AUIRF540ZSTRL

AUIRF540ZSTRL Description

The AUIRF540ZSTRL from Infineon Technologies is an N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a 100V drain-to-source voltage (Vdss) and 36A continuous drain current (Id), this device delivers robust performance in demanding environments. Its low on-resistance (Rds(on)) of 26.5mΩ @ 10V, 22A minimizes conduction losses, while the high gate charge (Qg) of 63nC @ 10V ensures fast switching capabilities. Packaged in a D2PAK (TO-263) surface-mount format and supplied in Tape & Reel (TR), it is optimized for automated assembly. Though marked Obsolete, it remains a reliable choice for legacy designs requiring high-current handling and thermal efficiency.

AUIRF540ZSTRL Features

• Low Rds(on): 26.5mΩ @ 10V, reducing power dissipation and improving efficiency.
• High Current Capacity: 36A continuous drain current (Tc) for heavy-load applications.
• Fast Switching: Gate charge (Qg) of 63nC @ 10V enables rapid turn-on/off transitions.
• Robust Voltage Handling: 100V Vdss and ±20V Vgs(max) tolerance for versatile use.
• Thermal Performance: 92W power dissipation (Tc) ensures reliability under high thermal stress.
• Compliance: ROHS3 and REACH unaffected, with MSL 1 (unlimited) shelf life.

AUIRF540ZSTRL Applications

Ideal for DC-DC converters, motor drives, and power supplies, the AUIRF540ZSTRL excels in:
