ATF521P8 Avago Technologies US Inc., ATF521P8 Datasheet - Page 21

• Manufacturer Part Number: ATF521P8
• Manufacturer: Avago Technologies US Inc.

Specifications of ATF521P8

• Configuration: Single Dual Source
• Drain-gate Voltage (max): -5 to 1V
• Operating Temperature (max): 150C
• Operating Temperature Classification: Military
• Mounting: Surface Mount
• Lead Free Status / Rohs Status: Compliant

Thus, for reliable operation of ATF‑521P8 and extended
MTBF, it is recommended to use some form of thermal
heatsinking. This may include any or all of the following
suggestions:
• Maximize vias underneath and around package;
• Maximize exposed surface metal;
• Use 1 oz or greater copper clad;
• Minimize board thickness;
• Metal heat sinks or extrusions;
• Fans or forced air;
• Mount PCB to Chassis.
