Circuit Protection of Hard Disk Drive

解决方案：

保护申请：: 对于内部硬盘驱动器，该驱动器位于应用程序底盘内。这排除了用户与数据总线联系，因此ESD预计不会成为威胁。在电源总线（通常为3.3VDC至12VDC）上，威胁将是电涌瞬变，ESD和过载电流。
解决方案说明：: As shown at the left, an SMD chip fuse can be used for overload current protection, and a TVS diode or MLV for surge transients and ESD protection. The specific part numbers are determined by matching the power bus operating voltage to that of the suppressor.
伴侣解决方案：: 不适用。
监管问题：: The IEC 61000-4-2 will be the most appropriate standard that applies for this port. It supplies a test method for verifying that the end product is not susceptible to ESD events.
Unique Features:: 不适用。
申请警告：: 不适用。
