Overview
The Broadcom Limited 4N35-360E is a single-channel transistor output optocoupler housed in a PDIP-6 Gull Wing surface-mount package. It features an NPN phototransistor output with a maximum collector current of 100 mA and a collector-emitter voltage rating of 30 V. The device provides an insulation voltage of 3550 Vrms and supports a forward current of 60 mA with a forward voltage of 1.5 V. Key switching parameters include a rise time and fall time of 10 µs, a power dissipation of 350 mW, and a reverse voltage of 6 V. Operating temperatures range from -55°C to +100°C.
Feature Summary
- Provides electrical isolation via an infrared LED coupled to an NPN phototransistor output.
- Designed for general-purpose signal transmission with high insulation voltage capabilities.
- Utilizes a six-lead gull-wing surface mount package for compact circuit integration.
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits between microprocessors and peripheral devices
- Switching applications requiring moderate speed and high isolation
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Ensure storage conditions meet specified temperature limits to maintain performance integrity given the component's discontinued lifecycle status.
Selection Notes
Select this component when a standard NPN phototransistor output is required with a 3550 Vrms isolation barrier. Consider the 10 µs switching speed suitable for low-frequency digital signals. Evaluate the 100 mA collector current capacity against load requirements. Compare against alternative packages if space constraints differ from the PDIP-6 form factor.
Part Context
This part belongs to the 4N series of optocouplers manufactured by Broadcom Limited. It represents a legacy component within the company's semiconductor portfolio, historically widely used for basic isolation tasks. The 4N35 variant is a standard industry reference for general-purpose optoisolation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent generic 4N35 variants from other manufacturers, ensuring pinout and electrical specifications match exactly.
