Automotive-grade transient suppressor for 24V rails
The 1.5KE27AHE3_A/D: With a 23.1V reverse standoff voltage and 25.7V minimum breakdown, it protects 24V nominal power rails in engine bays, body controllers, and infotainment systems against load-dump and inductive-load transients.
Clamping performance and pulse handling
This part clamps at 37.5V maximum at the 40A peak pulse current (10/1000µs waveform), limiting the voltage seen by downstream electronics during a surge event. The -55°C to +175°C operating junction temperature range covers under-hood thermal extremes, and the DO-201AA axial-lead package (DO-27 variant) allows through-hole mounting for high-reliability connections in vibration-prone assemblies.
