Infineon ISC Series Power Transistor, 234W Maximum Power Dissipation, 40V Maximum Drain Source Voltage - ISCH42N04LM7ATMA1


This power transistor is a high-current N‑channel enhancement-mode MOSFET designed for demanding power-conversion and switching roles. It operates across a broad temperature span for use in thermally challenging environments and is supplied in an 8-pin surface-mount TDSON package suited to compact board layouts.

Features and Benefits:


• 234W power dissipation enables sustained high-power operation
• 541A continuous drain current supports heavy current loads
• 40V drain‑source rating allows medium-voltage system compatibility
• 0.42mΩ Rds(on) minimises conduction losses during switching
• 79nC typical gate charge reduces switching energy in fast designs
• 1V forward voltage lowers loss in synchronous rectification

Applications


• Suitable for high-current motor drive stages
• Ideal for server and data-centre power rails
• Used with DC-DC converters in telecom equipment
• Can be used for synchronous rectifiers in power supplies
• Employed in industrial inverter output stages

What thermal extremes can it withstand during operation?


The device is specified to function from -55°C up to 175°C, allowing use in applications with wide ambient or junction temperature variations.

How is the package optimised for PCB assembly?


The PG‑TDSON‑8 surface-mount package offers low thermal resistance and compact footprint for automated assembly on densely populated boards.

What gate drive considerations are relevant for fast switching?


With a typical gate charge of 79nC and a maximum Vgs of 20V, designers should size driver current to manage charge/discharge times while staying within gate-voltage limits.

Are there constraints on current handling in sustained operation?


Continuous drain current of 541A indicates high steady-state capability but requires appropriate thermal management to maintain specified power dissipation.
