SFH615A-3XSM

Overview

The SFH615A-3XSM is a single-channel optocoupler manufactured by Isocom Components, featuring an NPN phototransistor output. It provides high isolation voltage of 5000 Vrms and supports a collector current of 50 mA with a maximum collector-emitter voltage of 70 V. The device operates within a temperature range of -30°C to 100°C and offers a minimum current transfer ratio of 160% at 10 mA input current. Typical switching times include 6 µs for turn-on and 25 µs for turn-off. It is housed in a compact 4-SMD鸥翼 (gull-wing) package suitable for surface-mount applications.

Feature Summary

• Provides reliable electrical isolation between input and output circuits using infrared LED and NPN phototransistor technology.
• Features a high current transfer ratio ensuring efficient signal transmission with low input drive requirements.
• Designed for robust performance in industrial environments with wide operating temperature capabilities.

Applications

• Industrial control systems requiring logic-to-logic isolation
• Power supply protection circuits
• Signal isolation in automated equipment

Procurement Notes

Verify the specific suffix '3XSM' against official Isocom documentation to confirm pinout configuration and tape/reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing process. Cross-reference datasheet parameters such as CTR and isolation voltage with your circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is preferred over through-hole DIP packages while maintaining standard transistor output characteristics. Consider the 4-SMD gull-wing footprint for PCB space constraints. Evaluate the 5000 Vrms isolation rating against system safety standards and verify that the 50 mA output current capability meets load requirements.
