Analysis of ESD LC05CD replacing CM1214A-01
The customer mentioned that the market price of CM1214A-01 was very expensive, and he wanted to find a substitute. I found Leimao just in time, so I found it right.
Lei Mao's ESD models are complete and have good performance. But also can give good technical support.
The following is the wiring comparison between CM1214A-01 and LC05CD:
LC05CD pin-to-pin test data:
Pin 1 to Pin 3 = 1.2pF
Pin 2 to Pin 3 = 1.2pF
Pin 1 to Pin 2 = 0.6pF
Pin 2 to Pin 1 = 0.6pF
When using LC05CD, customers are advised to:
Pin 1 to I/O, Pin 2 to GND
or Pin 2 to I/O, Pin 1 to GND
Replace CM1214A-01 with LC05CD, and replace it directly without changing the board. Wiring according to the above figure.
