4N33TVM

Overview

The onsemi 4N33TVM is a single-channel optocoupler featuring a Darlington transistor output with a base lead, housed in a 6-pin PDIP package. It provides high isolation voltage of 4170 Vrms and supports DC input. The device operates within a temperature range of -40°C to +100°C, with a typical rise time of 5μs and a maximum forward voltage of 1.5V.

Feature Summary

• Integrates a Darlington compound transistor output for high current transfer ratio
• Includes an internal base connection to facilitate faster switching speeds
• Offers robust electrical isolation capability suitable for sensitive circuits

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'TVM' corresponds to the tube packaging format as indicated by distributor listings. Confirm RoHS compliance status through official datasheets prior to integration. Ensure the 6-pin DIP footprint matches the target PCB design constraints.

Selection Notes

Select this component when high gain is required due to the Darlington configuration. Consider the inclusion of the base pin if improved switching performance over standard variants is necessary. Verify that the 4170 Vrms isolation rating meets the safety requirements of the application environment.

Part Context

This part belongs to the 4N33 series of optocouplers manufactured by onsemi. It is designed for general-purpose isolation applications where high current transfer ratios are beneficial. The device utilizes a silicon photodiode input coupled to a Darlington output structure.

Replacement Considerations

Direct substitutes include other 4N33 series variants such as the 4N33M or 4N33 from compatible manufacturers, provided they share the same 6-pin DIP package and electrical characteristics.
