The 29.83V minimum breakdown voltage ensures the TVS does not conduct during normal 24V operation, yet triggers well before the downstream circuitry sees damaging overvoltage. ## Active Lifecycle and Sourcing The SQ-MELF (B, MELF-style) surface-mount package is widely available through distribution.","metaTitle":"1N6118US Zener TVS, 500W, Bidirectional, SQ-MELF, Active","metaDescription":"1N6118US Zener TVS diode, 500W peak pulse, 25.1V standoff, bidirectional, SQ-MELF surface mount.

The 25.1V reverse standoff voltage sits comfortably above a nominal 24V rail, and the 29.83V minimum breakdown ensures no leakage during normal operation. The 500W peak pulse rating handles typical industrial surge events per IEC 61000-4-5."},{"question":"What is the closest pin-compatible alternative to 1N6118US?","answer":"Within the same Microchip 1N6118 family, the 1N6118 (through-hole DO-13 variant) shares identical electrical ratings but differs in package. For a surface-mount alternative, devices from the 1N6118US series with different voltage grades (e.g., 1N6118US for 25.1V standoff) are direct pin-compatible in the same SQ-MELF footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6118US","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6118US when reusing this data.
