Product details

Overview

IPP45N06S3L-13 from Infineon Technologies is a 55 V, 45 A N-channel enhancement-mode MOSFET in PG-TO220-3-1 package, AEC-Q101 qualified for automotive applications, with R_DS(on) = 13.1 mΩ (max) at V_GS = 10 V and 100% single-pulse avalanche tested to 145 mJ. It operates up to 175 °C junction temperature and supports high-current DC/DC converters and motor control stages.

For engineers reviewing the IPP45N06S3L-13 datasheet, IPP45N06S3L-13 pinout, IPP45N06S3L-13 application, or IPP45N06S3L-13 equivalent, key selection criteria include its 2.3 K/W thermal resistance (junction-to-case), 50–75 nC total gate charge, 13.1 mΩ on-resistance, 180 A pulsed drain current capability, and integrated body diode with 20 ns reverse recovery time.

Technical Context

This OptiMOS®-T2 power transistor uses trench-gate superjunction technology optimized for low conduction and switching losses in hard-switched 12 V and 24 V automotive systems. Its gate threshold voltage (1.2–2.2 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity.

The device integrates a fast-recovery body diode (t_rr = 20 ns, Q_rr = 25 nC) and exhibits stable R_DS(on) over temperature (±30% drift from −55 °C to 175 °C), supporting reliable operation in engine bay and battery management environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum blocking voltage compatible with 48 V nominal battery systems and transient clamping to ISO 7637-2 Pulse 5a.
I_D (continuous)	45 A at T_C = 25 °C - Supports high-current load switching without external heatsink in moderate-duty cycles.
R_DS(on) max	13.1 mΩ at V_GS = 10 V - Enables <1.5 W conduction loss at 45 A, critical for thermally constrained under-hood modules.
E_AS	145 mJ - Confirmed single-pulse avalanche energy rating ensures ruggedness against inductive turn-off transients in motor drives.
Q_g	50–75 nC - Gate drive energy requirement defines minimum driver output current (≥2 A peak) for <100 ns switching transitions.
t_r/t_f	46 ns / 124 ns - Fast edge rates reduce switching losses but require careful PCB layout to suppress EMI in 100–500 kHz SMPS.
T_j max	175 °C - Enables operation in high-ambient environments such as EV traction inverters and starter-generator controllers.

Pinout & Package

IPP45N06S3L-13 is housed in PG-TO220-3-1 package: isolated tab (drain), vertical mounting, through-hole leaded configuration with standard TO-220 footprint and mechanical screw-down option for enhanced thermal transfer.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for channel current	Low-inductance source connection essential for minimizing shoot-through risk in half-bridge configurations.
Pin 2 (Gate)	Control terminal for channel modulation	High-impedance input requiring <100 pF gate loop capacitance to avoid oscillation during fast switching.
Pin 3 (Drain)	Main power output node (connected to tab)	Electrically connected to metal tab - must be isolated from chassis unless system design permits common-drain topology.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per JESD47.
100% avalanche tested	Each unit subjected to controlled single-pulse avalanche stress at I_D = 22.5 A, ensuring field reliability in inductive load switching.
MSL1 rating	Compatible with standard 260 °C peak reflow profiles - no moisture sensitivity handling required before assembly.
Green product (RoHS)	Lead-free termination and halogen-free mold compound compliant with EU Directive 2011/65/EU and IPC-1752A.
Optimized body diode	20 ns t_rr and 25 nC Q_rr enable synchronous rectification replacement in buck converters without external Schottky.

Applications

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) = 14.5 mΩ (max), Q_g = 65 nC, non-AEC-Q101	Lacks automotive qualification and 100% avalanche test; suitable for industrial but not safety-critical automotive use.	Select only for cost-sensitive non-automotive 12 V systems where AEC-Q101 is not mandated.
IRF4905ZPBF	55 V, 74 A, R_DS(on) = 11.5 mΩ, but P_tot = 110 W and TO-220AB package lacks isolated tab	Higher current rating but no isolation between drain and mounting surface - requires insulating hardware in grounded-chassis designs.	Prefer when higher continuous current is needed and thermal interface permits non-isolated mounting.

Compared with STP45NF06L and IRF4905ZPBF, IPP45N06S3L-13 uniquely combines AEC-Q101 compliance, isolated drain tab, and guaranteed 145 mJ avalanche energy - making it the only choice for production automotive power stages requiring functional safety alignment.

FAQ

Is IPP45N06S3L-13 pin-compatible with IPP45N06S3-13?

No. IPP45N06S3L-13 features an isolated drain tab and AEC-Q101 qualification, whereas IPP45N06S3-13 has a non-isolated tab and lacks automotive qualification. Mechanical mounting and safety certification differ - substitution requires redesign verification.

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

For 100 kHz hard-switching with 75 nC total gate charge, a 10 Ω gate resistor limits peak gate current to ~1 A and achieves ~100 ns turn-on delay. Values above 15 Ω increase switching losses significantly; below 5 Ω risks ringing without proper layout damping.

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

Yes. With t_rr = 20 ns and Q_rr = 25 nC, the body diode supports CCM operation up to 200 kHz in buck converters. However, efficiency gains over external Schottky depend on duty cycle and load current - verify with measured waveforms at target operating point.

Can IPP45N06S3L-13 replace IPP45N06S3H-13 in existing designs?

No. IPP45N06S3H-13 is a logic-level variant (V_GS(th) = 1.0–2.0 V) optimized for 3.3 V/5 V gate drive, while IPP45N06S3L-13 has standard threshold (1.2–2.2 V) and higher R_DS(on) at low V_GS. Substitution may cause incomplete turn-on and thermal runaway at 4.5 V drive.
