Its 8.55V reverse standoff voltage makes it a fit for protecting 5V or 8V DC buses from transients up to 14.5V clamping. The DO-201AD axial package is a through-hole form factor common in industrial power supplies and telecom line cards where board-level surge protection is needed. ## Obsolete – plan for replacement or last-time buy onsemi has marked the 1N6271AG as Obsolete. No official successor is listed in the available records. For new designs, consider a current-production TVS with similar 1500W rating and 8.55V standoff in a comparable package. For existing BOMs, remaining inventory is the only source – we can source and quote to order against your quantity. ## Through-hole assembly and temperature range The axial package requires a through-hole PCB footprint with adequate copper area for heat sinking during pulse events. Operating temperature spans -65°C to 175°C junction, covering industrial and some automotive under-hood environments.","metaTitle":"1N6271AG onsemi Mosorb™ Zener TVS – 1500W, DO-201AD","metaDescription":"1N6271AG onsemi Mosorb™ Zener TVS diode, 1500W peak pulse power, 8.55V reverse standoff, DO-201AD axial.
