The Leiditech ULC0121CLV is a low-voltage (cutoff voltage 1.0V), low junction capacitance (0.2PF) ESD diode with a small package (DFN0603), serving as an electrostatic protection diode. The ULC0121CLV can replace the PESD1V2Y1BSF (Nexperia), ESDL2012MX4T5G (ON Semi), RClamp1011ZC (SEMTECH), and PS1201-D32 (PANJIT). The parameter comparison list is as follows:：

List Note: Vrwm: Reverse Turn-off Voltage, Vbr: Breakdown Voltage, VCmax@A: VC measured under the maximum IPP condition, Cj: Junction Capacitance, Features: 1CH: Single Path, Bi: Bidirectional. 

If you are currently using any of these products and need a domestic alternative, you can contact Lei Ma's sales team to request sample testing.
