What the 1500W peak pulse rating means for your protection design
The 1.5KE36C-E3/54: The 52V maximum clamping voltage at 28.8A peak pulse current (10/1000µs waveform) defines the voltage the downstream circuitry must survive — any device rated below 52V sees the full clamping stress.
Bidirectional protection for AC lines and bipolar rails
A single bidirectional channel covers both polarities — useful for AC-coupled signal lines, data pairs, or dual-supply rails where the transient can swing positive or negative. The 29.1V reverse standoff means the diode draws negligible leakage at normal operating voltage up to that level. The DO-201AA axial-lead package (also known as DO-27) is a through-hole format rated for the full 1.5kW peak pulse without derating at 25°C ambient.
Obsolete — sourcing through independent channels
Vishay has marked the 1.5KE36C-/54 as obsolete.
