4N25-300E

Overview

The Broadcom Limited 4N25-300E is a single-channel transistor output optocoupler housed in a PDIP-6 gull wing package. It provides an isolation voltage of 2500 Vrms and supports a maximum forward current of 80 mA with a forward voltage of 1.5 V. The device features an NPN phototransistor output capable of handling a maximum collector current of 100 mA and a collector-emitter voltage of 30 V. It ensures reliable signal transmission between circuits with different potentials, maintaining a minimum current transfer ratio of 20%.

Feature Summary

Provides electrical isolation for signal transmission between circuits operating at different potentials
Utilizes an NPN phototransistor output configuration for digital switching applications
Offers high insulation voltage capability to protect sensitive components from high voltage transients

Applications

Signal isolation in microprocessor systems
Switching power supply feedback loops
Industrial control circuit interfacing

Procurement Notes

Verify the specific suffix '300E' corresponds to the required tape and reel packaging format rather than standard tube packaging. Confirm RoHS compliance status matches project requirements. Ensure the PDIP-6 package dimensions align with the target PCB footprint. Cross-reference the manufacturer part number with official Broadcom documentation to validate authenticity and revision level before procurement.

Selection Notes

Select this component when a cost-effective, general-purpose optocoupler with moderate speed and high isolation voltage is required. It is suitable for applications where the input LED drives a simple NPN phototransistor load. Consider the 2500 Vrms isolation rating for safety-critical interfaces. Evaluate the 80 mA forward current limit against drive circuit capabilities to ensure proper operation within specified parameters.

Part Context

This component belongs to the widely used 4N25 series of transistor output optocouplers manufactured by Broadcom Limited. The series is known for providing basic isolation between low-voltage control logic and higher-voltage power stages. The 4N25-300E variant specifically denotes the surface-mount compatible DIP-6 package configuration available through authorized distribution channels.
