SFH636 Description

Short technical summary and product information.

The SFH636 from Infineon Technologies is a high-speed optocoupler designed for reliable signal transmission between electrically separated circuits. It features a GaAlAs infrared emitting diode coupled to an integrated photo detector with a high-speed transistor. This configuration allows for data transmission rates up to 1.0 MBit/s.

 

The device boasts an isolation test voltage of 5300 V RMS and a high common-mode rejection ratio (CMR) of 10 kV/ms. The open collector output and TTL compatibility make it suitable for various digital interface applications. Its DIP-6 package is designed for through-hole mounting.

 

Key electrical characteristics include a typical CTR of 19% at 16 mA forward current, a maximum reverse voltage of 3.0 V, and a maximum DC forward current of 25 mA. The power dissipation for the input is 45 mW, and for the output is 100 mW. The optocoupler also offers a typical dV/dt of 10 kV/µs, enhancing its noise immunity.

 

Applications for the SFH636 include IGBT drivers, data communications, and programmable controllers where robust isolation and high-speed signal transfer are critical.
