Low input current-type transistor photocouplers drive down power consumption
TLP182, TLP183, TLP292, TLP293 support operation in temperatures of up to 125°C, allowing reliable use in compact switching power supplies, home appliances and industrial devices such as PLCs, inverters and other devices where they could be exposed to high temperatures.
By employing Toshiba’s high-output LEDs, the photocouplers ensure high current transfer ratios of up to 600% both at conventional input currents of 5 mA and at low 0.5 mA LED currents (VCE=5V).
The photocouplers significantly contribute to a reduction in power consumption when using high voltages such as 100 V 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 2.54 mm pitch, that requires board mounting dimensions of 7.0 mm x 3.7 mm and has a height of 2.3 mm. TLP292 and TLP293 are supplied in the smaller SO4 package with 1,27 mm pitch, which requires board mounting dimensions of 7.0 mm x 2.6 mm and has a height of 2.1 mm.
All the devices have a guaranteed minimum creepage and clearance distance of 5 mm, a minimum breakdown voltage (BVs) of 3750 Vrms, and they are rated for a wide operation temperature range from -55°C to 125°C.
