Product details
Overview
DMP10H4D2SQ-7 from Diodes Incorporated is a 100V P-channel enhancement-mode MOSFET in SOT23 package, qualified to AEC-Q101 for automotive use. It delivers RDS(ON) = 4.2 Ω @ VGS = −10 V, ID = −0.27 A at TA = +25°C, and features integrated gate protection diode and ESD protection. It serves as a low-power load switch in DC-DC converters and solid-state relays.
For engineers reviewing the DMP10H4D2SQ-7 datasheet, DMP10H4D2SQ-7 pinout, DMP10H4D2SQ-7 application, or DMP10H4D2SQ-7 equivalent, key selection criteria include its −100 V VDSS, low gate threshold (−1.0 to −3.0 V), 87 pF Ciss, AEC-Q101 qualification, and SOT23 thermal resistance of 333 °C/W on FR-4.
Technical Context
This P-channel MOSFET operates with negative gate drive relative to source, enabling high-side switching without level-shifting circuitry in low-current power management rails. Its low VGS(TH) allows reliable turn-on from standard 3.3 V or 5 V logic in battery-operated systems.
The device integrates an ESD-protected gate structure and exhibits fast switching (tD(ON) = 3.3 ns, tF = 4.9 ns) with low total gate charge (Qg = 1.8 nC), supporting efficient operation in pulse-width modulated loads such as solenoid drivers and LED lamp controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −100 V: Maximum drain-source blocking voltage for high-voltage automotive rail isolation |
| RDS(ON) | 4.2 Ω @ VGS = −10 V: On-resistance determines conduction loss in 270 mA continuous load paths |
| ID | −0.27 A @ TA = +25°C: Continuous drain current rating for ambient-limited thermal design |
| Ciss | 87 pF: Input capacitance impacts gate drive strength requirement and switching speed |
| Qg | 1.8 nC: Total gate charge defines minimum driver energy needed per switching cycle |
| RθJA | 333 °C/W: Junction-to-ambient thermal resistance on standard FR-4 board dictates max power dissipation |
| VGS(TH) | −1.0 to −3.0 V: Gate threshold enables direct interface with 3.3 V microcontroller GPIOs |
Pinout & Package
Package: SOT23 - surface-mount plastic package with 3 terminals, 0.008 g mass, UL 94V-0 rated molding compound, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel device | Connected to higher potential rail; defines reference for gate drive and body diode cathode |
| 2 (Gate) | Control terminal for channel inversion | ESD-protected input requiring < ±20 V drive; low Ciss eases driving from low-power logic |
| 3 (Drain) | Current output terminal | Connects to load; body diode anode enables reverse-current freewheeling in inductive applications |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to −1.0 V enables robust turn-on from 3.3 V logic without external level shifters |
| Integrated gate protection diode | On-die clamping diode prevents gate oxide damage during transient overvoltage events |
| ESD protection | HBM-rated per JESD22-A114; eliminates need for external TVS on gate line in most automotive sub-systems |
| Small SOT23 footprint | 2.9 mm × 1.3 mm outline supports high-density PCB layouts in space-constrained modules like body control units |
Applications
| DC-DC Converter Load Switch | Battery Management System Enable |
|---|---|
Use Scenario: Enables/disables 12 V auxiliary rail in automotive buck converter during sleep mode to reduce quiescent current. IC Role / Device Role / Timing Role: High-side P-channel switch controlled by MCU GPIO; operates in static on/off state with infrequent transitions. Use Value: Low RDS(ON) minimizes voltage drop and power loss (< 30 mW at 270 mA), extending battery life in always-on modules. | Use Scenario: Controls power to fuel pump controller or HVAC fan driver in battery-operated subsystems. IC Role / Device Role / Timing Role: Load switch isolating downstream circuitry; activated only during vehicle runtime to prevent parasitic drain. Use Value: AEC-Q101 qualification ensures reliability across −40°C to +125°C ambient, meeting ISO 16750-4 cold-cranking requirements. |
| Solid-State Relay Replacement | LED Lamp Driver |
Use Scenario: Replaces electromechanical relay in door lock actuator or mirror heater control. IC Role / Device Role / Timing Role: Low-duty-cycle switching element handling pulsed 100–500 mA loads with fast turn-off to suppress inductive kickback. Use Value: Fast tF = 4.9 ns and integrated body diode provide clean current commutation without external flyback diode. | Use Scenario: Drives 12 V LED arrays in interior lighting or dashboard backlighting. IC Role / Device Role / Timing Role: Constant-current sink switch modulated via PWM from microcontroller; operates at ≤1 kHz. Use Value: Low Qg = 1.8 nC reduces gate driver power consumption and enables use of low-cost discrete transistor drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET load switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN10H4D2S-7 | N-channel counterpart with same RDS(ON) and VDSS, but requires high-side gate driver or bootstrap circuitry | Suitable only where layout permits low-side switching or driver IC integration | Select when system already uses N-channel drivers and board space allows repositioning load to ground side |
| AO3401 | Higher RDS(ON) (5.5 Ω @ −10 V), lower VDSS (−30 V), non-AEC-Q101 qualified | Limited to non-automotive industrial or consumer applications with <30 V rails | Choose for cost-sensitive non-automotive designs where −30 V rating suffices and AEC compliance is not required |
Compared with DMN10H4D2S-7 and AO3401, DMP10H4D2SQ-7 uniquely combines AEC-Q101 qualification, −100 V rating, and SOT23 form factor-making it the only option for space-constrained, high-voltage automotive load switching without external level-shifting support.

FAQ
What is the maximum junction temperature for DMP10H4D2SQ-7?
The absolute maximum junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. Operation above this limit risks permanent device failure. Derating curves in Figure 6 show RDS(ON) increases by ~2× from −55°C to +150°C, requiring thermal design margin for sustained 270 mA loads.
Does DMP10H4D2SQ-7 require an external gate resistor?
No external gate resistor is mandatory due to its low Qg (1.8 nC) and RG (15.3 Ω), but a 10 Ω series resistor is recommended to damp ringing and limit peak gate current during fast edge transitions in noisy automotive environments.
Can DMP10H4D2SQ-7 be used in linear (analog) regulation mode?
It is not designed for linear regulation. Its Safe Operating Area (Figure 12) shows DC operation is limited to ≤0.27 A at VDS < 10 V; higher VDS × ID products cause rapid thermal runaway due to low power dissipation (0.38 W) and high RθJA.
Is the body diode suitable for continuous freewheeling current?
Yes-the body diode supports up to −0.42 A continuous source current (IS) and has VSD = −0.82 V typical at −0.2 A, making it suitable for inductive load recovery in solenoid and relay drivers without adding external diodes.
