Product details

Overview

IPP45N06S4L08AKSA2 from Infineon Technologies is a 60 V, 45 A N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, AEC-Q101 qualified for automotive applications, with 7.9 mΩ max R_DS(on) at V_GS = 10 V and 100% single-pulse avalanche tested to 97 mJ. It serves as a high-current main switch in 12 V/24 V DC-DC converters and motor control stages.

For engineers reviewing the IPP45N06S4L08AKSA2 datasheet, IPP45N06S4L08AKSA2 pinout, IPP45N06S4L08AKSA2 application, or IPP45N06S4L08AKSA2 equivalent, key selection criteria include R_DS(on) at 4.5 V and 10 V, thermal resistance (R_thJC = 2.1 K/W), avalanche energy rating, and AEC-Q101 qualification status for under-hood use.

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in hard-switched 60 V automotive power stages. Its gate threshold voltage (1.2–2.2 V) enables robust 3.3 V/5 V logic-level drive compatibility while maintaining noise immunity.

The integrated body diode exhibits low forward voltage (0.6–1.3 V at 45 A) and fast reverse recovery (t_rr = 33 ns, Q_rr = 32 nC), supporting synchronous rectification and freewheeling in high-frequency buck converters and H-bridge motor drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-source blocking voltage for 12 V/24 V automotive systems with load dump margin.
R_DS(on) max @ V_GS=10 V	7.9 mΩ - Enables ≤1.6 W conduction loss at 45 A, reducing heatsink requirements in space-constrained modules.
I_D continuous @ T_C=100°C	45 A - Sustains full rated current at elevated case temperatures common in engine bay environments.
E_AS	97 mJ - Confirmed single-pulse avalanche capability supports inductive load switching without external snubbers.
R_thJC	2.1 K/W - Direct junction-to-case thermal path enables efficient heat transfer to heatsink via TO-220 mounting tab.
Q_g total	49–64 nC - Defines gate drive power requirement; compatible with standard 1 A peak gate drivers at ≤100 kHz switching.
t_r/t_f	2 ns / 8 ns - Fast switching transitions minimize overlap loss in hard-switched topologies.

FAQ

What is the maximum gate-source voltage rating for IPP45N06S4L08AKSA2?

The absolute maximum gate-source voltage is ±16 V. Operation beyond this range risks permanent gate oxide damage. Recommended drive is 10 V for full R_DS(on) specification, with 4.5 V sufficient for logic-level control in low-power gate driver circuits.

Does IPP45N06S4L08AKSA2 require a gate resistor for safe operation?

Yes - a series gate resistor (typically 5–22 Ω) is required to dampen ringing, limit peak gate current, and control dV/dt during switching. Without it, parasitic oscillation can cause shoot-through in bridge configurations and increase EMI emissions.

Is the drain tab of IPP45N06S4L08AKSA2 electrically isolated from the package mounting surface?

No - the metal tab is internally connected to the drain terminal. Electrical isolation must be achieved using insulating shoulder washers or thermal interface pads when mounting to a grounded heatsink, especially in high-side configurations.

Can IPP45N06S4L08AKSA2 replace older OptiMOS®-T1 devices in existing designs?

Yes - it is a direct drop-in replacement for IPP45N06S3L-09 and similar predecessors, offering lower R_DS(on) (7.9 mΩ vs. 9.5 mΩ), improved avalanche energy (97 mJ vs. 75 mJ), and tighter V_GS(th) distribution, with identical pinout and footprint.
