Description
The ASM712Y is designed for asymmetrical (12V to –7V)
protection in multi-point data transmission application,
The ASM712Y replace four discrete components by integrating two 12V and two 7V TVS diodes in a single package. The ASM712Y complies with the IEC 61000-4-2
(ESD) with ±30kV air and ±30kV contact discharge. It is
assembled into a lead-free SOT-23 package. It is designed to protect components which are connected to
data and transmission lines from voltage surges.
