Product details

Package and board integration

The 1.5KE47CHE3/54: Housed in a DO-201AA (DO-27) axial-lead package, the diode is through-hole mounted. The 1.5KE body size is standard for 1500W TVS diodes — the lead spacing and body diameter match common PCB footprints for this power class. The bidirectional configuration uses a single device for symmetrical clamping on AC or bipolar signal lines, eliminating the need for two back-to-back unidirectional diodes.

For existing BOM lines, the 1.5KE47CHE3/54 remains a drop-in fit where the DO-201AA footprint and 1500W peak pulse rating are specified.
