1500W bidirectional transient suppressor — last-buy window
The 1.5KE8.2CA-E3/51: The manufacturer has placed this part in Last Buy status, meaning the final production lots are being allocated now. Any BOM still using this order code needs a last-time-buy quantity committed or a replacement qualified before the window closes.
Through-hole DO-201AA — board-fit and temperature range
Housed in a DO-201AA (DO-27) axial-lead package, this diode handles the 1500 W pulse without the thermal spreading limits of a surface-mount package. The bidirectional channel suppresses both positive and negative transients from a single device, reducing component count on the rail. No power-line protection feature is claimed — this is a signal or low-power rail protector, not a mains-side suppressor.
Sourcing this last-buy part
With the Last Buy designation, Vishay will stop manufacturing this order code after the final production run. Sourcing is through independent distribution channels that hold remaining factory inventory or surplus stock. A quote against your BOM quantity confirms availability and pricing at the time of request. For a drop-in replacement, the same TransZorb family offers other bidirectional 1500 W devices with different standoff voltages — the 7.02 V standoff here is specific to the 8.2 V nominal rating.
