Overview
The SFH615AA-X007 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It utilizes a gallium arsenide infrared LED coupled to an NPN phototransistor within a compact SMD-4 surface mount package. The device provides high isolation voltage of 5300 Vrms and supports a maximum collector current of 50 mA with a collector-emitter voltage rating of 70 V. Key electrical characteristics include a forward voltage of approximately 1.25 V, a typical rise time of 3 µs, and a fall time of 4.7 µs. It operates reliably across a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for robust circuit protection
- Low coupling capacitance for improved signal integrity
- Compact surface mount packaging for automated assembly
Applications
- General-purpose signal isolation in industrial control systems
- Interface between microcontrollers and power circuits
- Isolation in measurement and testing equipment
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm exact Current Transfer Ratio (CTR) binning and tape/reel specifications. Ensure the ordering part number matches the required package variant and compliance status. Cross-reference datasheet parameters such as isolation voltage and operating temperature range with system requirements before finalizing procurement orders.
Selection Notes
Select this component when a surface mount solution with high isolation voltage is required for single-channel applications. Consider the NPN phototransistor output configuration and switching speed characteristics relative to the application's timing constraints. Evaluate the thermal management needs based on the specified power dissipation and operating temperature limits.
Part Context
This component belongs to the SFH615XXX series of optocouplers from Vishay. The series is characterized by a large assortment of current transfer ratios and low coupling capacitance. It serves as a surface mount alternative to through-hole variants like the VO615A or SFH615A families, offering similar electrical performance in a smaller footprint suitable for modern PCB designs.
Replacement Considerations
The VO615A-X007T is documented as a recommended alternative. Verify pinout compatibility and parameter alignment, particularly regarding CTR ranges and isolation voltage ratings, before substituting.
