Toshiba TLP628 Manuals

The TLP628, −2, and −4 are TOSHIBA photocouplers which use a gallium arsenide infrared emitting diode optically coupled to a phototransistor. The TLP628−2 offers two isolated channels in a eight lead plastic DIP package, while the TLP628−4 provide four isolated channels per package.

This document introduces the features and characteristics of the TLP628, TLP628−2, and TLP628−4. They are photocouplers consisting of a gallium arsenide infrared emitting diode and a phototransistor. These products have a collector-emitter breakdown voltage of up to 350V and a current transfer ratio of over 50%. The TLP628−2 has two isolated channels, while the TLP628−4 has four isolated channels. The packages of these products are eight-lead plastic DIP package and multi-lead package respectively.

TLP628, TLP628−2, TLP628−4 are Toshiba's photocoupler products, consisting of a gallium arsenide infrared emitting diode optically coupled to a phototransistor with a 350V high voltage of collector-emitter breakdown voltage. TLP628−2 offers two isolated channels in an eight-lead plastic DIP package, while TLP628−4 provides four isolated channels in one package of the same type.

The TLP628, TLP628-2 and TLP628-4 are high-isolation (AC 5 kVRMS.min) photocouplers with GaAs infrared LEDs and silicon phototransistors and are ideal for use in high-voltage or high-power applications.
