OCS30
Optical PNPN Switches
GENERAL DESCRIPTION
The OCS30 is an optical switch formed by combining an infrared light emitting diode and a PNPN element (photothyristor) that can withstand high voltages. The device is encased in an 8-pin plastic package. The output PNPN element of the OCS30 forms a bridge configuration,giving the device rectification capabilities.
FEATURES
?Optical switch with photocoupler type 1 ￥ 1 ￥ 2 W (single) bridge ?Available for direct connection to subscriber line
?Total electrical isolation of drive circuit and channel circuit
?Protection function eliminating need for power outage countermeasures ?Simple polarity agreement
?
UL recognized — File number: E86831
APPLICATIONS
?Electronic automatic exchange ?Key telephone system ?Optically coupled circuits
