4N24A

Overview

The 4N24A is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It features an NPN phototransistor with a base terminal for improved switching performance and isolation stability. The device provides 1000VDC isolation voltage between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 35V, a collector current rating of 50mA, and a DC forward current limit of 40mA. The typical rise and fall times are 20µs each. It operates within a temperature range of -65°C to 125°C and is housed in a TO-78-6 metal can package.

Feature Summary

Integrates an NPN phototransistor with a dedicated base terminal to enhance switching speed and reduce storage time.
Provides robust galvanic isolation with a 1000VDC insulation voltage rating for safety-critical applications.
Utilizes a hermetically sealed TO-78-6 metal can package to ensure reliability in harsh environments.

Applications

Industrial control systems requiring signal isolation
Solid-state relay driver circuits
Microcontroller interface isolation

Procurement Notes

Verify the specific suffix (e.g., A, TX, TXV) against the datasheet to confirm pinout and packaging variations. Confirm RoHS compliance status as it varies by manufacturing batch and region. Check for obsolete status or end-of-life notices from the manufacturer before finalizing design-in decisions.

Selection Notes

Select this component when high-speed switching is required compared to standard variants without a base terminal. Ensure the application voltage does not exceed the 35V collector-emitter rating. Consider the TO-78-6 package constraints for PCB layout and thermal management requirements.

Part Context

The 4N24A belongs to the HCC24 series of transistor output optocouplers from TT Electronics/Optek Technology. This series is designed for general-purpose isolation tasks where faster response times than basic models are necessary. It serves as a direct functional replacement for other industry-standard 4N24 devices.
