1500 W peak pulse in a DO-201AE axial
The 1.5KE8.2A-TP: It clamps transients at 12.1 V maximum when the surge current hits the rated level, protecting downstream circuitry on a 7.02 V nominal rail. Housed in the DO-201AE axial-lead package, it mounts through-hole and suits general-purpose transient suppression on power inputs, relay coils, and low-voltage DC buses where board space is not the constraint.
Voltage thresholds and clamping behaviour
The reverse standoff voltage is 7.02 V typical — the rail voltage below which the diode stays off and leakage is negligible. Breakdown occurs at a minimum of 7.79 V, and the clamp voltage is held to 12.1 V maximum at the peak pulse current Ipp.
The junction operates from -55 °C to 175 °C, covering the full industrial and automotive ambient range with headroom for self-heating during repetitive surge events. No power line protection function is integrated — this is a dedicated transient suppressor, not a filter.
