Product details

Overview

IPB45N06S3L-13 from Infineon Technologies is an N-channel enhancement-mode automotive-grade power MOSFET in PG-TO263-3-2 package, rated for 55 V V_DS, 45 A continuous drain current at T_C = 25 °C, and 13.1 mΩ max R_DS(on) at V_GS = 10 V. It is AEC-Q101 qualified, 100% avalanche tested, and operates up to 175 °C - deployed in high-reliability DC-DC converters and motor control stages in engine management systems.

For engineers reviewing the IPB45N06S3L-13 datasheet, IPB45N06S3L-13 pinout, IPB45N06S3L-13 application, or IPB45N06S3L-13 equivalent, key selection criteria include its 2.3 K/W junction-to-case thermal resistance, 145 mJ single-pulse avalanche energy, gate plateau voltage of 4.9 V, and SMD-compatible TO263 footprint for thermally demanding automotive power stages.

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its 430 pF reverse transfer capacitance (Crss) and 50–75 nC total gate charge support fast, controlled turn-on/turn-off with minimal Miller-induced shoot-through risk.

The integrated body diode exhibits 0.9 V typical forward voltage at 25 A and 20 ns reverse recovery time under defined test conditions (V_R = 27.5 V, di/dt = 100 A/µs), enabling efficient synchronous rectification and freewheeling in buck and half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - maximum blocking voltage compatible with 48 V automotive battery transients and 12 V/24 V system rails
R_DS(on) max	13.1 mΩ at V_GS = 10 V - enables <1.5 W conduction loss at 45 A, reducing heatsink requirements
I_D continuous	45 A at T_C = 25 °C - supports high-current load switching without derating in forced-air-cooled modules
E_AS	145 mJ single-pulse - withstands inductive energy dump during fault events in motor drivers and solenoid controls
Q_g total	50–75 nC - determines gate driver power requirement and switching speed trade-off in PWM applications
T_j max	175 °C - allows operation in under-hood environments without thermal shutdown in engine control units
R_thJC	2.3 K/W - defines minimum thermal interface resistance needed between die and heatsink for safe power dissipation

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP45N06S3L-13	Same die, PG-TO220-3-1 through-hole package; R_thJA = 62 K/W (leaded), no exposed thermal pad	Better suited for prototyping or low-volume manual assembly; less effective thermal performance in high-power density designs	Select when board space allows larger footprint and thermal management relies on heatsink mounting rather than PCB copper area
IPI45N06S3L-13	Same die, PG-TO262-3-1 package; R_thJA = 62 K/W (leaded); identical marking (3N06L13)	Intermediate thermal solution - pin-compatible with TO220 but surface-mountable; requires clip or screw-down heatsink	Choose for automated SMT assembly where TO263 thermal pad layout is impractical but higher power density than TO220 is required

Compared with IPP45N06S3L-13 and IPI45N06S3L-13, the IPB45N06S3L-13 delivers superior thermal performance via its exposed drain pad and 2.3 K/W R_thJC, making it optimal for space-constrained, high-power automotive modules where PCB copper area is used as heatsink.

FAQ

Is IPB45N06S3L-13 suitable for 48 V mild-hybrid systems?

No - its 55 V V_DS rating provides only 7 V margin above nominal 48 V bus, insufficient for ISO 16750-2 load-dump transients (up to 65 V). For 48 V systems, Infineon's 80 V OptiMOS™ 5 devices such as IPB80N04S4-02 are recommended.

What is the maximum gate resistor value for reliable switching at 250 kHz?

With Q_g = 62.5 nC (typical) and t_r/t_f targets ≤50 ns, a 10 Ω gate resistor is recommended when driven by a ±4 A capable driver. Higher values increase switching losses and risk shoot-through in bridge configurations.

Does the body diode support synchronous rectification in continuous conduction mode?

Yes - its 20 ns t_rr and 25 nC Q_rr allow use as a freewheeling diode in CCM buck converters up to ~150 kHz, though external Schottky diodes may be preferred for ultra-low V_SD in high-frequency designs.

Can IPB45N06S3L-13 replace IPP45N06S3L-13 on the same PCB?

No - PG-TO263-3-2 (IPB) and PG-TO220-3-1 (IPP) have incompatible footprints and thermal pad layouts. Direct replacement requires PCB redesign to accommodate the exposed drain pad and smaller outline of the TO263 package.
