Is there a pin-compatible replacement for PESD5V0S1BB,115?

Yes, parts like PESD5V0V1BB,115 and PRSB6.8SM are in the same SOD523 package and are pin-compatible. However, their electrical parameters, especially power handling, differ and must be verified.

What risks should I check before replacing PESD5V0S1BB,115?

Key risks include mismatched power ratings (PPPM), peak pulse current (IPPM), and clamping voltage (VCL). A lower-rated part may fail under the same transient conditions. Always verify these against your circuit's protection requirements.
