Overview
The Broadcom Limited 4N25-560E is a single-channel transistor output optocoupler designed for surface mount applications. It features an NPN phototransistor output with a base terminal, providing electrical isolation rated at 2500 Vrms. The device supports a maximum forward current of 80 mA and can handle a collector current up to 100 mA. Key electrical parameters include a collector-emitter voltage of 30 V, a minimum current transfer ratio of 20%, and typical rise and fall times of 3 microseconds. It operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD package.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor featuring a base terminal for improved switching performance.
Applications
- General-purpose signal isolation in industrial control systems
- Interface between microcontrollers and high-voltage circuits
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix (560E) to confirm the surface-mount tape-and-reel packaging configuration. Ensure compatibility with the required isolation voltage rating of 2500 Vrms for the target application environment. Confirm RoHS compliance status through official manufacturer documentation prior to integration.
Selection Notes
Select this component when a surface-mount footprint is required for standard transistor-output isolation. The inclusion of a base terminal allows for faster turn-off times compared to devices without this feature. Consider the 2500 Vrms isolation barrier and 80 mA forward current capability against system requirements.
Part Context
This part belongs to the 4N25 series of transistor output optocouplers manufactured by Broadcom Limited. The series is widely recognized for general-purpose isolation tasks. The 560E suffix specifically denotes the surface-mount variant, distinguishing it from through-hole packages like the PDIP-6 found in other variants such as the 4N25-000E.
FAQ
What is the purpose of the base terminal on the phototransistor?
The base terminal allows for external connection to improve the switching speed, particularly reducing the turn-off time of the phototransistor.
What is the maximum operating temperature for this device?
The maximum operating temperature is +100°C.
