SFH620A-3X

Overview

The SFH620A-3X 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 voltage of 7500 Vpk. The device supports a maximum forward current of ±50 mA and a typical forward voltage of 1.65 V. Electrical performance includes a minimum current transfer ratio of 100% and a maximum of 320%, with collector-emitter saturation voltage at 0.4 V. Switching characteristics are defined by typical rise and fall times of 4 µs and 3 µs, respectively.

Feature Summary

AC input capability enabled by inverse parallel infrared LED configuration
High-voltage insulation for robust circuit protection
NPN phototransistor output for digital signal transmission

Applications

Logic-to-logic isolation in noisy environments
Line receiver circuits
Programmable current level sensors
Digital control of motors and servo machines

Procurement Notes

Verify the specific suffix '3X' against official Isocom documentation to confirm pinout and electrical tolerances. Ensure compliance requirements such as UL and VDE certifications match project specifications. Confirm package type and lead-free status if RoHS compliance is mandatory. Cross-reference datasheet parameters with system design limits before integration.

Selection Notes

Select this component for applications requiring AC input compatibility without external rectification. The high isolation voltage suits mains-connected interfaces. Evaluate current transfer ratio variations across temperature ranges. Consider switching speed limitations for high-frequency data transmission scenarios.

Part Context

The SFH620A series belongs to Isocom's lineup of transistor output optocouplers. These devices utilize space-saving DIP packaging. The series targets industrial and commercial replacement needs for legacy components. Designers use these isolators for galvanic separation between low-voltage logic and higher-voltage power stages.
