Overview
The ESDA7P120-1U1M is a transient voltage suppressor (TVS) diode from STMicroelectronics, designed to protect sensitive electronics from electrical overstress (EOS), lightning surges, and electrostatic discharge (ESD) in harsh environments. This component is part of the ESDAxxPxxx-1U1M series, which offers high peak pulse power, low leakage current, and fast turn-on times. The ESDA7P120-1U1M is packaged in a compact 1.6 mm x 1.0 mm QFN-2L footprint, making it ideal for space-constrained applications.
