Product details
Overview
STD95P3LLH6AG from STMicroelectronics is an AEC-Q101-qualified P-channel automotive Power MOSFET in DPAK (TO-252) package, featuring -30 V VDS, 5 mΩ typ. RDS(on) at VGS = -10 V, -80 A continuous drain current, and 104 W total power dissipation. It serves as a high-current, logic-level high-side switch in battery disconnect and load switching circuits.
For engineers reviewing the STD95P3LLH6AG datasheet, STD95P3LLH6AG pinout, STD95P3LLH6AG application, or STD95P3LLH6AG equivalent, key selection criteria include its low gate charge (113 nC), high avalanche energy (650 mJ), thermal resistance junction-to-case (1.2 °C/W), and robust source-drain diode recovery (27 ns trr).
Technical Context
This P-channel MOSFET uses STripFET™ H6 trench-gate technology to achieve ultra-low on-resistance and minimized gate drive losses. Its logic-level gate threshold (–1 to –2.5 V) enables direct interface with 3.3 V/5 V microcontrollers without level-shifting.
The device supports high-pulsed currents (–320 A IDM) and exhibits stable performance across –55 to 150 °C operating junction temperature. Its SOA curve is optimized for inductive load switching with controlled dv/dt and di/dt handling.

| Qg | 113 nC - Reduces gate driver power demand and switching transition time |
| EAS | 650 mJ - Withstands single-pulse inductive energy spikes without failure |
| trr | 27 ns - Minimizes body diode recovery loss during synchronous rectification or freewheeling |
| Rthj-case | 1.2 °C/W - Allows efficient heat transfer to heatsink or PCB copper area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF4905PbF | RDS(on) = 20 mΩ @ –10 V; non-AEC-Q101; TO-220 package | Lacks automotive qualification and thermal performance for underhood use | Select only for non-automotive, lower-current (<40 A), through-hole designs |
| STP95P3LLH6 | Same die, TO-220 package; no exposed drain tab; Rthj-case = 1.5 °C/W | Higher thermal resistance limits continuous current in compact layouts | Prefer for prototyping or legacy TO-220 footprints where DPAK rework is impractical |
Compared with IRF4905PbF and STP95P3LLH6, STD95P3LLH6AG delivers superior thermal efficiency (1.2 °C/W), AEC-Q101 compliance, and surface-mount scalability-making it the optimal choice for production automotive PCBs requiring high reliability and space-constrained layouts.

FAQ
Is STD95P3LLH6AG suitable for high-side switching in 12 V automotive systems?
Yes. As a P-channel MOSFET with –30 V VDS, logic-level gate threshold (–1 to –2.5 V), and –80 A continuous current rating, it is explicitly designed for high-side switching in 12 V battery architectures. Its low RDS(on) and high avalanche energy ensure robust operation during load dump and cranking events.
What is the maximum PCB copper area required for thermal performance at full rated current?
When mounted on a 1-inch² FR-4 board with 2 oz copper, Rthj-pcb is 50 °C/W. To maintain Tj ≤ 150 °C at –80 A (104 W), a minimum of 1-inch² thermal pad connected to the drain tab is required. For sustained full-load operation, a heatsink or multi-layer thermal plane is recommended.
Does STD95P3LLH6AG include an integrated body diode, and what are its recovery characteristics?
Yes. It features a monolithic source-drain body diode rated for –80 A continuous and –320 A pulsed current. Its reverse recovery time is 27 ns with 17 nC Qrr at ISD = –80 A and di/dt = 100 A/µs-enabling efficient freewheeling in inductive load applications without external diodes.
Can STD95P3LLH6AG be driven directly by a 3.3 V microcontroller GPIO?
No-direct 3.3 V drive is insufficient for full enhancement. At VGS = –3.3 V, RDS(on) rises significantly above specification. A dedicated gate driver or level shifter is required to deliver –4.5 V or –10 V to achieve specified 9.7 mΩ or 5 mΩ on-resistance respectively.
