1.5KE400CA, 1500W Bidirectional TVS Diode, DO-201

The 1.5KE400CA is a transient voltage suppression diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. With a standoff voltage of 342V, it clamps voltage surges up to 548V, ensuring the safety of downstream components. Its bidirectional nature makes it suitable for AC circuits and applications where both positive and negative transients are a concern. The DO-201 package facilitates through-hole mounting, providing mechanical stability and ease of integration into various designs.​
