What the 1500W peak pulse rating means for your board
The 1.5KE36A_R2_00001: With a 30.8V reverse standoff voltage, it stays transparent on a 24V or 28V rail and clamps at 49.9V max, shunting up to 30A of surge current away from downstream circuitry. The DO-201AE axial-lead package handles the thermal pulse without cracking the junction, provided the lead length is kept short to minimise inductance.
Lifecycle reality — obsolete, not dead
Panjit lists this part as Obsolete. For existing BOM lines, the supply channel is independent surplus and excess inventory — each lot is verified for authenticity and traceability before quoting.
Temperature envelope and mounting
The junction operates from -65°C to 175°C, covering military and industrial extremes. Through-hole mounting in the DO-201AE axial package means the leads are soldered into plated through-holes — the body stands off the board, so conformal coating flows underneath without bridging the anode and cathode bands. The cathode band is marked on the body; orientation matters for unidirectional clamping.
