VISHAY SFH6345 High-Speed Optocoupler, DIP, 1 Channel
High-speed optocoupler with 1 channel, DIP package, TTL compatible. Ideal for industrial isolation and IPM drivers.
The VISHAY SFH6345 is a high-performance analogue optocoupler designed for reliable signal isolation in demanding industrial and consumer applications. This component integrates a GaAlAs infrared emitting diode with a high-speed photo detector, comprising a photo diode and a high-speed transistor. The incorporation of an additional Faraday shield enhances input-output dV/dt immunity, allowing for stable operation in environments with high electrical noise.
With a data rate of 1Mbaud and the ability to transmit signals up to frequencies of 2MHz, this optocoupler is well-suited for industrial communication bus isolation, isolated drive circuits, and IPM (intelligent power module) drivers. The open-collector output and TTL compatibility ensure seamless integration with digital logic circuits, while the absence of a base connection simplifies design. The device offers good CTR linearity relative to forward current and low coupling capacitance, contributing to consistent performance across varying conditions.
