1.5 kW bidirectional TransZorb — last-buy status
The 1.5KE12CA-E3/51: The manufacturer has placed this part in last-buy status.
Clamping voltage and breakdown margins
This 5.3 V window between standoff and clamp means a 12 V supply rail sees only a brief overvoltage before the device conducts, protecting downstream silicon rated for 20 V or less. The single bidirectional channel handles both positive and negative transients — no polarity concern during installation, which simplifies kitting for general-purpose board protection. The DO-201AA axial package (DO-27 equivalent) is through-hole mounted, suitable for point-of-entry protection on power input lines where a leaded form factor provides mechanical strain relief.
