Product details

Overview

IPI100N10S305AKSA1 from Infineon Technologies is a 100 V, 100 A N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, AEC-Q101 qualified for automotive applications, with R_DS(on) max of 4.8 mΩ at V_GS = 10 V and 100 A, 175 °C maximum junction temperature, and 100% avalanche tested - used in high-current DC-DC converters and motor control inverters.

For engineers reviewing the IPI100N10S305AKSA1 datasheet, IPI100N10S305AKSA1 pinout, IPI100N10S305AKSA1 application, or IPI100N10S305AKSA1 equivalent, key selection criteria include its 0.5 K/W thermal resistance (junction-to-case), 1445 mJ single-pulse avalanche energy, gate plateau voltage of 5.5 V, SMD-compatible TO262 footprint, and automotive-grade reliability validation.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology to achieve low R_DS(on) × Q_g figure-of-merit (4.8 mΩ × 176 nC), enabling high-efficiency switching in hard-switched topologies. Its gate threshold voltage range (2.0–4.0 V) ensures robust noise immunity while supporting standard 10 V gate drive.

The MOSFET integrates an optimized body diode with 108 ns reverse recovery time and 380 nC Q_rr, reducing commutation losses in synchronous rectification and half-bridge configurations. Thermal design is supported by MSL1 rating (260 °C peak reflow) and validated 175 °C continuous operation.

Key Specifications

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
IPP100N10S3-05	Same die, PG-TO220-3-1 package; R_thJA = 62 K/W (vs. 40 K/W for SMD variant)	Better suited for prototyping and low-volume manual assembly; lower thermal performance in high-power density layouts	Select when board space permits larger through-hole footprint and thermal management relies on heatsink clamping
IPB100N10S3-05	Same die, PG-TO263-3-2 (D²PAK) package; identical R_DS(on), but 20 % higher C_iss (11570 pF vs. 11570 pF typical)	Preferred for automated SMT lines with standard D²PAK pick-and-place; slightly higher gate drive loss	Select for volume production where D²PAK reflow compatibility and IPC-compliant land patterns are required

Compared with IPP100N10S3-05 and IPB100N10S3-05, IPI100N10S305AKSA1 offers optimal thermal resistance (R_thJC = 0.5 K/W) and mechanical fit for high-reliability TO262-based power modules, balancing manufacturability, thermal performance, and automotive qualification.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The IPI100N10S305AKSA1 supports 100 A continuous drain current at T_C = 100 °C and V_GS = 10 V, limited by bondwire capacity rather than silicon thermal saturation. This rating assumes proper PCB copper area (≥6 cm² drain pad) and adequate airflow or heatsinking to maintain case temperature.

Is this MOSFET suitable for synchronous rectification in LLC resonant converters?

Yes - its body diode exhibits t_rr = 108 ns and Q_rr = 380 nC at 25 °C, enabling low-loss freewheeling with minimal voltage overshoot. Combined with low R_DS(on) and fast switching (t_r/t_f ≤ 20 ns), it delivers high secondary-side efficiency in 100–300 kHz LLC designs.

Does the device require gate resistors for reliable switching?

A gate resistor of 3.5 Ω is specified in the datasheet for characterization (V_DD = 80 V, I_D = 100 A). For production use, 2.2–4.7 Ω is recommended to balance switching speed, gate oscillation damping, and driver stress - especially critical in paralleled configurations or high-dV/dt environments.

How does the 175 °C maximum junction temperature impact system design?

The 175 °C rating allows operation in under-hood automotive environments without active cooling, enabling smaller heatsinks and reduced system weight. It also extends safe operating area (SOA) at elevated temperatures, permitting higher pulse currents during transient overload conditions without thermal shutdown.
