The SMAJ160A with 259V 178V 160V Unidirectional SMA TVS ROHS manufactured by Yongyutai Electronics is a Surface Mount Transient Voltage Suppressor (TVS) device designed to protect electronics from voltage spikes greater than normal power-supply voltage. It offers unidirectional overvoltage protection for sensitive components in applications such as DC-DC converters, telecoms, networking equipment, automotive, battery-backed systems, computers, and consumer electronics.The SMAJ160A has a RoHS (Restriction of Hazardous Substances) directive compliant lead-free termination finish. The device is available in an ultra-small SMD package, which offers excellent protection against high-energy transient pulses with a breakdown voltage of 259V, 178V and 160V. This TVS diode also features low leakage current, fast response time and excellent junction-to-case thermal conduction.
