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.","metaTitle":"1.5KE170AHB0G TVS Diode, 1500W, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE170AHB0G Zener TVS diode, 1500W peak pulse, 234V clamp, AEC-Q101 automotive grade.
