Product details

Automotive-grade transient suppression for 171 V rails

The 1.5KE200CAHA0G: The DO-201AA (DO-27) axial-lead package supports through-hole mounting on boards where a low-inductance path to the protected rail matters — the lead frame carries the pulse current without exceeding the junction temperature limit of -55°C to 175°C.

Active production and sourcing posture

Sourced through independent distribution channels; pricing and lead time are confirmed at RFQ against the buyer's quantity and delivery window.
