miniature photocouplers
Toshiba has announced two miniature photocouplers that are ideal for office equipment, home appliances, solid-state relays and other applications demanding high-impulse noise immunity.
The TLP3782 and TLP3783 zero-crossing devices provide minimum isolation voltages of 5,000Vrms between sensitive logic and AC currents.
Each device is rated for typical impulse noise durability of 1,500V.
They consist of a GaAlAs LED that is optically coupled to a triac output photocoupler and can be used to control current in 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 25C).
The two devices are housed in a compact six-pin DIP package, measuring 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 -40C to 100C.
