Bidirectional 1.5 kW TVS in a through-hole axial package
The 1.5KE8.2C-B: Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), it mounts through-hole and is intended for general-purpose circuit protection where bidirectional clamping is needed.
Clamping voltage and peak current — what they mean for your rail
The 12.71 V clamp voltage at 125.6 A peak pulse means downstream components rated for 15 V or higher see a safe voltage during a surge event — the TVS absorbs the energy rather than passing it through. Rated for 1500 W of peak pulse power, this part handles substantial surge energy in a 10/1000 µs waveform, typical for industrial transient protection on signal or low-power supply lines.
Lifecycle reality — obsolete, sourced through independent channels
For a BOM line requiring this exact clamp voltage and package, a spot-market buy is the only path — expect to work with a broker who can verify date codes and screen for counterfeits.
Package and integration note for the DO-201 axial footprint
The DO-201AA / DO-27 axial body has a standard 0.042-inch lead diameter; the through-hole footprint requires 0.052-inch plated holes on a 0.400-inch lead spacing. Bulk packaging means parts are loose in a bag — no tape-and-reel for automated insertion. Hand placement or tube-fed insertion is typical for low-volume or rework scenarios. Bidirectional construction (single device, two Zener junctions back-to-back) eliminates the need to orient the part on the board — polarity is irrelevant, which simplifies assembly in high-vibration environments.
