Overview
The ESDA5V3L is a 5.3 V bidirectional TVS (Transil) diode array designed by STMicroelectronics to protect sensitive electronics against electrostatic discharge (ESD) and voltage transients. This device is ideal for applications where both reduced line capacitance and board space saving are critical. It can protect one or two lines against ESD transients and can also be used as a bidirectional suppressor by connecting only pins 1 and 2.
