Active production, standard TVS diode for general-purpose clamping
The 1.5KE12CA: It clamps transients at 16.7 V max while conducting 91 A peak pulse current, making it a straightforward fit for protecting 12 V DC rails in industrial and telecom gear. The 10.2 V reverse standoff means the diode stays out of the circuit below that voltage, so a 12 V supply rail sits safely under the clamping threshold during normal operation. The 11.4 V minimum breakdown voltage gives a tight guard band — useful when the rail has tight regulation and you need the TVS to trigger before the downstream silicon sees damage.
DO-201 axial package — field-swappable with basic tools
The DO-201AA (DO-27) axial-lead package is a through-hole part that solders into a board or can be crimped into a terminal block. No hot-air station needed — a standard iron or soldering gun handles the swap, and the body is large enough to read the part marking without magnification. The wide thermal margin means the diode can absorb repetitive pulses without derating the ambient temperature, as long as the average power stays within the package's dissipation limits.
Sourcing and compliance
The part carries the base product number 1.5KE and is listed for general-purpose applications.
