Automotive-grade transient suppressor with AEC-Q101 pedigree
The 1.5KE150AHE3_A/C: Its 128 V reverse standoff voltage and 207 V clamping point protect 120 V nominal rails from load-dump and inductive kickback transients.
Thermal and surge ratings for under-hood duty
No power line protection feature is implemented — this is a dedicated transient suppressor for signal or low-power supply rails, not a mains-side protector.
Package and board integration
Supplied in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE150AHE3_A/C mounts with standard 0.040-inch diameter holes and is compatible with wave-solder assembly. The axial body suits point-to-point wiring or PCB layouts where the lead bend radius is controlled to avoid stress on the glass passivation. Tape and reel packaging supports automated insertion for medium-to-high volume production runs.
The base product number 1.5KE150 identifies the family; the A suffix denotes a 5% tolerance on breakdown voltage, and the HE3 coding indicates AEC-Q101 qualification with automotive-level process controls and lot traceability.
