The 1.5KE8.2A B0G: It is a single-channel, unidirectional Zener-type TVS — the anode connects to ground and the cathode to the positive rail, so it only clamps positive overvoltage transients above the breakdown threshold. The DO-201 (DO-27 axial) package allows through-hole mounting, often seen in power supplies, telecom line cards, and industrial control boards where a replaceable, high-surge part is preferred over a surface-mount alternative.
Active production and supply posture
It is a standard catalog part in the 1.5KE series, which is widely stocked across distribution.
The DO-201AA / DO-27 axial leaded package measures roughly 9.5 mm body length with 0.96 mm diameter leads — standard for a 1.5 kW TVS. The through-hole footprint requires a 1.2 mm drilled hole per lead; the anode end is typically marked with a band. For high-reliability builds, the lead bend radius should not exceed the lead diameter to avoid stress cracks at the glass seal.
