TVS diode for 7 V rail protection
The 1.5KE8.2A-E3/54: It clamps a 7.02 V reverse standoff rail at 12.1 V, with a breakdown voltage window starting at 7.79 V. This is a through-hole axial-lead part in the DO-201AA (DO-27) package, covering general-purpose transient suppression on DC power or signal lines where a single unidirectional clamp is needed.
Peak pulse rating and clamping behaviour
At the 10/1000 µs test pulse, the device handles 124 A peak pulse current before the voltage rises to the 12.1 V clamp level. The 1500 W rating is the product of clamp voltage and peak current — a standard benchmark for comparing TVS diodes in this package class.
Packaging and shelf-life considerations
Available in Tape & Reel (TR) or Cut Tape (CT) options. The DO-201AA axial lead form is not moisture-sensitive — no dry-bake required before reflow or hand-solder. Store the reels in a standard ESD-safe cabinet; the leads are tin-plated and solderable per JEDEC standards.
