Toshiba photocouplers boast ultra-minature packages
Ideal for use in compact switching power supplies, home appliances and industrial devices, Toshiba Electronics Europe's new low input current-type transistor output photocouplers come in ultra-miniature SO6 and SO4 packages and support operation in temperatures of up to 125°C.
By employing Toshiba’s high-output LEDs, the photocouplers ensure high current transfer ratios of up to 600% both at conventional input currents of 5mA and at low 0.5mA LED currents (VCE=5V).
The photocouplers significantly contribute to a reduction in power consumption when using high voltages such as 100V AC, by reducing the LED current at the photocoupler. TLP182 and TLP292 support AC input and house two high-output LEDs, while TLP183 and TLP293 support DC input and house a single LED.
TLP182 and TLP183 are supplied in 4-pin SO6 surface mount packaging with 2,54mm pitch, that requires board mounting dimensions of 7.0mm x 3.7mm and has a height of 2.3mm. TLP292 and TLP293 are supplied in the smaller SO4 package with 1,27mm pitch, which requires board mounting dimensions of just 7.0mm x 2.6 mm and has a height of 2.1mm.
All the devices have a guaranteed minimum creepage and clearance distance of 5mm, a minimum breakdown voltage (BVs) of 3750Vrms, and they are rated for a wide operation temperature range from -55°C to 125°C.
