Omron G3VM Series PCB Mount Solid State Relays, 200 mA Load, Surface Mount Mount, 80 V Load

Omron G3VM Series PCB Mount Solid State Relays, 200mA Maximum Load Current, 80V Maximum Load Voltage - G3VM1139M

This PCB-mount solid-state relay provides a compact, surface-mounted switching solution for low-current DC circuits in industrial and electronic control environments. Designed for printed circuit board assembly, it uses a semiconductor output stage to perform single-pole single-throw normally open switching with minimal mechanical wear, making it suitable for frequent switching in automated systems.

Features and Benefits:

• 80V maximum load voltage enables moderate-voltage DC switching
  200 mA maximum load current supports low-power control circuits
  1 nA off-state leakage reduces unintended current draw
  1 Ω on-state resistance minimises voltage drop during conduction
  15 pF capacitance limits noise and crosstalk between terminals
  UL approval confirms recognised safety assessment for use

Applications

• Suitable for signal switching in factory automation controllers
  Ideal for interfacing sensors to control electronics
  Used for low-current power distribution in instrumentation
  Can be used for PCB-mounted relay replacement in Compact devices
  Used with driver ICs in industrial monitoring modules

What mounting method is required for PCB assembly?

The device uses a surface-mount Terminal style in a 4-pin SOP package for reflow soldering on standard pads.

How does the thermal environment affect operation?

Rated to operate between -20 °C and 85 °C, it maintains switching characteristics across typical industrial temperature ranges.

What type of semiconductor is used for the output?

The output stage employs a FET topology to provide solid-state conduction and fast switching performance.

How small is the component footprint for dense boards?

The package measures 2.54mm by 4.4mm with a height of 3.9 mm, allowing tight placement on populated PCBs.
