With a reverse standoff voltage of 9.4V and a maximum clamping voltage of 15.6V at the rated peak pulse current, it is designed to protect 9V or 10V DC power rails from transient overvoltage events such as inductive load switching or lightning-induced surges. ## Obsolete — sourcing reality and replacement planning onsemi has marked the 1N6272A as Obsolete. For a BOM line that requires this exact order code, the supply path is limited to verified distributor inventory, broker stock, or surplus lots — no last-time-buy window remains open. A design-in replacement should be identified and qualified before the existing stock is exhausted. ## Package and temperature range for through-hole board fit The 1N6272A is supplied in a DO-201AD axial-lead through-hole package, with a bulk (tube or loose) packaging option. The operating junction temperature range spans -65°C to +175°C, making it suitable for industrial or automotive environments that see wide thermal swings — though the obsolete status limits its use to legacy designs or repair stock. ## Breakdown voltage and unidirectional configuration The minimum breakdown voltage at 1 mA is 10.5V. The device has a single unidirectional channel and does not include power line protection features — it is intended for signal or low-voltage DC rail clamping, not for AC mains or high-voltage bus protection.","metaTitle":"1N6272A onsemi Mosorb™ Zener TVS 1500W DO-201AD Obsolete","metaDescription":"1N6272A onsemi Mosorb™ Zener TVS diode, 1500W peak pulse power, 9.4V standoff, 15.6V clamp.

This is the peak power it can dissipate during a transient event; steady-state power dissipation is much lower and depends on the heatsinking and duty cycle."},{"question":"What is the difference between 1N6272A and 1N6272?","answer":"The suffix 'A' typically indicates a tighter tolerance on the breakdown voltage in the 1N6272 series. The 1N6272A has a minimum breakdown of 10.5V, while the non-A version has a wider range. The clamping and standoff voltages are the same for both variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6272A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6272A when reusing this data.
