The 45.7 V clamp means the downstream circuitry sees a transient capped below 46 V, which is within the abs-max rating of most 40 V-rated DC-DC converters and linear regulators on a 24 V bus. ## AEC-Q101 — automotive qualification and the temperature envelope This is an automotive-grade part, qualified to AEC-Q101. The AEC-Q101 certification also means the part carries full PPAP documentation and lot traceability — relevant if your Tier 1 customer requires submission-level data for each production batch. ## DO-201 axial — field-swappable, no hot air needed The DO-201AA (DO-27) axial leaded package is a through-hole part. It mounts in a plated through-hole on the board and can be swapped with a soldering iron and a desoldering pump — no hot-air station, no reflow profile. The axial leads are long enough to form the bend for vertical or horizontal mounting, and the body is clearly marked with the polarity band for the bidirectional version (though bidirectional means no polarity concern in-circuit). The package is supplied in Tape & Box (TB) format, which is a cut-tape or ammo-pack variant — not reeled for automated pick-and-place, but fine for hand assembly or low-volume production runs. ## Active production — sourcing posture The AEC-Q101 documentation package (RoHS, REACH, PPAP-level data) is available on request.","metaTitle":"1.5KE33CAHA0G TVS Diode, 1500W, 28.2V, DO-201, AEC-Q101","metaDescription":"1.5KE33CAHA0G bidirectional Zener TVS from Taiwan Semiconductor. 1500W peak pulse power, 28.2V standoff, 45.7V clamp.
