The reverse standoff of 220 V defines the working voltage the diode must hold off during normal operation; anything above that triggers the breakdown window starting at 242 V minimum. The DO-214AB (SMC) package is the standard surface-mount footprint for 1.5 kW-class TVS diodes — the cathode bar on the package marks the direction of protection. Because it is not classified as a power-line protection device, the 1.5SMCJ220A_R1_00001 is suited for secondary protection behind a primary fuse or an upstream bulk TVS — it absorbs residual clamping work that gets past the first stage, not the initial event. The tape-and-reel and cut-tape packaging options cover both high-volume SMT assembly and low-quantity prototyping runs. ## Sourcing posture and lifecycle No pin-compatible successor or second-source cross-reference appears in the ledger for this specific order code, so the BOM line should be validated against the existing approved design before committing to a new source.","metaTitle":"Panjit 1.5SMCJ220A_R1_00001 TVS Diode, 220V, 1.5kW","metaDescription":"Panjit 1.5SMCJ220A_R1_00001 unidirectional Zener TVS diode, 220V standoff, 356V clamping, 1.5kW peak pulse, DO-214AB SMC.

The breakdown voltage minimum of 242 V is where the diode begins conducting in the reverse direction — the onset of the protection action. The clamping voltage of 356 V at 4.2 A peak pulse is what the downstream circuit is exposed to during a surge event; the diode clamps the spike at or below that level, protecting the load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ220A_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ220A_R1_00001 when reusing this data.
