IS4N46 Description

Short technical summary and product information.

The IS4N46 from Isocom Components is a 6-pin dual-in-line optically coupled isolator. It consists of an infrared light-emitting diode and a NPN silicon photo darlington. This device is designed for applications requiring high voltage and current capability, offering a high isolation voltage of 5.3kVRMS and a typical current transfer ratio of 1500%.

Key features include a high BVCEO of 55V minimum and an internal base-emitter resistor that minimizes output leakage. The device operates with a low input current of 0.5mA IF. It is suitable for various applications such as digital logic ground isolation, level shifting, and interfacing between logic families.

The IS4N46 is available in a standard 6-pin dual-in-line plastic package. Options for lead spread (G) and surface mounting (SM) are available. The operating temperature range is -25°C to +100°C, with a storage temperature range of -40°C to +125°C.
