4N28(SHORT,F)

Overview

The 4N28(SHORT,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared emitting diode coupled to an NPN phototransistor with a base lead for improved switching performance. The device provides electrical isolation with a maximum insulation voltage of 2500 Vrms. Key electrical parameters include a collector-emitter breakdown voltage of 30 V, a maximum forward current of 60 mA, and a nominal current transfer ratio of 100%. It operates within a temperature range of -55 °C to +100 °C and is housed in a standard 6-pin DIP package.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Includes a base lead on the phototransistor to enhance switching speed and reduce storage time
Offers high current transfer efficiency for reliable signal transmission

Applications

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

Procurement Notes

Verify the specific suffix (SHORT,F) against official Toshiba documentation to confirm pin configuration and packaging details. Ensure compliance with RoHS directives as indicated in component specifications. Cross-reference datasheet revision levels to guarantee parameter accuracy for design integration.

Selection Notes

Select this component when base-driven phototransistor isolation is required for faster response times compared to standard variants. Confirm that the 30 V collector-emitter voltage rating meets circuit requirements. Evaluate thermal management needs given the operating temperature range up to +100 °C.

Part Context

This part belongs to the 4Nxx series of transistor output optocouplers from Toshiba. These devices are widely used for general-purpose isolation applications. The SHORT designation typically indicates a specific internal die attachment or lead frame variation affecting physical dimensions or thermal characteristics, while F denotes tape-and-reel packaging.

Replacement Considerations

Compatible substitutes include other single-channel transistor output optocouplers with similar isolation ratings and CTR values. Verify pinout compatibility and electrical limits before substitution.
