Description
The ASLXX 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 ASLXX 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.
Features
• 300W peak pulse power (8/20μs)
• Two devices protect one line
• Ultra low leakage: nA level
• Operating voltage: 5V, 12V, 24V,36V
• Low capacitance for high-speed data line
• Low clamping voltage
• Complies with following standards:
– IEC 61000-4-2 (ESD) immunity test
Air discharge: ±30kV
Contact discharge: ±30kV
• RoHS Compliant
