1500 W bidirectional TVS — last-buy sourcing reality
The 1.5KE160CA-E3/51: It clamps at 219 V max and has a reverse standoff voltage of 136 V, so it protects 120–130 V DC rails from transients without conducting during normal operation. The breakdown voltage range starts at 152 V minimum, meaning the diode begins to avalanche before the clamping voltage is reached.
Last-buy status — what it means for your BOM
Vishay has marked the 1.5KE160CA-/51 as Last Buy. This is not an active-production part for new designs — it is in the end-of-life wind-down. The TransZorb series has a broad portfolio, and a pin-compatible bidirectional 1500 W TVS with the same standoff voltage is the natural cross-reference candidate. For existing BOM lines already qualified to this order code, the Last Buy window is the time to secure final-lot inventory or to validate a drop-in replacement.
