Photocouplers offer high current transfer ratio
1 min read
A new family of low input current photocouplers has been introduced by Toshiba Electronics Europe.
Available in miniature SO6 and SO4 packages, the TLP182, TLP183, TLP292, TLP293 support operation in temperatures up to 125°C, allowing reliable use in compact switching power supplies, home appliances and industrial devices such as PLCs and inverters.
Utilising 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 TLP182 and TLP292 support ac input and house two high output leds, while TLP183 and TLP293 support dc input and house a single led.
The TLP182 and TLP183 are supplied in 4pin SO6 surface mount packaging with 2.54mm pitch, which requires board mounting dimensions of 7 x 3.7mm and has a height of 2.3mm.
The TLP292 and TLP293 are supplied in the smaller SO4 package with 1.27mm pitch, which requires board mounting dimensions of 7 x 2.6mm and has a height of 2.1mm.
