The single unidirectional channel is polarity-specific — it protects one rail against positive transients; for bidirectional protection on AC or bipolar lines, two devices or a bidirectional variant is needed. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE12AH is hand-solderable or wave-solderable and suits prototyping, rework, and high-reliability point-to-point wiring. The tape-and-reel packaging option supports automated insertion for volume builds. Power line protection is not provided — this is a transient suppressor, not a continuous overvoltage clamp; it is intended for short-duration surge events per IEC 61000-4-5 or similar. ## Sourcing and lifecycle posture For BOM placement, the base product number is 1.5KE12; the 'AH' suffix denotes the automotive grade and specific packaging variant. Confirm the exact ordering code matches the reel quantity and temperature grade required for the line item.","metaTitle":"1.5KE12AH TVS Diode, 1.5kW, 10.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE12AH automotive TVS, 1500W peak pulse, 10.2V reverse standoff, AEC-Q101 qualified.
