Product details
Overview
DMP3045LVT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSOT26 package, rated for -30V VDSS, 42 mΩ RDS(ON) @ VGS = -10V, and -5.4A continuous drain current at +25°C. It serves as a high-efficiency synchronous rectifier or load switch in low-voltage DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMP3045LVT-7 datasheet, DMP3045LVT-7 pinout, DMP3045LVT-7 application, or DMP3045LVT-7 equivalent, key selection criteria include gate threshold voltage (-1 to -2.1 V), low input capacitance (749 pF Ciss), fast switching times (tD(ON) = 4.4 ns), ESD-protected gate, and thermal resistance (RθJA = 104 °C/W on FR-4).
Technical Context
This MOSFET employs a trench-gate process optimized for low RDS(ON) while maintaining controlled gate charge (Qg = 14.3 nC @ VGS = -10V) and fast turn-on/turn-off dynamics (tR = 19.7 ns, tF = 26 ns). Its body diode exhibits VSD = -0.7 to -1.2 V at -1 A, supporting bidirectional conduction in buck converter freewheeling paths.
The device operates across -55°C to +150°C junction temperature range with specified avalanche energy (EAS = 30 mJ) and current (IAS = -7.8 A), enabling robust operation under transient overloads in power management systems without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage before avalanche onset; defines safe operating range in 24 V rail applications. |
| RDS(ON) | 42 mΩ @ VGS = -10V - Conduction loss of ~0.22 W at -4.9 A; enables >95% efficiency in compact 5 V–12 V point-of-load converters. |
| Qg | 14.3 nC @ VGS = -10V - Gate drive energy requirement; determines minimum driver capability for <20 ns switching transitions. |
| Ciss | 749 pF - Input capacitance defining Miller effect and gate drive impedance matching for stable PWM control. |
| RθJA | 104 °C/W - Thermal resistance on standard FR-4 PCB; limits max continuous power dissipation to 1.2 W at ambient +25°C. |
| VGS(TH) | -1 to -2.1 V - Threshold voltage range ensuring reliable turn-on with logic-level gate drivers (e.g., 3.3 V or 5 V microcontroller outputs). |
Pinout & Package
Package: TSOT26 - 6-pin ultra-thin surface-mount package (2.9 × 1.6 × 0.6 mm), lead-free, halogen-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (P-channel) | Reference node for gate drive; connects to higher potential rail in high-side switch configurations. |
| 2 (Gate) | Control input | Accepts negative VGS to enhance channel; requires ESD-safe handling due to integrated protection. |
| 3 (Drain) | Power output / load connection | Carries full load current; thermally coupled to exposed pad (Pin 6) for enhanced heat dissipation. |
| 4 (Source) | Source terminal (redundant bond) | Parallel source path reducing package inductance and improving current sharing in high-frequency switching. |
| 5 (Source) | Source terminal (redundant bond) | Additional low-inductance source connection supporting <10 MHz switching in synchronous buck topologies. |
| 6 (Exposed Pad) | Thermal & electrical ground | Must be soldered to PCB copper pour for thermal relief; electrically connected to Source (Pins 1, 4, 5). |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3045LVT-7 | N-channel counterpart with identical RDS(ON) (42 mΩ @ VGS = +10V) but requires high-side gate driver or bootstrap circuitry. | Suitable only in low-side switching configurations; incompatible with high-side load switch layouts without level shift. | Select when topology permits N-channel placement and gate drive complexity is acceptable for marginal RDS(ON) improvement at VGS = +4.5V. |
| SI2305DS-T1-GE3 | Higher RDS(ON) (60 mΩ @ VGS = -4.5V), lower Qg (7.5 nC), same TSOT26 package and pinout. | Better suited for low-power, low-frequency (<100 kHz) applications where gate drive strength is constrained. | Prefer when minimizing gate drive power dominates over conduction loss, e.g., battery-powered IoT sensors with intermittent duty cycle. |
Compared with DMN3045LVT-7 and SI2305DS-T1-GE3, DMP3045LVT-7 delivers optimal balance of low conduction loss at logic-level drive and robust switching performance-making it preferred for high-efficiency, medium-frequency DC-DC converters where gate drive simplicity and thermal margin are critical.

FAQ
What is the maximum continuous drain current at +70°C ambient?
The DMP3045LVT-7 supports -4.3 A continuous drain current at TA = +70°C when VGS = -10V, based on thermal derating from its 1.2 W power dissipation limit on FR-4 PCB with standard pad layout. This value assumes no forced airflow and accounts for RθJA = 104 °C/W and TJ(max) = +150°C.
Is the TSOT26 package pinout compatible with other Diodes P-channel MOSFETs?
Yes-the TSOT26 pinout (Source-Gate-Drain–Source–Source–Exposed Pad) is standardized across Diodes' DMP-series P-channel MOSFETs including DMP2035U, DMP3010L, and DMP3025L. Pin 1 is Source, Pin 2 is Gate, Pin 3 is Drain, Pins 4–5 are additional Source connections, and Pin 6 is the exposed thermal pad tied to Source internally.
Does this MOSFET require external gate resistors for stability?
No external gate resistor is required for basic stability, as the device's Crss = 79 pF and Qgd = 3 nC ensure minimal Miller-induced oscillation risk. However, a 5–10 Ω series gate resistor is recommended to dampen ringing during hard-switching above 1 MHz and reduce EMI in noise-sensitive applications like audio power stages.
Can DMP3045LVT-7 be used in automotive infotainment power supplies?
Yes-the DMP3045LVT-7 is manufactured in IATF 16949-certified facilities and has an AEC-Q101-qualified variant (DMP3045LVTQ-7). For automotive use, specify the Q-suffix part and confirm PPAP documentation; the base part meets temperature and reliability specs but lacks formal automotive qualification documentation.
