Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow this layout to ensure proper device operation and to minimize thermal resistance.
Bourns offers a range of fuse holders and clips compatible with the GMOV-20D151K. Engineers should consult the Bourns website or contact their local distributor to select the appropriate fuse holder or clip based on their specific application requirements.
The maximum allowable voltage drop across the GMOV-20D151K is not explicitly stated in the datasheet. However, as a general rule, it's recommended to keep the voltage drop below 1V to ensure reliable operation and to prevent excessive heat generation.
The GMOV-20D151K is rated for operation up to 125°C. However, engineers should consider the derating curves provided in the datasheet and ensure that the device is properly cooled to prevent overheating and premature failure.
To determine the correct fuse rating, engineers should consider the maximum current and voltage in their application, as well as the required response time and fault current. Bourns provides a fuse selection guide and application notes that can help with this process.
