Part Details for V33ZA70PX1347 by Littelfuse Inc

Littelfuse recommends a PCB layout with a large copper area connected to the thermal tab to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.

To ensure reliable soldering, Littelfuse recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 180°C to 190°C. The component should be soldered within 3 seconds to 5 seconds, and the solder joints should be inspected for proper wetting and filleting.

The V33ZA70PX1347 has a maximum surge current rating of 100 A for 10 ms, as specified in the datasheet. However, it's essential to note that the device can handle higher surge currents for shorter durations, but this should be verified through simulation or testing.

While the V33ZA70PX1347 is a high-quality device, it may not meet the specific requirements for high-reliability or aerospace applications. Littelfuse offers other products that are specifically designed and qualified for these applications, such as the SP1333 or the PSR series. It's recommended to consult with Littelfuse or a qualified distributor for guidance on selecting the appropriate device.

To determine the correct fuse rating, you should consider factors such as the maximum expected current, the fault current, and the operating temperature. Littelfuse provides a fuse selection guide and online tools to help engineers select the appropriate fuse rating for their application.
