Littelfuse recommends a PCB layout with a large copper area connected to the thermal pad to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the thermal pad should be connected to a solid copper plane or a large copper pour.
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 217°C to 220°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 LCA701STR has a maximum surge current rating of 100 A, which is specified for a 10/1000 μs waveform. However, it's essential to note that the surge current rating may vary depending on the specific application and operating conditions.
While the LCA701STR is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz. However, the device's performance and characteristics may vary at higher frequencies, and additional testing and validation may be required.
During assembly and rework, the thermal pad should be handled carefully to avoid damaging the device. Littelfuse recommends using a thermal pad removal tool or a soldering iron with a thermal pad attachment to avoid applying excessive force or heat to the device.
