The SMBJ170CA-13-F: The 170 V reverse standoff voltage means this part sits across a nominal 170 V DC bus or signal line and stays out of the circuit until a surge pushes the line above 189 V breakdown. Below that threshold, leakage is negligible — the diode is effectively invisible.
The SMB package measures roughly 4.6 mm x 3.6 mm, with a low profile that fits under conformal coating or in tight PCB stacks.
