4N28-X001

Overview

The Vishay 4N28-X001 is a single-channel optoisolator featuring an NPN phototransistor output with a base connection. It provides 5000Vrms isolation voltage and supports a maximum collector-emitter voltage of 70V. The device operates within a temperature range of -55°C to 110°C and utilizes a 6-DIP package. Key electrical characteristics include a minimum current transfer ratio of 10% at 10mA forward current, a typical fall time of 2µs, and a maximum DC forward current of 60mA.

Feature Summary

Integrated base connection on the phototransistor output for improved switching speed and linearity control
High isolation voltage capability of 5000Vrms for robust signal separation between input and output circuits
Wide operating temperature range extending from -55°C to 110°C for reliable performance in harsh environments

Applications

AC mains detection circuits requiring high-voltage isolation
General-purpose signal isolation in industrial control systems
Switching power supply feedback loops

Procurement Notes

Verify that the specific suffix X001 corresponds to the standard tube packaging configuration as defined by Vishay Semiconductor Opto Division. Confirm RoHS3 compliance status for the specific production lot. Ensure the 6-DIP pinout matches the target PCB footprint design requirements before finalizing procurement orders.

Selection Notes

Select this component when a phototransistor output with a base terminal is required for faster switching or linear operation compared to standard variants. Consider the 5000Vrms isolation rating for safety-critical applications. Evaluate the 10% minimum CTR against circuit gain requirements to ensure proper logic level translation under all operating conditions.

Part Context

The 4N28-X001 belongs to the Vishay 4N2x series of phototransistor output optocouplers. This family is characterized by its silicon gate structure and epoxy encapsulation. The part serves as a general-purpose isolator, distinct from high-speed logic output or thyristor output variants within the broader Vishay optoelectronics portfolio.
