Product details

Clamping and breakdown parametrics

The 1.5KE20CAHE3_A/C: The 17.1 V standoff gives margin below a typical 24 V nominal bus, so the diode stays off during normal operation and only conducts when a transient exceeds the breakdown threshold. Operating junction temperature range spans -55°C to 175°C, covering the full automotive temperature envelope including hot-soak under-hood conditions.

Supplied in a DO-201AA (DO-27) axial-lead package for through-hole mounting. The 1.5KE body size handles the 1500 W pulse without exceeding the thermal limit of the lead frame.
