MOSFET relay offers 75 percent higher load current
A small MOSFET relay from Omron Electronic Components Europe combines a high current rating (200-V, 0.35-A) and high ambient operating temperature range in a small-sized surface mount format, making it an excellent choice for test and measurement equipment.
The G3VM-201WR – a 200-V addition to Omron’s existing MOSFET relay series – has an improved P-SON four-pin terminal pad design that ensures high heat dissipation, while its improved terminal shape results in better solder joints.
At just 3.4- by 2.1 mm, and with an ambient operating temperature ranging from –40°C to +110°C, this compact device can realise a current load of 75 percent higher (0.35-A, 49-mA/mm2) than a comparable SOP4 type relay (0.2 A, 7.3 mA/mm2). It also features fast turn on and turn off times of 1ms.
The Omron MOSFET relay series also includes VSON and SVSON components (capable of handling load voltages up to 100 V), for applications where space is critical.
The G3VM series offers energy saving with a standard driving current of 2 to 15 mA. Ultrasensitive models are also available featuring drive currents as low as 0.2 mA (maximum).
MOSFET relays use a light signal instead of moveable contacts thereby avoiding any reduction of life caused by contact wear, substantially increasing operational life. Further as there are no mechanical contacts, MOSFET relays eliminate switching noise, a potential problem associated with electromechanical relays.
As MOSFET relays use light signals they offer great I/O isolation. The standard models offer 2500 Vrms between input and output. Superior 5000 VAC products are also available, and 3750 VAC products have also been added to the SOP package series.
MOSFET relays can withstand external surge current without the addition of snubber circuit. Under normal conditions, the typical leakage current is about 1 nA or below. No movable parts also ensure excellent shock and vibration resistance.
