PCB Mounting

PCB mounting solid state relay can be divided into Socket Mounting Type SSR (or Plug-in Mounting Type) and Bracket Mounting Type SSR (or Flange Mounting Type). The plug-in solid-state relays with many package standard (like SIP, Mini-SIP, and DIP), can be directly soldered on the printed circuit board, relying on natural cooling, without the need for a heat sink; the flange mounting solid state relays require the additional metal plate or heat sink to dissipate heat.
