Photocouplers enhance white goods safety
A Toshiba Electronics Europe product story
Edited by the Electronicstalk editorial team Jul 13, 2007
Power triac photocoupler has reinforced insulation and boasts 5kV isolation voltage for AC safety applications.
The TLP3082 power triac photocoupler from Toshiba Electronics Europe features reinforced insulation and 5kV isolation voltage for AC safety applications.
Specified with an off-state voltage of 800V, Toshiba's TLP3082 consists of a zero-crossing (ZC) phototriac optically coupled to a gallium arsenide (GaAs) infra-red emitting diode.
Maximum inhibit voltage for zero-crossing is just 20V, contributing to reduction of EMI emissions.
The LED and triac are encased in a single 6-lead plastic DIP, offering a compact solution which conforms to the clearance and creepage requirements of international standards.
The TLP3082 is recognised by UL 1577 and can be used to ensure conformance to IEC/EN/DIN EN60747-5-2 safety standards.
The new device is designed for use in a wide range of applications, in particular those that require control of 240V mains voltages.
These include washing machines, dishwashers, heaters, office automation, industrial systems, solid state relays (SSRs) and other AC power and triac driven applications.
The TLP3082 features a low trigger current of just 10mA, and can deliver a maximum on-state output current of 100mA.
Maximum leakage in inhibited state is 600uA.
