The Toshiba TLP192G consists of a gallium arsenide infrared emitting diode optically coupled to a photo-MOSFET in a 6-pin SOP package. This photorelay has a characteristic of high-withstanding voltage between output pins which enables TLP192G to be applied in hook relays and dial-pulse for modems and facsimiles. Moreover, the TLP192G is used for PCMCIA-compliant card modems because the maximum mounted height of SOP package is as small as 2.1 mm.

Frequently Asked Questions
What is the minimum DC isolation voltage provided by the TLP192G?
The isolation voltage is a rated 1500 Vrms minimum, suitable for use in various relay applications.
What is the maximum allowable forward current derating when operating at elevated temperatures?
Below an ambient temperature of 25°C, the Forward current derating rate is specified as 0.5 mA/°C.
Does this photorelay support integration into standard PC cards?
Yes, it supports use with PCMCIA-compliant card modems due to its small SOP package height of only 2.1 mm.
What safety precautions must be followed when handling the components?
Because Gallium arsenide (GaAs) is used, treat dust and fumes as toxic. Do not cut or pulverize the products; follow appropriate disposal regulations.
