The through-hole mounting allows the axial leads to be soldered into plated through-holes on a standard PCB or wired into a terminal block — the lead bend radius should be at least twice the lead diameter to avoid cracking the glass passivation layer on the die.","metaTitle":"1.5KE180CA-E3/54 Vishay TVS, 1500W, 154V Standoff, DO-201","metaDescription":"Vishay 1.5KE180CA-E3/54 TransZorb® bidirectional TVS diode, 1500W peak pulse, 154V standoff, 246V clamp.

Above 171 V (the minimum breakdown), it begins to avalanche and clamp the transient. The 246 V clamping voltage is the maximum voltage the protected circuitry will see during a 6.1 A peak pulse event."},{"question":"Is this part suitable for power line protection?","answer":"No, the 1.5KE180CA-/54 is not rated for power line protection. It is intended for signal and data line transient suppression where the energy is limited to single-pulse events. For AC mains protection, a higher-energy MOV or a TVS rated for continuous AC operation would be required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE180CA-E3-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE180CA-E3-54 when reusing this data.
