Product details

1.5kW clamp for 94V rails

The 1.5KE110A A0G: Its 152V maximum clamping voltage at the rated 10.3A peak pulse current (10/1000µs waveform) means a 94V supply line seeing a 1.5kW surge gets held below 152V — well within the typical 200V abs-max of downstream DC-DC converters and linear regulators in industrial power stages. The 105V minimum breakdown voltage ensures the diode starts conducting before the rail reaches a damaging level, while the 94V reverse standoff guarantees no leakage at the nominal operating voltage.

Through-hole axial for board-level transient suppression

Packaged in the DO-201AA (DO-27) axial leaded form, the 1.5KE110A A0G mounts through-hole — the large body and thick leads handle the thermal energy of a 1.5kW pulse without lifting pads or cracking solder joints. The single unidirectional channel means one diode per rail; for bidirectional protection on AC-coupled lines, two devices back-to-back or a dedicated bidirectional TVS is needed.
