1500W bidirectional transient suppressor in DO-13
The bidirectional configuration means a single device clamps both positive and negative transients, simplifying board layout for AC-coupled or floating signal lines where polarity is not fixed. Housed in a DO-13 through-hole package, the part is suited for point-of-use transient suppression on power rails or I/O lines in industrial, avionics, and general-purpose equipment.
The 113V maximum clamping voltage at 13.3A peak pulse current sets the upper voltage the protected circuit sees during a surge — downstream components must withstand at least this level without damage. The 77.9V minimum breakdown voltage ensures the device starts conducting before the rail reaches destructive levels, with a 70V standoff that leaves margin for nominal 48V or 60V DC buses. No power line protection rating means this part is intended for signal or low-power rail transient suppression, not primary AC mains clamping.
Active production — no obsolescence watch needed
