Product details
Overview
DMP4050SSD-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -40V VBRDSS, 50 mΩ RDS(on) at VGS = -10 V, and -5.2 A continuous drain current at TA = +25°C; it delivers low conduction loss and fast switching for synchronous buck converters and motor drive half-bridges.
For engineers reviewing the DMP4050SSD-13 datasheet, DMP4050SSD-13 pinout, DMP4050SSD-13 application, or DMP4050SSD-13 equivalent, key selection criteria include dual P-channel topology, SO-8 thermal performance (RθJA = 100 °C/W), body diode forward voltage (-0.86 V at -6 A), gate charge (6.9 nC at VGS = -4.5 V), and AEC-Q101 qualification status.
Technical Context
This dual P-channel MOSFET integrates two identical enhancement-mode silicon die in a single SO-8 package with shared drain terminals (D1/D2) and independent source/gate pairs (S1/G1, S2/G2). Its symmetric layout enables complementary high-side switching without external level-shifting circuitry.
The device features a low-threshold VGS(th) range of -1.0 to -3.0 V, enabling robust turn-on with standard logic-level gate drivers, and exhibits tightly controlled dynamic parameters: Ciss = 674 pF, Qgd = 3.4 nC, and tf = 12.6 ns - all critical for minimizing switching losses in DC-DC applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBRDSS | -40 V - Maximum blocking voltage before avalanche conduction; defines safe operating range in 36 V automotive or 24 V industrial bus systems. |
| RDS(on) | 50 mΩ @ VGS = -10 V - Conduction loss of 260 mW at -5.2 A; enables >95% efficiency in 12 V input/5 V output synchronous buck stages. |
| ID (continuous) | -5.2 A @ TA = +25°C - Sustained load current capability under natural convection on 25 mm × 25 mm PCB; derates to -4.0 A at +70°C ambient. |
| Qg | 6.9 nC @ VGS = -4.5 V - Gate drive energy required per switching cycle; determines minimum gate driver peak current (e.g., 1.4 A for 5 ns rise time). |
| VSD | -0.86 V @ IS = -6 A - Forward voltage of integrated body diode; sets reverse recovery loss and dead-time sensitivity in synchronous rectification. |
| tr/tf | 3.1 ns / 12.6 ns - Fast edge rates reduce overlap conduction loss; supports >1 MHz switching in compact power supplies. |
Pinout & Package
Package: SO-8 surface-mount plastic package (JEDEC MS-012AC), 4.9 mm × 6.0 mm footprint, 1.75 mm height, matte tin-plated copper lead frame, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain 1 | Common high-side switch node for Channel 1; electrically tied to D2 internally in dual-die configuration. |
| S1 | Source 1 | Return path for Channel 1 load current; referenced to gate drive ground for high-side operation. |
| G1 | Gate 1 | Control terminal for Channel 1; requires negative bias relative to S1 to enhance conduction. |
| S2 | Source 2 | Return path for Channel 2 load current; isolated from S1 to support independent load control. |
| G2 | Gate 2 | Control terminal for Channel 2; decoupled from G1 to enable asynchronous or phase-shifted switching. |
| D2 | Drain 2 | Common high-side switch node for Channel 2; bonded to same internal drain metallization as D1. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at logic-level drive | 50 mΩ @ VGS = -10 V enables efficient high-side switching using standard 3.3 V or 5 V microcontroller GPIOs with external level shifters. |
| Fully AEC-Q101 qualified | Validated for automotive temperature range (-55°C to +150°C) and mechanical stress; suitable for under-hood motor control modules. |
| Green, halogen-free construction | Meets <900 ppm Br/Cl and <1000 ppm Sb limits; complies with EU RoHS 2011/65/EU and JESD204B environmental requirements. |
| Optimized dynamic capacitance ratio | Ciss/Coss = 5.9 supports stable gate drive with minimal Miller-induced shoot-through risk in hard-switched topologies. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVT-7 | Lower RDS(on) (32 mΩ @ -10 V) but higher Qg (12.5 nC); SO-8 package with exposed pad for improved thermal performance. | Better suited for thermally constrained 12 V/8 A DC-DC where junction temperature must stay below 110°C. | Select when thermal resistance RθJA < 70 °C/W is mandatory and board space allows thermal pad layout. |
| SI7850DP-T1-GE3 | Higher VBRDSS (-60 V), higher RDS(on) (65 mΩ @ -10 V); same SO-8 footprint but non-AEC-Q101 rated. | Preferred for industrial 48 V battery-powered tools requiring wider voltage margin but no automotive qualification. | Choose when system input can reach -55 V transiently and AEC-Q101 compliance is not required. |
Compared with DMP4050SSD-13, DMC2038LVT-7 offers superior thermal handling at the cost of higher gate drive demand, while SI7850DP-T1-GE3 trades off automotive reliability for extended voltage headroom - making DMP4050SSD-13 optimal for cost-sensitive, AEC-Q101–mandated 24–36 V applications.

FAQ
What is the maximum allowable gate-source voltage for DMP4050SSD-13?
The absolute maximum VGS is ±20 V per the datasheet, but AEC-Q101 qualification restricts continuous operation to ±16 V. Exceeding ±16 V risks long-term gate oxide degradation in automotive environments, even if short-term survival is observed. Designers should use gate clamp circuits or driver ICs with programmable VGS limits to ensure compliance.
Can DMP4050SSD-13 be used in a synchronous buck converter without external level shifting?
Yes - its P-channel architecture allows direct connection of gate drivers referenced to the source terminals (S1/S2), eliminating bootstrap capacitors or high-side level shifters. However, gate drive must swing negative relative to source (e.g., 0 V to -10 V), requiring a dual-rail or inverting driver stage rather than standard N-channel gate drivers.
How does the dual-die thermal coupling affect SOA in simultaneous conduction mode?
When both channels operate at equal power, thermal resistance drops to RθJA = 58 °C/W (vs. 100 °C/W for one active die), increasing safe operating area by 72%. This enables combined continuous current up to -6.8 A (derated) before exceeding TJ = 150°C on a standard 25 mm × 25 mm PCB - verified in Diodes' AP02002 thermal simulation model.
Is the body diode optimized for reverse recovery in synchronous rectification?
Yes - the specified trr = 18 ns and Qrr = 12.7 nC reflect fast, soft recovery characteristics validated under 100 A/µs di/dt conditions. This minimizes voltage spikes and EMI during freewheeling transitions, supporting reliable operation in 500 kHz–1 MHz synchronous buck converters without snubbers.
