The Toshiba TLP182 and TLP183 are low input current-type transistor output photocouplers utilizing the SO6 package. By employing Toshiba's original high-output LED, these products guarantee not only a high-current-transfer ratio at the conventional input current of 5 mA, but also at the same current-transfer ratio at the low LED current of 0.5 mA. Especially when utilizing LED current at 100 VAC and other high voltages, these products significantly contribute to a reduction in power consumption by reducing the LED current of the photocoupler. The TLP182 and TLP183 also support operation at an ambient temperature of 125°C, allowing for reliable use in industrial devices, compact power supplies, and other devices used in environments of severe heat. The smaller SO4 package is also available for the TLP292 and TLP293.
