ST0521D2
1-Line Ultra Low Capacitance Bi-directional TVS Diode
Description
Mechanical Characteristics
The ST0521D2 is a bi-directional TVS diode, utilizing leading
monolithic silicon technology to provide fast response time and
low ESD clamping voltage, making this device an ideal solu-
tion for protecting voltage sensitive high-speed data lines. The
ST0521D2 has an ultra-low capacitance with a typical value at
0.26pF, and complies with the IEC 61000-4-2 (ESD) standard
with ±15kV air and ±8kV contact discharge. It is assembled
into an ultra-small 0.6x0.3x0.3mm lead-free DFN package. The
small size, ultra-low capacitance and high ESD surge protec-
tion make ST0521D2 an ideal choice to protect cell phone,
digital video interfaces and other high speed ports.
