The Broadcom Limited 4N35-060E is a single-channel transistor output optocoupler housed in a PDIP-6 through-hole package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 30 V and a maximum collector current of 100 mA. The device provides an isolation voltage of 3550 Vrms and supports a forward current of 60 mA with a typical forward voltage of 1.5 V. The collector-emitter saturation voltage is specified at a maximum of 300 mV. This component is currently listed as obsolete by the manufacturer.
Verify availability status carefully, as this specific part number is officially marked as obsolete or discontinued by Broadcom Limited. Sourcing may require checking secondary market distributors or identifying valid replacement components from the same manufacturer family. Ensure that any substitute parts meet the required isolation voltage and pin compatibility specifications before integration into existing designs.
Select this component only if legacy design compatibility with the PDIP-6 package and NPN output characteristics is strictly required. Consider modern alternatives within the Broadcom portfolio that offer improved speed or higher reliability ratings if the application permits redesign. Evaluate whether the standard switching speed meets the timing requirements of the target system without necessitating faster optocouplers.
The 4N35 series represents a long-standing line of general-purpose optocouplers widely used in industrial and consumer electronics. The 4N35-060E variant specifically denotes the lead-free and halogen-free compliant version of the standard 4N35 device. It belongs to the broader category of transistor output optocouplers, serving as a fundamental building block for noise immunity and ground loop elimination in electronic systems.
