Product details

Overview

IPP45N06S409AKSA1 from Infineon Technologies is a 60 V, 45 A N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, optimized for automotive and industrial switching applications with 9.2 mΩ max R_DS(on) at V_GS = 10 V, 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 primary-side switching.

For engineers reviewing the IPP45N06S409AKSA1 datasheet, IPP45N06S409AKSA1 pinout, IPP45N06S409AKSA1 application, or IPP45N06S409AKSA1 equivalent, key selection criteria include R_DS(on) stability over temperature, single-pulse avalanche energy (97 mJ), thermal resistance (R_thJC = 2.1 K/W), gate charge profile (Q_g = 36–47 nC), and diode forward voltage (V_SD = 0.6–1.3 V).

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching performance. Its 7.9 mΩ typical R_DS(on) at 45 A/10 V and 30 ns total switching time (t_d(on) + t_r + t_d(off) + t_f) enable high-efficiency operation in hard-switched topologies.

The integrated body diode exhibits low reverse recovery charge (Q_rr = 40 nC) and fast t_rr (45 ns), reducing commutation losses in synchronous rectification and half-bridge configurations. Gate threshold voltage (2.0–4.0 V) ensures stable turn-on under noisy automotive supply conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-source blocking voltage for 12 V/24 V automotive and 48 V industrial bus systems.
R_DS(on), max	9.2 mΩ at V_GS = 10 V, I_D = 45 A - Enables ≤2.1 W conduction loss at full rated current, critical for thermally constrained enclosures.
I_D, continuous	45 A at T_C = 25 °C - Sustained current rating defined by bondwire limit, not silicon thermal saturation.
E_AS	97 mJ at I_D = 22.5 A - Confirmed single-pulse avalanche ruggedness for inductive load switching without external snubbers.
Q_g	36–47 nC - Determines gate driver power requirement and switching speed trade-off in PWM frequency range 20–100 kHz.
V_GS(th)	2.0–4.0 V - Ensures reliable turn-on with standard 5 V logic-level drivers and noise margin against false triggering.
t_rr	45 ns - Limits diode reverse recovery loss during high-frequency bridge transitions, supporting >50 kHz operation.

Pinout & Package

IPP45N06S409AKSA1 is housed in PG-TO220-3-1 package: isolated tab, vertical mounting, through-hole leaded configuration with 2.1 K/W junction-to-case thermal resistance. The drain-connected tab enables direct heatsink attachment for high-power dissipation.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Reference node for gate drive; connects to low-side return path and PCB ground plane.
Pin 2 (Gate)	Control input	High-impedance MOSFET gate requiring <100 nA leakage current; sensitive to ESD and layout parasitics.
Pin 3 (Drain)	Power output	Internally connected to metal tab; must be electrically isolated from heatsink unless system design permits common-drain topology.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and UHAST.
100% avalanche tested	Each unit subjected to single-pulse avalanche stress at rated I_AS = 45 A, ensuring field reliability in inductive fault conditions.
Green Product (RoHS)	Lead-free termination and halogen-free molding compound compliant with EU Directive 2011/65/EU and IPC-1752.
175 °C operating temperature	Junction temperature rating allows operation in engine bay or industrial motor drive enclosures without derating below full current.
Low Q_gd/Q_gs ratio	Typical 4–8 nC / 17–22 nC = ~0.35 - Improves Miller immunity and reduces risk of shoot-through in bridge circuits.

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
STP45NF06L	R_DS(on) = 14 mΩ (max), lower V_GS(th) (1–2.5 V), no AEC-Q101 certification	Not qualified for automotive use; suitable only for industrial/commercial non-safety-critical designs	Select when cost sensitivity outweighs automotive compliance and higher R_DS(on) is acceptable.
IRFZ44NPBF	R_DS(on) = 28 mΩ (max), 55 V rating, TO-220AB package, no avalanche testing	Limited to 12 V/24 V low-power loads; unsuitable for 48 V systems or repetitive inductive switching	Choose only for legacy designs where footprint compatibility is mandatory and current demand ≤20 A.

Compared with STP45NF06L and IRFZ44NPBF, IPP45N06S409AKSA1 provides superior thermal performance (2.1 K/W vs. ≥3.0 K/W), guaranteed avalanche ruggedness, and automotive-grade reliability-making it the preferred choice for mission-critical 45 A switching where efficiency, safety, and lifetime are prioritized over lowest unit cost.

FAQ

What is the maximum allowable gate-source voltage for IPP45N06S409AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this rating risks permanent gate oxide damage. Recommended drive voltage is 10 V for full R_DS(on) specification; 5 V is insufficient for guaranteed turn-on due to V_GS(th) upper limit of 4.0 V. Gate resistors must be selected to limit dV/dt-induced ringing within safe SOA limits.

Does IPP45N06S409AKSA1 require a heatsink in continuous 45 A operation?

Yes. At 45 A and 10 V V_GS, conduction loss is ~16 W (I² × R_DS(on)). With R_thJC = 2.1 K/W and typical R_thCA > 40 K/W for TO-220 in still air, junction temperature exceeds 175 °C without a heatsink. A minimum 25 cm² aluminum heatsink with thermal interface material is required to maintain T_j ≤ 150 °C at 25 °C ambient.

Can IPP45N06S409AKSA1 replace IPP45N06S409 in existing designs?

Yes-IPP45N06S409AKSA1 is the updated tape-and-reel variant of IPP45N06S409, sharing identical electrical specifications, thermal characteristics, and mechanical dimensions. The "KSA1" suffix denotes packaging format (tape-and-reel, RoHS-compliant, MSL1) and does not affect performance or pin compatibility.

Is the body diode suitable for synchronous rectification in a buck converter?

It can be used but is suboptimal. While V_SD = 0.6–1.3 V and t_rr = 45 ns meet basic requirements, its Q_rr = 40 nC is higher than dedicated synchronous rectifier MOSFETs. For >90% efficiency at high load, a discrete Schottky or optimized low-Q_rr MOSFET is recommended on the low-side leg.
