Overview
The ESDA37L is a diode array designed by STMicroelectronics to protect one or two lines against Electrostatic Discharge (ESD) transients. This device is particularly suited for applications where reduced line capacitance and board space saving are essential. It can also be configured as a bidirectional suppressor by connecting only pins 1 and 2.
