Product details
Overview
DMP4026LSS from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SO-8 package, designed for high-efficiency power management with 25 mΩ RDS(ON) at VGS = −10 V, −7.2 A continuous drain current, and fast switching (tF = 24 ns). It serves as a synchronous rectifier or load switch in DC-DC converters and motor control circuits.
For engineers reviewing the DMP4026LSS datasheet, DMP4026LSS pinout, DMP4026LSS application, or DMP4026LSS equivalent, key selection criteria include its low RDS(ON) at −4.5 V (45 mΩ), 100% production-tested UIS capability, SO-8 thermal performance (RθJA = 60.3 °C/W with copper pad), and −55 °C to +150 °C operating range.
Technical Context
This MOSFET uses planar trench-gate technology optimized for low conduction loss while maintaining controlled gate charge (QG = 45 nC at −10 V) and low output capacitance (COSS = 221 pF). Its body diode exhibits tRR = 17.3 ns and QRR = 8.7 nC under 100 A/μs di/dt, supporting efficient synchronous rectification.
The device features a robust 62 mJ avalanche energy rating (EAS) and operates reliably across industrial temperature extremes. Its gate threshold voltage (VGS(TH) = −0.8 to −1.8 V) ensures stable turn-on behavior with standard logic-level drive in high-side configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −40 V - Supports 36 V nominal bus systems with 10% margin for transients |
| RDS(ON) | 25 mΩ @ VGS = −10 V - Enables ≤0.54 W conduction loss at 4.7 A load current |
| ID (max) | −7.2 A @ TA = +25°C - Sustains full-rated current on FR-4 with 1-inch² copper pad |
| QG | 45 nC @ VGS = −10 V - Determines gate driver power requirement and switching speed trade-off |
| tF | 24 ns - Limits switching transition time to reduce overlap losses in half-bridge topologies |
| EAS | 62 mJ - Withstands single-pulse inductive energy without failure in motor drive flyback paths |
| TJ range | −55 °C to +150 °C - Qualified for extended industrial and under-hood automotive ambient conditions |

| 5 | Gate (G) | High-impedance control input requiring <2.5 Ω gate resistance to damp ringing during fast transitions |
| 6, 7, 8 | Drain (D) | Power output node connected to internal die backside; requires thermal pad connection to heatsink copper area |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG4407LSS-13 | RDS(ON) = 22 mΩ @ −10 V, but higher QG = 52 nC and no production UIS test | Suitable for lower-frequency switching where gate drive loss is less critical | Prefer DMP4026LSS when avalanche ruggedness or sub-20 ns fall time is required |
| SI4435DY-T1-GE3 | RDS(ON) = 20 mΩ @ −10 V, but rated only to −30 V VDSS and lacks JEDEC high-reliability qualification | Limited to ≤24 V systems; not recommended for 36 V industrial bus applications | Choose DMP4026LSS for 40 V systems needing guaranteed avalanche performance and extended temperature operation |
Compared with DMG4407LSS-13 and SI4435DY-T1-GE3, DMP4026LSS delivers superior avalanche energy handling (62 mJ vs. untested or unspecified), tighter VGS(TH) distribution (−0.8 to −1.8 V), and validated SO-8 thermal performance under industrial ambient conditions - making it optimal for mission-critical 36–40 V power switches.

FAQ
What is the maximum continuous drain current for DMP4026LSS at 70°C ambient?
The DMP4026LSS supports −5.7 A continuous drain current at TA = +70°C when mounted on an FR-4 board with 1-inch² copper pad (PD = 2.0 W, RθJA = 60.3 °C/W). Derating follows linear junction-to-ambient thermal model up to TJ = 150°C.
Does DMP4026LSS require a gate resistor for stability?
Yes - a series gate resistor of 2–10 Ω is recommended to damp high-frequency oscillation caused by gate-drain capacitance (CRSS = 191 pF) and PCB trace inductance. The datasheet specifies RG = 6 Ω for timing measurements, confirming this value suppresses ringing without compromising tF = 24 ns.
Can DMP4026LSS be used in automotive applications?
The standard DMP4026LSS is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., DMP4026LSSQ-13) with PPAP documentation, IATF 16949 manufacturing, and AEC-Q101 stress testing. For non-automotive industrial use, its −55 °C to +150 °C rating and JEDEC high-reliability qualification apply.
How does the body diode forward voltage affect synchronous rectification?
VSD = −0.7 to −1.0 V at −1 A ensures low forward conduction loss during dead-time, while tRR = 17.3 ns and QRR = 8.7 nC minimize reverse-recovery current spikes that cause shoot-through or EMI in buck converters operating above 100 kHz.
