Photocoupler Achieves 8mm Creepage Distance

Renesas Electronics Corp. has launched a new compact, slim photocoupler, the PS2381-1, that achieves long creepage distance of 8mm required by the worldwide safety standards.

The device is mounted in a 4-pin LSOP (long small outline package) in which the shortest distance between the LED (Light-Emitting Diode) side pin and the photo detector side pin along the package surface (the creepage distance) is 8mm. This package achieves an insulation thickness of 0.4mm, which is the shortest distance between the LED device and the photo detector device that are isolated within the package. In addition to these features, the new photocoupler is designed to provide package thickness of 2.3mm, reduced by 40 percent from the existing 4-pin DIP (Dual-Inline package), and an operating ambient temperature of 115°C as well as a guaranteed isolation voltage of 5kVrms, maintaining the same voltage as the 4-pin DIP package.
