The junction temperature range spans -55°C to 175°C, covering hot engine-bay and cold-start extremes without derating. Power-line protection is not claimed (no internal filter structure), so this TVS is intended for transient clamping only — not for continuous overvoltage or surge suppression on mains inputs. The 1500 W rating at 25°C must be derated per the datasheet curve above that temperature. ## Through-hole DO-201 package fit Housed in the DO-201AA (DO-27) axial-leaded package, the 1.5KE400CAHB0G mounts through-hole on a PCB or terminal block. The DO-201 body is standard for 1.5 kW TVS diodes; its axial leads suit point-to-point wiring or board-level hand-assembly where surface-mount reflow is not practical. Supplied in bulk (tube or bag), not tape-and-reel — factor this into pick-and-place planning if automated insertion is intended; the axial format typically requires a forming fixture for machine feed.","metaTitle":"1.5KE400CAHB0G TVS Diode, 1.5kW, Bidirectional, DO-201","metaDescription":"1.5KE400CAHB0G bidirectional Zener TVS, 1500W peak pulse, 342V standoff, AEC-Q101 automotive grade.
