MOS FET Relays
-
Substantial space saving offered in our VSON, and new S-VSON package size. -
Standard driving current is 2-15mA. Ultrasensitive type with driving current 0.2mA(max.) available. -
Realize the structure without contacts by sending light signal. Avoid the reduction of life caused by wear of contacts, and realize extended operational life.
-
- Small leakage current
- Can withstand external surge current, and not add the snubber circuit. Under normal condition, it is 1 nanometer A or below (GR, LR, PR type), and the leakage current is very small when close.
-
- High insulation
- It turns the voltage into the light, and transfers by the light signal, so it is electrical insulation. It not only can ensure that the Dielectric strength between input and output under normal condition is AC 2500V, but also realizes the serialization of upper 5000V product at the same time, and realize the high insulation.
-
- Excellent shock resistance
- All the internal parts use the casting method, and there is not movable part in it, so it has excellent shock resistance and vibration resistance.
-
- High-speed switching
- Comparing with the switching time of 3~ 5ms of mechanical relay, its switching time is shortened to 0.2ms(SSOP, USOP). Realize the quick response performance.
-
- Silent
- Avoid the switching voice caused by metal contacts of mechanical relay. Realize the function of silence.
-
- Control the micro analog signal correctly
- Comparing with the triac, it reduces the dead zone greatly. The input waveform of micro analog signal dose not distort basically and is converted into output waveform without distortion.
Structure and operational principle of MOS FET relays
-
- LED (light emitting diode)
- Photodiode dome array (PDA)
- MOS FET
-
- The LED lights when the current is connected at the input side.
- The light sent by the LED will be converted into voltage again when it is received by the photodiode .
- This voltage will be a gate voltage to drive MOS FET via control circuit.
