Overview
The Broadcom Limited 4N35-000E is a single-channel transistor output optocoupler housed in a PDIP-wide-6 package. It features an infrared LED optically coupled to an NPN phototransistor with a base terminal for improved switching characteristics. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a peak forward current of 60 mA, and a typical forward voltage of 1.2 V to 1.5 V. The device provides an isolation voltage of 3550 Vrms and supports a maximum collector current of 100 mA. Power dissipation is rated at 350 mW, with rise and fall times of approximately 10 µs.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical coupling technology.
- Integrates an NPN phototransistor with a dedicated base terminal to enhance switching speed and stability.
- Designed for general-purpose signal transmission and impedance transformation applications.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation isolation between circuit stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure compliance with RoHS standards and lead time requirements. Confirm that the package type matches the required PCB footprint. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement decisions.
Selection Notes
Select this component when a standard transistor output optocoupler with base access is required for moderate-speed digital isolation. Consider the 3550 Vrms isolation rating for safety-critical interfaces. Evaluate the 10 µs switching speed against system timing requirements to ensure adequate performance for the intended application frequency.
Part Context
The 4N35 series is a widely recognized family of general-purpose optocouplers manufactured by Broadcom Limited (formerly Avago). The 4N35-000E represents the standard variant within this lineage, maintaining compatibility with legacy designs while adhering to modern environmental directives. It serves as a foundational component for basic isolation tasks in industrial and consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the available source material. Consult official cross-reference guides or manufacturer recommendations for verified alternatives if direct replacement is necessary.
