That clamping ceiling at 92V is the figure that protects downstream circuitry — a 12V rail sees roughly a 7.5× ratio from standoff to clamp, which is typical for this series. ## Junction temperature range and rework profile Delivered on tape and reel (TR), which suits high-volume pick-and-place lines. For rework, a hot-air gun at 350-380°C with flux preform will lift the body without disturbing adjacent components on a populated board. ## Where the 1.5SMC family fits General-purpose TVS diodes like the 1.5SMC68CA protect signal lines, low-power rails, and discrete FET gates from ESD and surge transients. This part is classified as not suitable for power-line protection (flags Power Line Protection: No) — for AC line duty the 1.5SMC series is not the right fit; look to the P6SMB or SMBJ families instead.","metaTitle":"1.5SMC68CA R7G TVS Diode, 1500W, 58.1V","metaDescription":"Taiwan Semiconductor 1.5SMC68CA R7G, 1500W peak pulse TVS diode in DO-214AB SMC. 58.1V standoff, 64.6V breakdown, 92V clamping.

The voltage rating is set by the base number 1.5SMC68, where 68 denotes the approximate standoff voltage in volts. Choosing between CA (bidirectional) and A (unidirectional) variants depends on whether the protected line is symmetric (AC, bidirectional signal) or DC-biased."},{"question":"What is the 1.5SMC68CA R7G's listed type on the Circuit Protection line?","answer":"The device is classified as a Zener type, which in the TVS context means it operates as a Zener breakdown clamp — the bidirectional CA variant uses two Zener junctions back-to-back to clamp both polarities."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CA-R7G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CA-R7G when reusing this data.
