Product details

Overview

IPI80P03P4L04AKSA1 from Infineon Technologies is a P-channel logic-level enhancement-mode MOSFET in PG-TO262-3-1 package, rated for -30 V V_DS, 4.1 mΩ R_DS(on) at V_GS = -10 V and I_D = -80 A, with 175 °C maximum junction temperature and AEC qualification for automotive reverse battery protection circuits.

For engineers reviewing the IPI80P03P4L04AKSA1 datasheet, IPI80P03P4L04AKSA1 pinout, IPI80P03P4L04AKSA1 application, or IPI80P03P4L04AKSA1 equivalent, key selection criteria include R_DS(on) at 4.5 V gate drive, avalanche energy (410 mJ), thermal resistance (R_thJC = 1.1 K/W), and AEC-Q101 compliance for harsh-environment automotive power path control.

Technical Context

This device operates as a high-current, low-side P-channel switch in reverse polarity protection circuits, where gate drive is referenced to system ground and source connects to battery positive. Its logic-level threshold (V_GS(th) = -1.0 to -2.0 V) enables direct interface with 3.3 V/5 V microcontrollers without level-shifting.

Designed for continuous conduction up to -80 A at T_C = 100 °C, it features 100% unclamped inductive switching (UIS) tested, integrated body diode with t_rr = 100 ns and Q_rr = 80 nC, and optimized capacitance profile (C_iss = 8670–11300 pF, C_rss = 65–130 pF) for fast, low-loss switching in DC-fed protection stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-30 V - Maximum drain-source blocking voltage for 12 V automotive systems with load dump margin
R_DS(on) @ V_GS = -10 V	3.4–4.1 mΩ - Enables <1 W conduction loss at 80 A, critical for thermally constrained engine bay layouts
I_D (continuous)	-80 A @ T_C = 100 °C - Sustained current capability matching alternator output and starter motor surge demands
E_AS	410 mJ - Confirmed single-pulse avalanche energy supporting robustness against inductive kickback in solenoid/relay drivers
R_thJC	1.1 K/W - Junction-to-case thermal resistance enabling direct heatsink mounting for passive thermal management
Q_g	125–160 nC - Total gate charge determining drive strength requirement for <150 ns turn-off delay in fast-protection applications
t_r/t_f	11 ns / 40 ns - Rise/fall times enabling sub-µs response to reverse polarity events without excessive EMI

Pinout & Package

PG-TO262-3-1 package: isolated tab (drain), 3-pin through-hole variant with standard TO-220 footprint compatibility; drain-connected metal tab enables direct thermal coupling to heatsink.

Pin 1 (Source)	Source terminal	Connects to system ground; carries full load current and defines reference for gate drive
Pin 2 (Gate)	Control input	Logic-level compatible; requires <2.0 V negative threshold to fully enhance; minimal drive current needed
Pin 3 (Drain)	High-side connection point	Connected to battery positive; tab is electrically tied to drain for low-inductance thermal path

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per JESD47
100% UIS tested	Each unit screened for 410 mJ single-pulse avalanche energy-no derating required in inductive load protection
Logic-level gate	V_GS(th) max -2.0 V ensures reliable turn-on with 3.3 V MCU GPIO, eliminating external level shifters

FAQ

What is the maximum gate-source voltage rating for IPI80P03P4L04AKSA1?

The absolute maximum gate-source voltage is -16 V, with recommended operating range between 0 V and -10 V. Exceeding -16 V risks permanent gate oxide damage. The device is designed for logic-level drive, so -4.5 V provides full enhancement with R_DS(on) ≤ 7 mΩ, making it compatible with standard 3.3 V and 5 V microcontroller outputs without external level shifting.

Does IPI80P03P4L04AKSA1 require a gate resistor for automotive applications?

A gate resistor (typically 10–47 Ω) is recommended to dampen ringing and limit peak gate current during fast switching, especially in noisy automotive environments. While not strictly required for basic on/off operation, it improves EMI performance and prevents spurious turn-on due to dv/dt coupling. The device's Q_g of 125–160 nC means a 22 Ω resistor yields ~3.5 ns RC time constant-well within safe drive timing margins.

How does the body diode performance impact its use in reverse battery protection?

The integrated body diode has V_SD = -1.3 V at -80 A and t_rr = 100 ns, enabling fast recovery during polarity reversal transients. In normal forward operation, it remains reverse-biased and inactive. During reverse connection, the diode conducts briefly before the MOSFET turns off, limiting fault current rise time and reducing stress on upstream fuses-critical for meeting ISO 7637-2 pulse 4 immunity requirements.

Is IPI80P03P4L04AKSA1 suitable for hot-swap applications in 12 V systems?

Yes-it supports controlled hot-swap insertion due to its 175 °C junction rating, 100% UIS testing, and low R_DS(on). When paired with appropriate gate slew-rate control (e.g., RC network), it limits inrush current during plug-in events. Its -80 A continuous rating and -320 A pulsed capability handle typical hot-swap surge profiles defined in IEEE 1626 and MIL-STD-1399, provided PCB layout maintains <1.1 K/W thermal path to heatsink.
