The 1.5SMB100A is a high-reliability surface-mount TVS diode rated at 1500W peak pulse power (10/1000µs). It is designed to protect 100V DC power lines from lightning-induced surges, inductive switching transients, and overvoltage spikes. The DO-214AA (SMB) package provides compact PCB integration, fast response time, and excellent clamping performance for industrial power supplies, communication systems, and control electronics.
