Product details

Overview

IAUC120N06S5L015ATMA1 from Infineon is an automotive-qualified N-channel enhancement-mode logic-level power MOSFET in PG-TDSON-8-43 package, rated for 60 V V_DS, 1.50 mΩ R_DS(on) at V_GS = 10 V, and 235 A chip-limited continuous drain current. It operates up to 175 °C junction temperature, supports 100% unclamped inductive avalanche testing, and is qualified per AEC-Q101 with MSL1 reflow capability.

For engineers reviewing the IAUC120N06S5L015ATMA1 datasheet, IAUC120N06S5L015ATMA1 pinout, IAUC120N06S5L015ATMA1 application, or IAUC120N06S5L015ATMA1 equivalent, key selection criteria include low R_DS(on) at 4.5 V gate drive, robust thermal performance (R_thJC = 0.90 K/W), and validated operation in high-reliability 12 V/48 V automotive power stages including battery disconnect and motor control.

Technical Context

This OptiMOS™-5 device uses trench-gate superjunction technology optimized for low conduction loss and fast switching in automotive DC-DC converters and high-current load switches. Its logic-level gate threshold (1.2–2.2 V) enables direct drive from microcontrollers, while its 1.6 Ω gate resistance and 88–114 nC total gate charge support controlled turn-on/turn-off timing under high di/dt conditions.

The MOSFET integrates a co-packaged body diode with 48 ns reverse recovery time and 48 nC Q_rr, enabling efficient synchronous rectification and freewheeling in bidirectional power paths. Its 36 mJ single-pulse avalanche energy rating ensures survivability during transient overvoltage events in 12 V starter-alternator and ADAS ECU applications.

FAQ

What is the maximum continuous drain current at T_C = 85 °C?

The maximum continuous drain current is 120 A at T_C = 85 °C with V_GS = 10 V and R_thJA defined on a 2s2p FR4 PCB. This rating reflects package-limited current handling under realistic board-level thermal conditions-not chip-limited capability-and must be verified against actual PCB copper area and airflow in the target application.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor is recommended to control dV/dt and suppress ringing during switching. With 1.6 Ω intrinsic gate resistance and 88–114 nC total gate charge, a 5–10 Ω external resistor typically achieves optimal trade-off between switching speed (t_r/t_f ≈ 6/24 ns) and EMI suppression in 48 V automotive inverters.

Is the body diode suitable for synchronous rectification?

Yes-the integrated body diode has 48 ns reverse recovery time and 48 nC Q_rr at T_j = 25 °C, making it suitable for synchronous rectification in 100–200 kHz DC-DC converters. However, forward voltage (V_SD = 0.8–1.1 V at 60 A) is higher than discrete Schottky diodes, so efficiency gain depends on duty cycle and thermal management.

How does the MSL1 rating impact assembly process design?

MSL1 rating means the device can withstand peak reflow temperatures up to 260 °C without baking or special handling, fully compatible with standard J-STD-020-compliant lead-free SMT processes. No moisture sensitivity precautions are required, simplifying logistics and eliminating bake-out steps in high-volume automotive PCBA lines.
