Product details

Overview

IPP45N06S409AKSA2 from Infineon Technologies is a 60 V, 45 A N-channel enhancement-mode MOSFET in PG-TO220-3-1 package, optimized for automotive and industrial switching applications with 9.2 mΩ max R_DS(on), 100% avalanche tested, and AEC-Q101 qualified. It delivers high pulsed current capability (180 A), operates up to 175 °C junction temperature, and supports robust motor control and DC-DC converter designs.

For engineers reviewing the IPP45N06S409AKSA2 datasheet, IPP45N06S409AKSA2 pinout, IPP45N06S409AKSA2 application, or IPP45N06S409AKSA2 equivalent, key selection criteria include R_DS(on) at 10 V gate drive, thermal resistance (R_thJC = 2.1 K/W), avalanche energy rating (97 mJ), and automotive qualification status.

Technical Context

This OptiMOS®-T2 power transistor uses trench-gate superjunction technology to achieve low conduction loss and fast switching with controlled gate charge (Q_g = 36–47 nC). Its 7.9–9.4 mΩ typical R_DS(on) at V_GS = 10 V and I_D = 45 A enables high-efficiency operation in hard-switched topologies.

The device integrates a robust body diode with 0.6–1.3 V forward voltage (V_SD) and 40–60 ns reverse recovery time (t_rr). Thermal design is supported by a low junction-to-case resistance of 2.1 K/W and MSL1 reflow compatibility up to 260 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-source blocking voltage for 12 V/24 V automotive and industrial bus systems.
R_DS(on), max	9.2 mΩ - Ensures ≤2.1 W conduction loss at 45 A continuous drain current with 10 V gate drive.
I_D, cont	45 A - Sustained current capability at T_C = 25 °C, limited by bondwire; derates to 45 A at T_C = 100 °C.
E_AS	97 mJ - Single-pulse avalanche energy at I_D = 22.5 A supports unclamped inductive switching reliability.
R_thJC	2.1 K/W - Enables direct heatsink mounting for thermal management in high-power linear or switching modes.
Q_g	36–47 nC - Gate charge range determines driver strength requirement for <50 ns turn-on/turn-off times.
t_r/t_f	40 ns / 5 ns - Fast switching transitions reduce switching losses in 100–500 kHz SMPS and motor gate drivers.

Pinout & Package

IPP45N06S409AKSA2 is housed in a PG-TO220-3-1 package with through-hole mounting, isolated tab (drain-connected), and standard three-terminal layout. The case is electrically connected to the drain, requiring proper insulation when mounted to heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Receives 10 V logic-level gate drive; threshold voltage 2.0–4.0 V ensures reliable turn-on with standard microcontroller outputs.
2 (Drain)	High-side switch node	Connected to package tab; carries full load current and must be insulated from heatsink unless referenced to system ground.
3 (Source)	Power return path	Serves as reference for gate drive and current sensing; low-inductance layout critical for EMI control in high-di/dt applications.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and UHAST.
100% avalanche tested	Each unit undergoes single-pulse avalanche stress to guarantee minimum 97 mJ energy handling without degradation.
175 °C operating temperature	Enables use in under-hood environments and sealed industrial enclosures without derating below rated current.
Green Product (RoHS)	Lead-free termination and halogen-free mold compound compliant with EU Directive 2011/65/EU and IPC-1752A.
MSL1 reflow rating	Withstands peak soldering temperatures up to 260 °C, supporting automated assembly in high-reliability manufacturing lines.

FAQ

Is IPP45N06S409AKSA2 pin-compatible with other OptiMOS®-T2 45 A variants?

Yes-IPP45N06S409AKSA2 shares identical pinout (G-D-S) and footprint with IPB45N06S409AKSA2 and IPI45N06S409AKSA2. However, package differences (TO-220 vs. TO-263 vs. TO-262) affect mechanical mounting, thermal interface, and PCB layout. Electrical characteristics are identical across all three part numbers.

What is the maximum recommended gate resistor value for 100 kHz switching?

For 100 kHz operation with minimal switching loss, a gate resistor of 3.5 Ω is validated in the datasheet (t_d(on) = 15 ns, t_r = 40 ns). Using >10 Ω increases turn-on time and conduction overlap loss; <2 Ω risks ringing and EMI without proper PCB layout damping.

Does the body diode support synchronous rectification in buck converters?

The integrated body diode has V_SD = 0.6–1.3 V and t_rr = 45 ns, making it usable for non-synchronous rectification. For synchronous operation, external Schottky or MOSFETs are preferred due to higher forward drop and recovery charge (Q_rr = 40 nC), which increases losses above 100 kHz.

Can IPP45N06S409AKSA2 replace older OptiMOS®-T1 devices in existing designs?

Yes-IPP45N06S409AKSA2 offers lower R_DS(on) (9.2 mΩ vs. ~12 mΩ for T1), improved avalanche rating, and tighter V_GS(th) distribution. No layout changes are needed, but gate drive strength should be verified due to higher Q_g (36–47 nC vs. ~28 nC).
