Product details

Overview

IPI45N06S4L08AKSA1 from Infineon Technologies is a 60 V, 45 A N-channel enhancement-mode OptiMOS™-T2 power MOSFET in PG-TO262-3-1 package, AEC-Q101 qualified for automotive applications, 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 control and DC-DC conversion.

For engineers reviewing the IPI45N06S4L08AKSA1 datasheet, IPI45N06S4L08AKSA1 pinout, IPI45N06S4L08AKSA1 application, or IPI45N06S4L08AKSA1 equivalent, key selection criteria include its 7.9 mΩ R_DS(on), 175 °C junction rating, AEC-Q101 qualification, TO-262 thermal performance (R_thJC = 2.1 K/W), and integrated body diode with t_rr = 33 ns.

Technical Context

This device implements an optimized trench-gate process for low conduction and switching losses, targeting high-efficiency 12 V/24 V automotive power stages. Its gate threshold voltage (1.2–2.2 V) enables robust 3.3 V and 5 V logic-level drive compatibility while maintaining low leakage (I_DSS ≤ 1 µA at 60 V).

The MOSFET features fully characterized dynamic parameters: C_iss = 4780 pF, C_oss = 1090 pF, Crss = 80 pF, Q_g = 64 nC, and fast switching (t_d(on) = 9 ns, t_f = 8 ns) under standard 3.5 Ω gate resistance conditions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB45N06S4L08AKSA1	PG-TO263-3-2 package; identical die, lower R_thJA on PCB due to surface-mount thermal pad	Better suited for space-constrained SMD layouts with forced-air cooling	Select when board area is limited and thermal interface to copper pour is controllable
IPP45N06S4L08AKSA1	PG-TO220-3-1 package; same die, higher R_thJC (2.3 K/W), requires mechanical heatsink mounting	Preferred for through-hole prototyping and legacy industrial designs with bolted heatsinks	Select when manual assembly, serviceability, or mechanical robustness outweighs thermal optimization

Compared with IPB45N06S4L08AKSA1 and IPP45N06S4L08AKSA1, the IPI45N06S4L08AKSA1 offers identical electrical performance in a mid-profile through-hole package with superior thermal resistance (R_thJC = 2.1 K/W) and simplified heatsink integration versus TO-220, while avoiding SMD reflow constraints of TO-263.

FAQ

What is the maximum gate-source voltage rating for IPI45N06S4L08AKSA1?

The absolute maximum gate-source voltage is ±16 V. Operation beyond this risks permanent gate oxide damage. Recommended drive is 10 V for full R_DS(on) specification and 4.5 V for logic-level compatibility, with gate resistors selected to limit dV/dt-induced ringing during switching transitions.

Does IPI45N06S4L08AKSA1 require a heatsink in typical automotive applications?

Yes - even at 45 A continuous current, junction temperature exceeds safe limits without thermal management. With R_thJC = 2.1 K/W and typical R_thCS + R_thSA ≈ 1.5–3.0 K/W, a heatsink maintaining T_C ≤ 100 °C is required to hold T_j ≤ 175 °C under worst-case ambient conditions.

How does the body diode performance compare to external Schottky diodes?

The integrated body diode has V_SD = 0.95 V (typ.) and t_rr = 33 ns at 45 A, offering lower forward drop than most 45 A Schottkys but slower recovery. It eliminates discrete component count in non-critical freewheeling paths but is not recommended for high-frequency ZVS or PFC where ultrafast recovery is mandatory.

Is IPI45N06S4L08AKSA1 suitable for use in ISO 26262-compliant systems?

While not ASIL-certified as a standalone component, its AEC-Q101 qualification, 100% avalanche testing, and documented failure modes support inclusion in ASIL-B and ASIL-C system architectures when used with appropriate diagnostic coverage, redundancy, and layout-level fault mitigation per ISO 26262-5 Annex D.
