Photocouplers protect AC circuits
A Toshiba Electronics Europe product story
Edited by the Electronicstalk editorial team Aug 8, 2005
Toshiba Electronics Europe has expanded its range of photocoupler parts with two new devices that will reduce board space and improve performance in home appliances and other AC power applications.
Toshiba Electronics Europe has expanded its range of photocoupler parts with two new devices that will reduce board space and improve performance in home appliances and other AC power applications.
Supplied in miniature 8-lead plastic DIL packages, the TLP3616 and TLP3617 AC power triac couplers have dimensions of just 9.66 x 6.4 x 3.65mm.
Despite their small size, each device can deliver a maximum on-state output current of 1.2A RMS and operate with a minimum peak off state voltage of 600V.
Toshiba's TLP3616 and TLP3617 consist of a phototriac optically coupled to a gallium arsenide (GaAs) infra-red emitting diode.
Both couplers feature a minimum isolation voltage rating of 2500V RMS and are UL recognised in accordance with UL1577.
Trigger LED current is just 10mA.
The TLP3616 provides non-zero-crossing (NZC) functionality and the TLP3617 has a zero-crossing (ZC) configuration.
Target applications for the new devices include washing machines, dishwashers, heaters, industrial systems and other AC power and triac driven applications.
