Product details

Transient protection envelope and what it means for your rail

The 1.5KE150CA-E3/73: Its 143 V minimum breakdown voltage means it starts conducting just above the rail's normal operating ceiling, and the 207 V maximum clamping voltage at 7.2 A peak pulse current (10/1000 µs waveform) defines the voltage the downstream equipment must survive.

Package and board integration for the DO-201AA axial footprint

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE150CA-/73 mounts through-hole on the PCB. The axial leads carry the full 7.2 A peak current without resistive heating at the solder joint — the lead cross-section and the copper pad area under the body set the thermal impedance for the pulse.
