The 8.4A peak pulse current rating tells you the diode can sink that current without exceeding the junction temperature limit of 150°C.
Surface-mount DO-214AB (SMC) package is a common TVS footprint; the copper pad area under the cathode tab sets the thermal impedance for the 1500W pulse.
The SMCJ100A is a unidirectional TVS with the same 100V standoff and 1500W rating, while the SMCJ100CE3/TR13 is bidirectional. If your circuit requires bidirectional clamping (e.g., AC lines or differential pairs), this part fits; for a unidirectional DC rail, the SMCJ100A is the correct choice. Check the polarity marking on your existing board before substituting.
No — the reverse standoff voltage is 100V, far above a 5V rail. A 5V rail needs a TVS with a standoff voltage around 5-6V (e.g., SMCJ5.0A family). Using a 100V TVS on a 5V rail would leave the rail unprotected until the surge exceeds 100V, which is well past the damage threshold of 5V components.
The DO-214AB package is rated for standard reflow profiles per JEDEC J-STD-020.
