A single bidirectional channel protects both positive and negative transients on the same line — no need for back-to-back unidirectional diodes, which saves PCB area and reduces component count.
The tape-and-reel delivery suits automated pick-and-place assembly.
The SMBJ85CAE3/TR13 is itself the standard bidirectional 85V variant in Microchip's SMBJ series. Other manufacturers produce functionally equivalent bidirectional TVS diodes in the same DO-214AA package with the same 85V standoff and 600W rating — for example, Littelfuse's SMBJ85CA or Vishay's SMBJ85CA. Confirm the breakdown voltage window and clamping spec against your application before substituting.
600W peak pulse power per the 10/1000µs waveform. This is the maximum transient energy the device can absorb in a single pulse before the junction temperature exceeds the safe operating area.
