1. Applications
• Measuring Instruments • High-Speed Memory Testers • High-Speed Logic IC Testers • ATE (Automatic Test Equipment) • Probe Cards 2. General
The TLP3475W photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a
WSON4 package. The TLP3475W features a low CR product and extremely low on-state resistance,and thus
delivers high on-state current. Additionally, the TLP3475W offers low insertion loss of a high-frequency
signal and thus prevents the degradation of a rapidly rising signal. The TLP3475W also features low off-state
current and low output pin capacitance, making it suitable for high-frequency measuring instrument applications. 3. Features
