The SMF11A is a unidirectional transient voltage suppression diode engineered to protect 11V DC power systems from ESD events, switching transients, and lightning-induced surges. Rated at 200W peak pulse power (10/1000µs), it offers fast response time, low clamping voltage, and stable breakdown performance. The compact SOD-123FL package makes it ideal for industrial control, automotive electronics, and DC power interface protection.
