The 30KPA90CA with 146.4V 100.5V 90V P600 TVS ROHS manufactured by Yageo is an unidirectional transient voltage suppressor (TVS) diode. It is designed to protect against the effects of electrical overstress, such as voltage spikes, by providing a clamping action to limit voltage transients. It has a peak power dissipation of 600W for 10/1000 µs and a maximum clamping voltage of 146.4V at 100.5V for a 90V transient. The diode is RoHS (Restriction of Hazardous Substances) compliant and is certified for use in a wide range of applications.
