Key Features
- 60 V maximum load voltage with 0.5 A continuous output current for low-power DC load switching without contact bounce or wear
- MOSFET output with optocoupler input isolation providing galvanic separation between control and load circuits in PCB-mount DIP package
- SPNO (normally open) single-pole configuration enabling direct replacement of mechanical relay contacts in signal-level switching applications
Applications
G3VM-61B1 is used to switch low-voltage DC loads in test and measurement equipment, programmable logic controllers, and medical device signal routing where mechanical relay contact bounce would introduce measurement errors. The optocoupler input isolation allows 3.3 V or 5 V microcontroller outputs to control 60 V DC load circuits without direct electrical connection. Its PCB-mount DIP package integrates directly into through-hole or mixed-assembly PCB designs, replacing reed relays or small electromechanical relays in data acquisition, automatic test equipment, and industrial sensor signal switching applications.

Frequently Asked Questions
How does G3VM-61B1 perform in a DC switching application compared to an electromechanical relay at the same 0.5 A rating?
G3VM-61B1 switches in under 1 ms with zero contact bounce, compared to 5 ms to 20 ms bounce time for an electromechanical relay at 0.5 A. The MOSFET output eliminates contact arcing, extending operational life to over 100 million switching cycles versus 100,000 to 1 million cycles for mechanical contacts. On-resistance is typically 1 Ω to 3 Ω, causing a voltage drop of 0.5 V to 1.5 V at full 0.5 A load—acceptable for most signal-level DC switching but must be factored into power budget calculations.
What input drive current does G3VM-61B1 require from a 3.3 V microcontroller GPIO pin?
G3VM-61B1 requires a typical LED input forward current of 5 mA to 10 mA to guarantee turn-on. From a 3.3 V GPIO with a 1.2 V LED forward voltage, the series resistor should be (3.3 V − 1.2 V) / 7.5 mA = 280 Ω, so a standard 270 Ω or 300 Ω resistor ensures reliable activation. Most 3.3 V GPIO pins source 4 mA to 8 mA, which meets the minimum trigger requirement. A buffer stage or transistor driver is recommended when the GPIO current drive budget is marginal.
In which industrial or medical applications does G3VM-61B1 offer an advantage over reed relays?
G3VM-61B1 outperforms reed relays in vibration-prone environments such as portable medical monitors, industrial machinery mounted on vibrating frames, and automotive diagnostic equipment where mechanical shock can cause reed contact chatter or permanent damage at accelerations above 10 g. The solid-state MOSFET output has no moving parts, guaranteeing stable switching performance from -40°C to +85°C with no sensitivity to magnetic fields that can inadvertently actuate reed relays in proximity to transformers or motors.
Can G3VM-61B1 switch AC loads, and what is the maximum AC voltage it supports?
G3VM-61B1 supports both AC and DC loads up to 60 V peak (60 V AC maximum). The MOSFET output switches bidirectionally, handling the positive and negative half-cycles of AC signals at frequencies from DC to several hundred Hz. Maximum continuous load current is 0.5 A RMS for AC loads. This makes it suitable for low-voltage AC signal routing in audio test equipment and small appliance control circuits, though 60 V AC limits it to low-voltage Class 2 circuits and it should not be used on mains voltage wiring.
