No power line protection means this is a signal-rail or DC-bus clamp, not a mains AC protector — it shunts fast transients, not sustained overvoltage. ## Package and board fit — DO-201 axial for through-hole assembly DO-201AA / DO-27 axial package, supplier device package DO-201 — the glass-passivated body stands up to reflow or wave-solder thermal profiles. Through-hole mounting means the leads insert into plated through-holes; the axial body lays flat or stands upright depending on the board layout and clearance requirements. Supplied in tape and reel — the axial leads are taped per EIA-296 for automated insertion, not hand-load.","metaTitle":"1.5KE250AH Taiwan Semiconductor Zener TVS, 1500W, 214V","metaDescription":"1.5KE250AH AEC-Q101 automotive Zener TVS diode, 1500W peak pulse, 214V standoff, 344V clamp.
