caption_attribution_description: English: 1.5KE en:Transil diodes (1.5kW transient voltage suppressor, or TVS, diodes). The top device is a 1.5KE20A. Color band denotes cathode on unidirectional devices, and is not present on bidirectional ones.
context_page_description: A transient-voltage-suppression diode, also transil or thyrector, is an electronic component used to protect electronics from voltage spikes induced on connected wires.
