The TOSHIBA TLP227G series consist of a gallium arsenide infrared
emitting diode optically coupled to a photo-MOS FET in a plastic
DIP package.
The TLP227G series are a bi-directional switch which can replace
mechanical relays in many applications.
TLP227G: 4 pin DIP(DIP4),1 channel type(1 form A)
TLP227G-2: 8 pin DIP(DIP8),2 channel type(2 form A)
Peak off-state voltage: 350V(min.)
Trigger LED current: 3mA(max.)
On-state current: 120mA(max.)
On-state resistance: 35(max.)
Isolation voltage: 2500Vrms (min.)
Isolation thickness: 0.4mm(min.)
