1500W Zener TVS for 7V rails
The 1.5KE8V2A-T: This part targets general-purpose circuit protection on low-voltage DC rails — 5V or 12V supplies where the standoff sits below the rail tolerance and the clamp catches transients before the downstream silicon sees overvoltage.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the 1.5KE8V2A-T as Obsolete. For BOM lines that require this exact order code, supply is available through independent surplus and excess inventory channels.
Key ratings and what they mean for fit
The 1500W peak pulse rating (10/1000µs) defines the energy-handling capability — a 124A surge at the clamping voltage of 12.1V is absorbed without device failure, making it suitable for protecting 7V-rated bus lines in industrial or telecom equipment. Breakdown voltage is guaranteed at 7.79V minimum, ensuring the TVS starts conducting before the protected circuit's absolute maximum rating is reached. Housed in the DO-201 (DO-27) axial leaded package, it mounts through-hole — a common footprint for board-level transient protection in power supplies and I/O lines.
