Product details

Overview

IPP45N06S4L08AKSA1 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 R_DS(on) = 7.9 mΩ (max) 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 IPP45N06S4L08AKSA1 datasheet, IPP45N06S4L08AKSA1 pinout, IPP45N06S4L08AKSA1 application, or IPP45N06S4L08AKSA1 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 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 low forward voltage (V_SD = 0.6–1.3 V at 45 A) and fast recovery (t_rr = 33 ns, Q_rr = 32 nC), supporting synchronous rectification and hard-switched flyback topologies without external diode supplementation.

FAQ

Is IPP45N06S4L08AKSA1 suitable for 48 V battery system switching?

Yes. With 60 V V_DS, 45 A continuous current rating, and 175 °C maximum junction temperature, it supports 48 V nominal battery systems including transient overvoltage conditions up to 60 V. Its 7.9 mΩ R_DS(on) limits conduction loss to <1.8 W at full load, making it appropriate for high-duty-cycle applications like traction inverters and onboard chargers.

What is the gate drive voltage range for reliable operation?

The device specifies V_GS(th) between 1.2 V and 2.2 V and is fully enhanced at V_GS ≥ 10 V. It supports logic-level drive down to 4.5 V (R_DS(on) = 9.7–14 mΩ), but for minimal conduction loss and thermal margin, 10 V gate drive is recommended. Absolute maximum V_GS is ±16 V.

Does IPP45N06S4L08AKSA1 include an integrated body diode?

Yes. It features a monolithically integrated fast-recovery body diode with V_SD = 0.6–1.3 V at 45 A and t_rr = 33 ns. This diode is rated for 45 A continuous forward current and 180 A pulsed current, enabling use in synchronous rectification and freewheeling applications without external diodes.

How does the AEC-Q101 qualification impact design validation?

AEC-Q101 qualification confirms the device has passed stress tests including HTGB, HTRB, UHAST, and temperature cycling, specifically for discrete semiconductors in automotive applications. This eliminates need for duplicate qualification testing by Tier 1 suppliers and provides assurance of long-term reliability in under-hood environments with thermal cycling and vibration exposure.
