Renesas announces the availability of two IC-output optocouplers with long-creepage-distance for applications such as industrial equipment employing the maximum commercial power supply voltage of 690 V or solar power generation systems employing high voltages of up to 1,000 V. The PS9924 is a high-speed optocoupler supporting internal system communication speeds of 10 Mb/s and the PS9905 is an optically coupled 2.5 A IGBT driver featuring high speed switching performance and reduced output voltage drop due to MOSFET-MOSFET output form.
The PS99XX Series devices are housed in a novel 8-pin Long-SDIP package, which combines the small pin pitch (1.27 mm) with increased distance between the input and the output. Thus despite small space requirement outstanding isolation properties are achieved. In addition to a minimum external creepage distance of 14.5 mm, the device is specified for an isolation voltage of 7500 Vrms.
The new devices comply with the international safety standards such as UL, CSA, and VDE (optional) making these ideally suited for deployment in harsh application environments like motor control, measuring instruments as well as factory automation.The PS9924 is designed for 10 Mb/s bandwidth operations over an extended temperature range from -40 to +110°C. The detector IC of the “active low” type PS9924 features an open collector output and low operation voltages from 2.7 V to 5.5 V allowing a flexible circuit design. Thanks to specified maximum propagation delay time of 75 ns and typical value of 40 ns at 25°C, a communication bandwidth of 10 Mb/s can be achieved. For safe operations in noisy industrial environment, the new optocoupler incorporates an internal shield providing common-mode transient rejection of minimum 15 kV/µs and typical values of 20 kV/µs. The PS9924 delivers low power consumption characteristics making it ideal for applications requiring both high insulation voltage and low power consumption.
