The SMF43A is a unidirectional transient voltage suppression diode engineered to protect 43V DC power systems from lightning-induced surges and switching transients. Rated at 200W peak pulse power with a 10/1000µs waveform, it provides fast response, low clamping voltage, and stable performance. The compact SOD-123FL package makes it ideal for industrial control, communication equipment, and power interface protection.
