Product details
Overview
IPI45N06S409AKSA2 from Infineon Technologies is an AEC-Q101-qualified N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, rated for 60 V VDS, 45 A continuous drain current at TC = 25 °C, and 9.2 mΩ max RDS(on) at VGS = 10 V. It operates up to 175 °C junction temperature, features 100% single-pulse avalanche testing (97 mJ), and is used in automotive DC-DC converters and motor control half-bridges.
For engineers reviewing the IPI45N06S409AKSA2 datasheet, IPI45N06S409AKSA2 pinout, IPI45N06S409AKSA2 application, or IPI45N06S409AKSA2 equivalent, key selection criteria include RDS(on) stability over temperature, avalanche ruggedness under inductive switching, thermal resistance (RthJC = 2.1 K/W), and AEC-Q101 qualification for automotive power stages.
Technical Context
This MOSFET employs Infineon's OptiMOS™-T2 silicon technology optimized for low conduction and switching losses in 12 V/24 V automotive systems. Its gate threshold voltage (2.0–4.0 V) enables robust drive with standard 5 V or 10 V logic-level controllers, while its 36–47 nC total gate charge supports efficient high-frequency PWM operation up to 100 kHz.
The device integrates a fast-recovery body diode (trr = 45 ns, Qrr = 40 nC) suitable for synchronous rectification and freewheeling in buck, boost, and H-bridge topologies. Thermal design is enabled by its low junction-to-case resistance (2.1 K/W) and compatibility with standard TO-220 footprint PCB layouts using 6 cm² copper area for enhanced heat dissipation.
Key Specifications

FAQ
What is the maximum allowable gate-source voltage for IPI45N06S409AKSA2?
The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent oxide damage. Recommended drive is 10 V for full enhancement with margin; 5 V is insufficient for low RDS(on) in production use. Gate drive circuits must include clamping (e.g., 15 V Zener) to prevent transients from exceeding this limit during hot-plug or load dump events.
Does IPI45N06S409AKSA2 require a gate resistor, and what value is recommended?
Yes - a gate resistor is mandatory to control dV/dt and prevent oscillation. For 45 A switching at 20–100 kHz, a 4.7 Ω to 10 Ω series resistor is recommended. Lower values increase switching speed but risk shoot-through in half-bridge configurations; higher values reduce EMI but raise switching losses. Layout parasitics must be minimized regardless of resistor choice.
How does the body diode performance compare to discrete Schottky diodes in freewheeling applications?
The integrated body diode has VSD = 0.6–1.3 V and trr = 45 ns, making it suitable for medium-frequency freewheeling but less efficient than 0.45 V Schottky diodes at high current. Its advantage lies in co-packaged integration, eliminating layout complexity and parasitic inductance. For >100 kHz or >95% efficiency targets, external Schottky remains preferred.
Is IPI45N06S409AKSA2 suitable for linear-mode (LDO-like) operation?
No - it is not characterized or qualified for linear-mode operation. Safe Operating Area (SOA) curves show limited DC capability below 10 V VDS; prolonged operation in the linear region causes localized thermal runaway due to positive temperature coefficient of RDS(on). It must be operated in saturated switch mode only, with adequate heatsinking and strict duty-cycle limits if pulsed.
