100 V standoff, 179 V clamp — single-channel Zener TVS
SMBJ100CE3/TR13 is a bidirectional Zener TVS diode from Microchip Technology, rated for a reverse standoff voltage of 100 V and a maximum clamping voltage of 179 V at a peak pulse current of 3.4 A (10/1000 µs waveform). The 600 W peak pulse power rating covers common surge events on 100 V rails — think industrial sensor supplies, telecom line drivers, or DC bus protection in motor drives.
DO-214AA SMB footprint and temperature range
Housed in a DO-214AA (SMB) surface-mount package, the part suits reflow assembly and shares a footprint with many SMB-packaged TVS diodes — a direct swap candidate when the scorch mark points to a failed clamp on a 100 V rail.
Supplied in Tape & Reel for automated pick-and-place; the base product number SMBJ100 is common across the SMBJ family, so cross-referencing a BOM line against a different voltage variant is straightforward.
