1500 W peak pulse in an automotive-grade axial package
The 1.5KE16AH: Its 13.6 V reverse standoff voltage and 22.5 V clamping maximum at 70 A peak pulse current make it a fit for 12 V automotive rail protection — the standoff sits above the nominal bus voltage while the clamp keeps transients off downstream electronics.
Voltage breakdown and clamping margins
Minimum breakdown voltage is 15.2 V, giving a guard band above the 13.6 V standoff — the diode stays off during normal operation and only conducts when a transient pushes the rail past the breakdown threshold. Maximum clamping voltage of 22.5 V at the rated 70 A pulse current defines the worst-case voltage the protected circuit sees; a 12 V nominal rail with a 24 V abs-max input can survive this clamp level with margin.
DO-201 axial package and board integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE16AH mounts through-hole — the body and lead diameter are standard for 1500 W TVS diodes, so the PCB footprint and hole size match existing layouts for this power class. The axial format suits point-to-point wiring or through-hole PCB assembly where the diode is placed close to the connector or power entry point to minimise loop inductance between the TVS and the protected circuit.
