Littelfuse recommends a thermal pad on the bottom of the device, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
Littelfuse recommends using a soldering iron with a temperature of 250°C to 260°C, and a solder with a melting point of 180°C to 190°C. The device should be soldered within 3 seconds to 5 seconds, and the solder fillet should be smooth and shiny.
The S402ES has a maximum surge current rating of 100 A, 8/20 μs waveform, as per IEC 61000-4-5. This rating is based on the device's ability to withstand high-current surges without failing.
Yes, the S402ES is rated for operation up to 150°C, making it suitable for high-temperature applications. However, the device's performance and reliability may degrade at elevated temperatures, so it's essential to consult the datasheet and application notes for specific guidance.
Littelfuse recommends using a fuse holder or clip that is specifically designed for the S402ES. The holder or clip should provide a secure connection, ensure proper alignment, and meet the device's electrical and thermal requirements.
