The listed package unit count is Strip — confirm the reel or tape-and-reel orientation and cathode marking standard with your assembly house if you are loading on a high-speed SMT line, since DO-214AB variants share the same footprint and mixed loading is a real risk on multi-SKU panels. ## Operating temperature grade Rated junction temperature of -50°C to 150°C (TJ) covers the industrial operating band — the lower bound handles cold-start and outdoor equipment, and the upper bound gives margin against self-heating during a clamping event before the protection clears. Power-line protection is listed as No — confirm this device is selected for signal-line or component-level clamping rather than main power bus protection.","metaTitle":"1.5SMCJ20A TVS Diode, 1500W, 20V Standoff, DO-214AB","metaDescription":"Diotec 1.5SMCJ20A unidirectional TVS Zener, 1500W peak pulse, 20V standoff, 32.4V clamping, DO-214AB SMC.

The 1.5SMCJ20A is a Zener-based unidirectional TVS (transient voltage suppressor), not a Schottky barrier diode — the breakdown voltage window (Min 22.2V) and the 10/1000µs peak pulse rating are characteristic of Zener TVS behaviour under transient suppression, not Schottky forward-conduction characteristics."},{"question":"What package does the 1.5SMCJ20A use — and is it easy to handle on site?","answer":"DO-214AB (SMC) surface-mount package — the two-terminal polarity-aware body is straightforward to identify by the cathode band, but rework in the field requires hot-air reflow or a热气 reflow station rather than a simple iron swap, and anti-static handling applies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ20A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ20A when reusing this data.
