Low input current type transistor output photocouplers

Toshiba have today announced the launch of a new line-up of low input current type transistor output photocouplers that guarantee high Current Transfer Ratio at low input current. The "TLP182" and "TLP183" will be available in SO6 packages and the "TLP292" and "TLP293" in small SO4 packages. Mass production is scheduled to start at the end of August, 2013.

The photocouplers all incorporate Toshiba's original high output infrared LEDs and guarantee the same CTR at 0.5mA input current and at 5.0mA input current, making it possible to reduce the current to the LED and secure lower power consumption. The LED's stable output under high ambient temperature guarantees operation at up to 125°C, allowing for reliable use in industrial devices, compact power supplies and other applications that generate high levels of heat.

Target applications for the new TLP182, TLP183, TLP292 and TLP293 photocouplers include switching power supplies, industrial devices such as PLC and inverters, and AC line detection for home appliances.

Key features:

  • Guaranteed high CTR (50 to 600%) at low input current (IF) of 0.5mA,
  • Guaranteed operation temperature [Topr(Max)] up to 125°C,
  • Smaller and thinner package produced in high efficiency production lines (SO6 and SO4.

Main specifications:
