1500 W bidirectional TVS for 20.5 V rails
The 1.5KE24CA/54: It clamps transients at 33.2 V maximum while conducting 45.2 A peak pulse current, and its 20.5 V reverse standoff voltage means it stays transparent on a nominal 20 V DC or AC rail until a surge forces it into breakdown. 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.
