Overview
The Broadcom Limited 4N35-W00E is a single-channel transistor output optocoupler housed in a PDIP-wide-6 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 isolation voltage of 3550 VRMS. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.5 V, and a reverse voltage of 6 V. Power dissipation is rated at 350 mW, with rise and fall times of 10 µs each.
Feature Summary
- Provides galvanic isolation between input and output circuits via an internal LED and phototransistor structure.
- Utilizes an NPN phototransistor output stage suitable for switching applications requiring moderate current drive capabilities.
- Designed for through-hole mounting using a standard six-pin wide DIP configuration.
Applications
- General-purpose signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller interface circuits requiring voltage level shifting
Procurement Notes
Verify the specific suffix W00E against the official Broadcom datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the required PDIP-6 package variant. Cross-reference manufacturer documentation for any updates regarding component availability or recommended operating conditions prior to final procurement decisions.
Selection Notes
Select this component when a standard bipolar transistor output optocoupler is required for basic isolation tasks. Consider the 10 µs switching speed limitations compared to high-speed alternatives. Evaluate the 3550 VRMS isolation rating against system safety requirements. Confirm that the 100 mA collector current meets load demands without exceeding thermal limits.
Part Context
This component belongs to the broader family of transistor output optocouplers manufactured by Broadcom Limited. It serves as a legacy general-purpose isolation device often used in established designs. The product line includes various packages and speed variants, but this specific model focuses on standard switching performance within a widely available through-hole form factor.
Replacement Considerations
Consult official substitution guides for equivalent parts such as the HCPL-2630 for higher speed requirements or other generic 4N35 equivalents from different manufacturers if pin compatibility is critical. Verify functional equivalence rather than assuming direct interchangeability across all electrical parameters.
