SFH620A-1G

Overview

The SFH620A-1G is a single-channel optocoupler featuring inverse parallel infrared LEDs and an NPN silicon phototransistor. It provides high isolation with a minimum input-to-output voltage of 5300 Vrms and a peak withstand of 7500 Vpk. The device operates within a temperature range of -30°C to 100°C, supporting a maximum DC forward current of 50 mA. Key electrical parameters include a typical rise time of 4 µs, a fall time of 3 µs, and a collector-emitter saturation voltage of 0.4 V at specified test conditions.

Feature Summary

Features inverse parallel infrared light emitting diodes for AC input compatibility
Utilizes NPN silicon phototransistor output for reliable signal transmission
Provides high-voltage insulation suitable for demanding industrial environments

Applications

Logic-to-logic isolation in noisy work environments
Line receiver circuits
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix (e.g., -1G, -3XG) against project requirements, as variations may indicate different packaging or compliance standards. Confirm that the DIP-4 through-hole package aligns with PCB layout constraints. Ensure the 5300 Vrms isolation rating meets safety certification requirements for the target application. Cross-reference the operating temperature range with environmental specifications.

Selection Notes

Select this component when AC input capability is required due to the inverse parallel LED configuration. The NPN phototransistor output suits general switching applications. Consider the 5300 Vrms isolation barrier for high-voltage separation needs. Evaluate the 4 µs/3 µs timing characteristics against system speed requirements. The wide operating temperature range supports diverse environmental conditions.
