Diodo TVS SMF18A SOD-123FL

SMF18A belongs to Slkor SMFxxA series unidirectional transient voltage suppressor diodes, encapsulated in JEDEC standard low-profile SOD-123FL surface-mount plastic package. This single-channel unidirectional TVS is designed to absorb transient surge energy and protect voltage-sensitive circuits from ESD, lightning surge and pulse interference. It features high peak pulse power capacity, low incremental surge resistance and superior clamping performance. With compact thin-body outline, wide temperature adaptability and stable power derating characteristics, it is widely applicable to various surface-mount consumer, industrial and communication electronic equipment with limited PCB space.
