It clamps transients at a minimum breakdown voltage of 14.3V and handles 1500W peak pulse power. The DO-201AD axial package suits through-hole board layouts where a replaceable, high-surge component is preferred over surface-mount. The 12.8V reverse standoff voltage means it starts conducting only above normal 12V rail levels, making it a fit for 12V system transient protection — automotive, industrial control, or telecom line-side clamping. ## Obsolete — sourcing reality for the 1N6275A onsemi lists the 1N6275A as Obsolete. No official successor is cited. For a BOM line that needs this exact order code, the only channel is the independent market — we source and quote to order against your quantity. The base product number 1N6275 shares the same die and package; the 'A' suffix typically indicates a tighter tolerance on breakdown voltage. If your application can tolerate the standard tolerance, the non-A variant may be a drop-in alternative — confirm the clamping voltage spec against your design margin. ## Key ratings and what they mean for your BOM The 1500W peak pulse power rating is specified at 10/1000 µs waveform — the standard TVS test condition. For shorter pulses (e.g. 8/20 µs), the diode can absorb significantly more peak current; for longer transients, derate accordingly. This rating sets the upper bound on the surge energy the diode can clamp before failure. Operating temperature range -65°C to 175°C covers military and industrial extremes. The junction temperature limit of 175°C means the device can sit in a hot enclosure or near a heatsink without derating the pulse capability, as long as the average power dissipation stays within the package limits.","metaTitle":"1N6275A onsemi Zener TVS – 14.3V Breakdown, 1500W, DO-201AD","metaDescription":"onsemi 1N6275A Mosorb™ Zener TVS, 12.8V standoff, 14.3V min breakdown, 1500W peak pulse, DO-201AD axial.

Both share the same base product number, package, and 1500W rating. If your design can accept the looser tolerance of the non-A variant, it may serve as a functional replacement — verify the clamping voltage spec against your protection threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6275A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6275A when reusing this data.
