The single bidirectional channel handles positive and negative polarity transients in one device, simplifying layout on bipolar supplies or AC-coupled lines. The breakdown voltage range starts at 22.8 V minimum, so the device triggers before the protected circuit's absolute maximum rating is reached. ## Obsolete — sourced through independent channels Vishay lists the 1.5KE24CA/54 as obsolete. Sourcing is handled through independent distribution and surplus channels; each lot is verified for authenticity and traceability before quoting. Availability and pricing are confirmed at RFQ against the BOM quantity. ## Through-hole DO-201AA package for leaded assembly The leaded body handles the thermal pulse energy of a 1500 W surge without requiring a heatsink — the copper leads and junction-to-lead thermal path absorb the transient. The Tape & Reel (TR) packaging option suits automated insertion for high-volume builds.","metaTitle":"Vishay 1.5KE24CA/54 TransZorb TVS, 1500W, 20.5V Standoff","metaDescription":"Obsolete Vishay 1.5KE24CA/54 bidirectional Zener TVS diode, 1500W peak pulse, 20.5V standoff, 33.2V clamp.
