1500W Zener TVS for automotive bus protection
The 1.5KE170AHB0G: Its 234V maximum clamping voltage at 6.7A peak pulse current (10/1000µs waveform) protects downstream electronics from load-dump, inductive kickback, and ESD transients on 145V nominal rails. The 162V minimum breakdown voltage and 145V reverse standoff rating mean this diode starts conducting safely above the normal operating voltage, staying out of the signal path until a transient arrives. It is a unidirectional device with a single protection channel.
DO-201 axial package and temperature range
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE170AHB0G mounts into a standard 0.100-inch pitch board layout with the cathode band marking the polarity. The junction temperature range spans -55°C to 175°C, covering the full automotive under-hood and engine-bay thermal profile without derating. The bulk packaging suits hand-insertion or wave-solder assembly; no reel or tape carrier is involved. Power line protection is not supported — this is a transient suppressor, not a mains-side protector.
Active lifecycle and sourcing posture
For volume procurement, the AEC-Q101 qualification means the part ships with full automotive PPAP documentation and lot traceability, which is required for Tier-1 and OEM production lines. No pin-compatible alternative is listed by the manufacturer; the 1.5KE series covers other voltage ratings if the clamp level needs adjustment.
