The 1.5KE15CA/B: The bidirectional construction (single channel) means it protects circuits that see both positive and negative transients relative to ground — common on signal lines or DC power inputs where polarity reversal is a risk.
Housed in a DO-201AA (DO-27) axial-lead package, the through-hole mount suits point-to-point wiring or PCB layouts where a leaded part is preferred for mechanical strength or rework ease.
At 12.8 V reverse standoff, the diode remains non-conductive. On a transient, breakdown starts at 14.3 V minimum, and the voltage is clamped to a maximum of 21.2 V while conducting 71.7 A peak pulse current (10/1000 µs waveform).
