Product details
Overview
PMG85XPH from Nexperia is a P-channel enhancement-mode Trench MOSFET in SOT363 (SC-88) package, rated for −20 V drain-source voltage, −2 A continuous drain current at VGS = −4.5 V, and 90–115 mΩ RDS(on) at 25 °C. It serves as a high-side load switch or high-speed line driver in compact power management circuits.
For engineers reviewing the PMG85XPH datasheet, PMG85XPH pinout, PMG85XPH application, or PMG85XPH equivalent, this device is selected for low-threshold switching in space-constrained DC-DC bias rails, relay drivers, and fast-switching logic-level control where gate drive compatibility with 3.3 V/5 V microcontrollers is required.
Technical Context
This MOSFET uses Trench MOSFET technology to achieve low gate charge (QG(tot) = 4.8–7.2 nC) and fast switching (td(on) = 13 ns, tf = 25 ns), enabling efficient operation in PWM-controlled loads. Its −0.65 to −1.15 V gate threshold ensures reliable turn-on with standard logic-level gate drives.
The device integrates a built-in source-drain diode (VSD = −0.7 to −1.2 V at IS = −0.7 A), supports peak drain current up to −8 A (10 µs pulse), and maintains RDS(on) stability across junction temperatures from −55 °C to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum blocking voltage for high-side switching in 12 V systems |
| ID (continuous) | −2 A at VGS = −4.5 V, Tj = 25 °C - Supports moderate-load switching without heatsinking |
| RDS(on) | 90–115 mΩ at VGS = −4.5 V, ID = −2 A - Low conduction loss for <100 mW dissipation at full load |
| VGS(th) | −0.65 to −1.15 V - Enables direct drive from 3.3 V GPIO without level-shifting |
| QG(tot) | 4.8–7.2 nC - Minimizes gate drive power and enables >1 MHz switching in optimized layouts |
| tf/tr | 25 ns / 35 ns - Supports clean edge transitions in digital load control and relay driving |
| Ptot | 375 mW (FR4, standard footprint) - Defines thermal derating envelope for PCB layout planning |

Applications
| Relay Driver | High-Speed Line Driver |
|---|---|
Use Scenario: Driving electromagnetic relays in industrial PLC I/O modules with 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: High-side switch controlling relay coil current; operates in on/off mode with <100 µs response. Use Value: Low VGS(th) eliminates need for discrete level shifters; four drain pins reduce contact resistance and improve reliability under surge conditions. |

IC Role / Device Role / Timing Role: Controlled high-side pass element with integrated overtemperature protection via RDS(on) monitoring. Use Value: 90 mΩ RDS(on) limits dropout to <200 mV at 2 A; SOT363 footprint saves board area versus SO-8 alternatives. |
Use Scenario: Providing regulated bias voltage to gate drivers or op-amps in isolated DC-DC converters. IC Role / Device Role / Timing Role: Synchronous rectifier or auxiliary supply switch operating at 100–500 kHz PWM frequency. Use Value: Low QG(tot) (4.8–7.2 nC) reduces gate drive losses; stable RDS(on) up to 150 °C ensures consistent efficiency across temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2053LKQ-7 | −20 V, −2.8 A, RDS(on) = 70 mΩ @ −4.5 V; WDFN-6 package (1.6 × 1.6 mm) | Lower RDS(on) but larger footprint and higher gate charge (9.5 nC); requires tighter layout control | Preferred when lower conduction loss justifies larger board area and higher gate drive capability |
| SI2305DS-T1-GE3 | −20 V, −2.6 A, RDS(on) = 65 mΩ @ −4.5 V; SOT-23 package (single drain) | Higher RDS(on) temperature coefficient and no multi-drain thermal path; limited to ≤1.5 A continuous | Acceptable for lower-current (<1.2 A), cost-sensitive designs where SOT-23 placement is preferred |
Compared with DMN2053LKQ-7 and SI2305DS-T1-GE3, PMG85XPH offers balanced trade-offs: lowest package height and smallest footprint among the three, unique quad-drain thermal design for improved reliability in pulsed loads, and optimal gate charge for 3.3 V MCU drive-making it ideal for space- and drive-limited high-side switches.

FAQ
Is PMG85XPH suitable for 3.3 V microcontroller gate drive?
Yes. With a gate threshold voltage of −0.65 to −1.15 V and guaranteed turn-on at VGS = −3.3 V, PMG85XPH fully enhances using standard 3.3 V GPIO outputs. Its low gate charge (4.8–7.2 nC) further ensures minimal drive current demand and fast switching without external buffers.
What is the maximum continuous drain current at 100 °C junction temperature?
At Tj = 100 °C and VGS = −4.5 V, the maximum continuous drain current is −1.3 A per the Absolute Maximum Ratings table. This reflects thermal derating due to reduced channel mobility and increased RDS(on), requiring appropriate PCB copper area for heat dissipation.
Does PMG85XPH have an integrated ESD protection diode?
No. The datasheet does not specify on-chip ESD protection structures. External TVS or RC filtering is recommended for gate protection in environments with electrostatic discharge risk, especially given its low VGS(th) and sensitive gate oxide.
Can PMG85XPH be used in parallel configurations?
Yes-its four parallel drain terminals and matched die characteristics support current sharing in parallel arrangements. However, individual gate resistors (≤10 Ω) and symmetrical PCB routing are required to ensure simultaneous switching and prevent current imbalance during transients.
