Product details
Overview
IPD85P04P4L06ATMA1 from Infineon Technologies is a P-channel logic-level enhancement-mode MOSFET rated for -40 V VDS, 6.4 mΩ RDS(on) at VGS = -10 V and ID = -85 A, with AEC qualification and 175 °C maximum junction temperature. It serves as a high-current load switch in automotive power distribution modules, battery disconnect circuits, and reverse polarity protection.
For engineers reviewing the IPD85P04P4L06ATMA1 datasheet, IPD85P04P4L06ATMA1 pinout, IPD85P04P4L06ATMA1 application, or IPD85P04P4L06ATMA1 equivalent, key selection criteria include its -85 A continuous drain rating at TC = 25 °C, 1.7 K/W RthJC, 100% avalanche tested capability, and PG-TO252-3-313 surface-mount package with exposed drain tab.
Technical Context
This OptiMOS®-P2 device uses trench-based silicon technology optimized for low RDS(on) and fast switching in DC-DC converters and motor control H-bridge high-side configurations. Its gate threshold voltage range (-1.2 to -2.2 V) ensures reliable turn-on with standard 3.3 V or 5 V logic drivers.
Dynamic parameters include Ciss = 6580 pF (max), Qg = 104 nC (max), and tr/tf of 10 ns/39 ns respectively - enabling efficient operation up to 100 kHz in synchronous rectification and PWM-controlled power stages.

FAQ
What is the maximum allowable gate-source voltage for IPD85P04P4L06ATMA1?
The absolute maximum VGS is ±16 V, with recommended operating range limited to -10 V for full RDS(on) specification and long-term reliability. Exceeding -16 V risks permanent gate oxide damage, while operation below -4.5 V increases RDS(on) to 10.3 mΩ, raising conduction losses significantly.
Is IPD85P04P4L06ATMA1 suitable for high-frequency switching above 500 kHz?
No - its 104 nC total gate charge and 6580 pF input capacitance result in practical switching limits near 100–200 kHz. At 500 kHz, gate drive losses would dominate efficiency, and thermal management becomes impractical without aggressive heatsinking beyond the 1.7 K/W RthJC limit.
Does this MOSFET include an integrated body diode, and what are its characteristics?
Yes - it features a monolithic parasitic body diode with VSD = -1.3 V (max) at IF = -85 A and Tj = 25 °C, trr = 56 ns (typ), and Qrr = 64 nC (typ). These values support moderate-speed freewheeling but are not optimized for synchronous rectification in high-frequency SMPS.
How does the PG-TO252-3-313 package differ from standard TO-252 variants?
The PG-TO252-3-313 designation indicates Infineon's proprietary variant with enhanced thermal pad geometry and tighter dimensional tolerances for automated optical inspection. It maintains mechanical compatibility with standard TO-252 footprints but delivers improved thermal resistance (1.7 K/W vs typical 2.0–2.5 K/W) due to optimized copper slug thickness and solder mask opening.
