Rutronik's portfolio includes the 25 MBd high-speed optocoupler VOIH72A from Vishay. The digital input and output of the single-channel component enables easy integration into digital systems, makes external driver stages and current limiting resistors obsolete, simplifies designs and reduces costs. The space-saving component combines a maximum pulse distortion of only 6 ns, a maximum supply current of 2 mA and a supply voltage range of 2.7 V to 5.5 V and is fast enough to support BUS systems such as SPI, as well as controllers for UPS systems or to transmit high-resolution PWM signals.
The optocouplers have no forward current or current limiting resistor at the input and no pull-up resistor at the output and deliver a high-speed data rate of up to 25 MBd. They feature digitally controlled LED drivers with high-speed IRED, coupled with integrated optical photodiode IC detectors. The components offer a guaranteed common mode interference immunity (CMTI) of at least 20 kV / µs, which, combined with a low switch-on threshold and low supply current, makes them ideal for noise suppression and the interruption of ground loops.
Suitable for use in an operating temperature range from -40 °C to +110 °C and installed in a small form factor SOIC-8 package, they are also pin-compatible with solutions from other manufacturers and are particularly suitable for use in new and existing designs for applications in data communication, pulse width modulation or the provision of high-voltage safety in motor drives or automation devices.
