MTL6400U is a single channel optocoupler with high reliability and high current ratio. It is housed in a rugged surface mount package and has a low input current requirement. It provides +1.5kV electrical isolation and is suitable for applications such as military, space, level shifting, line receiver, switching power supplies, and communication systems.
The MTL6400U is a single‑channel optocoupler built in a 6‑pin leadless chip carrier. It features high reliability for military and space, high current transfer ratio, low input current (0.5 mA), and a rugged surface‑mount package. The device provides up to 4.5 kV electrical isolation and is available with MIL‑STD‑883 screening.
The datasheet lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics such as input reverse breakdown voltage, forward voltage, current transfer ratio, and logic‑level output specifications. A selection guide shows part‑number variants for different temperature ranges, and package dimensions and a schematic diagram are included.
