General
The TLP3475R photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a
VSONR4 package. TLP3475R has a Built-in input resistor, which eliminates an external input resistor for space
saving. The TLP3475R features a low CR product and extremely low on-state resistance, and thus delivers high
on-state current. Additionally, the TLP3475R offers low insertion loss of a high-frequency signal and thus prevents
the degradation of a rapidly rising signal. The TLP3475R also features low off-state current and low output pin
capacitance, making it suitable for high-frequency measuring instrument applications.
