Regarding the domestic substitution of PESD5VOHS-SF and ESD7501MUT5G with ULCO521CLV
Leiditech ULC0521CLV is a highly cost-effective 5.0V low clamping voltage (VC), single-channel bidirectional, low-capacitance ESD diode, available in an ultra-small DFN0603 package (SOD962-2 / 0201 / X3DFN2). ULC0521CLV can serve as a complete replacement for Nexperia's PESD5V0HS-SF, Onsemi's ESD7501MUT5G, Texas Instruments' ESD451DPLR, and KEC's PS05TBEL2D.
