1500W peak pulse — what the rating means for your rail
The 1.5KE36CA-E3/54: Rated 1500W peak pulse power for a 10/1000µs exponential waveform, the 1.5KE36CA-/54 clamps a 30.1A surge to 49.9V maximum. The 30.8V reverse standoff voltage means it stays transparent on a 24V or 28V rail, only conducting when the transient exceeds the 34.2V minimum breakdown threshold. Bidirectional single-channel configuration protects both positive and negative transients on the same line — useful for AC-coupled signals or floating supplies where polarity is not fixed.
Package and board-fit — DO-201AA axial through-hole
Supplied in the DO-201AA / DO-27 axial leaded package, the 1.5KE36CA-/54 mounts through-hole on the PCB. The 1.5KE body code is marked on the device body for visual identification during inspection or rework.
Sourcing and compliance — what to expect at RFQ
Vishay General Semiconductor provides RoHS and REACH compliance documentation with the shipment. The part is not rated for power line protection — it is intended for secondary-side transient suppression on signal or low-voltage DC rails.
