Toshiba launches high noise immunity 800V couplers
Toshiba Electronics has announced two new miniature photocouplers that are ideal for office equipment, home appliances, solid state relays and other applications demanding high impulse noise immunity.
The Toshiba’s new photocouplers consist of a GaAlAs LED that is optically coupled to a triac output photocoupler and can be used to control current in both forward and reverse directions. Minimum peak off-state voltage is rated at 800V.
Maximum trigger LED currents for the TLP3782(S) and TLP3783(S) are 10mA and 5mA respectively. Input forward current is rated at 30mA, and maximum on-state current is 100mA (at 25ºC).
The two devices are housed in a compact 6-pin DIP package measuring just 7.1mm x 6.4mm x 3.6mm and are designed to meet UL and reinforced insulation class VDE international safety standards. Each photocoupler will operate at temperatures ranging from -40ºC to 100ºC.
