The 1.5KE39ARL4G: The DO-201AD axial package suits through-hole board layouts where a robust, hand-solderable body is preferred over surface-mount alternatives.
The single unidirectional channel protects one rail per device; for bidirectional or multi-line protection, multiple units or a different TVS topology is needed.
This rating determines the surge energy the diode can absorb before failure.
