Schaltkreisschutz von Audioleitungen

Protection Application:: For audio circuits, the signal can have a maximum value of 5.5 Vp-p, and has a maximum frequency less than 30kHz. At this frequency, the capacitance of the suppressor does not need to be taken into account. The electrical threat is ESD.
Solution Description:: SPA TVS Diode Arrays or discrete diodes can be used for layout flexibility. In the upper schematic, a two-channel array is used to minimize part count. In the lower schematic two discrete 0201 diodes are used for flexibility and the smallest size parts.
Companion Solutions:: If the customer cannot use 0201 size diodes, then the SP1003-01DTG device can be considered.
Regulatory Issues:: 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.
