Bel Fuse recommends a PCB layout with a solid ground plane and a thermal pad connected to the ground plane to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the device and the heat sink.
To ensure reliable operation in high-vibration environments, Bel Fuse recommends securing the device using a screw or clip, and using a potting compound to fill any gaps between the device and the PCB. Additionally, the PCB should be designed to minimize flexure and vibration transmission to the device.
Bel Fuse recommends derating the maximum voltage by 10-15% to ensure reliable operation and to account for voltage spikes and transients. For example, if the maximum rated voltage is 20V, the derated voltage would be 17-18V.
The SLIN-20E1AL is rated for operation up to 125°C. However, Bel Fuse recommends derating the current and voltage ratings at higher temperatures to ensure reliable operation. Consult the datasheet and Bel Fuse application notes for specific derating guidelines.
Bel Fuse recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a ramp rate of 3-4°C/second. The device should be soldered using a lead-free solder alloy, such as SAC305.
