The SMDJ36CA-AT is a bidirectional Electrostatic Discharge (ESD) protection diode manufactured by Yageo. It is housed in the SMC (DO-214AB) RoHS package which is meant for surface mount applications and is compliant with the European Union's Restriction of Hazardous Substances (RoHS). It is designed for secondary lightning surge protection and has an IEC rating of 600W. The SMDJ36CA-AT offers a maximum peak pulse current of 36A. The stand-off voltage matches up to 5.7V and break-over voltage of 16.6V. The Thermal Resistance Junction-to-Case (R?JC) is 5.9°C/W. The leakage current measured at 5.7V is 11µA. The SMDJ36CA-AT offers a low thermal performance, high junction capacitance and a thermal protection mechanism.
