The breakdown voltage range starts at 9.5V, so the rail must stay below 8.55V during normal operation. That 14.5V clamp is the voltage the downstream IC sees — it must stay below the abs-max rating of the protected device. ## Package and board-fit — through-hole, not reflow The DO-201AA / DO-27 axial package is a through-hole part, not a surface-mount reflow component. The leads are formed and inserted into plated-through holes — the rework tech needs a soldering iron or wave solder, not a hot-air rework station. The supplier device package is DO-201, which is the standard JEDEC outline for this power class. ## Unidirectional Zener — one channel, one direction This is a unidirectional TVS with one channel — it clamps positive transients relative to ground. For bidirectional protection (e.g., on an AC line or a signal that swings below ground), you need two devices back-to-back or a bidirectional part. The power line protection flag is No, so this is designed for DC rail protection, not for AC mains.","metaTitle":"1.5KE10AHA0G TVS Diode, 1500W, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE10AHA0G automotive Zener TVS, 1500W peak pulse, 8.55V standoff, DO-201 axial.

Any standard 1.5KE10A (non-automotive) variant is pin-compatible — same DO-201 package, same breakdown and clamping voltages — but lacks the AEC-Q101 automotive screening and the -55°C to 175°C temperature range qualification.
