Zener TVS diode, 1500W peak pulse, 70.1V standoff
The 1.5KE82A_R2_00001: Its 70.1V reverse standoff voltage (Vrwm) defines the maximum continuous DC voltage the diode can block without conducting — a 48V or 60V bus sits safely below this threshold.
What the 1500W rating means for your protection budget
The 1500W peak pulse power (1.5kW) is specified for a 10/1000µs exponential waveform — the standard TVS test pulse. For a shorter transient (8/20µs, common in ESD or lightning surge), the diode can absorb significantly more peak power before the junction temperature limit is reached. The 113V clamping voltage at 13.3A means a 70V rail sees the transient clipped to 113V maximum, protecting downstream components rated for 120V or higher.
Sourcing an obsolete TVS for legacy BOM support
Panjit has marked the 1.5KE82A_R2_00001 as Obsolete. No official successor order code is recorded from the manufacturer. The tape-and-reel (TR) and cut-tape (CT) packaging options are both available through this channel. Buyers should verify the date code and lot traceability with the sourcing desk before committing the BOM line.
