The SMAJ250A with SMA TVS ROHS manufactured by FOSAN is a uni-directional, surface mount Transient Voltage Suppressor (TVS) diode. This device is designed to protect electronic equipment from voltage transients induced by inductive switch loads, cable discharge, and lightning. It is widely used in telecommunications and networking equipment, consumer electronics, gaming and video displays, instrumentation, and automotive systems. This particular device is housed in an SMA package size, meets the requirements of the Restriction of Hazardous Substances (RoHS) Directive, and provides an ultimate peak pulse power dissipation rating of 250W. The operating voltage range is 5-170V. It is compatible with standard surface mount technology processes and features a low typical clamping voltage and fast response time.
