The 1.5KE10CA-E3/51: Vishay has placed the 1.5KE10CA-/51 on Last Buy — this is the final production run. Orders placed now draw from the remaining factory allocation; once the window closes the part is available only through independent surplus channels.
Clamping performance and application fit
The 14.5 V clamp means a 12 V rail sees the transient clipped well below the typical 20 V abs-max of downstream regulators. The bidirectional construction protects lines that swing both positive and negative relative to ground — common on AC-coupled data lines or ungrounded battery terminals.
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE10CA-/51 is a through-hole part suited for point-to-point wiring on terminal strips or PCB mounting with lead forming. The operating junction temperature range is -55°C to +175°C, covering military and industrial thermal profiles.
