SFH615A-1X017

Overview

The SFH615A-1X017 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70V and a peak forward current rating of 60mA. The device provides high isolation capability with an insulation voltage of 5300Vrms. Key electrical parameters include a minimum current transfer ratio of 40% and a maximum of 80%, measured at a forward current of 10mA. The typical rise time is 2µs, while the fall time is specified at 11µs. The component operates within a temperature range of -55°C to +100°C and utilizes a 4-SMD surface-mount package.

Feature Summary

• High isolation voltage rating of 5300Vrms for robust circuit separation
• NPN phototransistor output configuration for standard switching applications
• Wide operating temperature range supporting extreme environmental conditions
• Low coupling capacitance design for improved signal integrity

Applications

• General-purpose digital signal isolation in industrial control systems
• Power supply feedback loops requiring galvanic isolation
• Interface circuits between microcontrollers and high-voltage loads
• Safety-critical equipment adhering to IEC 60950 standards

Procurement Notes

Verify the specific suffix '1X017' against the official Vishay datasheet to confirm the exact pinout, tape-and-reel specifications, and compliance certifications. Ensure that the procurement source provides valid RoHS documentation and UL recognition details. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the delivered units match the 4-SMD package dimensions and lead-free requirements specified in the product data sheet.

Selection Notes

Select this component when a single-channel isolation barrier with moderate speed characteristics is required. The 40-80% current transfer ratio range suits applications where consistent gain is necessary without excessive drive current. Consider the 70V collector-emitter voltage limit for low-voltage switching tasks. The surface-mount form factor is suitable for compact PCB layouts. Evaluate thermal dissipation requirements if operating near the upper temperature limit of 100°C.

Part Context

This device belongs to the SFH615A series of high-reliability optocouplers from Vishay. The series is designed for general-purpose isolation applications with strict safety standards. The SFH615A-1X017 variant specifically denotes the surface-mount version with defined electrical tolerances. It complements through-hole variants like the SFH615A-1 by offering equivalent performance in a smaller footprint. The series supports various industry certifications including VDE and cUL.

Replacement Considerations

Public confirmed substitute part numbers include SFH615A-1X017T for identical specifications in tape-and-reel packaging. Direct cross-model replacements are not explicitly documented in the provided source material; verify compatibility with alternative manufacturers only through independent parameter matching.
