Product details

Overview

IPI45N06S4L08AKSA3 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, rated for 60 V V_DS, 7.9 mΩ R_DS(on) (max at V_GS=10 V, I_D=45 A), and 175 °C operation. It delivers 45 A continuous drain current at T_C=100 °C and supports automotive body control modules requiring robust 12 V load switching with integrated avalanche ruggedness.

For engineers reviewing the IPI45N06S4L08AKSA3 datasheet, IPI45N06S4L08AKSA3 pinout, IPI45N06S4L08AKSA3 application, or IPI45N06S4L08AKSA3 equivalent, key selection criteria include its 2.1 K/W junction-to-case thermal resistance, 100% single-pulse avalanche tested performance (E_AS=97 mJ), gate plateau voltage of 3.6 V, and SMD-compatible thermal footprint on FR4 PCBs.

Technical Context

This OptiMOS®-T2 power transistor uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its gate threshold voltage (1.2–2.2 V) enables direct drive from standard microcontroller GPIOs, while the 3.6 V gate plateau ensures stable Miller region control during hard-switching transitions.

The device integrates a fast-recovery body diode with t_rr = 33 ns and Q_rr = 32 nC at 30 V reverse bias, supporting synchronous rectification and freewheeling in high-frequency DC-DC converters. Thermal design leverages its 2.1 K/W R_thJC and MSL1 reflow compatibility up to 260 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Supports full 12 V automotive battery transient (load dump up to 40 V) with margin
R_DS(on) max	7.9 mΩ at V_GS=10 V, I_D=45 A - Enables <1.8 W conduction loss at 45 A
I_D continuous	45 A at T_C=100 °C - Rated for sustained high-current loads without derating below 100 °C case temp
E_AS	97 mJ - Confirmed single-pulse avalanche energy withstand capability for inductive load switching
t_r/t_f	2 ns / 8 ns - Fast switching enables >200 kHz PWM operation with minimal turn-on/turn-off losses
Q_g	49–64 nC - Gate charge optimized for low-driver-power 12 V gate drive with 3.6 V plateau
V_GS(th)	1.2–2.2 V - Ensures reliable turn-on with 3.3 V or 5 V logic-level controllers

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 60 V automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP45N06S4L-08	Same die, PG-TO220-3-1 package - higher R_thJA (62 K/W vs 40 K/W on PCB)	Limited to lower-power applications due to reduced thermal dissipation capability	Select when cost-sensitive through-hole assembly is required and power dissipation remains ≤35 W
IPB45N06S4L-08	Same die, PG-TO263-3-2 package - identical R_thJC but different mounting geometry and creepage	Better suited for automated SMT lines with large copper pour; requires different stencil design	Select for fully automated surface-mount production where board space allows D²PAK footprint

Compared with IPP45N06S4L-08 and IPB45N06S4L-08, the IPI45N06S4L08AKSA3 offers optimal balance of thermal performance (2.1 K/W R_thJC), manufacturability (straight-lead TO262), and automotive qualification - making it preferred for mid-power body electronics where both reliability and assembly flexibility matter.

FAQ

What is the maximum allowable gate-source voltage for IPI45N06S4L08AKSA3?

The absolute maximum V_GS is ±16 V per datasheet specifications. Operation beyond this risks permanent gate oxide damage. Recommended gate drive is 10 V for full R_DS(on) optimization, with 4.5 V sufficient for logic-level control in low-power modes.

Does IPI45N06S4L08AKSA3 require a gate resistor for automotive applications?

Yes - a gate resistor (typically 5–22 Ω) is required to dampen ringing, control dI/dt, and prevent shoot-through in half-bridge configurations. The 49–64 nC total gate charge and 3.6 V plateau voltage make resistor selection critical for balancing switching speed and EMI.

Can IPI45N06S4L08AKSA3 replace older OptiMOS®-T1 devices in existing designs?

Yes - it is a direct drop-in replacement for IPB45N06S3-07 and IPP45N06S3-07 in most cases, offering improved R_DS(on) (7.9 mΩ vs 8.7 mΩ), lower Q_g, and enhanced avalanche ruggedness without layout changes.

Is the drain tab electrically isolated in the PG-TO262-3-1 package?

No - the drain is internally connected to the metal tab and must be electrically isolated from the heatsink using insulating thermal pads or mica washers unless the heatsink is referenced to drain potential in the circuit topology.
