What the key ratings mean for your BOM
The 1.5KE130AHE3_A/C: The 111V reverse standoff voltage means the diode conducts negligible leakage below this rail voltage — it protects 100V to 110V DC buses or 85V AC rectified lines without interfering with normal operation. 179V clamping at 8.4A means the protected circuit sees no more than 179V across the TVS during a 1500W surge event — this keeps downstream MOSFETs and ICs within their 200V breakdown margins.
Package and board-fit for replacement and assembly
The DO-201AA (DO-27) axial through-hole package is a standard 5mm body diameter with 0.96mm lead diameter — compatible with existing PCB layouts for 1.5KE-series TVS diodes. The through-hole form factor allows hand-replacement in rework without hot-air equipment. Supplied in Tape & Reel format for automated insertion — the reel quantity supports high-volume pick-and-place through axial component feeders.
