SFH615AGR-X001

Overview

The SFH615AGR-X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a PDIP-4 package for through-hole mounting. The device provides high isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a collector-emitter breakdown voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation rating of 150 mW. The forward current is specified at 60 mA with a forward voltage of 1.65 V. The current transfer ratio ranges from 40% to 80%. Switching characteristics include a rise time of 2 µs and a fall time of 11 µs. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
• Features a standard four-pin DIP package designed for reliable through-hole PCB mounting.
• Supports high-voltage isolation capabilities suitable for noise-immune signal transmission in digital applications.

Applications

• Digital signal isolation in microprocessor-based systems
• Switch-mode power supply feedback loops
• Industrial control circuit interfacing

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the PDIP-4 package type aligns with the target printed circuit board layout requirements. Check for RoHS compliance status as indicated in the latest datasheet revision. Ensure that the thermal management strategy accounts for the 150 mW power dissipation limit during operation.

Selection Notes

Select this component when high isolation voltage and moderate switching speed are required for single-channel digital isolation. Compare the 40-80% current transfer ratio against system gain requirements. Evaluate the 2 µs rise time against the maximum data rate needed for the application. Consider the PDIP-4 form factor if surface-mount alternatives like the VOS series are unsuitable for the assembly process.
