4N30SD

Overview

The onsemi 4N30SD is a single-channel transistor output optocoupler featuring a photodarlington detector. It utilizes an SMD-DIP-6 surface mount package for through-hole compatibility. The device provides high isolation voltage of 5300 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a forward current of 80 mA, and a power dissipation rating of 250 mW. It operates within a temperature range of -55°C to +125°C.

Feature Summary

Photodarlington output configuration for high gain sensitivity
Surface mount DIP-6 package design for automated assembly
High insulation voltage capability for circuit isolation

Applications

General purpose signal isolation in industrial control systems
Microprocessor interface circuits requiring galvanic separation
Solid-state relay driver applications

Procurement Notes

Verify component authenticity and datasheet revisions upon acquisition. Confirm the specific suffix matches the required pinout and isolation specifications. Check for obsolescence status as availability may be limited. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Validate compliance with relevant environmental directives before integration into final products.

Selection Notes

Select this component when surface mount processing is required alongside the electrical characteristics of the standard 4N30 series. The photodarlington output offers higher current transfer ratio compared to standard phototransistor variants. Consider the SMD-DIP footprint if board space constraints preclude standard DIP packages but through-hole reliability is desired. Verify thermal management requirements given the 250 mW power dissipation limit.

Part Context

This part belongs to the general-purpose photodarlington optocoupler family from onsemi. It serves as the surface mount equivalent to the legacy through-hole 4N30 component. The series is designed for cost-effective isolation in digital and analog signal transmission paths where moderate speed and high gain are prioritized over switching frequency.
