Product details

Clamping voltage and pulse power for 24 V systems

The 1.5KE68CAHA0G: With a breakdown voltage range starting at 64.6 V and a clamping ceiling of 92 V at 17 A, this part protects 48 V and 58 V nominal rails in automotive load-dump and ISO 7637-2 transient environments. The bidirectional channel suppresses both positive and negative transients from a single device, which simplifies board layout in AC-coupled or floating-ground circuits.

Through-hole DO-201 package for high-reliability mounting

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE68CAHA0G mounts through-hole — the leaded format provides a lower thermal resistance path to the board than surface-mount equivalents, which matters when the junction temperature reaches 175 °C during repetitive surge events.

Active production and sourcing posture

It is sourced through authorized and independent distribution channels; pricing and lead time are confirmed at RFQ against the BOM quantity.
