The 1.5KE110AHA0G: Its 94 V reverse standoff voltage means it sits across a nominal 48 V or 72 V bus without conducting leakage current, then clamps transients at 152 V maximum — well below the typical 200 V breakdown of downstream MOSFETs and DC-DC converters in automotive and industrial power stages. AEC-Q101 qualification confirms the part has passed the full automotive stress suite: high-temperature reverse bias, temperature cycling, and ESD robustness.
Through-hole DO-201 — hand-solderable and board-serviceable
The DO-201AA (DO-27) axial-lead package is a through-hole form factor that fits a 1.0 mm (0.040 inch) diameter hole on a standard 0.100-inch pitch. The leads are tin-plated copper — solderable with a standard iron or wave process, and easy to replace in rework without hot-air equipment. The body diameter is about 5.3 mm, so adjacent parts on the same axial row need 7–8 mm centre-to-centre spacing to avoid lead-to-lead shorting during hand soldering. Tape and box packaging means the parts come in an ammo pack with the leads formed and taped — compatible with automatic insertion machines that feed axial components, but also easy to cut loose for bench prototyping. The 1500 W pulse rating at 10/1000 µs is the standard TVS test waveform; the actual energy capability at shorter pulses (8/20 µs) is higher by roughly the square root of the pulse-width ratio, so this part also handles lightning-induced surges per IEC 61000-4-5.
Active production — no end-of-life risk for current designs
The base product number is 1.5KE110, which means the same silicon is also available in other package variants (e.g. surface-mount DO-214AB) and in bidirectional configuration. The A0G suffix on this order code specifically denotes the DO-201 through-hole package in tape-and-box format — confirm the package and packing form match your pick-and-place or hand-loading process before committing the line.
