● Switching of DC only or both AC/DC

There are two kinds in switching load type. One is DC only type and the other is

AC/DC type. DC only type has one MOS FET. And AC/DC type has two MOS FETS.

These two MOS FETs connected series with source common, AC/DC bi-directional

signal switching is possible.

● High Reliability and Long life span

PhotoDMOS-FET Relay does not have the mechanical contact. Therefore there is no

defacement of the contact. And life is practically unlimited.

● Compact, thin, light and high density mounting

Due to compact (DIP/SMD or SOP package), thin and light, high density mounting

(reduction of mounting area and volume) is possible. The thickness of the SOP

package is around 2 mm. Mechanical relays cannot provide this kind of thinness.

● Calm

Due to Non-contact, there is no sound like mechanical relays.

● No chattering and Bounce

Due to Non-contact, there is no chattering and no bounce like mechanical relays.

● High switching speed

Due to semiconductor relays, high speed switching is available.

● Low Off-set voltage

● Control low-level analog signals

Due to MOS FET's output, Closed-circuit Off-set voltage is extremely low to enable to

control low-level analog signals without distortion.

● No need of the power supply to drive MOS FET

Since output MOS FETs are driven by photodiode array directly, a power supply to

drive output MOS FETs is not necessary. This results in easy circuit design and small

PC board area. PhotoDMOS-FET Relay

● Stable On-resistance

Due to semiconductor, On-resistance is stable comparing with mechanical relays.

● Low Off-state leakage current

● Controls various types of loads

● Control various types of load such as relays, lamps, Light emitting diodes, heaters,

motors, solenoids.

● Extremely high Input-Output isolation

Input and output are extremely isolated by the optical coupling.

● Vibration proof and Shock proof

Due to semiconductor, the products are free from vibration and shock.
