1500W peak pulse in a DO-201 axial body
The 1.5KE170AH: Its 145V reverse standoff voltage and 162V minimum breakdown mean it starts clamping just above a 145V rail, holding transients to 234V maximum at the 6.7A peak pulse current (10/1000µs waveform).
AEC-Q101 grade for under-hood and chassis duty
The 1500W pulse rating is tested into a 10/1000µs waveform per the TVS test standard; for shorter pulses (like 8/20µs) the peak power capability is higher, but the 234V clamp voltage stays the same — the load's voltage tolerance must hold above that ceiling.
Active production — no end-of-life risk on this BOM line
No single-source exposure — the DO-201 package and 1.5KE series are widely second-sourced across the TVS industry.
