No - the exposed drain pad is electrically connected to pins 2, 3, 4, 5, 7, and 8 (all labeled "D" in the pinout). It must be soldered to a PCB copper pour designated as the drain net and thermally coupled to ground or power plane per recommended pad layout in the datasheet.

Does DMP3045LFVW-7 require external gate resistors in typical switching applications?

A gate resistor (e.g., 6 Ω as used in timing measurements) is recommended to damp ringing and control dV/dt during switching. The device's 10.4 Ω intrinsic gate resistance and 13.6 nC total gate charge make it compatible with standard microcontroller GPIO drivers, but external resistance improves EMI and reduces shoot-through risk in half-bridge configurations.
