Surge protection for 130V automotive rails
The 1.5KE160CH is a bidirectional Zener-type TVS diode from the 1.5KE series, designed to clamp transients on DC power rails or AC signal lines up to 130V nominal. The bidirectional configuration means a single device protects both polarities — useful for AC-coupled lines or where the signal swings through zero.
AEC-Q101 qualification and temperature range
The qualification covers the reliability stress tests (HTRB, H3TRB, temperature cycling) that commercial-grade parts skip. The DO-201 (DO-27) axial-lead through-hole package mates with standard 0.040-inch diameter plated-through holes on power supply boards. The lead form is compatible with wave-solder processes; no special reflow profile is needed, but the part should be supported against vibration in high-G environments.
