Breakdown and clamping window
The 1.5KE62AHE3_B/C: Minimum breakdown voltage is 58.9 V, with the reverse standoff set at 53 V — the device remains non-conductive below 53 V and starts clamping above the breakdown threshold, limiting the transient to 85 V at the rated 18 A peak pulse current. The 1500 W peak pulse rating at 10/1000 µs means the diode absorbs a 1 ms exponential surge; for shorter transients (e.g. 8/20 µs) the peak power capability is higher, but the 1500 W figure is the baseline for comparing against other DO-201AA TVS parts.
Supplied in the DO-201AA (DO-27) axial-lead package, through-hole mounted — the 1.5KE supplier device package code matches the lead form and body dimensions for this power class. Tape-and-reel packaging supports automated insertion for high-volume board assembly; the axial leads require lead-forming for through-hole placement.
