High-speed optocouplers with high isolation voltage and extended operating temperature range

Ideally suited for applications in harsh industrial environments

(PresseBox) (Stutensee (Germany), ) MSC now offers two new high-speed optocouplers, the PS9123 and the PS9324, from Renesas Electronics. The new optocouplers feature a high communication bandwidth of 10 Mbit/s, a maximum isolation voltage of 5 kVrms and an extended operating temperature range from -40°C to +100°C for the PS9123 series and up to 110°C for the PS9324 series.

The PS9324 series has an open collector output and the maximum propagation delay time is specified as 75 ns at 25°C. The PS9123 series comes with a totem pole output, offering shorter propagation delay times as low as 65 ns at 25°C. The maximum pulse width distortion |tPHL tPLH| is less than 35 ns for the PS9324 series and less than 50 ns for the PS9123 series.

Furthermore, for operation in noisy industrial environments, the new high-performance optocouplers have an internal shield providing a common-mode transient immunity (CMTI) of minimum 15 kV/µs and typical values of 20 kV/µs.

The PS9324 optocouplers come in a small 6-pin shrink dual inline package (SDIP). The small package reduces the mounting space by 50 percent compared to a conventional 8-pin DIP package while guaranteeing a maximum isolation voltage of 5 kVrms and achieving a minimum creepage current distance of 8 mm (PS9324L2). The PS9123 is delivered in a 5-pin small outline package (SOP), allowing space saving designs.

The PS9123 series and the PS9324 series are optically-coupled high-speed isolators containing an integrated signal processing circuit and can be operated from a 2.7 V to 5.5 V supply voltage. Furthermore, the new devices comply with international safety standards such as UL, CSA and VDE (optional), making them ideally suited for applications in harsh industrial environments such as factory automation, measurement equipment and motor-control.

Samples of the new PS9123 and PS9324 series of optocouplers are available now. Detailed information can be requested by sending an email to power-devices@msc-ge.com.
