1.5 kW clamping in a DO-201AA axial package
The 1.5KE15CA-E3/51: The 1.5KE15CA-/51 is a 1500 W peak pulse power (1.5 kW) bidirectional TVS diode from Vishay's TransZorb series, clamping transients at 21.2 V maximum when hit with a 70.8 A 10/1000 µs pulse. The 12.8 V reverse standoff voltage means the protected rail sits below the clamping threshold during normal operation, and the 14.3 V minimum breakdown ensures the device triggers before the downstream silicon sees damage.
Last Buy — sourcing a line that is closing
Vishay has flagged this part as Last Buy, meaning the manufacturer is no longer accepting new orders beyond a defined window. For a BOM that already carries this order code, the procurement decision is time-constrained: secure the last-time-buy quantity or plan the replacement now.
The through-hole DO-201AA axial package (also listed as DO-27) suits point-to-point wiring or PCB mounting with a simple through-hole footprint — no special pad geometry needed beyond the lead spacing.
