High temperature ultra-miniature photocoupler suits power supplies and programmable controllers

The TLP285 offers an isolation voltage of 3.75kV and is rated for operation at temperatures from -55°C to 110°C. The creepage distance and clearance increased to min. 5mm.

Supplied in an ultra-miniature SOP4 package, the photocoupler has dimensions of just 4.4mm x 2.6mm x 2.1mm.

Toshiba’s new coupler consists of a GaAs infrared LED that is optically coupled to a phototransistor. Minimum current transfer ratio is 50%, while collector-emitter voltage (VCE) is rated at 80V. Maximum operating insulation voltage is 707Vpk, while highest permissible overvoltage is 6000Vpk.

The new device is fully approved to all relevant UL, BS, EN and VDE safety standards including UL1577, BS EN 60065: 2002, BS EN 60950-1: 2006 and EN60747-5-2.
