1500W Zener TVS for automotive and industrial surge protection
The 1.5KE180AH is a 1500W peak-pulse Zener TVS diode from Taiwan Semiconductor's 1.5KE series, rated for unidirectional transient suppression in automotive and industrial power rails.
Protection window: standoff, breakdown, and clamping
Reverse standoff voltage is 154V, meaning the diode draws negligible leakage below this rail voltage. The 1500W peak-pulse rating at 10/1000µs defines the surge energy it can absorb in a single event — typical for load-dump or inductive kickback clamping in 12V and 24V automotive systems.
Package and board integration
Housed in a DO-201AA (DO-27) axial leaded package, the through-hole mounting simplifies manual replacement and rework compared to surface-mount TVS diodes on the same power rail. The axial leads suit point-to-point wiring or PCB through-hole layouts where the diode is often placed directly across the input connector or relay coil.
The part is sourced to order against BOM quantities through independent distribution. No official successor or second-source cross-reference is listed; the 1.5KE180AH is the current production order code for this rating.
