| E2P0042-37-X2 PHOTOCOUPLERS This version: Jan. 1998 Previous version: May. 1997 OCS37 electronic components OCS37 Optical PNPN Switches GENERAL DESCRIPTION The OCS37 is an optical PNPN switch, combining an infrared light emitting diode and PNPN elements (photothyristors) in a two-channel configuration. Encased in a 8-pin plastic package, the device is capable of withstanding high voltages. The OCS37 consists of two output PNPN elements (bidirectional circuits), which are housed in a single package. Each of the two elements can be controlled independently. FEATURES * Forward blocking voltage (VBO): 320 V (Min.) * Trigger input current (IGO): 11 mA (Max.)
