Electrical Specifications PMA637
| Parameter | Value | Notes |
|---|---|---|
| Package | SMD4 | The PMA637 is a 1-Form A solid state relay in a 4 pin SMD package that employs optically coupled MOSFET technology to provide 3750V / 5000V of input to output isolation. The optically coupled input is controlled by a highly efficient GaAlAs infrared LED and MOS FETs on the output side. |
