Automotive-grade transient suppressor for 18.8 V rails
The 1.5KE22CAHA0G: The breakdown voltage range starts at 20.9 V minimum, ensuring the device remains transparent during normal operation and only conducts during overvoltage events.
AEC-Q101 qualification and temperature range
Qualified to AEC-Q101, this part is screened for automotive-grade reliability including extended temperature cycling and high-temperature reverse bias stress. The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles without derating. Marked as Automotive grade in the series, it supports PPAP documentation requirements for Tier-1 automotive suppliers.
Through-hole DO-201 package for board-level robustness
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE22CAHA0G provides a mechanically robust mounting suitable for high-vibration environments. The supplier device package is DO-201, with leads that insert into plated through-holes on the PCB and can be wave-soldered or hand-soldered. Supplied in Tape & Box (TB) format, the axial leads are oriented for automated insertion equipment.
Bidirectional single-channel protection
A single bidirectional channel protects both polarities of the 18.8 V rail, eliminating the need for back-to-back series diodes in AC or dual-supply applications. The base product number 1.5KE22 identifies the 22 V nominal breakdown family; the CA suffix indicates bidirectional clamping, and the HA0G suffix denotes the automotive-qualified, RoHS-compliant variant.
