Overview
The Broadcom Limited 4N25-000E 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 current of 100 mA and a collector-emitter voltage rating of 30 V. The device provides 2500 Vrms insulation voltage for circuit isolation. Key electrical parameters include a minimum current transfer ratio of 20%, a forward voltage of 1.5 V, and a maximum collector-emitter saturation voltage of 500 mV.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor pair.
- Designed for general-purpose signal switching and logic interface applications requiring reliable digital transmission.
- Offers high common-mode transient immunity to protect sensitive control circuits from electrical noise.
Applications
- Logic level shifting between different voltage domains
- Switching power supply feedback loops
- General-purpose digital signal isolation
Procurement Notes
Verify the manufacturer part number matches Broadcom Limited exactly. Confirm the suffix indicates the standard PDIP-6 package. Check RoHS compliance status as specified in the official datasheet. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when a low-cost, general-purpose optocoupler is required for basic isolation tasks. It is suitable for applications where high-speed performance is not critical but robust DC or low-frequency signal transmission is needed. Consider the 20% minimum CTR for drive circuit design margins.
Part Context
This component belongs to the standard 4N25 series of transistor output optocouplers manufactured by Broadcom Limited. It is widely used in industrial and consumer electronics for basic isolation needs. The 4N25 series is known for its reliability and cost-effectiveness in legacy and modern designs alike.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing footprints and electrical requirements before considering alternative manufacturers.
