Product details

Active production, automotive-qualified transient suppressor

The 1.5KE18AH is an active-production TVS Zener diode from Taiwan Semiconductor Corporation, part of the 1.5KE series.

AEC-Q101 qualification and temperature envelope

Qualified to AEC-Q101, the 1.5KE18AH meets the automotive-grade stress tests for temperature cycling, high-temperature reverse bias, and ESD robustness. The junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles. The DO-201AA (DO-27) axial-lead package is through-hole mounted, suited for high-reliability power supply and battery-line clamping where surface-mount packages may be thermally marginal at 1500W pulse energy.

Sourcing and compliance posture

Availability, current pricing, and lot traceability are confirmed at RFQ time. The part carries the standard Taiwan Semiconductor compliance documentation for RoHS and REACH.
