The 1.5KE20CA B0G: With a 17.1 V reverse standoff voltage and a 19 V minimum breakdown, this part clamps transients at 27.7 V maximum, protecting a 12 V or 15 V DC bus from load-dump and lightning-induced surges up to 56 A peak.
The DO-201AA / DO-27 axial-lead package (through-hole) is a standard footprint for 1500 W TVS diodes — the leads handle the thermal pulse during clamping without lifting the pad.
With a 17.1 V reverse standoff and 19 V minimum breakdown, it is sized for 12 V or 15 V DC buses, clamping transients at 27.7 V maximum.
