4N35

Overview

The Vishay 4N35 is a single-channel phototransistor optocoupler featuring an infrared LED and silicon NPN output. It provides 5000Vrms isolation via double molding. Key electrical parameters include a maximum collector-emitter voltage of 30V, peak forward current of 60mA, and typical rise/fall times of 10µs. The device operates within a temperature range of -55°C to 100°C and offers a minimum current transfer ratio of 100% at 10mA input.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Integrates an infrared emitting diode with a silicon NPN phototransistor
Features a base connection on the phototransistor for improved switching speed

Applications

AC mains detection circuits
Reed relay driving interfaces
Switch mode power supply feedback loops
Telephone ring detection systems
Logic ground isolation applications

Procurement Notes

Verify the specific suffix (e.g., X007T, X009T) against project requirements to ensure correct packaging and mechanical configuration. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Cross-reference official datasheets for precise thermal and electrical limits to validate suitability for the intended operating environment.

Selection Notes

Select this component for cost-effective general-purpose isolation where moderate switching speeds are acceptable. The standard DIP-6 package suits through-hole designs, while SMD variants support surface mount assembly. Ensure the required isolation voltage and current transfer ratio meet circuit specifications before finalizing the part number selection.

Part Context

The 4N35 belongs to a family of industry-standard single-channel phototransistor couplers manufactured by Vishay. This series includes related models such as the 4N36, 4N37, and 4N38, which share similar functional characteristics but may differ in specific electrical ratings or packaging options. The family is widely recognized for reliable performance in commercial plastic optocoupler applications.
