Overview
The SFH615AY is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The device provides an insulation voltage of 5300 Vrms and utilizes a PDIP-4 Gull Wing surface mount package.
Feature Summary
- Provides high-voltage isolation with 5300 Vrms insulation rating for safe signal transmission between circuits.
- Features an NPN phototransistor output capable of handling up to 100 mA collector current.
- Designed for robust operation across a wide industrial temperature range from -55°C to +100°C.
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Power supply feedback loops
Procurement Notes
Verify the specific suffix code against official datasheets to confirm current transfer ratio (CTR) binning and packaging type. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the component matches the exact Vishay part number to avoid substitution errors regarding pinout or electrical characteristics.
Selection Notes
Select this component when a high isolation voltage of 5300 Vrms is required alongside a high collector current capacity of 100 mA. The SMD gull-wing package facilitates automated assembly. Consider the CTR specifications relative to the driving circuit requirements to ensure proper switching performance within the specified temperature range.
Part Context
This component belongs to the SFH615 series of high-reliability optocouplers. The series offers various CTR options and packaging configurations, including through-hole and surface-mount variants, to suit different design constraints while maintaining consistent isolation and speed characteristics.
Replacement Considerations
Direct replacements must match the 5300 Vrms isolation, 100 mA collector current, and PDIP-4 SMD package. Verify CTR ranges and rise/fall times against original design specifications before substituting.
