Solid State Photo-Coupled Relay (Photorelay) SPST-NO (1 Form A) 4-SOP (0.179", 4.55mm) The G3VM-61VY3(TR05) is a single-pole, single-throw normally open (SPST-NO) solid-state relay that uses an LED input and MOSFET output to switch AC or DC loads without mechanical contacts. It provides fast, silent, and highly reliable switching in a very small surface-mount package. Key Characteristics Relay Type: Solid State Relay (Photorelay) Contact Form: SPST-NO (1 Form A) Output Type: MOSFET Load Voltage: Up to 60 V AC/DC Load Current: Up to 700 mA On-Resistance: ~2 Ω max Input Control: LED-driven (low current DC input) Isolation Voltage: ~3.75 kV (input to output) Package: SOP-4 surface-mount (compact form factor) Packaging Option: TR = Tape & Reel for automated assembly How It Works The input LED is energized with a small DC current. It activates an internal photo-coupler. This drives a pair of MOSFETs, turning the load ON or OFF. No mechanical movement → no arcing or contact wear. Key Advantages Silent operation (no clicking sound) Very long life (no mechanical parts) Fast switching speed Compact size for dense PCB layouts Low leakage and stable performance Typical Applications Semiconductor test equipment Industrial control systems Battery-powered devices Data acquisition systems Communication and measurement circuits General-purpose signal switching #CommonPartsLibrary #Relay #SSR #G3VM
