Is there a pin-compatible replacement for BDFN2C051V?

Several parts like the BORN BDFN2C051L use the same 2-pin DFN-2L package and are likely pin-compatible. As bidirectional TVS diodes are non-polarized, physical compatibility is high, but electrical parameters must be verified.

What risks should I check before replacing BDFN2C051V?

Key risks include: 1) Clamping Voltage: A higher value offers less protection. 2) Capacitance: Higher capacitance can degrade high-speed signals. 3) Peak Current Rating: A lower rating may not handle expected surge events. Always verify these in the datasheet.
