The 1.5SMC600A is a high-voltage transient voltage suppressor rated at 1500W peak pulse power (10/1000µs), engineered to protect 400–600V DC power rails from lightning surges, inductive switching spikes, and industrial overvoltage events. Housed in a DO-214AB (SMC) package, it provides excellent clamping capability, fast response time, and high reliability for industrial power supplies, automation systems, and energy infrastructure.
