SFH615A-1SM

Overview

The SFH615A-1SM is a single-channel optocoupler featuring an infrared LED coupled to an NPN silicon phototransistor in a surface-mount package. It provides an AC isolation voltage of 5300 VRMS and supports a peak input current of 7500 VPK. The device operates with a low input current of 1 mA and offers high current transfer ratios across a wide operating temperature range, suitable for compact circuit designs requiring electrical isolation.

Feature Summary

Integrates an infrared light emitting diode with an NPN silicon phototransistor for signal transmission
Provides robust electrical isolation with an AC isolation voltage rating of 5300 VRMS
Designed for space-efficient applications using a surface-mount configuration
Operates effectively with low input current requirements

Applications

Logic-to-logic isolators in noisy environments
Line receivers
Programmable current level sensors
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix '1SM' against official Isocom documentation to confirm the exact pinout and package dimensions, as variations exist within the SFH615A series. Ensure compatibility with surface-mount assembly processes. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or regional certification status before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount form factor is required for single-channel isolation. The 5300 VRMS rating makes it suitable for mains-connected applications. Consider the low input current requirement for power-sensitive designs. Verify that the NPN transistor output type aligns with the downstream logic interface requirements of the target circuit design.
