P4SMA440A

The P4SMA440A is a surface-mount transient voltage suppressor rated at 400W peak pulse power (10/1000µs), optimized for high-voltage DC power rails. It provides fast and reliable clamping against lightning-induced surges and switching transients, making it suitable for industrial power supplies, HV control circuits, and DC bus protection.
