SFH615A-1

Overview

The SFH615A-1 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a current transfer ratio ranging from 40% to 80%. The device provides high isolation voltage of 5300 Vrms and supports through-hole installation in a PDIP-4 package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current of 60 mA. Operating temperatures range from -55°C to +100°C.

Feature Summary

Provides galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
Ensures signal integrity across isolated domains with specified current transfer ratio performance.
Supports reliable operation in harsh environments with extended temperature range capabilities.

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops for voltage regulation
Microcontroller interface circuits for level shifting

Procurement Notes

Verify the specific suffix designation to confirm package type and tape/reel specifications, as variations exist within the SFH615A family. Cross-reference the manufacturer datasheet for updated RoHS compliance status and recommended soldering profiles. Ensure that the procurement source provides authentic Vishay Semiconductor Opto Division components to guarantee performance reliability and adherence to specified electrical characteristics.

Selection Notes

Select this component when high isolation voltage and standard DIP packaging are required for through-hole assembly. Compare against surface mount alternatives like the SFH615A-1X017T if space constraints dictate SMD solutions. Evaluate the current transfer ratio range against circuit gain requirements to ensure proper switching thresholds are met under varying temperature conditions.

Part Context

This part belongs to the SFH615 series of high-reliability optocouplers designed for robust industrial applications. It serves as a direct replacement or equivalent for legacy components such as the VO615A-1, offering comparable electrical performance with enhanced isolation ratings. The series is characterized by its consistent CTR distribution and long-term stability.
