MB6A /RZ&DSDFLWDQFH 6XSHU/RZ&ODPSLQJ9ROWDJH 7UDQVLHQW9ROWDJH6XSSUHVVRUV Series MERITEK $EVWUDFW It describes characteristics’ advantage of MB6A, structure graphics, compliant to surge standard test system, electrical characteristics index, 6KV lightning surge comparing test and related application. .H\ZRUGV SMB package, clamping voltage, comparing test, placement graphics MB6A is a component of low profile package (SMB) and low capacitance instead of plated axial lead package SAC. It is easier for surface mounted using SMT machine. It has several advantages such as responding less than 1 picosecond, low clamping voltage and super low capacitance. Compared to TSS P0080SX series products which have disadvantage of high clamping voltage, MB6A can protect the next circuit directly. MB6A’s only disadvantage is that we should use two of them paralleled for bidirectional protection because it is unidirectional structure TVS. Because MB6A responds very rapidly and lower clamping voltage, low capacitance, it is ideal for protecting communication I/O data line which has high frequency.
