The IS6051 is an optically coupled isolator consisting of infrared light emitting diode and a light activated silicon controlled rectifier in a standard 6pin dual in line plastic package.
The IS6051 is an optically coupled isolator that combines an infrared light‑emitting diode with a light‑activated silicon controlled rectifier in a 6‑pin DIP package. It is designed for applications such as solid‑state relays, logic indicator lamp drivers, and high‑voltage transistor couplers.
Key features include low turn‑on current (5 mA typical), high isolation voltage (5.3 kV), high surge anode current (5 A), and a range of package options (lead‑spread, surface‑mount, tape‑and‑reel). The device is UL recognised (File No. E91231) and operates over a wide temperature range.
