1500 W transient suppressor — 7.02 V standoff, 12.1 V clamp
The 1.5KE8.2A-E3/73: Breakdown occurs between 7.79 V minimum and the clamp ceiling, so the protected circuit sees no more than 12.1 V across the diode during a 124 A peak pulse event. This is a unidirectional device — one channel, cathode band oriented for DC line protection.
Through-hole axial package — DO-201AA body
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE8.2A-/73 mounts through-hole on the board. The 1.5KE supplier device package code matches the standard TransZorb footprint — the leads insert into 1.0 mm diameter plated-through holes on a 0.4-inch lead spacing.
Active lifecycle — no obsolescence watch needed
The Tape & Box (TB) packaging (/73 suffix) ships in ammo-pack format — the leads are formed and taped for automatic insertion, but the box stores flat on the shelf without reel tension. Store the reels dry; the DO-201AA body is not moisture-sensitive, so no bake required before wave solder.
