3N261 Description

Short technical summary and product information.

The Optek Technology 3N261 is an optocoupler featuring an infrared LED coupled to a silicon phototransistor within a hermetic TO-18 package. This component is designed for high reliability and stability over a wide temperature range, operating from -55°C to +125°C.

 

Key electrical specifications include a maximum input-to-output voltage of 1000V, a collector-emitter breakdown voltage of 40V, and an emitter-collector breakdown voltage of 7V. The continuous forward current for the input diode is rated at 40mA, and the continuous collector current is 20mA. The device has a maximum power dissipation of 190mW at 25°C free-air temperature.

 

The 3N261 is electrically similar to the 4N47, 4N48, and 4N49 series. Its design includes an eliminated base lead for improved noise immunity, and the collector is in electrical contact with the case. The TO-18 package is suitable for through-hole mounting.

 

Applications for the 3N261 include eliminating ground loops, level shifting, line receivers, switching power supplies, and motor control. Its rugged package and high electrical isolation make it a versatile component for various industrial and electronic systems.
