Automotive-grade transient suppression for 171 V rails
The 1.5KE200AH: Its 171 V reverse standoff voltage protects 170–180 V DC buses common in automotive traction inverters and on-board chargers. Breakdown occurs at 190 V minimum, clamping transients to 274 V maximum at 5.7 A peak pulse current. The junction operates from -55°C to 175°C, covering the full under-hood temperature profile.
AEC-Q101 qualification and active lifecycle
Qualified to AEC-Q101, the automotive discrete semiconductor stress test standard — this covers temperature cycling, high-temperature reverse bias, and ESD robustness required for PPAP submissions. The DO-201 (DO-27) axial-lead package suits through-hole assembly in high-reliability power stages where surface-mount TVS may not handle the surge energy without board delamination.
