The SA190A is a unidirectional transient voltage suppressor diode rated at 500W peak pulse power (10/1000µs), engineered to protect 190V DC circuits against lightning-induced surges, inductive load switching, and transient overvoltage events. Housed in a DO-15 axial package, it offers fast response time, low leakage, and stable clamping performance for industrial power supplies, control systems, communication equipment, and high-voltage signal interfaces.
