Comparatively, the initial contact resistance (CR) of mechanical relays is lower than MOSFET relays. However, the CR of mechanical relays increases with number of operations. MOSFET relays, on the other hand, have stable ON resistance and ensure well over 500 million operations. Comparing the MOSFETs package, VSON, with an electromechanical relay G6L, the VSON MOSFET Relay offers a 95% space saving.
