Product details

Overview

IPI45N06S4L08AKSA2 from Infineon Technologies is a 60 V, 45 A N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, AEC-Q101 qualified for automotive power switching, with R_DS(on) = 7.9 mΩ at V_GS = 10 V and 100% single-pulse avalanche tested to 97 mJ. It operates up to 175 °C and supports high-current motor drive and DC-DC converter primary-side switching.

For engineers reviewing the IPI45N06S4L08AKSA2 datasheet, IPI45N06S4L08AKSA2 pinout, IPI45N06S4L08AKSA2 application, or IPI45N06S4L08AKSA2 equivalent, key selection criteria include its 7.9 mΩ R_DS(on), 180 A pulsed drain current, 2.1 K/W junction-to-case thermal resistance, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V–48 V automotive systems. Its gate threshold voltage (1.2–2.2 V) enables robust 3.3 V/5 V logic-level drive compatibility while maintaining low leakage (I_DSS ≤ 1 µA at 60 V).

The integrated body diode features 0.6–1.3 V forward voltage at 45 A and 33 ns reverse recovery time, supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal design is enabled by MSL1 rating (260 °C peak reflow) and validated 175 °C continuous operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage for 48 V nominal battery systems with 2× transient margin
R_DS(on) max	7.9 mΩ at V_GS = 10 V - Enables <1.8 W conduction loss at 45 A continuous current
I_D continuous	45 A at T_C = 25 °C - Limited by bondwire; supports high-current motor phase legs
E_AS	97 mJ - Confirmed single-pulse avalanche energy for inductive load turn-off protection
R_thJC	2.1 K/W - Enables direct heatsink mounting with predictable thermal path for thermal modeling
Q_g total	49–64 nC - Defines gate driver current requirement (~1.3 A avg for 50 ns switching)
V_GS(th)	1.2–2.2 V - Ensures reliable turn-on with 3.3 V microcontroller GPIO without level-shifting

Pinout & Package

PG-TO262-3-1 (3-pin straight-lead variant of TO-220 footprint), thermally enhanced with isolated drain tab. Pin 1: Gate; Pin 2: Drain (tab); Pin 3: Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives PWM signal; requires ≤64 nC charge for full enhancement; low input capacitance (C_iss = 3680–4780 pF) reduces driver loading
Pin 2 (Drain)	High-side power output	Connected to heatsink via isolated metal tab; carries full load current and withstands 60 V transients
Pin 3 (Source)	Power return reference	Serves as local ground reference for gate drive; must be low-inductance connection to minimize switching oscillation

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements
100% avalanche tested	Each unit verified for 97 mJ single-pulse ruggedness-no derating needed for inductive loads
MSL1 reflow rating	Withstands 260 °C peak solder profile without delamination or parameter shift
Green product (RoHS)	Lead-free, halogen-free construction compliant with EU Directive 2011/65/EU
175 °C operating limit	Enables placement near hot engine components without thermal throttling or lifetime degradation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP45N06S4L08AKSA2	Same die, PG-TO220-3-1 package; higher R_thJA (62 K/W vs 40 K/W on PCB)	Better suited for discrete heatsink mounting; less optimal for SMD-reflow assembly	Select when mechanical mounting constraints favor TO-220 over TO-262
IPB45N06S4L08AKSA2	Same die, PG-TO263-3-2 (D²PAK) package; identical R_DS(on) and thermal specs	Optimized for automated SMT assembly with exposed drain pad; requires larger PCB copper area	Select when board-level automation and thermal performance on FR4 dominate mechanical fit

Compared with IPP45N06S4L08AKSA2 and IPB45N06S4L08AKSA2, the IPI45N06S4L08AKSA2 offers identical electrical performance in a through-hole PG-TO262-3-1 package-ideal for mixed-technology boards where leaded components coexist with SMT, and where manual rework or field replacement is required.

FAQ

What is the maximum allowable gate-source voltage for IPI45N06S4L08AKSA2?

The absolute maximum V_GS is ±16 V. Operation beyond this risks permanent gate oxide damage. For reliable long-term use, gate drive should be clamped to ≤12 V with a Zener diode or active clamp circuit, especially in noisy automotive environments where transient coupling may occur.

Does IPI45N06S4L08AKSA2 require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. For 45 A switching at 20 kHz, a 3.5 Ω resistor is validated in the datasheet (t_d(on)/t_r/t_d(off)/t_f measured with R_G = 3.5 Ω). Lower values increase EMI risk; higher values slow switching and raise dynamic losses.

Can IPI45N06S4L08AKSA2 be used in parallel configurations?

Yes-its positive temperature coefficient for R_DS(on) (increases with T_j) enables inherent current sharing. Successful paralleling requires matched layout: identical gate trace lengths, Kelvin source connections, and symmetrical thermal paths to each device's heatsink interface.

Is the body diode suitable for continuous freewheeling in synchronous rectification?

The body diode is rated for 45 A continuous forward current and has a typical V_SD of 0.95 V at 45 A and 25 °C. While usable for freewheeling, its 33 ns t_rr and 32 nC Q_rr make it less efficient than external Schottky diodes in high-frequency (>100 kHz) synchronous rectifiers.
