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

Buck Switching Regulator IC Adjustable 1 Output 1000mA SOT-23-6 The LGS5145 is a step-down DC/DC regulator with internal switching, featuring SKIP control mode, which combines low quiescent current with high switching frequency to achieve high efficiency over a wide range of load currents. The SKIP mode uses a short “burst” cycle to switch the inductor current through the internal power MOSFETs, followed by a sleep cycle in which the power switch is turned off and the load current is supplied by the output capacitor. At light loads, the burst cycle is a fraction of the total cycle time, minimizing the average supply current and greatly improving efficiency at light loads. The LGS5145 has a wide input voltage range of 4.5V55V, minimizing the need for external surge suppression components.The LGS5145 features an integrated low resistance 0.6Ω high-side power MOSFET that provides at least 1A of output current capability with excellent load and line transient response. Junction temperature range from -40°C to +125°C ■ All ports are ESD protected to 3000V (HBM). ■ Wide input voltage range: 4.5V-55V ■ 600mΩ High Side Metal Oxide Semiconductor Field Effect Transistors ■ At least 1000mA continuous current output capability ■ Up to 90% efficiency ■ SKIP mode provides very high light load efficiency ■ 1.2MHz fixed operating frequency ■ Internal compensation helps reduce solution size, cost and design complexity ■ Supports capacitive start for large loads ■ Cycle-by-cycle overcurrent protection ■ Output short circuit protection ■ thermal shutdown protection ■ Available in ultra-small package SOT23-6 package #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Voltage-regulator #Switching-regulator
