4N35-X019T

Overview

The Vishay 4N35-X019T is a single-channel transistor output optocoupler housed in a 6-SMD gull-wing package. It features an NPN phototransistor with a base lead for improved switching performance. Key electrical parameters include a minimum current transfer ratio of 100% at 10 mA input, a maximum collector-emitter voltage of 30 V, and a peak forward current of 60 mA. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C.

Feature Summary

Integrates an NPN phototransistor with a dedicated base terminal to enhance switching speed and reduce storage time compared to standard configurations.
Provides robust galvanic isolation between input and output circuits via a 5000 Vrms dielectric barrier.
Delivers high current transfer efficiency with a guaranteed minimum CTR of 100% under specified test conditions.

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessors and logic systems
Switching power supply feedback loops

Procurement Notes

Verify the specific suffix 'X019T' against the manufacturer's latest datasheet to confirm pinout compatibility and mechanical dimensions. Ensure that the required current transfer ratio meets the application threshold, as variations exist within the 4N35 family. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering.

Selection Notes

Select this component when surface-mount assembly is required for a classic transistor-output isolator. The integrated base lead offers superior turn-off times compared to devices without a base connection. Consider the 6-SMD form factor for space-constrained PCB layouts where through-hole packages are unsuitable.

Part Context

This part belongs to the 4N35-X series, which adapts the traditional 4N35 transistor output topology for modern surface-mount manufacturing processes. It maintains the functional equivalence of legacy DIP-6 versions while offering automated placement compatibility. The series is widely recognized for general-purpose digital signal isolation tasks.
