Overview: DATA SHEET .onsemi. ESD Protection Diode
Ultra−Low Capacitance
ESDR0502B, SZESDR0502B The ESDR0502B is designed to protect voltage sensitive ponents from damage due to ESD in applications that require ultra low capacitance to preserve signal integrity. Excellent clamping capability, low leakage and fast response time are bined with an ultra low diode capacitance of 0.5 pF to provide best in class protection from IC damage due to ESD. The small SC−75 package is ideal for designs where board space is at a premium. The ESDR0502B can be used to protect two uni−directional lines or one bi−directional line. When used to protect one bi−directional line, the effective capacitance is 0.25 pF. Because of its low capacitance, it is well suited for protecting high frequency signal lines such as USB2.0 high speed and antenna line applications.
