Product details

Overview

ISC046N04NM5ATMA1 from Infineon Technologies is an N-channel 40 V OptiMOSTM 5 power MOSFET in TDSON-8 FL package, featuring 4.6 mΩ max R_DS(on) at V_GS = 10 V, 77 A continuous drain current, 17 nC output charge, and 100% avalanche tested for robustness in high-current switching applications such as battery-powered motor drives.

For engineers reviewing the ISC046N04NM5ATMA1 datasheet, ISC046N04NM5ATMA1 pinout, ISC046N04NM5ATMA1 application, or ISC046N04NM5ATMA1 equivalent, key selection criteria include low conduction loss (R_DS(on) ≤ 4.6 mΩ), thermal resistance (R_thJC = 3 °C/W bottom-side), 175 °C rated junction temperature, and synchronous FET gate charge (Q_g(sync) = 14 nC) for high-efficiency DC-DC converters.

Technical Context

This device implements a trench-based silicon MOSFET architecture optimized for low R_DS(on) × Q_g figure-of-merit in synchronous buck topologies. Its TDSON-8 FL package features enlarged source interconnection for reduced parasitic inductance and enhanced current handling.

The MOSFET supports gate drive voltages from 4.5 V to 10 V, with a typical gate threshold voltage of 2.2–3.4 V and plateau voltage of 4.5 V. It delivers 32 mJ single-pulse avalanche energy and exhibits fast switching with t_d(on) = 4 ns, t_r = 2 ns, t_d(off) = 7 ns, and t_f = 3 ns under standard test conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRL40B215TRPBF	R_DS(on) = 3.2 mΩ (lower), but Q_g = 28 nC (higher); TO-252 package; R_thJA = 62 °C/W	Higher conduction efficiency but slower switching and poorer thermal performance on PCB	Prefer for low-frequency, high-current linear regulation where thermal mass dominates
BSC028N06NS3G	R_DS(on) = 2.8 mΩ, Q_g = 22 nC; 60 V rating; PG-TDSON-8 package with identical footprint	Higher voltage margin and slightly better FoM, but not qualified for 175 °C operation	Choose when system requires 60 V headroom or JEDEC industrial qualification is not mandatory

Compared with IRL40B215TRPBF and BSC028N06NS3G, ISC046N04NM5ATMA1 offers optimal balance of low R_DS(on), low Q_g, 175 °C rating, and industry-qualified thermal performance - making it preferred for compact, high-reliability 40 V synchronous buck and motor drive designs.

FAQ

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

The ISC046N04NM5ATMA1 supports 55 A continuous drain current at T_C = 100 °C with V_GS = 10 V, per Table 2 of the datasheet. This derating reflects thermal limits of the TDSON-8 FL package and must be validated against actual PCB layout and airflow conditions.

Does this MOSFET include an integrated body diode, and what are its key parameters?

Yes - it integrates a fast-recovery body diode with 50 A continuous forward current (I_S), 0.88 V typical forward voltage (V_SD) at 35 A and 25 °C, 30 ns reverse recovery time (t_rr), and 19 nC reverse recovery charge (Q_rr). These values are specified in Table 7 and support efficient freewheeling in synchronous rectification.

Can ISC046N04NM5ATMA1 be used in a high-side configuration with 12 V gate drive?

Yes - its V_GS(th) range (2.2–3.4 V) and guaranteed turn-on at V_GS ≥ 4.5 V make it fully compatible with 12 V gate drivers. The 20 V absolute maximum V_GS rating provides 2× safety margin, and the 4.5 V gate plateau voltage ensures stable enhancement-mode operation.

What is the significance of the "FL" suffix in TDSON-8 FL package?

The "FL" denotes "Full Leadframe" - indicating an enlarged source interconnection area within the TDSON-8 footprint. This design reduces source inductance and improves current distribution across pins S1–S3, directly enhancing switching performance and thermal transfer to the PCB copper plane.
