Product details
Overview
DMP3048LSD-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SO-8 package, rated for -30V VDSS, 48 mΩ RDS(ON) @ VGS = -10V, and -4.8A continuous drain current at +25°C. It serves as a high-efficiency synchronous rectifier or load switch in low-voltage DC-DC converters and power management circuits.
For engineers reviewing the DMP3048LSD-13 datasheet, DMP3048LSD-13 pinout, DMP3048LSD-13 application, or DMP3048LSD-13 equivalent, key selection criteria include its low RDS(ON) at -4.5V gate drive, AEC-Q101 qualification, SO-8 dual-drain layout, and fast switching performance with 29.6 nC total gate charge.
Technical Context
This MOSFET employs trench-gate silicon process technology to achieve low on-resistance while maintaining controlled gate charge (Qg = 29.6 nC @ VGS = -10V) and low output capacitance (Coss = 92 pF). Its dual-source/dual-drain SO-8 configuration supports paralleling or half-bridge topologies without external interconnects.
The device features a robust body diode with VSD = -0.7 V @ IS = -1 A and tRR = 10 ns, enabling efficient reverse recovery in synchronous buck stages. Thermal resistance RθJA is 75 °C/W with 1-inch² copper pad, supporting 1.7 W power dissipation under optimized PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage in off-state; suitable for 24V rail and automotive 12V systems with margin. |
| RDS(ON) | 48 mΩ @ VGS = -10V - Enables <150 mW conduction loss at 5A; critical for thermal budget in compact converters. |
| ID (continuous) | -4.8 A @ TA = +25°C - Sustains full-load current in space-constrained power stages with standard FR-4 layout. |
| Qg | 29.6 nC @ VGS = -10V - Determines gate driver strength requirement; enables <100 ns turn-off delay with 6Ω series resistor. |
| Ciss/Coss | 1438 pF / 92 pF @ VDS = -15V - Low Coss reduces switching loss during hard commutation; supports >1 MHz operation. |
| tRR | 10 ns - Fast body diode recovery minimizes shoot-through risk and ringing in synchronous rectification. |
| TJ range | -55°C to +150°C - Qualified per AEC-Q101; supports under-hood automotive and industrial ambient conditions. |

| G1, G2 | Gate terminals (internally connected) | Dual gate inputs reduce gate loop inductance and improve EMI behavior in high-dI/dt applications. |
| Pin 1–8 | Standard SO-8 footprint (see Diodes DS37455 Fig. 1) | Compatible with JEDEC MS-012AC; requires 1.27 mm pitch and 3.85 mm × 6.00 mm pad layout per manufacturer recommendation. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at -4.5V | 57 mΩ - Enables efficient operation from 5V logic-level gate drivers without level-shifting circuitry. |
| Fast switching speed | tF = 34 ns, tD(OFF) = 108 ns - Reduces transition losses in high-frequency (>500 kHz) DC-DC topologies. |
| AEC-Q101 qualified | Stress-tested for automotive reliability - Validated for temperature cycling, HTRB, and UHAST per AEC standard. |
| Green compound & RoHS | Halogen-free, antimony-free, lead-free - Meets IPC-1752 and EU RoHS 2 (2011/65/EU) compliance requirements. |
| Low input leakage | IGSS ≤ ±100 nA @ ±12V - Minimizes standby power loss in always-on power management functions. |

IC Role / Device Role / Timing Role: Low-noise, low-RDS(ON) pass element for precision current regulation in analog dimming path. Use Value: 0.074 g mass and SO-8 thermal profile enable tight thermal coupling to aluminum-backed PCBs, stabilizing LED forward voltage drift. |
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) = 42 mΩ @ -4.5V (lower), but VDSS = -20V only; SO-8 single-drain layout. | Not suitable for 24V systems requiring -30V rating; better for 5V/3.3V logic-driven loads. | Select when gate drive is limited to -4.5V and bus voltage ≤20V; avoid where 30V blocking margin is required. |
| SI3457DV-T1-GE3 | RDS(ON) = 55 mΩ @ -4.5V; higher Ciss (1700 pF); same SO-8 dual-drain package. | Higher switching loss due to larger input capacitance; less optimal for >1 MHz operation. | Prefer when cost sensitivity outweighs efficiency targets; verify gate driver capability for 1700 pF load. |
Compared with DMG3415L-7 and SI3457DV-T1-GE3, DMP3048LSD-13 uniquely balances -30V rating, dual-drain SO-8 layout, and 48 mΩ RDS(ON) at -10V-making it optimal for automotive 12V/24V power switches where both voltage margin and thermal performance are critical.

FAQ
What is the maximum safe operating junction temperature for DMP3048LSD-13?
The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C. Derating begins at +70°C ambient for continuous operation; thermal design must ensure RθJA ≤ 75°C/W with 1-inch² copper to sustain 1.7 W power dissipation.
Can DMP3048LSD-13 be used in a synchronous buck converter's high-side position?
No-it is a P-channel MOSFET intended for low-side or high-side switch configurations where gate drive is referenced to the source. In synchronous buck topologies, it is used exclusively on the low-side (source grounded) or as a high-side switch with gate drive ≥|VIN| above source potential.
Does DMP3048LSD-13 have an integrated ESD protection diode on the gate?
Yes-the device includes gate oxide protection per AEC-Q101 HBM testing (≥2 kV), verified by Diodes Incorporated's qualification report DS37455 Rev. 2. No external gate Zener is required for standard PCB handling, though layout best practices (short traces, ground guard ring) are recommended.
Is the SO-8 package of DMP3048LSD-13 compatible with standard reflow profiles?
Yes-its moisture sensitivity level is 1 (J-STD-020), meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard Pb-free reflow profiles (peak 260°C, 60 sec max above 217°C) without baking.
