Description
The ASL05C is a low capacitance TVS diode array, utiliz-
ing leading monolithic silicon technology to provide fast
response time and low ESD clamping voltage, making
this device an ideal solution for protecting sensitive semi-
conductor components from damage. The ASL05C com-
plies 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 high speed interfaces and trans-
mission lines from voltage surges.
